Title: cluster adaptation for m-box results in no tach signal, still p1650 Post by: ddillenger on October 07, 2012, 01:22:13 PM Curious as to why this would happen. My ecu is a k-box flashed with an m-box file. I have no codes other than p1650. I have used vag-com to go to instrument cluster adaptation, and checked channel 60. The stored value of 0 results in everything working, but a persistent p1650. Changing the value to 1025 causes the tach to zero out, as well as the oil light to come on, and the DIS to display "press clutch to start engine" even when the car is started. 1027 works, but gives an error for no TCU present (its a m6 car, so coding the cluster for an auto is pointless) and the p1650 persists. Anyone have any comments?

If you are doing this on a RS4 (k-box), you probably need to change the coding for the ECU. If you do have a RS4, I don't think running a m-box file on it is a good idea. Many people on this forum are working on porting the RS4 ECU over to work with m-box cars. It seems to me going from k-box to m-box is a big downgrade in software, and would require extra work just to get it back to stock RS4 performance.

Not an rs4. I can see how that would be confusing.
Title: Re: cluster adaptation for m-box results in no tach signal, still p1650 Post by: prj on October 07, 2012, 04:07:53 PM Ah, so it's A6 K-box, not RS4...
Title: Re: cluster adaptation for m-box results in no tach signal, still p1650 Post by: ddillenger on October 07, 2012, 07:12:21 PM I'm not worried about the code causing issues, I'd just like to fix it! Thanks for the help!
And yes, it's an a6 k box!

Unfortunately, until this work is completed, our only real alternative is to continue using the M box.. Personally, I haven't had an issue using M box (performance wise) but it does require the requisite ps_w limitation hacks (KFLF or MAF underscaling) to get it to work right.. but that is true with any 2.7t. The only real issue is the airbox flapper... and potentially the cam position sensors (mbox only knows about one of them).

I personally think this is a fabricated pseudo problem.You could flash your car to K-Box right now, all you need to do is kill the IMMO in the EEPROM and code out a couple DTC's. And it would work perfectly. People have been doing this for a long time... Title: Re: cluster adaptation for m-box results in no tach signal, still p1650 Post by: nyet on October 30, 2012, 08:51:51 PM I meant to tune. I have no interest in running a stock k-box, either on a real rs4, or an s4 :P
In which case i still need a .kp or asap2 map pack... Title: Re: cluster adaptation for m-box results in no tach signal, still p1650 Post by: prj on October 31, 2012, 02:06:13 AM I meant to tune.

I have meth and map switching off of the failsafe on my K-Box as well as NLS... My car runs 23 taper 21 on K04's and makes nice power. Why exactly can't you tune the K-Box? I have a pretty good generated xdf posted for it, only a few maps are missing / need correction in the grand scheme of things. RS4Boost on here makes more than 600PS on K-box and he even posted his ols-project... as I said, don't see the problem. Title: Re: cluster adaptation for m-box results in no tach signal, still p1650 Post by: Normohl on February 15, 2013, 08:53:27 AM Not that this will work for you, but when I changed my Abox to Mbox (kept the A just recode to M) I kept getting the same code I would delete it and it would immediately pop back up. I was logging one day and cleared the code while driving it, and it never came back again. I am sure its a slim chance it will work for you but surely worth a shot...
