will my aum ecu work with agu engine

[mk4_gti]

hi i have just bought a AGU engine and fitted it into my golf only to find one side of the ECU harness doesn't fit my AGU ECU.....any suggestions?

[vwblackmk4gti]

are you using the same loom, from which you have put the engine in

[golf-sib]

different ECU's completely.

AGU Bosch 3.8.3
AUM Bosch 7.5

It can be done to get the AGU to work on the AUM ECU loom however, bit off a fiddle re-wireing. I did have a pin layout somewhere. If I find it I'll post it. One thing I am unsure off is if the MAP on the AUM ECU would need editing to blank out the VVT which is found in the AUM as the AGU doesn't have VVT.

yea i have got the car start and running on the AUM loom and ecu....however i have no power and its back firing like crazy...i was thinkin to put the vanos on the engine..will dat do any help?

are you using the aum throttle body too?.. what about the map sensor and intercooler?.. there are loads of differences in the engine set up which would need to be transfered over not just the ecu and loom..

You could chuck the vanos across, I can't see why not. However I'm not sure how easy/fit it will be, I'd imagine it should fit across though.

Obviously due to using the AUM loom, remember you need both the AUM TB present, both MAP sensors etc, so you will have to plumb the engine in the same fashion as your AUM block was, I imagine you know this since you're doing this.

well tbh honest its my first time doing this so im not really sure....ye im using alot of things from my aum engine such as loom coil packs etc etc....the original prob was when finished fitting the AGU engine, i was fitting the ecu but the left side loom connector was a diff size how can i resolve that...?

Change the loom

Replace plug with correct one and rewire it accordingly would be my guess.

thanks for the advise....but does anyone no who has had this problem before
