I would not adjust or play around with ANYTHING until you've given it some actual driving time to learn.
Just double check ALL "needed" parameters that you have ser and entered, then once fully warm, set IAC with the idle screw, and drive it.
It won't start to learn until it's at 160 degrees, as measured by the Holley supplied coolant temp sensor...I had to change mine to an aftermarket one since mine read upwards of 20 degrees lower than actual....and since it's gotten much colder, mine was reading in the 150's so not learning at all.
I've also 100% POSITIVELY found that mine has an issue regarding running Timing Control.
I had done everything that the Holley manual said to do, and done the other things that were never even mentioned and still have a random, loss of power, which caused an intermittent stalling with no pattern to it whatsoever....
Since the Sniper datalogs are inaccessible until they finally release their software, there's nothing to check.
Distributor was locked out.
Holley required tuning parameter changes done.
Distributor/Computer Timing matched at all RPMs.
Rotor was phased perfectly
Reference Angle set 10 degrees above highest timing commanded
Inductive Delay set to allow timing match and steady reading
Timing parameters set as close as possible to previous mechanical/vacuum settings that have been proven over the last few years.
Idle was smoother, but extended idling or light throttle cruise, my car would randomly die, IAC would go full open, and act as if key was shut off, and engine restarted...
After this happening AGAIN about 10 times yesterday...I decided to AGAIN switch the EFI back to NON Timing Control, and AGAIN the car runs 100% fine like that, with no stalling whatsoever...I removed distributor, reinstalled the weights, springs, 11 degree advance bushing, and vacuum can. Set total timing at 44 degrees, and good to go again...Very pissed about this....
Anyway, hooked up sans Timing Control, the efi works, and car runs, great. What sucks is I had planned to use the Holley to control ALL nitrous functions, including timing retard, and now that's not going to be an option, evidently...
