Hey guys,
With the help of some of you and some searching I have got my fuel and timing base maps complete. Thank you.
Can I get a couple guys to take a look at my logs and my tune file? Its running so well and the ltft are +/- 5 percent. I am curious what you more experienced guys would take as a next step. I finally received my wideband and will be installing it tonight/tomorrow which should help with any next steps.
What I have done so far:
Truck is in "tune mode" (MAF disabled, torque management disabled, PE Disabled, high octane map same as low octane map etc)
I have been tuning the VE table.
Startup and idle are damn near perfect at any temperature now while maintaining +/- 5% fuel trims
I have adjusted base timing table to ensure there is no knock/retard, as well as modified the "[ECM] 12636 - PE/COT Spark Advance Correction Mult vs. Fuel Composition: The multiplier is used to modify the PE/COT Spark and Flex Fuel Spark in relation to fuel composition" to be what the timing was when i was making dyno pulls (subject to change).
So how does it all look? What changes should I make? What would your next step be?
Thanks a bunch guys.
Rich
