Perspective definitely appreciated
Just for the record I'm not anti-tuner... the problem is, I'm anti-bad-tuner... For example, the boost oscillation at high load in 6th gear would drive me crazy as I rarely downshift to pass. To me, that seems like something very easy to fix with the proper approach to tuning the PID. Again it seems specific to the downpipe...
I'm not looking for a ragged edge tune, just something that has a little more punch and isn't putting the turbo in jeopardy or generating obnoxious cylinder pressures. This is my commuter and since every SUV now seems to have 400hp, I could use a little more power
I have been burned by bad tunes in the past, and felt I wasted money on a K03 flash for my S4 that didn't last long - something I couldn't really resell either, which then led to k04's and a 4 year long tuning debacle that was never resolved. The last thing I want to do is blow up the turbo, get suckered into a K04, conrods, another tune, etc... I have been makin' it rain cash over the years and really not getting my money's worth, at least in my opinion. For that kind of scratch I'll be putting GT's and a 3 liter in the S4 thank you...
I guess my approach was from the standpoint that I trashed the S4's old crappy tune, put hybrids on the S4, tuned it from a stock m-box, and it's a monster now...
Anyway, if there was a safe and easy way to read and flash via OBD, the checksumming may be something I can hack, since I reverse engineered that on the S4. I've found a few .ols files and a2l's, for the GTI, which I would think may at least offer a starting point to locating maps like has been done between the various S4 boxes by identifying the offsets and shifting the definitions... I may be completely wrong in my belief though. But it sounds like flashing over OBD isn't possible with galletto.
I also saw I can get ECU's off ebay relatively cheap - the question is - is there anything above and beyond the immobilizer that would prevent me from using a different ECU? I have read various comments before about ECU swaps being a dealer task - just didn't know if that was truth or speculation, and if I'd have to clone the serial eeprom, etc.
At this point I am just rambling and it is steak and beer time...
Thanks for the input
