I just got this update done today. I was having long crank issues in the mornings when the engine was cold but it didn't happen this afternoon when it was a pretty cool 50 degrees. I'll post an update tomorrow morning when I start it in the morning. It's supposed to be around 35 in the morning.

There is a noticeable difference in how smooth the car is at low RPMs. I've only had my car for about a month but I've always noticed now difficult it was too get a smooth start in 1st great without revving the engine a bit before letting out the clutch. My last car was a BMW 540i and I used to be able to take off in 1st right from idle, so the GTI was a bit of an adjustment.

Midrange seems to be a little punchier but it's a small enough difference that I could attribute it to placebo effect.

The whole service including a 4 wheel alignment at the dealership room about 4 hours (including them checking over some little things that were bothering me) and I didn't pay a penny for the ECM update.

Why would you have expected to pay anything on a manufacturer's recall?

I wasn't expecting to. I was simply stating a fact. There were no hiccups or anything else that the dealership might have tried to charge me for.

I have an SPS switch as well, so I went ahead and flashed it back to stock before rolling into the dealership to have my coolant pump replaced under recall (hoping the dealer wouldn't notice the straight pipes and catless DP lol). Anyway, I dropped the car off and picked it up, everything was great. My leaking coolant pump was replaced with all the seals and gaskets and coolant was flushed and replaced free of charge. I hopped in the car, plugged in my SPS switch, and to my surprise, I sat for a good five minutes and never got the confirmation tone signifying a successful reflash to Stage II. So I checked my invoice, and sure enough the ECM was retuned under 24ax and all of my tunes overwritten.

I'll be calling Revo in the morning to see if they've released a file to correspond with this. If so, I'll be driving to my nearest Revo dealer (3 hours away) to get reflashed. I got my free coolant pump at least, but the 3 hour drive on a stock tune is going to be miserable.

Update, I took mine back to my tuner (Vagwerks, just a few miles from Revo HQ) and had it reflashed the day after my car was updated. Running stronger than ever, no issues. Vagwerks has excellent customer service as well for anyone in the WV/Maryland area.

I just emailed you my EDU # and such. Hopefully we have some updates soon!

Can you explain the changes VW made in this ECU patch? Why is it causing the tuners to write new tunes? Is it because everyone is simply overlaying their tune and just increasing the boost rather than re-writing and specifying fueling and such?

Like to have some insight which is causing tuners to have to update their files. As one would think -- our TUNES would be much better than OEM VW... For example the subaru's and the factory tune being meh even with fuel request

We provide performance software for virtually every ECU ID and Revision Number possible. It's a good idea to flash your ECU with the corresponding tuned files for the ECU ID and Revision Number the ECU is current at.

It's an update that affects a large number of ECU's. That's about as much as I'm going to get into....

It depends on what ECU ID and Revision Number you're updating FROM. For example, the one you posted, 1K0907115AM Rev. 0030, does NOT get updated. Another few examples:

1K0907115AP Rev. 0010 --> 1K0907115AS Rev. 0040
1K0907115AP Rev. 0020 --> 1K0907115AS Rev. 0040
1K0907115AP Rev. 0030 --> 1K0907115AS Rev. 0040
1K0907115AP Rev. 0040 --> 1K0907115AS Rev. 0040
1K0907115AS Rev. 0010 --> 1K0907115AS Rev. 0040
1K0907115AS Rev. 0020 --> 1K0907115AS Rev. 0040
1K0907115AS Rev. 0030 --> 1K0907115AS Rev. 0040

That's just a small few, there's a good bunch more....

1K0907115AT Rev. 0040 is one of the latest updated versions one would get update TO on the 24AX update.

Right I actually just posted that as an example so people could tell which one is their revision. The one I currently have is 06J906027J SW 1637.

Any idea what this one would get updated to?

hey John, does this mean once you release an update, those of us with uniconnect+ could just flash to the latest revision?
