I have a fresh build lm7 based engine. I have changed usual parameters for a cam swap but am having issues with starts still and want to know if I am on the right track/ what my next steps are. I have went into 1 bar SD OS and believe I have that all set up correctly. I have also set up an AFR error table and have been adjusting accordingly. The log I am attaching is my first drive in the jeep with a couple of pulls in 4 low since that is where this thing spends its time. The numbers are slightly off from where I thought I was perfect with my discovery of a vacuum leak (now fixed) I also played with my fueling adjustments and have 59 psi across the board. Jeep finally let me rev over 1200 rpms when in drive.
My problems now are that I still have to rest my foot on the gas pedal to get it started for about 5 seconds. If i don't do this, it runs for about 3-5 seconds and shuts down. It does not act like it is going to die when I rev up in neutral and let the rpms drop, but does seem to occasionally want to shut off/lope when in gear.
With my AFR error I took this data and paste special-mult by 50% into my VE table. Do I just keep driving and playing while logging and continuously do this until I get closer? Any help is appreciated and I am happy to atleast gotten to drive the thing and feel some good power.
