Question on Fuelling


Vaughany

Recommended Posts

Vaughany, you are running a similar set up to me (turbo) but i still have 550's (264 cams) Trying to map at the mo, but am getting some strange numbers, what fuel pressure should I be using? Was 32psi but maxing out the duty cycle at 1.3 bar, now increased to 42psi and seeing 10.2 afr at 1.5 bar but 8s in transition. Think i need an e-manage, oh and Ian C.......

Hello mate, I cant answer any of your questions at the moment as my car is in at JPS getting all the work done now. However I understand that the Emanage is a bit more controllable than your current setup so this maybe the answer.

 

Please dont quote me on this as I am definitely no expert but I think you could go with bigger injectors I think I would be right when I say this would allow you to turn down your fuel pressure abit so you dont run to rich when you dont need it and then use your fuel computer to increase the fuelling when the boost increases. Bigger Injectors will also prepare you for the next stage when you decide to run more power again.

 

Like I said mate, I am no expert and hopefully someone with more knowledge than me will be able to answer this better.
