    Yes, those files are a huge help for the software and hardware mods. I updated the fuel tables based off the AUJP bin from a 1227730 ECM, similar car and TPI engine. Waiting on new oil as the stuff...

    UPDATE: Got the engine to run yesterday afternoon, although it is idling like garbage. RPM's surging between 700-1000 and its running pig rich. I lowered the Injector Offset vs. Battery Voltage to...

    Yes, I think I completed every step to run multi port fuel injection on the 7427. There are several flags, constants and a couple tables to change. Plus, I'm running Bosch III injectors.

    Thanks! Last night I was able to shoot the timing light down the front of the engine, while turning it over. No sign of the balancer mark, so I'll be pulling off the cap and figuring out what is...

    I

    Just finished installing my new engine with a TPI setup in my 85 Trans Am. Using the '7427 as I'm familiar with it from installing a TBI system in my 78 Vette.

    The 7427 has been modified with the...

    Added the pause command (thank you for the screenshots, those REALLY helped!) and the noise was greatly reduced. Log much cleaner. On first drive, was running poorly - bogging down and stumbling...

    Looks like something went off the rails in the past twelve months. I found a log from almost exactly a year ago (July 12, 2020) where I was checking on the function of the EGR as it might relate to...

    Thanks for spotting the Closed Loop Idle flag. I will check that out and experiment.

    You are right on the noise in the signal. I've seen that before on previous tunes and logs. My thoughts were...

    Finally was able to get in the car long enough to record a log while driving. Hopefully I'm attaching it correctly? This is with a new oxygen sensor (Bosch 13077). I'm concerned that while holding...

    Agreed. I was reading back thru the pdf manual from years ago, oxygen sensor cross counts, or something to that effect. Will fire up the car and check it out. Thanks!

    I should also add that the coolant temperature reading in TunerPro is spot on, around 200 degrees when at operating temp. Also, there is no check engine light being lit.

    Thanks! Checking thru RockAuto, looks like a KS6 from Standard would be a match then.

    Using a TPI setup versus the original TBI wouldn't make a difference, correct?

    I had lots of trouble with spiking ignition during AE. I think it was because I set the ignition to 12* BTDC, even though I changed the parameters in TunerPro. When I returned it to 0 (as the factory...
