Perhaps adjusting the MAF Tables for 2.5 Liter is an option? Possibly "half" the grams per second V8 vs. Four Cylinder?

Perhaps check timing with a timing light that has a "dial indicator" for...

I'm wondering if maybe the '0411 Four Cylinder Coil-On-Plug Ignition System will work without a Cam Position Sensor . . . Post #3 in this tread.

Congratulations :wtg:

The .cal was converted to .bin using flash - then - read as a .bin method.

Can you work with a .cal file?

will need at least one correct MEMCAL for the set up. - - - Yes - - - V8 MEMCAL from a 16197427 would be a good choice, likely a V8 MEMCAL from a 16168625, 16196395, or 16156930 will also work.

The G1 adapter and SST 27SF512 chip can be used in the 16197427.

The '165 MEMCAL WILL NOT work in a 16197427.

Using a 5.7 liter .bin file $OE or $31 (4L80E definitions) will work.

There are differences between V6 and V8 MEMCALS, so using a V8 MEMCAL is good plan. :thumbsup:

Documents converted to .pdf.

Original documents were MS Word and MS Excel.

I have experience on a similar project, a MPFI modified 16197427 7.4 liter / 4L80E. Based on the awesome success of that project, I recommend using the 16197427 for your 383 / 4L80E.

Would I be correct in thinking your using a MAF 1227165 ECM?

I'm wondering if you are using an aftermarket 4L80E controller?
