MS-I code and daughter card.
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)
Re: MS-I code and daughter card.
I forgot to ask, after I down load the updated code with easy therm it say's "Don't forget to copy the .inc files to the mega tune directory". I'm not sure what file to copy and where to copy it to. Phil
Re: MS-I code and daughter card.
Today I took the top off of my MS-I and the daughter card was touching the top of the processor. The processor has just a little conductivity.I checked the flyback daughter card for power and ground and checked the other inputs and outputs and I think they where ok. I left the top off and ran my engine for a while and I can't take my pwm current limit any lower than 60. I set it at around 64 and it will start there and run. Does anyone have any way for me to see if the flyback daughter card is working? I'm still having troubles with megatune and had to use tuner studio again today. Any idea's on that one? Phil
