data log of injector shut off on accelleration issue

and if you are swapping code bases from say 6E to E6 or any other for that matter you need to disconnect battery

It's running timing looks good, PE works, AE works all is good now getting the AFR right and it's all god. Thanks everyone for all the help really appreciate it.

Well I think I found the issue with the engine shutting off while accelerating. The VATS Frequency Test fails at the exact same time the engine quits every time. Must be the wire running down the steering column issue common to VATS. I do have another question. If you can look at my log between 5:51:815 to 5:54:431 on heavy acceleration 12.5 AFR is commanded but O2 shows lean. DC% is only 50% so not sure why the commanded and result does not demand more Duty Cycle?? Any Ideas? I set the injector settings to 65LB like Holley calls for on the 670 TBI. And changed the engine size to reflect a 383ci. Thanks for looking at it.

Your running Open Loop so Desired AFR is going to change from whatever is commanded in "Open Loop AFR vs. Temperature vs. Vacuum" table.

If you were Closed Loop the AFR would be 14.7 or whatever "Stoichiometric AFR" is set to.

There's been an issue with Injector Duty Cycle math for quite some time we found awhile back. So your hitting 50% and with wrong math it's 100%! Your out of fuel! Need to change the conversion in your ADX file for Injector Duty Cycle to:
TBI IDC (%) = [4 * IPW (ms) * RPM]/1200 (mistake was 2 and needs to be 4 so your only reading half!)
old
( X * Y / 60000 * 100 )

New conversion for Injector Duty Cycle:
(X*4*Y)/1200
