Tell me what you guys think of these pulse widths...remeber these are with race gas, with regular 91 octane they increase by about 2-4ms...
RPM MS
3500 30
4000 29
4500 28
5000 32
5500 30
6000 28
6500 27
6900 24
Stock injectors running with a 4bar fuel pressure regulator...

Re: My Injector Pulse Widths on Race Gas... (smd3)

it's possible that the ecu programming will add more fuel to combat detonation.
High octane allows you to safely run leaner as well. More timing + leaner = gobs more power.

Re: My Injector Pulse Widths on Race Gas... ([email protected])

Without the 4bar fpr the pulse widths increase even more. Thanks for the graph andy, thats kinda what I was looking for to see where everyone elses pulse widths are at.
I'm planning on larger injectors, which will require a new file but out of curiousity how much will the ecu compensate for (+/- 10% or so) It seems to compensate for the 4bar fpr as well as the race gas?
