I am working on my first hemi and could use some help.
It started as a 6.1 from an SRT8 which was bored and stroked to 426ci. It has been swapped in to an off road 2002 Jeep Grand Cherokee with long travel suspension and uses a 2005 Ram ECU and base tune (attached) from Hotwire who also did the wiring harness integration.
Only modification to the tune from HW I have made is injector tables as it has Trackhawk injectors installed. I found a couple stock Trackhawk tunes in the repository (one attached) to compare the injector flow info against each other to ensure they did not differ from one another and reconfigured the tune from Hotwire with that info (again attached). I will say that the TH injector table does have one additional cell which I omitted (0.0074/0.8000 on INJPW vs. Fuel Mass table and 0.8000/.0074 on the Fuel Mass vs. INJPW table).
Once cranking vehicle will fire, but wide band goes rich (10.0afr) and it stalls. If I crank more, I feel it loads up and doesn't want to fire.
My question here is what is the best approach to reduce cranking fuel?
From there I assume making changes to the VE table(s) like you would for a mafless LS1 0411 ECU to get running idle AFR in line?
Any other thoughts, suggestions would be great.
Thanks in advance!
