I've just tried to run a different '7747 ecm that I've adapted to take an Ostrich/eeprom (with Moates G2 adapter). I had to use the asdz .bin from tunercat as I couldn't read my Hypertech chip to copy (it was unfeasable data!). I uploaded it to the Ostrich, plugged it all together and fired the truck up. Well, it was like starting a carbed motor on full choke when the motor is already hot! It chugged and loaped, getting worse as it warmed. Question is, could this be due to the .bin being wrong (the one they supply is for an '87 truck, none others available) or have I messed up the installation of the G2 adapter/ecm? Would it run at all if I've screwed up this installation?

Yes, a K5 in England. I've had 2 '78's and this '91. I've also got a 2005 Ram Daytona. You'd be surprised at the amount of American cars and trucks over here. The hotrod and muscle car scene is really big.....even at nearly $8.00 a gallon!
Right, well...I'm very embarressed to say that like a typical male I didn't read the instructions properly first and actually put the Ostrich conector in wrong!
Anyway, we went out today and did some good data logging and emulating. I've manged to get the BLMs to around 128 under most circumstances by messing with the VE1 table and the PE table. It runs much stronger now. I still may mess with some timing.


I can't understand why at idle my BLMs are rich at around 125 steady and the INTs are steady at 128-129. Shouldn't the BLMs 'catch up' with the INTs?

No...BLM is a long term adjustment stored in the ECM memory.
Go back and read the tuning articles by ECM stickies.
The BLM etc is common to all of them so you may need to read about a different ecm.
