Re: Programmable HEI
Yes, I verified a few steps and looked like it was tracking well

Re: Programmable HEI
Update: Still playing with it. It is everything claimed and works great. I've been able to smooth and raise the idle speed only when in gear by adding timing to the lowest rpm settings. so far works great. Need to dial in my new carb also but the other day with about 80% freeway and 20% in town driving, not really taking it easy I managed 15 MPG.

Tdangle, how are you liking this after a few months? Any issue with the bluetooth connection? My son is having similar idle/transfer slot issues you had with the 454 we installed in his camaro. I was going to do the set screw thing to his HEI to limit his mechanical to about 10 but I like the idea of the kill switch and starting retard feature with your distributor. But I have always been hesitant to use things like ignition boxes because of adding one more possible electronic failure point. Everything is a tradeoff I guess. |

Re: Programmable HEI
So far very happy with the unit. Fun to watch the timing in real time. I’ve been making some small adjustments to cruise timing to help mileage while on the hwy. for the most part just driving it.
