End of Injector Pulse.
Posted: Sun Jul 07, 2019 9:31 pm
Been away from home for some time now, so using alone time to familiarize myself with a parameter within the ls1 tunes that I find little mention of here or other forums, plus the info I've found isn't definitive.
The end of injection timing in EFILive is referenced in mS, a total of 8, and in HP tuners defined as reference periods, again in a total count of 8, leading me to think that each single unit represents 90 degrees of crank timing.
Why EFILive reference it in time (mS) makes no sense that I can rationalize as the differing crank speed means differing timing settings.
Probably spent the best part of 2 months researching this feature, one that in my opinion should be altered when aftermarket cams are used, and prior to making any other alterations in the tune, however I don't want to tune altered motors without having this option available in TunerPro.
Has anyone else here written an xdf with this feature added that is willing to share, if not, i'll keep chipping away at it til I work it out myself I guess.
My first effort at creating the entry for the 12202088 and 12225074 has resulted in editing the right area, though I'm not yet 100% sure that the math equation I've entered into the xdf is a correct representation of a feasible setting, though the EFILive example results in the correct change according to EFILive when opened with the program after editing with TunerPro.
Would love to have the tools to jack into the injector circuit and measure the differing end of timing figures myself with regards to the differing temperatures.
I have an xdf that equates the figures the same as EFILive, though I've dropped it in favour of referencing the final figures in crank degree's as in this pic below.
Thanks lads.
