Alright guys quick question..I know you can run a non-vtec d15 on a p28 ecu and it will work, but throw a code for vtec since it is not wired so here is my question....

my friend had a boosted z6 with a t25 on it, he had it tuned and ended up parting the car out..now I can pick up the ecu cheap, so would this work on my d15b7 if I ran his set up..same injectors, fuel pump t25 ect and have no issues with my b7? would it run rich?

I wonder because I would think the p28 would have a little different fuel graph since a z6 has a bigger IM and TB so it sucks more air..but I could just be an idiot here..

Thanks for the help

 

That a good question id like to know the same thing.. I have a d15b8 and ima be doing a d16y7 head and i too will be using a P28 ecu need to know if it will run rich.. Ima be using after market intake manifold BIGGER.. So i need to know what needs done and is there any way 2 get rid of the CEL?


BUMP

 

im running a p28 in my d15b7, don't think its running rich i get about the same gas mileage as the po6 i had before

 

get it retuned, dont go off the old one alot changes with a diff engine
