Hi all, I need some quick ideas from you guys.
I have a 2008 R32 golf , NA , stock and I'm trying to squeeze all I can out of it.
Its a me7.1.1 st10 so me7logger doesn't work, but vcds can log anything listed in the FR.  Four values take 0.1 sec.
The problem is that under WOT in 3rd gear or even from a brisk launch, the logs show no torque intervention from the dsg, but timing is pulled, sometimes upto 6 degrees average, starting around 1600 rpm and does go lower but continues to 4500 and sometimes above.  I have shell vpower 98 RON plus 10% toluene and running 0.86 lambda. Apart from the lowered lambda, from 0.9, everything else is stock.  What do I do next? Is the factory timing so bad that I need to  retard it, or do I go even richer?

Problem sorted. Ecu needed battery to be disconnected for a while. Damn thing remembers knock retards for a long,long time. Now no retard on the toluene mix.

Absolutely, but I gave toluene a go since its already in gasoline. "Fuel A" unleaded reference used by EPA has already about 17% toluene and 30% total aromatics (benzene ring containing chemicals like toluene xylene etc). I would not risk methanol, that's for sure.
Basically it proved that the ecu is factory tuned to find the best safe advance and keep it there for quite some time, rather than testing the limits often. Once the toluene was added to 10% by volume and battery disconnected for a while, the retarding vanished.
Next time I get around to it, I will try just 5% toluene.
The whole idea was to see why retarding was happening, and it was because of the stock timing being a bit too aggressive, although I did not expect it to remember it for so long, thinking that the ecu would check at least every time the car had been turned on and off over a few days.  The toluene gave the best 0-60 over days of testing with dragy.

All his futzing with fuel mixes may have caused his fuel trims to drift? I don't think there are any long term KR trims but I could be wrong.
