well, it actually wont.. as its adpation will pull 15% out as seen in block 032 trims and it will still maintain its requested lambda request.
Its working the fuel pump hard for no good reason also.
Cheers for eplaining that, I wasnt sure if it would pull the duty cycle down or do it via trims as you have said. I guess either way though the end result is still the same, if you were to up the fuel pressure mechanically the ECU just thinks the car is too rich and pulls back fuelling to reach the requested lambda value because thats what the map is requesting.
I visited this particular tuner about 10 years ago when I had an issue with my Mk2 Golf 1.6 Driver where it would accelerate to about 75mph tops and never go past it, it would go really flat. I checked a few things but as I didnt know the car very well at that point I figured it would be worth paying a "vw specialist" to take a look at it for me and diagnose the issue.
The response I got after a diagnostic and rolling road tune up was "its not a GTI so what are you expecting" Obviously I was not too happy and replied that I still expected it to be able to go above 75mph. His advice was to fit a webber carb as that would improve performance and solve my issues as he blamed the old pierburg carb as being old and unreliable.
On getting home I looked into pricing for Webber's and ended up buying the conversion kit and fitting it all myself, took the car out and surprise surprise the issue was still there and it had made no difference at all. I then spoke to a nice chap at webber who was a carb expert over the phone and described what the car was doing and instantly without even seeing the vehicle or having any VW specific experience said "sounds like a timing issue to me".
Out I went and pulled off all the timing covers to discover the belt was out by about 2 teeth on the cam. I had never even thought to check this as I had receipts stating the car had the timing belt done by another well known garage not that long before I had bought it so never once for a minute did i think it would be this !
After redoing the timing belt the car went like the clappers.
It now seems that even though that was some time ago, this company seem to still be going down the same route of trying to sell you something to fix a fault that should not exist if they indeed are a "specialist" in that field.
People can make up their own minds here but I think that some of the replies in this topic speak for themselves. I certainly wouldnt be even considering going back for further mods when they seem to fail to be able to sort out an exisitng issue that was soley caused by software they have flashed onto someones ECU.
