78CJ with sbc and not happy performance

[Dlxman]

Dear All, I am looking for assistance getting my jeep back to running like it should be. I have been reviewing posts upon posts looking for "the" answer. I now have Tunerpro RT, the moates ALDL cable combo, $42 XDF & ADS files from Tunerpro. My problem is finding the correct BIN file for my set up. Looking at the gearhead index under *7747, I am overwhelmed.
My set up is: 70's chevy 350 2 bolt, stock pistons 030 over, 195 heads, cam of 69 vette, Howell TBI, 7747 OBDI ECM, no EGR, no Cat.
Tech support told me to treat it like a 1990 chevy pick up 5.7L. It ran great, suddenly since May this year it is stumbling under load, and stalling occasionally no error codes. Diagnosed by wallet for all sensors, pumps, filters. Fuel pressure (https://www.walmart.com/search/?query=fuel%20pressure) is good etc.
I desire to scan log while running to see if I go to closed loop, and what the other settings are.
Thank you for your time

so your problem is finding the correct bin, to help diagnose a newfound running issue? you don't need a bin for that.

if it was running fine before, and now isn't, all you need is the correct ADX to do some datalogging to help find the problem.

bins are for tuning (modifying your calibration) and you definitely shouldn't be touching that until the problem is found.

tunerpro will do all the datalogging you want without a bin or xdf file loaded

Hi Steveo, I was able to log the data. It looks like I have some issues with the IAC and real high counts. I idled for a while, then took it out for a run. WOT while driving on and off, then running through the gears WOT. Can you or someone help with interperating the data log file. Did I capture enough data?
