Purchasing 2nd ECU for 2.8 30v, am I crazy?

**mattyt** · 01-16-2009 02:40 PM

Hi, all,

I have a 1998 A4 Avant Quattro 2.8 30v Tiptronic, and I'd like to have SpeedTuningUSA.com do the "flash" on it. I see that I can get another ECU for ~$100:

http://www.automotix.net/usedautopar...inventory.html

I would have Automotix ship it to Oliver at SpeedTuning, flash it, then have Oliver ship it to me.

Anyone have any experience with Automotix? I emailed them to double-check that the ones for $91.90 are correct for my car, but is there any way to tell for sure from the information provided? If there is something wrong with the ECU, will it harm my car to install it?

Are these dumb questions? Am I crazy? :)

Thanks in advance :)

-Matt

You have to make sure it is the same ECU box code.

Pop open the ECU box and write down the #'s - then go on ebay and search for that #. You can usually find 2.8 ECU's for dirt cheap since not many people have uses for them(vs a 1.8T ECU).

Like HERE you could offer the guy $50 and see if he takes it. verify your ECU # first though.

Thanks, akielb. :) I've never tried to find the the ECU #, is there a "HOW-TO" somewhere? I did a quick Google search but haven't found anything yet.

^ Simple open the ECU box and look at the serial number on the ECU. He is saying this just to confirm you do not order the wrong one. My browser is giving me problems, but you can find the link on this page for DIY: http://www.audidiy.com/b5a4.html

second. as long as its the same box code it should work fine.

I have three 3ECUs for my B6. Two are spares sitting in a box (one stock and one stg1 flashed) just because.

Thanks, y'all, should be enough to get me going. :)

also check out ebay for the speedtuning chipping. I was looking the other day and you can bid or do buy it now for like 150 plus 20 shipping or something like that. I think its 250 on their website.
