[part QUOTE=logger;600533]Pretty sure I worked out why my 98 Ron tune spontaneously stopped working without me switching anything.......
Have just finished reading this whole thread.....phew!
Your posts were very informative and as I read them I kept hoping for a favorable
outcome regarding the issues you were experiencing.
Sounds like all is now good with your 118 TSI so just wanted to say that's great
news and you must relieved
I do, but I seem to be switching to Program 2 nearly every time I start the car now, with unpredictable results when I lean on the accelerator.
From my limited experience, it seems the best way to get the most from the car is to just drive it in whatever mode it is for 20 minutes to allow the engine to warm up, then when you get to a road where you want a bit of performance, pull over, park, switch to Program 2, and head off again.
Pretty sure I worked out why my 98 Ron tune spontaneously stopped working without me switching anything. At some point I have had a fault in my Ignition switch that spat "Electrical Fault in Circuit - Intermittent" messages on four separate terminals. When this occurred it appears to have interrupted power to the ENG ECU. Cutting the power to the ECU means the the APR software will default to program 1 when power returns. In a standard installation this is Stock mode.
So all I needed to do was re select the 98Ron program in position 2 and all is fine and beaut again. So a power interruption in the car resulted in the ECU reverting back to the stock program. While I was aware the 98Ron tune performance gains were missing and the car was driving like stock, I was not prepared to try switching it back on. I wanted there to be no doubt that I had not meddled with the switching in any way to cause the fault.
So nothing wrong with the APR Tune. The cause appears to be a transient fault in my car that had the undesired side effect of deselecting the tune. Happy camper again.
3 laptops, 3 x hex USB + Can cables, connect directly to the can wires. There is no limitation on the can bus talking to different modules, the limitation is 1 laptop / 1 USB connection / 1 VCDS cable per laptop.
So if you connected VCDS cable to hub and hub to 3 laptops with VCDS program, that wouldn't work?

Hey guys, I was just wondering, the power fluctuation issues so many are experiencing with the tuning, could it be related to the fact that the cars have a torque limiter for the DSG equipped cars?
Shame you can't use the VCDS to monitor multiple modules at once say engine, dsg and awd.
