FINALLLlYYYY after months of waiting im getting a maptun stage 2 ECU for my 99 viggen. Ill keep this updated with pics of it and what i think of it once i get it.
if you were able to start the car with the maptun ecu at least once, then it a bit less likely to be secuirty. if the TWICE/immobiliser code was not there/not right it would never have started at all. (don't ask me how i know this) :roll:Boxerchip said:I had other air flow mods... nothing that would do this... but basically it just wont turn over when this ECU is in then the CEL comes on. looks like a security problem... but we are not sure exactly what it is....
