Hi,

My ride in Octavia 2.0L/AEG/Motronic 5.9/85kw - [K&N replacement, Magaflow Can, Full decat, Custom Skirts+Spoiler, Alloys, BlueVision 100/90, Art Leather]

Here are some stats measured thru VAG before I get into the problem.

Original RPM - 760; modded through VAG - 810

Lambda (LTFT) - (-17%),(-16%)

Fuel Used - Shell Super Unleaded

O2 sensor primary voltage - 0.453v @ idle (almost perfect 14:1)

No error codes

Now, when I acelerate the car from idle, for example raise it and launch I should typical get wheel spins imho. But the car kinda misses a beat and gives out a funny sound, hesitates a bt and then accelerates, I kinda need to adjust using clutch and accel combination to compensate. This is a bit more pronounced with A/C on, I think.

Also, if I do manage wheelspins sometime - its kinda delayed, like there is a significant lag for the power to get transferred to wheels, hesitation and the lurch and then revs happily.

Not sure what the problem is but is kinda irritating in traffic etc., also specially when I want to spin my tyres just a bit...:P

Any thoughts anyone on what the problem could be?

Also, does anyone know how I can increase timing when communication is thru KWP 1281? Lemmi and Custom work only with KWP 2000 and also does not work on Motronic 5.9.:confused:

Thanks,

Could be a dirty throttle body.

Try reposting that query in the Diagnostics & VAG-COM forum here.

Can't help much, but the idle speed is within limits, and the Lambda reading says you're running markedly rich (should be more like 15:1 at idle), which tends to kill the initial engine response to a high throttle demand. So that could be what's causing your issues with wheelspinning.
