Rb25det And Aem Fic Timing Advance

[[email protected]]

Im considering putting and aem fic computer on my rb25det with 550 injectors and a precision gt4067 bb turbo. I want to increase response by advancing the ignition timing from the cam angle sensor, as the aem fic only allows you to retard timing.

My plan is to advance base timing to about 20 degrees off boost as the turbo is expected to start spooling around 3800 rmp with full boost around 5000 rpm. Im hoping that the off boost timing will help with response and power. oh and i also have methanol injection!

does anyone see a problem with this plan, or any other suggestion that doesnt include buying a power fc!

runnig a turbo that big, you're out of your mind if you don't get a decent ECU.

Your gonna wanna trust this aem fic computer, It's got the very well being of your motor in it's grasp. Not worth taking the risk man, Do what most people have proven and use a decent fuel/ignition timing ecu, smaller turbo setup. The 25 isn't bad off boost anyway.

the thing is i intend to run about 14 psi on pump gas with methanol, the turbo should be good for about 375 rwhp at that boost level, i plan to purchase an aem ems later when i switch to forged pistons to run more boost, its just not in the budget right now.

my question is in theory, will may plan with regards to advancing timing from the cas and pulling it back from the aem fic work

the methanol injection is also the reason i need to advance the timing to see any benefits from the methanol

the following is a link to info on aem's fic
