just curious if its possible to Flash a 2003 audi 1.8T Sport 170hp with a factory tune from a 2003 Audi 1.8T Sline 190 hp?

i believe they have the same turbos same everything mechanically but differnt trim options.
Whats the worst that can happen if i try it? besides not starting..

could be an easy way for those to gain 20 ponys in 5 min!

I am not sure if that is possible only because the only reason why the 190 makes that power is because of the trim of the turbo.I'm not saying thats the case,but its a possibility.I think the best thing to do is compare the 2 files see if the maps are in the same spot.If they are,then thats a plus.Then you just have to look and see if theres any difference in the maps.

P.S I'm in the same dilema as you. I have a Abox S4 ecu and a tuned file for a Mbox ecu.I am still looking into wether I can reflash my abox to mbox without bricking the ecu or killing my car.

i was just loading them into hexcompare as you sent your reply. i will post my findings shortly. I believe the turbos are the same. i know for a fact my car has a K03s i believe the Sline uses the same turbo.

Hey I just tried looking up the specs for the 2003 sline.It seems as all the a4 in the states were 170hp versions I dont see a 190hp listed anywhere.I believe The UK got the 190hp engine and europe as far as I know.

What year are the cars? Note that if you flash an us version in a european car will need to disable the sai system

its a 2003. This is a euro file i just found out, so i want to flash a euro file into a US spec car.

Want to make sure there compatable for the most part before i do it. This is just a lil experiment to see if its doable

Vws 1.8t 2002+ are compatable, but I don't know about a4s. if you want to be safe modify your file, you should get at least 205hp with 91 octane from a k03s

any idea why the SAI system needs to be disabled???I believe all the us 1.8T had SAI with the exception of AEB engien which didnt and was the only one that didnt I believe.

if i wing it and try this. (Flashing the euro file to the us spec car) i should be able to flash right over it correct if it does not work. It would not Brick my ecu?

If the ECU hardware is the same, it should not brick your ECU. If the hardware is different, then it may or may not brick your ECU.

well the US spec HW number is= 8E0909518AF
the File id like to flash into the US ecu is=8E0909518AS which is of the same year European S-line.

is this going to be safe?

well to answer my own question i went ahead and tried it.Unfortunatly a 2003 Euro 190hp A4 1.8T_S-Line file will not work in a USA Spec 2003 1.8T Sport. Car would not start. so dont try it. Fortunatly Tonys beta flashed both files perfectly with no problems.THE FIRST TIME! I was able to reflash the original stock file back to the ecu and the car started right up. So there is no Easy solution with a factory file yet,that i can see this far. I am just starting with the audi ecu's and hese are much different then the dsm ecu's i am good at modding. i will look for other originals perhaps he 2004 audi 1.8 S-line(USA) but im not sure if it has more hp then a 1.8T Sport, or Base. anyone know?

Spen is working on dissassembly or a definition file i forget which for this ecu, 7.5 ecus are a bit different then the 7.1. I will generate a couple tunes, and post them in the near future. i will dyno these tunes as well.as well as datalog the results.

Regarding the no-start, does the later file require a different instrument cluster coding?

thats a good question, I did not think about that.
Will look into it. If it does then i might just try it again.

Did you check the error codes when the car would not start? They may have given you an idea of what the issue was.

no i did not, ill go out and reflash the file tonight and see what it says when i read the codes, ill check the codeing for the cluster as well. anyone happen to know the stock codeing on a 2003 S line?

not sure off the top of my head.But I believe on ross-tech wiki they should have a breakdown on how to code certian modules,clusters,etc.You should be able to find it through there.I will try and see If i can find it .

sounds good. i have not reflashed it yet. but hope to after my meeting.

ok i reflashed with the euro S line file and turned it over a few times, then read the codes. It is Throwing a P0513 which states "Incorrect Immobilizer Key" So this IMO is good news in a way. Anyone know or got tips on what exactly i should do to make them sync.

Did you also reprogram the eeprom? It should contain your immobilizer settings. If the eeprom contents weren't changed then it may be that the flash files use different addresses in the eeprom for the immo and PIN IDs.  If the flashes were 100% compatible the car immobilizer should be fine.

You could try re-adapting the keys with Vagcom, or if the eeprom file is similar to a Motronic 7.1.1 I have been playing with you could disable the immobilizer by reprogramming a few bytes in the eeprom.

Reprogramming the EEPROM won't help. The immo in the car is still the same and the
data in the eeprom perfectly matches with the immo (as it did before).
The two images must be made for different immo versions. The original one matches with
the instrument clusters immo version, but the new image uses a different immo version and
therefore can't talk to the immo in the car. The immo data in the ME7's eeprom is stored
always at the same places, independent of the used immo version.
You can only disable the immo to run the new image. Or if you are a really good hacker, you
can replace all immo functions in the new image with the correct ones for your car  :).

anyone know the addresses to disable immo? any info how to do it would be greatly appreciated. If i get the file working i will upload the final product so others can use it.

This has to be done in the eeprom, not in the flash. You need to dump the eeprom contents,
then program back with an update. The change would be specific for you, not useable in
general for other's. And your car will not be protected by the immo after this.

eeek , in that case i would probably be better off just modding the stock file. Going to hang this one up. Will post a modded stock file most likely in jan. or feb.

Walter

That would be a better way in my opinion, you never know what differences between
the two images are hidden and show up lateron only under certain operating conditions.
You can give most help to others if you have made all changes yourself (and can explain them).

I want to know this ! ;)

Just in case anyone want to know, if found this info: http://forums.vwvortex.com/showthread.php?4756488-how-to-disable-turn-off-immo3.-make-your-ecu-swap-plug-and-play!&highlight=ecu+swap (http://forums.vwvortex.com/showthread.php?4756488-how-to-disable-turn-off-immo3.-make-your-ecu-swap-plug-and-play!&highlight=ecu+swap)
I have read many times in other forums about immo 2 or 3 ECUs working with immo 3 clusters but not with old immo 2 clusters. I think that the case is by far more complicated with newer immo 4 or 5, according to my readings.

Would not say this is totally impossible, but I don't believe anybody has ever tried this, for good reasons.
You could spend several months in reverse engineering different images to find out how to do this  :o.

I purchased a Euro BEX ECU PN suffix AS, and had the immo turned off. The ECU works good in the manual transmission A4, US spec, 2003 models, but without the different injectors, the fuel trim eventually reaches the max adaptation limit. The turbo used on the BEX 190 hp engine are slightly different from the US AMB turbo as well as the BEX DSMICs. The exhaust manifold is a higher flow version of the AMB part too.
I originally wanted to run the BEX-AS ECU on my AMB tiptronic, but the ECU won't accept the soft coding value required for the tip trans with the AMB 1.8T. I loaned the ECU to a friend with an '03 A4 MT, and it ran well with the exception of the lean fuel trim limitation that occurred. His setup has a test pipe and a hot air intake also, that may effect the fuel trims.

You can try using APR's Immo Clone utility..But it only allegedly works on APR tuned ECUs.
 I have some screen views showing the EEPROM contents, and what to change to turn the Immo OFF, let me know if that would be useful.

I'm sure the EEPROM contents would be usefull - I am trying to get a Canadian S4 cluster (not sure about the IMMO version) to talk to a US S4 T-box and would appreciate this info - sure I would need it at some stage...?
