My biggest question is management: the car see's long periods of wot, and quite often banging off the rev limiter to pull through a corner. I'm not interested in chipping my ecu because I don't want to hook up to my computer. I'm getting some 450cc's will a vafc work on my car without vtec? This one? http://saskatoon.kijiji.ca/c-cars-ve...QAdIdZ30541255 I am quite interested in a smc, but I think I read that they don't like wot. I don't quite understand what a vafc does on a turbo car, does it tell the ecu to dump in less fuel with the 450cc's?
Or should I just use a fmu? 12:1? 10:1? I don't want to have fuel system problems after towing 8 hours to go to a race. Any help or advise you guys have would be great. Thanks. heres me (Car #42)http://www.youtube.com/watch?v=3TbCKFLo22M |
Re: Ice race car turbo questions
So what I understand is I should run a chip that pulls out timing under boost, and that will recognize boost in the map sensor? Where do I get such a chip? Would it need to be tuned? The car has no VIN so I can't drive it, also I am not willing to pay for dyno time. And run an FMU with stock injectors? What rate FMU? Should I just save these pretty blue injectors for another project?
Thanks guys you've been alot of help so far. |
Re: Ice race car turbo questions
You would need a chipped ecu and the chip should be tuned specifically for your setup. You can control fuel and timing as well as many other parameters. If you do this you won't need an afc or fmu. Check out the pgmfi.org forum.

Re: Ice race car turbo questions
just run a ob1 chipped ecu with crome as your fuel mangement and burn a chip .very versatile and cheap .

Re: Ice race car turbo questions
If you will pay for my plane ticket to and from I would be glad to tune it for free just to ride in that thing. That looks like a lot of fun. I got the tools.
