Ok guys, I just got my PP2 in today with a couple of AT29C256 EEPROM chips and Craig Moates adapter. I used TunerPro to change injectors flow rate only using an Authentic bin for a 92 Z28 305 5 speed. I'm getting error code 41 cylinder select error faulty memcal when the car runs for a few seconds. What am I doing wrong?

 

be sure your ECU file is the correct file and that the items you changed are defined correctly (and not stomping all over another item, such as the "Cylinder Select" byte). =)

 

I'm a dumb a$$. I found the problem. The factory memcal was inserted backwards in the Moates adapter. I reinserted it correctly and this car is a friggin' monster! I've been initiated to the DIY PROM board

 

Welcome to the club.

Just wait til ya do it a second time, and then go, dugh..........

 

Hopefully that won't happen. I'm a pretty good first time learner. One thing that i did find unusual is that the car started and that tach started going haywire and the engine ran stupid rich and then the engine light came on. If the memcal was installed backwards, how in the heck did this car start? The limp home side of the memcal was completely disconnected on the adapter.
