spankit Posted August 26, 2006 Report Share Posted August 26, 2006 So the 2006 mkv Gti has ecu software allowing 200ish bhp. This is compared, apparently, with the 2007 mkv Gti that has updated ecu software allowing 220ish bhp. It is being said “compression was dropped from 10.5 to 10.3, the GTI engine was updated in the late 2005 (November IIRC) affecting cars delivered in the early 2006.” The consensus is we all take our 2006 mkv Gti’s to the dealers with a mythical ecu problem, get the ecu re-loaded with the new 2007 software, and drive away 20 bhp the better. Is this true, should we be forming an orderly line at the dealers? link from uk-mkiv's Link to comment Share on other sites More sharing options...
mojo55 Posted August 26, 2006 Report Share Posted August 26, 2006 i read this last week and have tried to book mine in at the dealers 3 times on 3 seperate days, each time being told service lines are busy i'll take your number and get someone to call you to arrange your car to be booked in. Guess what... my car is still not booked in.. vw eh whata waste of time. Link to comment Share on other sites More sharing options...
Spot Posted August 26, 2006 Report Share Posted August 26, 2006 My week 12 Gti (Reg 22/3/06) has a BWA engine no.... ..and I suspect Oli's must have too? What power for Oli's then with the Revo???? Link to comment Share on other sites More sharing options...
SMB Posted August 26, 2006 Report Share Posted August 26, 2006 in theory , a higher compression ratio should give more power at the same boost, I suspect that vw changed the compression ratio to sell the gti into countries with lower octane fuels ( date of change is just before release of USA version of the GTI, where they have 89 and 93 octane. If someone from the dealer network can confirm this sw exists, and which engine codes can have it applied, if it is available for both an AXX would deliver more on a given map with quality fuel.

edo Posted August 26, 2006 Report Share Posted August 26, 2006 New software def exisits, as my car was updated about 2-3 weeks ago. Saldy this took me from APR 250 down - so I cant say if it is better that stock 197 or not. Anyone who wants to dyno it is more than welcome.....

Simonl Posted August 26, 2006 Report Share Posted August 26, 2006 Matt R should know or at least be able to find out. Or RR could ask Loders, i know he has a very good relationship with them. Link to comment Share on other sites More sharing options...
Simonl Posted August 26, 2006 Report Share Posted August 26, 2006 What we need is a friendly dealer who's more than happy to update the ECU's or find out what problems would get the dealer to update them for us. They probably won't have a clue about the performance gains, and when it comes to insurance (we never knew either ) It's just to iron out a few issues etc . Anyone know of such a dealer... i'll be prepared to travel. Link to comment Share on other sites More sharing options...
silentandy Posted August 26, 2006 Report Share Posted August 26, 2006 Is anyone that's going to AMD in a couple of weeks putting their stock GTI on the rolling road? Link to comment Share on other sites More sharing options...
RedRobin Posted August 26, 2006 Report Share Posted August 26, 2006 Yes - My ECU is stock and dated July 2005. Also, you are going I believe (and hope!) but you're not booked for the dyno. However, due to my hardware mods and their supposed efficiencies I'm expecting better than standard torque, though not much bhp gain if at all. LeMan > Yes, I can happily ask Loders but would like to know more specifically exactly what I am to ask them. It needs spelling out for me - I am prone to having pink moments!

silentandy Posted August 26, 2006 Report Share Posted August 26, 2006 Yep I'm going and know you are but was more interested if there was someone with just a stock 06 GTI going on the dyno. I'm tempted after hearing about this mysterious new updated ECU but I don't feel my engine is any more powerful than my previous 05 one. Link to comment Share on other sites More sharing options...

[/ QUOTE ] 06 cars came with the paddles standard and also had a roof aerial IIRC. Red Matt R should know the right questions to ask. Sounds like the ECU upgrade is a 2006 calendar year thing not an MY06 (which would have shipped in July/August I think) - might be wrong though. My car was delivered in Nov 05 what engine code should i look for? Link to comment Share on other sites More sharing options...
spankit Posted August 26, 2006 Author Report Share Posted August 26, 2006 Red you have a 2006 axx engine/engine software. Bwa started end of calander date (not model year) november/ december 2005. I think... Link to comment Share on other sites More sharing options...

[/ QUOTE ] Merlinman, power will be determined by the level of boost, as the boost is controlled by the map, a remap wouldn't deliver any more power on a bwa than a axx as the boost control woulo dbe the same, if a map allowed for more boost, then you could get more power.

Matt R Posted August 27, 2006 Report Share Posted August 27, 2006 Right, I will check more into this on Tuesday morning. But I am now on my third GTI and have driven around 10k in each. First two were both AXX engines and my current is a BWA. I have also driven many customers cars too, Personally I find it very hard to notice any difference between the two. I also find it very hard to believe that ALL BWA are performing 20 bhp over stock claims and feel an ECU update will not do this for you. Perhaps the ones claiming it are cars that are overperforming as there has always been cars that do vary on Rollers due to temps etc etc etc. My mate had one of the First customer GTIs remapped by AMD and his AXX engine came out at 207 bhp iirc, whereas I have head of others only getting 197bhp. I will have a chat with my licensed technician on Tues and report back. Matt Link to comment Share on other sites More sharing options...

stevie_d Posted August 28, 2006 Report Share Posted August 28, 2006 Very interesting reading this! I'll be at the AmD RR day, so will be interesting to see what she runs However, I was alsways a bit dubious ove rthe GTI power tbh, a mate's bluefin chipped ST wasn't leaving me and that's supposed to be running 250bhp...

Is yours standard ECU map? (I've forgotten). I'm hoping it is - Just for the sake of GTI comparisons. Link to comment Share on other sites More sharing options...
