---------------Original first post below-----------------HI.
Not sure if this is something wrong with my car / map that I need to look into more or if its just a 'feature' of the dsg box.
When i've got my foot to the floor and change up a gear there is a very slight lag before the boost comes back in again. I've changed to the revision D diverter valve and I think it improved it a little but its still there... Its about 0.5 second delay before it pushes hard again.
I didn't notice this before the map.
I've spoken to Motech who asked me to come back to data log the car and possibly re map but I just wondered if anyone else has had this.
Thanks in advance
------------------------------------
UPDATE...Just got back from Motech again (
http://www.motechperformance.co.uk/) and just wanted to give a thumbs up for their customer service
Obviously after remapping my DSG GTI I had some 'lag' / 'hesitation' for a fraction of a second after a full throttle gear change. But I test drove one of their own cars today (2.0TFSI DSG) and that was perfect... so they obviously CAN correctly map this engine / gearbox combo...
Anyway... several log files and new maps later I've got a car that feels excellent again and with the problem 90% cured... It feels much better than before although I can still feel a slight hesitation still compared to their own car.
They seem committed to solving the issue though which is great to know that they dont just want to turn their back of difficult customers.
A couple of possible causes may be...
1. My car previously had a revo remap by the first owner. This was removed by the 2nd owner after lots of hassle with Revo. Revo never actually flash back the OEM stuff but instead put on their version of what standard should be. If they have done this incorrectly or put the wrong version back (for a different car or slightly difference ecu) then we could be trying to map a 'lame donkey'... So after xmas I'm going back and we are going to take the ecu out and check it properly to see if its actually got the correct software on there for the car.
2. Although there are no faults showing up I'm going to change spark plugs and look into something called an N74 valve. I've already replaced the DV with the revision D.
Anyway... Motech seem committed to finding the issue and giving me a car that performs like their demo car... even though it looks highly likely that its nothing to do with their map..
-----------------------------------
ANOTHER UPDATE....Just had my N75 changed and massive difference. Too early to tell as it was only a short test drive home but the post gear change pause seemed to almost have disappeared.
----------------------------
ANOTHER UPDATE 12/6/12hesitation still there and very noticeable on full throttle gear changes.
Now changed the following which hasn't solved the issue:
spark plugs
latest rev DV
N75
fuel filter
FINAL UPDATE 28/6/12 - Full explanation here... http://www.mk5golfgti.co.uk/forum/index.php/topic,36417.msg572115.html#msg572115I'm in a rush so will write more later but BIG BIG BIG thanks to R-Tech who 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...
