Going Boosted

[FryGuy]

I Plan on going turbo late summer if my finances go as planed. I got some questions for boosted Yaris 1NZFE owners.

This is my first post, take it easy on me please!

I'm looking at the kit on http://www.turbo-kits.com/yaris_turbo_kits.html , looks to have good brand name parts. I know nothing about this company or its reputation. Any comments?

On to business, the install of the kit and intercooler looks easy enough.

What are all then in's and out's of setup for a DIY backyard mechanic.

I know injectors are needed and the AEM F/IC (not included in the kit) as per email with them. What gauges are necessary once setup, I would like to keep stock interior look (no big gauges & wire mess).


Fuel management; I'm wondering how the tuning of the AEM F/IC is done, tools , procedure, etc. I have yet to contact them if they have the maps for the AEM F/IC. I have no problem with computers (being a uber geeky linux user and all) but if i need other expensive (one time use) equipment then maybe its best left to the specialist.

That being said, I don't know of any tune shop in Nova Scotia (or Anywhere in the Maritimes even)!

Any insight into this extensive undertaking is appreciated,
Thank you!

PM crandall....he knows ppl in the maritimes...

a friend of his owns a shop in shediac nb who does custom stuff and he knows the guy in that area w/ a dyno...

Go to the AEM website and search your area for any certified tuners for the FIC.

First and most importantly, I'm glad you want to boost your car. I'd like to see a lot more boosted Yarii out there. After reading my comments you are welcome to PM, email or call me to talk about Yaris performance.

...that turbo kit is partly crap. the log mani is good, the downpipe doesn't fit (hits the subframe). The lines are all the wrong length.

5 of us have now failed to tune the car with the AEM Fi-C. So it's complete bullshit if they are telling you to tune the car with that. Ask for dynos, wiring diagrams and pictures of it installed in a car.

Sorry, just being real here -- I've been working on mine for many months and it's not done yet. Next phase will solve the issues, though.

the only reason the piggy backs don't work, is cuz u guys are afraid of a check engine light... just remove the "learning" curve of the ecu by removing one of the o2 sensors and your good to go (I don't remember which one), thats the way mine was done with the emanage... i doubt your car would pass inspection anyways, so a CEL is no big deal.


as for the gauges, if its tuned right you don't really need any, but just to be sure, I installed a blitz turbo timer dc IV, it is a turbo timer and a boost gauge, just to make sure i didn't overboost. The only other thing to contemplate is a wideband o2 sensor and gauge to be sure your air fuel ratio is right

That turbo manifold doesnt looks that good for flow nor does the angle of the manifold seem to be in the right direction. you can try, but I foresee custom modification to be required.

it's a typical door handle manifold, not much more you can do with it. there's not a lot of room back there for an equal length tubular manifold..

it'll provide plenty of flow (enough to throw a rod) to make the power you'll be able to handle anyway.

[cali yaris]

that mani is making 183 whp at 8psi for me -- seems to work fine. Tamago is right about the room back there limiting design choices, there isn't much.

TurboEcho did an equal length one, but he had to remove the power steering pump to make room.

That's pretty mean and presumptive, IMO. Cheap shot, man.

You obviously aren't aware of the specific issues each of us have had with the AEM Fi-C piggyback. I have no comments to make about other piggybacks, and I'm not lumping them all together.

maybe this would be a good thread to discuss the specific issues you had with the FIC since it's been awhile and there's lots of noobs

[cali yaris]

sure, that's a good idea.

ALL of us either checked with each other and/or AEM to make sure wiring was correct, etc.. AEM was less then responsive. My car was personally driven to AEM where they confirmed that the Fi-C was installed correctly.

For me, the car would not idle for more than a few seconds. over 5500 rpm, the ECU would throw a blinking CEL and limit revs back to under 4000, then revert to an always-on CEL. Yimisport, who was tuning my car, is an AEM-certified tuner.

Richard Holdener had cold-start problems; couldn't keep the car going. Then he blew it up at 4000 rpm on the dyno at 8psi. This was at DynaTek, certainly qualified to build and tune high-performance motors.

Arthur had misfire codes, I believe. He was trying to tune his xB (1.5L, and he built the motor I'll be using next). Arthur is sponsored by AEM for the Horizon Motorsports pro drag cars. He is now using the AEM EMS standalone, making 280 whp and high 12-second 1/4 miles times with the xB (LOL, I gotta say it's really fun to drive that thing).

Carlos had Richard's cold-start problems and I think one other thing. That was "cdyjded" or whatever on this forum; he was developing a promising $2500 turbo kit.

I'm missing one other tuner who tried it. must be getting old.

With all of that said, I am not saying it can't be done -- I am reporting the results that I know about. In my case, it was a costly failed experiment, and I'm done playing with the Fi-C for my project.

which leaves us with this troubling comment by the OP:

I know injectors are needed and the AEM F/IC (not included in the kit) as per email with them.

[Tamago]

here are my tweaks to the issues i've had with missfire codes:

change your injector response time. default is 48ms i think? mine's 8ms
you need to simulate a different water temp while the car is "cold" because of toyota's overly aggressive cold start lean condition. the FIC has a hard time adding fuel to such small percentages coming from the stock ECU.

as far as other things.. hmm... i haven't run into any other codes that have caused serious issues.

[cali yaris]

mine wouldn't idle cold or hot. but as soon as we would hook up the null connectors, she ran great. Still does, 9 months later.

On top of turbo-kits casually saying to go get that piggyback (which I seriously doubt they have tune a Yaris with), the OP posted this:

That being said, I don't know of any tune shop in Nova Scotia (or Anywhere in the Maritimes even)!

I would strongly suggest finding the tuner FIRST, see what they say, what they recommend and what they've done, and work backwards towards management and parts. Just a thought.

I think the SplitSecond fuel controller might be someone's best bet for a simple tune to make some safe power.

So current Fuel management products still don't work right? Or are you just saying that the emanage and AEM F/IC products are not enough?

i would say in full confidence that in the hands of an F/IC genius, the F/IC would work just fine with the yaris.. if the DBW tC can do it, the Yaris should be able to do it too..

my car (previous generation computer, drive by cable,) doesn't run PERFECTLY either. but it is running safely enough for me to rely on it as my daily driver :)

[cali yaris]

are you just saying that the emanage and AEM F/IC products are not enough?

I didn't mention any other product than the AEM Fi-C. I don't have any experience with anything else on the Yaris. My main concern was that a producer of a turbo kit would casually say that's the management to get. I suggested some questions for you to ask them.

Have you found a good tuner yet?

i'll add that i ran a Greddy E-manage and it was even "worse" than the FI/C (less control of the engine) .. the E-manage is just about as useful as a MAF clamp.

[turboyaris]

cali.... i wasn't trying to be mean, maybe i came off wrong. all i was trying to say is i have read numerous threads stating that guys wanna go turbo but won't because their check engine light will be on and i think... your car probably won't pass inspection anyways, the warranty will be voided anyways.... who cares about a CEL


I thought i remembered reading that someone was tuning the FIC with both O2 sensors still installed, in which case it would be impossible for the piggyback to tune the car if the stock ecu is going to be doing whatever it wants anyways.

my post was just a slap in the nuts to tell him if you wanna be fast, you gotta deal with the bs that comes with it
