MS-I code and daughter card.
Posted: Sat Nov 05, 2011 4:49 pm
I have an MS-I and V2.2 board. It's running a small block chevy. I'm using the GM tbi unit. I just got it put together and started. I burned up the flyback curciut on the board so I replaced u7, q2 and q7. I then installed the flyback daughter card. I updated my code with easy therm to v3 and it seemed to function ok. But if I tryed to fetch the code back from the ms computer it would be totaly wrong. I would change it and send it back to the ms computer and it would still come back wrong and I couldn't get it to start. Then I tried to configure it with tuner studio and I could get it to run and do ok. But when I start it I have to set my PWM current limit to 75 and as soon as I get it running I have to back it down to around 40, but it won't start at 40 just 75. It seems to me that my flyback card is working but it is not shutting off at start like it should. Is it code? Is it in the flyback card? Am I down loading the right code? I'm not for sure how to tell wich one I'm ending up with. Please ask me any questions that might help you help me figure everything out. Don't laugh at me to hard, some is ok, if it is an easy problem to fix. Thanks Phil (newbie)
