Suprab1 Posted June 19, 2010 Share Posted June 19, 2010 Ok lads just realized my supra is hitting boost cut in 4th. Its ok 1st, 2nd & 3rd though. I am now thinking about piggyback or a FCD what do you think? I'm a little worried that with a FCD it will be running lean. Am i right in thinking a FCD fools the ECU into thinking its at 1 bar when you are at 1.2 or what ever? If this is right will it not run lean at 1.2 bar?

JODY T Posted June 19, 2010 Share Posted June 19, 2010 If you have all the BPU Mods the fueling 'should' be fine as the supra ecu runs the car quite rich from standard.. i have a bpu with all mods and its fine at 1.2bar.. If you are worried fit the parts and get it checked on a RR Quote Link to comment Share on other sites More sharing options...
Suprab1 Posted June 19, 2010 Author Share Posted June 19, 2010 Ok thanks for that . I'm also going to a supra meet in a couple of weeks. I was going to put the car on the RR, do you think this would be unsafe if its hitting boost cut? what gear do they test it on the RR?
