has anyone experienced problems reading their flash when they had REVO installed?

It's my understanding that Revo protects it's code by disabling conventional ODB2 serial flash. I assume you mean read over ODB2?
It also alters the EEprom which is a problem if you reflash over the Revo maps.

i find that to be pretty much bullshit on their part. especially with the trial once it has already expired. Going to make an appointment at renn-art and have the factory map put back on.

according to revo they state in their trial faq that you are able to rewrite the ecu with another file. they also state that reading is disabled to prevent pirating. I have located and posted the factory .bin for the 2003 a4 1.8t 5 speed in the original section. I am going to put my battery on charge and give it a go with the factory bin. ill post back tomorrow on my findings.

I am not sure if/to what extent the EEPROM is changed, I'm having trouble sorting hard data from the general forum noise. It would be wrong for me to claim this stuff as fact when all I have done is research internet info!
I am generally pretty distrustful of obfuscated code running on my ECU.

I ran into a Revo tuned car that was "IMMO defeated" by Revo. As soon as I reflashed it, the car would not start. Had to disable the IMMO manually.

I have a Revo Stage 2 and was waiting for Tony to produce a Windows XP version of the Nefmoto flasher to try a read, although I was preparing myself for failure due to the aforementioned issues.
I had a quick look at my ECU and it has not straightforward to remove it for a bench flash because it has a protective cover which requires the retaining bolts to be heated up to remove them. Sadly, that's too much hassle given its location in the plenum with risk of physical damage or electronic corruption to bother just for curiousity's sake.

I have done it on the MK4. Not that its useful in any way. Its the same MK4 I mentioned earlier with the IMMO issue. They have protection on their tunes, and quite frankly, there is not much to get from it anyways. You can just make a better remap on your own. |

Oh, I totally agree. I basically just said that because there are a select few on here that always hint how horrible the tunes are from the big names. I wonder how they can be so bad that someone relatively new with limited resources (no dyno, big $$ for r and d) a lot less man-power, is expected to produce better results? I'm sure you have some thanks to offer the big guys to have gotten to the point you're at? I've had more than a few different off the shelf tunes and have generally been pretty happy with them over the last couple of years. If it's so easy why are there not more tuning companies out there? It seems the big companies are making a killing. I tune standalone engine management systems for a living from 4-5 different companies, so I'm well versed in the "art" of tuning. I actually tell people it is more a process than an art I go through when tuning a car. Finding what each individual engine/setup likes as far as spark/fuel/boost is not a black art. It's trial and error..Less so when you get familiar with specific engines/setups. I'd have standalone on my dd if it weren't for mandatory emissions testing. It seems with motronic, it's 90% figuring out the internal architecture and what means what / what effects what, and 10% actual tuning. Once everything is decrypted then it comes down to tuning. I understand there are multiple ways to come to the same result with ME, but like they say it's not "magical". Would you say your tunes (gonzo) are better than the big names, and why?
