Sounds like an easy question, just start it up,stay in open loop and record.
Problem is(and im just being anal) it is a fresh...never turned over engine. It's not a G8 but my son's 2003 2500HD that was an 8.1 Litre that is now 9.3. The last thing i want to do is crank and tune.....crank and tune...etc since i am seating my rings. My biggest concern would be to get it idling without washing out the cylinders, then a MAF adjustment while it's idling. I'm guessing dividing 496 into 572 will get me close on the MAF scale which adds 1.15. I would put that above idle 3000Hz and up. The cam is a little bigger and more duration but everything else for now is stock. If this is feasible, my next concern would be my idle, how should i approach this.
I'm not used to tuning an older ECM with VE either and would like someone to double check to see if i have it disabled. I do have the EGR master disabled.Also what i would need to change in order to go open loop and do the MAF tune with this ECM.
My biggest concern is the IDLE, getting somewhat close with the MAF initially so i can fine tune it after it warms up and i take it out under load/unload to seat the rings
Stock heads,intake, mild cam,cai
This will be done watching the fuel trims since it has no wideband...yet.
Does anybody know anyone who had tuned one??
Thanks.
