Motronic problems with 3.2
Hi,
I have 1989 carrera 3.2 Japan (USA) 930/25 engine . I made complete overhaul to engine last winter and also changed Euro/Row pistons (10:3) .
I tested and run engine with my old motronic 911.618.111.20 & 28pin wong chip to USA spec engine. Everything was fine and engine worked quite ok, however today i had from i friend of mine a Euro model motronic 911.618.111.18 & 24pin chip to euro spec engine (no lambda).
Now i have problem, at first idle was bad, i tried to fix it by adjusting. I had it settle but when i throttle car and release engine almost die and idle is wander a while.
Well i also made quick drive and test.. but it works poorly.
What could be a problem, is there something with the lambda or what ? Do i somehow must disable lamda even when this older euro motronic box is not lambda compatible.
Thank you advance.
