the ECM is off my 'fuse' box, connected to starter solenoid connected to battery, the alt is connected at the solenoid. it should see 'full' power all the time. but is does see voltage drop at idle. 12.1v to 14.1v is the full range I'm working with but mostly 13.1 to 14.1. it could also be the battery, mustang battery 'died' so I am using my older bronco battery... I'll recharge the other and see if that has any affect.
thanks Robert, as far as 'learning' no, none, it's very consistant, but on adjusting it's awesome, places/times where my carb would stall the ECM keep the engine running and it's VERY nice. SUCH A RELIEF!!! some cool things to know... city mpg is 17.5 with bad/high warm-up idle (2700rpm) and 23mpg freeway with poor high speed acceleration. I'm sure these will be imporved but they are the same as my 2bbl carb according to my records. t-stat temp ~210-230 and I NEVER ping (heat will help mpg, but I previously saw water temp from rear of head). so the ECM has some very nice benefits. absoutely worth it, and it's just going to get better.
