Hello, i fear you have to set rpm manualy by a choke.
I opened AHWZ.bin ( you can find it here on the forum) with the $42.xdf
Wenn looking to scalars I found that there is no acceleration for A/C.
Off course can you give the eprom to s.b. here on the forum to change this setting!
I have bin AMUS for my 7747 ECM, it has IAC RPM added to Desired Idle with A/C on in Scalars, read the comment for setting this.Hello, i fear you have to set rpm manualy by a choke.

" S.B.? is that a member on the forum? "
a lot of them : somebody . lol
Ok, well it took a little while, but I was able to clean up and remove a lot of the old wiring in the engine compartment that had nothing to do engine operation. I installed the heated O2 Sensor and most of the sensors that weren't attached.
I was able to take the rig for a test drive and data logged the journey. Hitting max speed (25mph) the fastest the rig would ever travel. 5 mph is average.
Dave W, thank you for the original bits of info, it looks like shes running closed loop now and not running as rich! I'm still having some low end power issues, which I believe is the transmission not shifting down as she sounds like it's bogging down just to get up short inclines.
3-16-2018a is from first firing up the rig and heading up the driveway
3-16-2019b is the full drive session.
DaveW do you think you can glance these over and let me know your thoughts?

The chip does not have the Spark Advance (SA) *Hack*or Injector Base Pulse Width (PWM) *Hack* applied. SA & PWM is very useful data! I recommend installing a custom chip with the SA & BPW *HACKS*.
Knock Counts are excessively high! I'm wondering about the Knock Sensor, ESC Module, and related wiring. Not knowing SA is limiting the understanding of Knock Counts.
The BLM's are sometimes ZERO, which I don't think I've ever seen that before. Not knowing BPW is limiting the understanding of the ZERO BLM's.
The data log show MPH, sometimes 100 MPH? I wonder about the VSS wiring?

Hey Dave, absolutely appreciate your input and help!! Thank you.
I'm going to do some research on the forums and read up on the SA *Hack* and the PWM *Hack* this is new to me. As per your recommendation, where would I find and how much would I be looking to spend on a custom chip?
I'm going to head back out to the shop and take a look at the knock sensor, esc module wiring.
I purchased and installed the 2PRS Speed sensor from JTS and wired it directly to the VSS sensor wire to the ECU.
I don't have the Automatic P / N wired up, I assume that's why it reads that it's always in drive. Would this be an issue to leave disconnected?
