Need some help with 750cc injectors

zguynate

I hate to ask to be spoon fed, but I dont really have much time to play with the tune myself. I just switched out from 650cc to 750cc injectors and need a map to drive on to get to the tuner. I just finished wrapping up my fuel system today. I work Monday through Wednesday 2-10 and am leaving around 11pm on Wednesday to go get tuned. I dont have much time to work with lol. Any help is greatly appreciated!! My tuner is a very busy man, so if he is unable to get back to me, I need a back up plan lol.

If no one has a map, I just need to adjust the k value and fuel maps right?

decrease the k by 10% or so it should get you close.

I played around with it a little. I have it good enough to drive. It gets pretty lean between 2000 and 2500 that I'd like to fix. I'm new to this whole tuning thing. I have been reading a lot on the forums and Uprevs website. I appreciate the advice!

the problem is when you reduce the k value you change the bsfc numbers, so all the maps end up referancing the wrong areas of the chart. There is a way to scale the maps to match the change in the kvalue but i would just leave it to your' tuner. Just tweak the k so the car runs rich and drive it to the tuner.
