Title: Manual ecu in auto car...
Post by: Doctor Gollum on 24 July 2017, 18:59:47
Don't recall it being a particular issue, but just to double check...

Will a manual ecu function normally in an auto car?

Auto ones work in manual cars, just brings the spanner light on. Imagine its the same vice versa.

This is my hunch too.

If the auto has been converted to manual then the gearbox ecu must still be connected (something to do with the inhibitor switch)

But the auto engine ecu should be ok with a manual box

The Map is slightly different, on a 2.6 Auto/Manualyour probably get away with it without noticing much difference. On a 3.2 more noticeable, especially if you put an 3.2 Auto ECU into a 3.2 Manual Car.

On 3.0 NDBW just use the original Eprom Chip in the new ECU. Never played with a 2.5.

All of the above shouldn't throw any Fault lights, although Ive seen this happen when putting cheapo 3.0 'so called' Performance Eproms on a 3.0.

If I leave the battery disconnected for some time, the ECU seems to reset and it shows 4 cylinder/manual until I turn the ignition and it suddenly recognizes it as V6, then touch the shifter and manual changes to auto, which makes me think thet seem to learn just fine what is connected?

Several years ago, my 3.2 auto got a 'spike' through its electrical system (I think battery related) which basically fried the engine ecu. A firm in Derbyshire attempted to repair it, but found it was unrepairable. I got a used replacement, which was then reprogrammed to the car by an ex Vauxhall auto electrician, and although it generally seemed to work ok, it had odd little quirks (it was about 3 -4 years ago, so I can't recollect exactly what they were now), and although the EML wasn't on, it had clutch switch faults stored (I unfortunately haven't access to the cars paperwork at moment to give the codes stored). However, from the seller, it transpired that the ecu was from a 3.2 manual Police vehicle, so the ecu was then reprogrammed for an auto gearbox, and it has been fine ever since.
Presumably then, as long as it is reprogrammed correctly for the recipitant car, it should work ok. Incidentally, it is now the best performing 3.2 I have ever driven; maybe it's a figment of my imagination, but I have driven a few over the years to make the comparison.....

Well that was just my experience with it, no clue if it actually works if I put a manual in or something, just what I observed when using "My Naff Code Reader" after battery was disconnected.
