Hi,

I have a strange problem with my 8v integrale. I have the car completely restored in the last 6 years and now in May when I first started it up I hit a bump.

The car doensn't run on the standard 8V ECU. This was checked with a second OE ECU. Both are working in a friends 8V integrale as they should.

But at the same time the car runs normally on a Dedra 8V turbo ECU and on a 8V integrale KAT ECU. It even works on a 1.6 HF Turbo ECU.

Not only it runs I have driven it for over 900km on the Dedra ECU but on the OE ECU it hardly starts then struggles and is totally unresponsive to throttle blips.

Any ideas?
