Thanks for this info. I looked through my parameters and I don't see anything with lists, or a VE table for off throttle. I only have VE as a %. Do I need to be hooked up to the truck to see that info? My distributor is an IH holley, with a duraspark conversion. Basically, a small cap HEI... I definitely want the ECM to control timing...Originally Posted by dave w
TunerPro RT can provide an enormous about of information, see screenshots below.
Many years ago, I experienced frustrations with a fuel only aftermarket TBI system on an IH 304 Scout. I installed a DUI HEI distributor and the Scout came to life when the 1227747 was controlling spark. TunerPro RT "Recorded" or data logged the Spark Advance (Hack Required) and Fuel BLM's (Rich / Lean).
Data = Performance. . . the absence of data = frustration
