Hi there just wondering is it going to work if i put a series 2 blue chip in my vr series one and make my five hdd auto work properly insted of service light comin on at 80 kmh and above because the series 1 ecu does not reconise it and cant change into 4th properly also its the ecu that came out the car the auto did any ideas?

i had that problem with a vs wagon. it turned out inside the tranny there is a bypass of some kind, it didnt work and would not go into 4th. tranny repairer could test and would know by readings

it can be done providing the wireing loom is the same as the one it came out of just letting every one know btw it can be the hole ecu not just the chip inside
