Re: Adjust injector pulse for coolant temp

Not sure if it's correct or not but I changed the calc from x/1.28 to x/2.56 & seems to make a bit more sense?

But still doesn't fix my below 20 degree fuel issue with deka's is there an actual injector modifier rather than afr fudging?

Just as an example as to what is happening attached is the log of a cool/warm start where up to 7.598 seconds the wideband is close enough to the commanded but after that it has a lean spike & if it was cooler it would have stalled but because it had been previously started it didn't.

I've also attached the ADX used to log/play it & the bin file & xdf used just incase people can see the reason as to why it's out with what I have adjusted.

It has a cooler & throws the AE & DE out too much if anabled so thats why there adjusted out but I have also adjusted some of the AE & DE tables to try & tune with it but was no good so reversed the enable/disable scalars anyway just thought i'd mention it if anyone thinks that could throw out the after crank fuel issue.

Injector change for start up coolant temp

Post by VX L67 Getrag »

Has anyone got any tips on changing the injector settings for coolant temp, or is it best to fudge the AFR tables as mentioned?
