Just wondering. If one were to get a replacement ECU for the S60R and have that tuned, say by IPD, could one take his or her ECU off, set it aside, use the tuned ECU and replace the original when it was time to take the R in for service? I take it that the data in the original ECU might not be quite up to date but how is that your fault? The dealer would not see a re-flash as having been performed. I looked on the net and found an ECU for under $900. My extended warranty was more than twice that. If this were possible, it would be a way of tuning the car without great risk to the warranty, or am I missing something?

Re: replacement ECU (Shipmate)

I think your ECU is "mated" to your car. In other words, you can't just swap in someone else's. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0">

Re: replacement ECU (Shipmate)

I imagine you could prevent some sort of flag, but if you messed up your engine and threw the clean ECU back in the car, wouldn't it be weird that there were no codes being thrown? I think for the $900 you could just save it for a rainy day (something not covered because of the ECU). The car is eventually going be out of warranty sooner or later.

Re: replacement ECU (Shipmate)

I happen to have 2 ecu's (long story) that are both mated to my car. One is stock and one is an ipd unit.<br>I think the codes are stored in the CEM not in the ECU as I remember when we were looking for some codes with the stock ecu it still said something to the effect that mods had happened. This was a long time ago, haven't needed to swap back in over 2 years now and no I won't sell it. <br>It wouldn't work anyway.<br>Once an ecu is programmed to a car, it's for life cannot be programmed to another car.<br>The only way it can work is to buy a BLANK, brand new, never used, ecu. A used one is like buying a piece of metal sculpture, no good except as a paperweight

Re: replacement ECU (JRL)

Virgin or not, the ECU and CEM car must be programmed to accept one another, so if the goal is to avoid a dealer "discussion", it's not gonna do that. In some models, the BCM is also involved in the decision btw.<p>Yes, it's a conspiracy.<p>Tom.

For $900 couldn't you just get a softloader and just program it back to stock before you go in for dealer service? That seems like the smarter route to me. <p>~Aldo

Re: replacement ECU (JRL)

Hey JRL, my dealer said swapping ECU's out would cause a difference in mileage between what is stored in your gauges and what is stored in your ECU. 2 different computer storage areas that cause suspecion if they differ a bit. I think Cloaked was going to ask his dealer too while his car was in the shop.<p>Have you heard of this? or is it possible? Might be a scare tactic.<br>

Yes you can swap out the ECM and yes it can be detected if a tech was to dig hard enough. I think it would be a great thing to do but you will have to have the ECM programmed and I don't know if that's included in the 900.00 price tag and as far as I know the dealers are the only ones that can do it. If I decided to keep my car I would do it. As far as the mileage reading goes, it's not going to throw up any error signals. It probably wouldn't even be noticed unless you were to arouse the techs suspicion. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"> <BR><BR>

Re: (cloaked)

If you really want to take the time I believe IPD (Scott told me this when I bought my ECU upgrade from him) will re-flash your ECU back to stock before you take it to dealership and subsequently have IPD re-flash back to it's upgraded state as before.<p>Some time after my ECU was upgraded by IPD (and I went down to their shop to have it done) Volvo came out with some kind of ECU update for controlling the sudden rpm drop in hot weather climates at around the 3000 rpm level when in first gear (JRL will no all the details). IPD told me to simply have the Volvo ECU update done which would return it to pristine stock condition and then return ECU to IPD for a re-flash - which I did.<p>Not sure if this is helpful to you but then... <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

The softloader will be a more cost effective option when it's available

There is always the BSR/PPC route, see eurosporttuning.com
