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.

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

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


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

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....

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!

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

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

^ 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!

[PETERPOOP]

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