Re-fitting standard ECU

[freddy_t]

In my cupra I upgraded my ecu for one with a re-map on but kept standard ecu also.

Now looking to put my old ecu back in then fit k03s and all the other goodies required and get a custom map for stock ecu then sell my spare remapped ecu.

However wondering if i need vag-com to do so? when i first had the remapped ecu fitted i tried without vag-com the car wouldnt start (immobiliser obviously) so I re-inserted my original ecu back in to get me to a garage with vag-com.

The car started first time, so just really wondering if i put stock ecu in it'll start straight away as before?? Only i dont have vag-com!

Thanks guys

ull need vagcom i think

cheaper in the long run to just get vagcom...saves bothering with muppets

I dont have a laptop, therefore cannot get it.

I dont want to drive to a garage, swap them over and find out you dont need vag-com.

likewise i dont want to swap them over at home and find out you do need vagcom as if it doesnt swap then i assume neither ecu will work?

hmmm... confusing! lol

Fill your profile in fully with your location, and someone in the area maybe able to help you.

The stock ecu is still programmed to your immo code therefore will still start the car.
