It will be nice to try and find out whats going on which some of these DSG cars and delayed shift.  I will help me understand more and help other tuners who have this issue.

I'm presuming the problem had by the OP is the same as me from the description, which I would describe as deliberate engine torque reduction post shift. There's no problem with the speed of the shift per se - the dsg works fine - it's the way the engine torque is interupted during the shift. On my car it was most noticeable if you had WOT and shifted manually at or around peak torque (say 4000 rpm).

Yup - nothing wrong with the engine / gearbox, all software:

I had a Shark map on my K03 car, which dwelled horribly on an upchange. I got nowhere with a resolution of that map, so took the hit and went for a straightforward local option and now run Revo software. Not a hint of a problem with that now on the car.

From logging the MAF the revo map appears to make much more power, especially in the mid-range. I'm not saying Revo is the be all and end all, just that in my case the problem was clearly demonstrated to be the Shark software.

I'm in a rush so will write more later but BIG BIG BIG thanks to R-Tech for stepping in like a knight in oily overalls to save the day.

DSG lag now a thing of the past AND lots of problems with the Motech map resolved.... basically by ditching it and doing a customer R-Tech map.

I should have gone there from the start and will now only ever recommend mapping from a company that have the time, equipment and expertise to fault find and diagnose should something go wrong.

My car feels awesome again thanks to R-Tech.

More will be explained soon...

The Motech maps are actually written by Richard Washbrook (ex revo and APR apparently) so was confident it wasnt just a 'kid with a laptop' that was going to mess with the car.


So at least it wasn't the remap  :popcornsoda:

Glad you got it sorted, rtech to the rescue once again :drinking:

I'm happy to eat my words and equally happy to state that I will not be taking any other cars to motech or recommending them and I've sent a long detailed email to them with todays findings and look forward to their response.

Great news, I was confident it was software related all along as I had seen it before.

Goes to show the difference in software quality.

Would love to know if a backup copy of the old motech map was kept, would be interested to see it and see if it came from the same scource as I think it did.

You will laugh at this Dave,    After I finished the one above I started to tune another 2005 mk5 Gti which already had a stage2+ from another tuner.  I read the file off and open in ols and found it to be the exact same map as the motech map but with the LDR raised by another 20% and the n75 I reg maxed to 100%.   

Send me an email to my mobile and i will send you the backup over, nokiafix@hotmail.com

....That is very scary!  :scared: - It shows yet again the importance of going to a tuner with an established good reputation and not to be led by only a cheap price.

So... Very enlightening day yesterday.

Again a huge thanks to Nick at R-Tech http://www.r-techpower.co.uk/ for all his help.

Really highlighted the importance of getting your car tuned by a company with the tools and knowledge to fault find and properly diagnose the car

So I'm happy to eat humble pie and admit that it seems the map that Motech applied was pretty poor. Nick checked their software against a known DSG map and found an area of code that conflicted. In his words he had "seen it before and presumed it was an area in the engine map where DSG and Manual differed but this confirmed it for him". He applied the DSG code to the motech map and I went out for a test and the issue was 100% solved instantly. I can also confirm that all of the drive home and driving last night the DSG change is now quick and punchy and the power is straight there afterwards like there is no let up atall... or im lamans terms... How it flipping should have been after Motech mapped it.

In short.... Motech had uploaded a map to my DSG car with Manual coding in it and this was affecting the power after the gear change.

The fun continued when we put the car onto the dyno..... which came at a VERY VERY lucky time for me as just as my car was put indoors... this happened.......

http://www.mk5golfgti.co.uk/forum/index.php/topic,49887.0.html

Anyway.....

Motechs stage 1 now adjusted for DSG ran 214bhp@4467 and 284.9@3247

The worse thing was Nick showed me the N75 duty cycle was at 98% the whole run so the poor little turbo was working flat out to try to meet the levels Motech were requesting. He also said the fuelling was very heavy (hence my constantly black exhaust and dirty rear end)

Nick lept into action and checked the car over and ended up changing the PCV as it was showing signs of sticking intermittently. This got us to 225bhp but the turbo was still working flat out.

He checked and changed the DV as my 6 month old rev D DV had broken and was bleeding a bit of air. He has advised I get a rev G now and said that everyone should listen to him that rev D are poorly designed :) Unfortunately a new DV didnt cure the power or turbo effort but at least I know its not going to fail in the near future now.

He then decided to completely remove the motech map and apply one of his own that he then spent a long time tweaking and customising in between various power runs. The end result was:

R-Techs Stage 1 custom ran 234.3bhp@5599 and 281.8@3131 The N75 duty cycle was also down to 85% in the middle of the run so much healthier for the car.

Nick has advised that I get the pre cat knocked out and then run the car for a month. Because of the motech over fuelling its likely that the cat is pretty bunged up at the moment but now the fuel levels are reduced this should burn off and allow it to breath better again. I'm also going to try to get an air intake to help with the flow as well and then return in a month for another few runs and hopefully with will then be a nice healthy stage1 with 240+

So all in all Nick spent about 6 hours fixing someone else's mess  :drinking:

I urge anyone looking at remapping their car that is close enough to use R-Tech. If thats not practical, use a tuner that has a dyno and knows what they are doing!!!

@ R-Tech Nick:

You might wish to comment about the G vs D revision DV in this thread:  http://www.mk5golfgti.co.uk/forum/index.php/topic,49862.0.html

Keep up the great work, Nick  :happy2:  If I wasn't happy with JKM, you'd be the man!
