I preety much know the answer but would like to know how far off it will be, I have GZ LIM and CJ Fuel rail, I was wondering how far off will be my tune if I were to replace what I have on the car but with the same size injectors, ie, I have 550cc prim and 1300cc secondaries, if I were to instal the GZ LIM and the CJ rail with the same size injectors how far off will be my tune...

Flame suit is on....

Thanks and sorry for the noob question..

First, how aggressive is the tune?? Have you datalog to see if you are running leaner? If not, I don't think you need to worry too much. Most tuners out there are pretty conservative as outside temp and air density changes....

 

Actually, I think its an intelligent question. I'm curious as well. I think the consensus will be that it might not be too far off but you'll need to datalog and analyze results.

 

Chuck from Rotary Extreme Tuned it conservatively at WOT I am between 10.9 to 11.3 AFR's, I have not installed the LIM & Fuel, I plan to install it over the winter though..guess I will just have to do it and see how my AFR's are....

Anymore input, BTW I am running the stock fuel rail and injectors other than the secondaries being bored out to 1300cc by RC Eng...

 

Someone can probably answer this better then me, but, I'll chime in. The GZ LIM should flow a little more then the stock LIM, which means that your car will run a little more lean. Seeing that you are already running on the rich/safe side. I doubt your A/F's will change enough to cause a problem with your motor. However, I would still monitor your A/F's just to verify this.
