Wiring loom swap..

[Lee Goodall]

I will be swapping the wiring loom in my 1996 A4 (AEB engine) to the newer type (97>) loom to take a newer ECU.

Will there be any compatibility issues with sensors etc.. AFAIK the lambda probe is slightly different and will throw a fault code but is there anything else to expect?

 

[Broken Byzan]

Nope should be ok, you 'may' have a prob with the MAF, but thats not 100% ad the early (expensive) MAF covers the early models so should actually be ok

 

[Lee Goodall]

That's ok then.. I have two older type mafs and a newer one in my Audi warehouse (garage) lol.

I know the Lambdas are different as I ordered one for mine and it turned out the part changed for 97> cars... I have one spare now anyway!

Got Audis/parts all over the place at the minute ha.

Yeah, I had a problem with my MAF when I spliced in an older loom... you need to keep your existing MAF and the connector for it... the other one 'might' not be compatible.

But, if you're putting in a new ECU, then you should need to use a newer MAF too... I would have thought.

 

[Lee Goodall]

Yeah AFAIK the newer ECU, loom and newer MAF should just pretty much plug and play.

 

[Lee Goodall]

..wasn't there a difference between the CTS on the earlier and later cars?

 

[Broken Byzan]

Have you got the blue/green 4 pin one on yours?

If so you are good to go. Some early ones had a seperate sender for the air con, grey IIRC

 

[Lee Goodall]

Yeah it's the four pin one :icon_thumright:

 

[Broken Byzan]

I think you should find the MAF,the N80,the ICM, the coils,injectors etc the connectors are all the same for those too from memory. You need to move closer,lol

 

[Lee Goodall]

Should be fine then.. cheers.

The journey from yours to the Mids is lovely though. Maybe you should do it more often lol

exactly what i was looking to do... let us know how it goes

Once a few things are sorted, i might just do that.....

You sorted out some fuel injectors yet for the T28?

I've been looking at some cheap OE bosch injectors that will flow 475cc/min at 3 bar and should fit the AEB rail (they're a direct swap for Bosch "fatbody" EV1's in a different engine)... Think they'll do about 500-510cc/min at 4 bar, and you can get a full set, brand new, for about 80-100quid.

You'll likely also need a new fuel pump, i doubt the standard one will be man enough to flow 475cc/min at 5-6 bar...

Worth considering then.

I was going for 415 or 440CC possibly Genesis or Delphi with the 4 bar FPR. A lot of the bigger Bosch injectors that I've seen have a narrow spray pattern.. which is obviously not good for multi-valve heads.

These are standard fit on a Vauxhall Astra VXR, and people use them as a direct replacement for the injectors on the C20LET engine, which uses the same Bosch EV1's as the AEB does.

Few on there, a couple of them brand new, and one with a 99p start.

Mate of mine has a set, so i can find out from him the bosch part number if you want to look up any more tech specs of them?

 

[Lee Goodall]

Yeah that'd be brilliant cheers mate :thumbsup:
