Hi

The Immo On/Off is a program pice inside the Eprom (27c512), on GTV with NO immo chip inside The ECU.

I don“t have ECUs for GTV 2,0 V6 or 164 2,0 V6.

Immo is a problem on older Cars. BUT some spend a lot of time solving the problem.(eks Rover 820 with mems ECU) you but a other code in the immo chip inside the ECU.

I had have a problem with a Fiat Baretta with Hitachi ECU. Engie will not start when the weather was hot. Immo will not work.

I found a code to put in the immo chip inside the ECU, and dismount the immo boks , the engine starts now all the time.
