Interesting reading!

From my understanding of what has been said already, there are two ways that a scan-tool can deal with this. It will either tackle it in the same manner as IDS & injector numbers 1 2 3 4 will fit into cylinders 1 3 4 2 respectively. Or the scan-tool will do the job in a way that would make sense to someone who doesn’t have specialist knowledge of the subject & injectors 1 2 3 4 will correspond with cylinders 1 2 3 4.

I was wondering how the snap-on MT2500 was going to deal with this task & today I fitted a new injector into a 2002 Mondeo (engine 8) on the VIN plate. The injector was fitted into cylinder number 3. After starting up without entering any configuration codes the engine was quieter than it was with the old injector, but still too noisy. I entered the new code into "cylinder 3" as stated on the scan-tool & it ran quieter for sure.

I did ring the Snap-on help line for some clarification & was told by a helpful Simon that no one else had had any issues. He had heard somewhere about the 1 2 3 4 = 1 3 4 2 scenario, but he didn’t think it applied to Snap-on scanners. I did ask him to look into it & perhaps take a look at this thread. I haven’t heard anything back from him yet.

How do other scan-tools deal with this? Kev have you done any with the ACR?

Cheers all
