My check engine is on.
Ive tried every thing, i shorted the 2 spots on the plugs nothing happens... When i plug my data scan cable it wont connect to the ecu ?? My car runs like shit and i cant get the fault code... What could cause this ...

red ight on in ecu when car is running == knackered ecu or knackered crank angle sensor == safe mode 2k limit and fixed maf volt == running like a tractor

try a different com port on datascan, turn off auto find, and search for ecu manually, should find it that way if you haven it set to correct com port.

thats interesting. is it a plms daughterboard (nistune)?
It might seem like a semantic point, but although Nistune use PLMS boards an PLMS board doesn't mean it's Nistune.

I've got a feeling the Nistune guys used to work at PLMS because I'm sure there is some kind of link, but I can't find where I read that now.

Redzone garage, it came in the car when importing from japan. I think when i last burnet the chips, ive put them back in the wrong side on the chip socket so it fried the smaller board chips or my chips. Ive ordered a plms.
