I do not mean to mislead anyone. So just so I can get it straight, the 944S2 chips are 32K size Tue, 09 Sep 2008 07:44:11 GMT T_Voigt http://autos.groups.yahoo.com/group/BoschDME/message/416 http://autos.groups.yahoo.com/group/BoschDME/message/416 That looks funny... The first half is 1267356229 code. The second half is 1267356132 code. Nothing modified so far, but the images are from two different Tue, 09 Sep 2008 07:01:09 GMT FR Wilk http://autos.groups.yahoo.com/group/BoschDME/message/415 http://autos.groups.yahoo.com/group/BoschDME/message/415 Hi Mike, Your 944S2FCS.BIN is the first half of chip 126735229. Your 90944S2.BIN is the second half of the code. The code has no errors except someone put it Sat, 30 Aug 2008 16:55:33 GMT Mark D'Sylva http://autos.groups.yahoo.com/group/BoschDME/message/414 http://autos.groups.yahoo.com/group/BoschDME/message/414 ... What is the Bosch number on the chip? It will start with B57xxx You can look up the number to determine what type of EPROM is in there.

But since the whole code is in the chip, it is possible to shrink it into the lower 16k. You may place Sat, 30 Aug 2008 04:55:56 GMT efidabbler http://autos.groups.yahoo.com/group/BoschDME/message/412 http://autos.groups.yahoo.com/group/BoschDME/message/412 Guys, Has anyone ever seen a 16K chip in a 944S2 DME box?? I read it several ways and as a 32K, the top 16K is all ff. I thought these were supposed to be Thu, 28 Aug 2008 15:45:11 GMT Alexis Pavlov http://autos.groups.yahoo.com/group/BoschDME/message/411 http://autos.groups.yahoo.com/group/BoschDME/message/411 Hi, I've already given you my opinion, your only chance is to disassemble. Another point is that Audi have always used special Motronics. Even when based on Thu, 28 Aug 2008 07:34:18 GMT WhizzMan http://autos.groups.yahoo.com/group/BoschDME/message/410 http://autos.groups.yahoo.com/group/BoschDME/message/410 No, program it to vary on 14.7, that should work. If that doesn't work, it's in the code of the motronic, not in your original lambda probes.

It looks for a switching frequency and tries to keep it switching. Very different from wide- band.

Don't expect to find it easily. Closed loop code is very complicated in Motronics.

I think it closed loop target. I dont know where target is.

There may be a single value that the closed loop targets for. 14.1 is hardly rich
