Thread: bad b13 calum basic

so my fuel economy has been crap, finally get around to plugging in a consult cable and I have no o2 reading and i can't turn the fans on.

toss in a stock ecu and all is well.

is this likely to be the daughter board, or the ecu?

how much of a pain is it to remove the daughter board and reinstall it into another ecu?

Thanks.

it could also be the chips.

everything I've read so far says bad chips make the fans stay on and give a CEL but maybe.

My old calum went bad..an oem chip on the main board had corroded and mad fans on,with key in on position and cel too...car ran like shit, it would rev up but realllly rich....the chips ended up being ok but main ecu board went bad

I suggest a nismotronic ecu...thats what I bout after my calum failed,johns a cool dude hell hook ya up...and whatever chips you are using now,will work with the new ecu

I have to look up the info but last time I did a board saP it eS about $50.
