Perhaps some youtube videos for TunerPro RT will help understand the tuning process? https://www.youtube.com/results?sear...ry=TunerPro+RT

Ok, so the engine has been installed and is running decent with egr disabled, but its running really rich and im not sure what I need to look at to correct it in the tune ….. any help would be appreciated. It is also kinda rough idling, don't know if its related to the rich condition or? and has decent stumble when I try to get on it. HELP

Changing the injector flow is a course tune option.
Increasing injector from (from 61 lbs/hr to 63 lbs/hr) makes everything LEAN, because the PCM thinks the injectors are flowing more than they actually are and reduces injector BASE Pulse Width.

Decreasing the injector flow (from 61 lbs/hr to 59 lbs/hr) makes everything RICH, because the PCM thinks the injectors are flowing less fuel than they actually are and increases injector BASE Pulse Width.

The BEST tool for tuning fuel (RICH or LEAN) is a Wide Band Oxygen Sensor (WBO2)?

Sorry to jump in on this thread, I'm curious, where do you set the injector flow in the bin file?

Most TBI .bin files 1993 to 1995 have the injector flow parameter in lbs/hr. Most TBI .bin files before 1993 have a Base Pulse Width (BPW) as the injector flow.

I thought I read somewhere that if u disable egr in bin that u will also need to adjust spark? what where and how? What causes hesitation when throttling hard from a stop and is there something in bin file that I can adjust to fix this?

if I can figure out how to post my latest bin would someone tell me if it looks alright the truck is running better but I am still unsure of what I'm doing and don't want to screw up engine.
