Thread: is my daughterboard shot?

every time i upload a new tune to my calum basic b14 and turn on the car my fans are turning on and its running like super rich 10.3 at idle. im yet to drive or rev the car because i dont think its safe too. Also i have tried to burn multiple chips and i think the ecu is burning them out.

The number 1 slot of the ribbon cable appears to of burnt out. i tried to jump it with another wire but its not helping. any help would be appreciated. thanks

Im going thru the same w my b13, im waiting on my new chips to see if its the daughter board. Got to make sure u put chips in right. I burned my putting them in wrong.

just an update i replaced the broken ribbion wire and now my fuel pump will not kick on. going to try to put the daughterboard in a different ecu

Are you addressing it correctly? You start at 0000 on a B14. Sounds like either a bad bin/chip or board. I have a few problems with different bins that are publicly available.

re-solder the connection, insulate it well, and then re-burn the chips for it. Mine did the same thing for some odd reason when it did it was like it deleted the chips, after I burned new chips it worked fine.

yes the chips are burnt correctly and i have tried multiple bins. all the hex's are correct and i can even save the bin off my chip to the computer to open it in tunepro rt with no problem.




yah im going to get new ribbon wire and rewire it into a different ecu

If you have a burn program try verifying with the buffer of the chip burning software, I just found out I had a bad chip all along and didn't know it, till I programmed it and when verified against it turned out to be bad.

my ecu was burnt out. I am now trying to find some ribbon cable locally which is really hard to find.

maybe it's a calum thing, the guy that bought my old board said his is doing the same thing after re-soldering...

So I'm going thee this now with my calum, what did/are you guy doing for a solution?


In the mean time I'm looking for another ECU,
