Hi Guys

As the topic states, going to be tuning my golf 5 GTI 1K0907115E busy creating a definition file and have found so far

LDRXN/ZK
KFMIRL/S
KFLDHBN

doing exhaust and downpipe on friday, have ordered the intake and will be ordering a audi S3 IC, so will be looking at a stage 2 tune. What else will I need to look at apart from the usual maps?

still need to locate

KFMIOP
KFZW/2
KFMLDMX
KFLDIMX
LAMFA

any advise would be great.

another question, I dont seem to have a checksum option in mpps for this ecu, from the research it looks like the security mechanism on these med9 platforms uses some sort of RSA encryption. My question is if I change maps in the file do I need to checksum the file or can I just flash it back to the ecu and the mpps software will handle the encryption side?

 I'd be real careful with flashing anything MED9 without the most up to date checksumming. At least make a full backup first so when you brick it you can flash it back to life.

I dont have access to a bdm device, my mpps cable is v13 and had no issues reading the file. I will try write the original file back to the ecu and see how that goes and take it from there.

I would if I had access to a BDM. I was feeling quite confident about trying this out but your posts have made me reluctant to tackle this now......... there are quite a few local tuners using alientech cables and all sorts tuning these med9s surely my MPPS (yes its a clone) should work? It connected and read first time although it did take about 15minutes to read the whole file.

Many med9 ecu are instable during writing.

The first I've write has error during writing then no solution to repair! No solution with bdm too because I haven't make a full backup (flash+eeprom) before writing.
Cost +- 1000$ for a new ecu (few years no solution for immo off med9).

Today I make bdm backup before each flash on this ecu.

Maybe you are lucky?  Wink

I have failed a few flashes in my time, my tool was able to restart session if i did not power cycle or anything.  just restart the flash right away and it usually goes.  However, i would suggest unplugging the fuse for the fans before write!  they can and will kick on sometimes during flash and it your charger is no good you are surely making a bad flash Smiley

even if it did fail, i was able to write file on bdm(not the e2p, just flash) and was fine.

Thus i have not seen it necessary to have a full backup, but for this guys scenario, i would have a full backup.

I think I am going to take a chance, if it fails I will deal with the issue and if anything I will learn along the route. Thanks for the cautions guys.

MPPS v5 is a fake clone too) I think its better to use at least EU clone v16. But it costs around 350$
