Startup Tune for the Project Truck
I am going to attempt to make my own startup tune for the truck(baby steps), I am not very tuner savvy and basically need to be hit over the head in the simplest terms.
First Question, is "Fuel Control" the parent location where I'll go to adjust for the larger injectors? which tables do I need to modify? http://img.photobucket.com/albums/v6...uelcontrol.jpg |
Yep, Flow Rate vs KPA will need to be set for your new injectors. Also probable need to lower your Min Injector Pulse to so it will idle.

Yep :)

and I set this to some value less than whats listed below so the larger injectors don't dump to much fuel into the motor?

Yep again :) Mostly, thats an idle issue, bigger injectors can't squirt small enough amount in that specific amount of time to keep the idle AFR in check.

which brings me to my next question, how many total tables effect engine idle? or more specifically, what other tables should I be looking to modify to satisfy my fueling needs using the larger injectors? or is that it?
Also once its running you will want to modify your RAF table for your new airflow values. |

With my 60's that min pulse table was too low, they would missfire at idle and it ran lean. My min pulse is in the 1.0 range..
