Hacking the ECU on 155Q4

Is there anyone here who knows if there is any attempts to make a computer program which reads on-board diagnostics on the Weber-Marelli ECU on the 155Q4.

If not, anybody interested in starting a project to do so?

Apperantly, there are som projects going on for the Fiat Coupes Turbos which has similar ECU“s, anybody interested to join?

I doubt I could be any help, I would be interested in the outcome.

If it can be done to a 16v Fiat Coupe then it would be a very similar job to a Q4

Im certain the grale's have had this done many times
