Hello, this might be a tall order but if you can assist please do...

I am looking to remove many components for weight reasons, etc...etc... So I understand that I'm going to need resistors otherwise check engine light will come on. I'm curious; in regards to if anyone has attempted or completed a complete lightening effort and can advise me of what/where to research to keep the ECU happy. I am interested in removing the seats, which have airbags, so I would need resistors there, all of the rest of the airbags from the car, so would need to know the impedances and other aspectsI should consider. I know that on a 2006 corvette, if the radio is removed the check engine light will appear, so if the same occurs with the 2000 S4 I would need to know how to trick the ECU there also.

A good side question is, if the check engine light would come on, but the car would still run completely fine and be completely drivable, and/or I could turn those components off some how that would also be another avenue of interest. What I am trying to avoid is calling electromotive and do without the Audi ECU...

Thanks,

Shawn

 

You will have a very hard time getting a stand alone to work as well as the BOSH ECU. It's a real good one.

You will not throw any codes for the radio, just have stored codes. A lot of sensors you can shut off with Vag-com.

If you want to know what kind of resistor to throw into the airbag, why don't you just test them & match? I also think, you can shut off the A & C piller ones, as not all A4's came with them.

If you really want to drop some pounds, remove the AC, get a CF hood & trunk, move the battery to the trunk & get a LTW one. The stock seats are not super heavy, the rear seats don't weigh much at all. Oh, just removing, or draining the washer fluid will save you 10lbs of fluid.

 

Thanks 2k S4 but “testing and matching” is not my idea of fun... I'm wondering if any of the guys on here have done anything like this, or anyone doingSCCA racing strictly, or built a car for trackand using the BOSH ECU would have run into this. I might have to give 2bennett or VAST or similar to see if any of them have done anything like this...
