Tom's Fuel Map Controller + TRD Racing Spark Plug

[AlainMikli]

:headbang::headbang:Got it from Japan

[lilredrocket]

Sweetness!!!!!

[BrazdonW]

info? :)

[AlainMikli]

info? :)

Some say, this product even not in the list of Tom's Japan website, so I can't find any info in the internet, only this

• Clips onto air flow sensor easily and can extend into Front panel
• No cutting of any wires
• ECU untouched
• Control air/fuel ratio
• 5 settings from effective fuel savings to more power
• At top setting power increase 20-25%, Driver has control
• Control hub compact, can be placed anywhere
• Applicable to all Toyota models manufactured from 2005 to 2009

[lilredrocket]

So how can we get these?

[AlainMikli]

About the Fuel Map Controller....I really don't know except from Japan.....

I'm not sure if there's any TRD Racing Spark Plug in US available? I only can find TRD "Sport" spark plug in ebay for $30 per one.

[t0m4s]

but how did you bought it? which website?

[kustom play]

theres toms dealers all over

i use to use one in toronto when i would order stuff in

im sure if your in a big city you could find one

[cali yaris]

How much does it cost, and where is the performance data?

[Gideon]

After a bit of driving, wouldn't the O2 sensor tell the ECU to fix the mixture after you adjusted it manually?

[cali yaris]

^ that seems likely, but who knows - the Blitz fuel controller works with the supercharger

[Gideon]

This is true, but after reading a few translations of the product description from a few Japanese websites, it states that the ECU remains untouched and the only wires to connect are spliced into the MAF. I'm sure the Blitz controller does a bit more than just alter the MAF signal like this unit apparently only does.

Edit: Heh, now I see the MAF splice connector sitting atop the box. Looks well designed!

[AlainMikli]

but how did you bought it? which website?

I bought it directly from Japan....I just have a short trip to Japan 2 weeks ago.....

[AlainMikli]

How much does it cost, and where is the performance data?

the retail on the box is 18900yen, and I can't find any performance data on the website......

may be you can contact Tom's US to see if they can give you any data:tongue:

[AlainMikli]

After a bit of driving, wouldn't the O2 sensor tell the ECU to fix the mixture after you adjusted it manually?

As I want to test the controller before I wire it inside the car, I just test it with a 20mins drive to dinner and then come back, and I try the "+2 rich", and "+3 rich" setting, and can really feel the different between +2 & +3....I can't believe this little stuff can give this power to the yaris......will ask some professional to test it again...and will try +4 & +5 later....

I asked the passenger on my car what's different between this morning( I drive the same passenger to lunch this morning) and now, he said he can really feel the car has more power, and ask me what did I done:tongue:


Can't wait to install the TRD spark plug with this controller:tongue:

[AlainMikli]

After a bit of driving, wouldn't the O2 sensor tell the ECU to fix the mixture after you adjusted it manually?

I dont know how it works....but you can only adjust the setting before you start the car, if not, the computer will mess up everything....that's what the sales told me....

[PETERPOOP]

put it on the dyno! lol. before and then with +5!!!!!!!!

[AlainMikli]

put it on the dyno! lol. before and then with +5!!!!!!!!

If I have a super charge, I will:headbang:

now, even this controller increase 10HP, my car is still only got <110HP, so forget about it, haha

or someone willing to pay me the dyno fee:biggrin:

[ROCKLAND TOYOTA]

any way you can read us the full number off those plugs?

[kngrsll]

cool

[AlainMikli]

here you are

[CASTREX]

So basically 2 step colder Iridiums.


Why would you want colder plugs if you are not FI or advancing ignition timing?

Unless the TOM's gadget could increase the risk for knock at the highest settings...

Did the sales person advise you to use this plugs along with the TOM's unit? Or did you got them just because they were TRD?


Anyway... this is interesting stuff. Some one get more info!!

just what i was thinking.....

[cali yaris]

You wouldn't.

[cali yaris]

or someone willing to pay me the dyno fee

ha, you can afford it, and the chart (and mod list) will get you points at a show.

[kustom play]

You wouldn't.


yea thats what I thought as well

did you just pick these up because they said TRD, be honest.....

[AlainMikli]

yea thats what I thought as well

did you just pick these up because they said TRD, be honest.....

Haha, not because it is TRD. I happaned to sit in one stock Yaris(regular Vitz, not RS) there with just Tom's controller and this plugs, I guess they were promoting this two product. The guy drove me around with +1 and 2 setting, no knock, power climb up very smoothly. Although I didn't see their dyno data, but just my butt dyno. That really convince me to buy and it wasn't super expensive like $600+ anyway.

[kustom play]

werd

i would be curious to see the power increase for this

[PETERPOOP]

dyno!

[AlainMikli]

dyno!

I would love to if it is close to me and someone is paying for it, haha. :bow:

[Sabretooth]

For those who must know...18900 Yen is roughly $210 USD

So if its a noticeable change in power, I bet the HP/$ cost is pretty good. Dyno numbers would help.

[d1nzfe]

the controller only improves timings 0-60mph by split second on a hot afternoon.
so y bother.

:iono: so for both pieces you paid 600 bucks?

[CASTREX]

So you have one of these?


Do you have any more info to add to your statement? How does it work?

[d1nzfe]

we were offered to test out the product by a supplier.
we have used GTEC to measure the timings.
did 3 runs on each settings.
it is suppose to rich en or lean out the AF. by rich'en the AF, we get SLIGHTLY better timings.

[Tamago]

how much for the Denso Iridium plugs?

[kngrsll]

when i changed plugs, i bought NKG iridium Honda S2k plugs, 2 steps colder. i think they were like $8 a piece

Well.... with the exception of force induction... almost every performance mod on the 1.5L engine will make very little improvements. The important thing is if the gadget actually works and actually gives some improvement and per your statement it looks like there were some gains...

Usually it will require quite a few extra hp's to lower 1/4mile times by half a second...

Also, did the test car had any other modifications? Or was it a stock car?

Messing around with the fuel ratio usually will have better results on cars with Free flowing intakes and exhausts.

So if this thingy can give an extra 10-12 hp to a modded car... perhaps it would worth looking at it.

After all... people have paid $400 for an axle back...


Another thing that comes to my mind is that this is actually a "TOM's" gadget... and if they don't know their stuff when it comes to Toyotas... who does?

[kustom play]

with the self learning ecu i would think it would just readjust at the ECU and void out

[CASTREX]

That was my first thought as well.... how ever this gadget is intended for late year Toyotas and Lexus. How would TOM's sold a gadget that would stop working after you drove 50 miles... They should know better than that.

But who knows...

OK we should make a collect to get AlainMikli to the dyno... I'll pay 5 bucks... :bellyroll::bellyroll::bellyroll:

[PETERPOOP]

Alain has mad dough. I don't know why he doesn't want to dyno it. I would think he's curious!

yea but do all new toyotas have learning ECUs? maybe they are different in japan then the us?

maybe they target more sporty cars rather then the economy yaris

but with no dyno to back it up, they we will never know

I would like to see a dyno with the chip pluged in right away, then maybe after 1000 miles with it being untouched to see if the ECU voided it out

Yaris is at the bottom of the Toyota line up.... I don't think our ECU are any more intelligent than a Lexus ECU.

All modern cars have learning ECU's. They've had them for the last 20 years! Yeah the late model Yaris has a picky ECU but all late year Toyotas are the same! Is no rocket science. The ECU uses several inputs to adjust itself. Those inputs are well know. All the pre set values have defined ranges. When people say their ECU learns and goes over their Piggy back is because they are throwing fake values that are beyond the pre set ranges.

Good tuners know this.... TOM's knows this.

This controller most work in some way... the question is how much gains can be obtained on a Modded (I/H/E) Yaris and if those gains are worth the price tag on this thingy.


And yeah, it would be great to see some independent dyno figures!! :headbang:


This is pretty new. I'm sure we will see some more info from the guys in ASIA in the upcoming months.

Meanwhile we can give time to Garm to start sourcing the gadgets... :bellyroll:


PD: Toyota doesn't have any "sporty" cars now a days.

thanks, now still missing $75 bucks:biggrin:

I've spent every penny in Japan already:cry::cry::cry:

plus I need to spend a day for the dyno...

[2bad4u]

US$80 for a dyno test:eyebulge:, we pay in Jamaica JA$1200 or US$12 for two runs or JA$4000 or US$40 for all day.

[cali yaris]

^ that's amazing. I'm moving.

[jouna]

where can i order this??? ill do the dyno i get it 4 free i study @ mech tech college and we have a dynojet

[AlainMikli]

I bought it from Tom's Store in Japan, 18900yen.

If you want I might be able to ask my friend who still in Japan ship it to you, after all shipping & tax, might be around $320 + US shipping...

[kustom play]

i have a dealer in toronto who can order it in

i use to use them when i lived in NY

[marcus]

doesnt this work the same as the blitz controller?? seems like it its just tapped on the air intake rather than gas pedal..

[AlainMikli]

nice, how much do they charge then?

[AlainMikli]

blitz tap to the throttle control sensor and which control the throttle sensitivity, and this one tap to the air flow sensor.

[YarisSedan]

If only these were availble in the US so that members of yarisworld could purchase them. I think there would be a demand. Such as if a vender stock them and sold them. hint hint:thumbup:

[tk-421]

.

[Kioshi]

close to 320 US dollars? You guys do know that in japan items with prices are priced WITH tax or tip included.....LOL So you would only have to worry about shipping and custom charges....not tax. otherwise you are getting ripped off by whomever :P

[crxgames]

I have read some articles on someone making a custom circuit to do the same thing as this on a prius and they were getting good gains...

I really wanna try one of these out now. 2.5" intake, 1zz-fe throttle body, headers, full exhaust, and this could be a pretty nice combo for a daily.

Point me to the articles if you can find them. This would be very easy to do if I had some curves to grab data points from. And, it could be a $50 item.

Very interesting!


Scanning through it I saw this:

So despite trying each of the following, consistent full-load mixtures could not be obtained:

* Intercepting the airflow meter signal with the DFA
* Altering fuel pressure
* Switching the oxy sensors in and out on the basis of throttle position
* Switching the oxy sensors out as fuel pressure was progressively increased
* Switching the oxy sensors out and intercepting the airflow meter signal with the DFA
* Switching the oxy sensors out, increasing fuel pressure and intercepting the airflow meter signal with the DFA
* Intercepting the oxy sensor signals with the DFA
* Disconnecting the oxy sensors at all loads and then setting the mixtures via the DFA working on the airflow meter signal


The solution in this article was to increase fuel pressure, rather than intercepting the airflow meter signals (and 02 sensors). My original thought was that you would need to fool the 02 feedback as well, but with the turbo Prius, even that wasn't consistent.

I'd really like to see some hard data on the Tom's to see if this is worth emulating.

[cfeng]

VIP Auto Salon, a distributor of Tom's in Orange, Ca is offering these for $280 shipped. I'm considering picking one of these up and trying it.

Do a web search and read some of the reviews before you drop the money. It inserts between the MAF and the ECM and fools the ECM into thinking that more air is coming in, so that the ECM will feed more fuel. The problem with it only overriding that side (and not the feedback side via the O2 sensors), is that the ECM adjusts the trim accordingly, so the improvements will only be temporary, unless you routinely clear out the short term data by disconnecting the battery for a couple of minutes.

[eTiMaGo]

or if you put your foot down and the ECU runs open loop? then it could have a permanent effect...

Even so, it's a common misconception that more fuel = more powar, if anything, the stock Yaris runs quite rich at high RPMs, you would possibly see some power improvement from a LEANER mixture...

honestly, I don't feel this thing, look into an apexi SAFC that does more or less the same thing but with adjustability based on throttle position and RPM range. won't be as easily plug and play but I'd see it as much better value for money.

You're on the right track, but your messing with the wrong signal.

What other sensor is inside the MAF sensor?...... Intake air temp. What would the ECU do if it was sucking in -40° air? richen the fuel mixture up permanently until it saw warmer air being drawn in.

All the toms unit does is adjust the resistance of the intake air temp sensor so the signal going to the stock ECU thinks it's in cold weather and adjusts the fuel trim accordingly. I leaned this trick while sitting in on an advanced engine management course when I worked at Toyota Canada.

Whether is messes with the MAF or the IAT, either way, when running closed loop, the ECM will see the effects on the O2 sensor readings and will compensate. My point is that since the system runs primarily closed loop, you have to trick the ECU on both the input and output sides to have a long term effect.


This is from the Toyota T874 course:

The ECM uses the front (S1) A/F or O2 sensor(s) to make corrections to injection duration in order to keep the engine running at a theoretical 14.7:1 (for gasoline) (stoichometric) air/fuel ratio during most engine operating conditions such as idle, cruising, etc.

Feedback from the O2 or A/F sensor (S1) influences short-term fuel trim, which influences long-term fuel trim.

[firemachine69]

Increasing fuel rate does not create more horsepower by itself.

[ostar761]

So does this TOM's Fuel Controller worth a try?

[Parmas]

I don't understand how you can get better power with this controller and especially the plugs

Lets get straight to the plugs, these are almost identical (2 step colder) to my NGK Iridium IK22. I can assure you there is more loss than gains running N/A with these plugs as the combination of spark do not match with the air & fuel mixture.

The controller (in my opinion) is useless unless it is combined with other performance mods like especially a supercharger or turbo. In the case of N/A and few mods or no mods at all, the engine can only loose power if you enrich the mixture or else if you lean it you tend to get a slight power increase putting your engine at risk!


After a bit of driving, wouldn't the O2 sensor tell the ECU to fix the mixture after you adjusted it manually?

That depends how the stock ecu works. With my experience on aftermarket ecus it would be insane to set the AFR adjustment above 2500rpm especially if running forced induction although it would be awesome since then the tuner would be there for nothing since there is the AFR instead haha . It would make more sense that the stock ecu works about the same so putting all in one sentence :

"IF THERE ARE POSSIBLE GAINS USING THIS CONTROLLER THIS MUST BE PAST THE AFR ADJUSTMENT RANGE ON THE STOCK ECU AND SO PROBABLY PAST 2500RPM"

I think this package is designed to be used on those TRD Turbo 1.5L engines and that would really make sense as turbo needs colder plugs and richer mixture which is equal to "You can increase more boost Now" .... of course if the internals withstand it

[pennyracer]

would a colder plug fool the ecu and it run richer and be able to create more power with toms controller i was always told to make more power more in and more out not just one have to have both or does the controller lean the car out and the colder plug account for the extra heat

[pennyracer]

CTScott have you played with satelite antennas yet ? i have a question for you does anyone sale a y adapter so i can run to satelite antennas thinking when one does not pick up the other might loacated in two different spots on the car i sold you your eclispe head unit some time back i hate going under over passes and losing signal thanks again for all the info you put up its very usefull

[Parmas]

would a colder plug fool the ecu and it run richer and be able to create more power with toms controller i was always told to make more power more in and more out not just one have to have both or does the controller lean the car out and the colder plug account for the extra heat

I think you have a wrong idea how air - fuel - spark mixture works in regards to power.

More fuel is not equal to more power unless you have more air coming. That's why on forced induction you need more fuel since the turbo is pushing more air into the engine. The same theory applies to more fuel needs less spark to detonate that's why cold plugs are used.

[pennyracer]

but if its not a turbo like the yaris most have here i wonder what the deal is ?

[Parmas]

but if its not a turbo like the yaris most have here i wonder what the deal is ?

In my opinion these parts are not for stock yaris engines. These are parts designed to match other parts like a turbo setup.

If you are running stock or few mods like an upgraded intake and exhaust this is just waste of money for less power.

[borozinski]

I know I'm bringing this thread back from the dead. But, I was wondering if there has been anyone to test it out on the dyno? I'm kinda guessing that this product never caught on it's not worth anything. Either way just wanna know what the outcome of this was.
