ASR has been reported as being way too aggressive - has left a few people in dangerous situations, slowed far too suddenly and too much halfway onto a roundabout or entering a busy intersection.

I got into the habit of switching it off as a routine in dry conditions.

After my engine and LSD (Peloquin ATB) upgrades I (mindlessly) continued that habit.

Just recently I've discovered the following happy facts:

ASR not only cuts in when both wheels really slip - it now comes in far less abruptly - in fact gently even and allows the revs to rise for the next gearchange. It seems that the programmed % cut back on the throttle goes nicely with seriously uprated power and a Peloquin LSD.

Subjectively, I feel that the car has more power with it left on - which was never the case before.... This I can't explain - may have summat to do with adaptation...

In fact - the ASR which I used to hate, I like now, it seems to actually assist spirited driving!

Wonder how the 0-60 times would compare with it off/on....

Strange, eh?

I find my asr, quite aggressive as well, even in the dry when you put your foot down too quickly you can fell it cutting in before the light comes on.

Bas, I remember Wiebo's car was fantastic once the LSD was fitted, and I never recall him turning off the ASR. Going round bends, the LSD would just pull the car round, at higher lateral gforces than an OEM diff would allow, whether ASR was on or off.

From that experience, I'd say that the LSD + ASR is probably a very good combo and both areas work together to give a much better driving experience.

Now when shall I get an LSD fitted.... :rubchin:

We had this discussion yesterday didn't we Basil. Its odd indeed. I dont have an LSD fitted, but I do have bags more power, and I too now find myself leaving the ASR on. My habit was also switch it off on starting the car, but I too find that it works as one would expect traction control to work now. It seems to just limit the wheelspin but keep the power on, instead of just cutting the power dead and bogging the car down.

Does anyone know how exactly the ASR limits power to the wheels.....i'm wondering if it has anything to do with the egr, which all in this thread have bypassed?

nope it just cuts fuel/boost.

Actually just lately my asr has felt near on perfect. And the onlything i have changed recently is the egr blank from allard.

I wonder if the asr uses the anti shudder mechanism to kill the power initially then fuel and boost after that.

As in the anti shudder valve in my eyes would kill the power much quicker than just boost and less fueling.

We need someone to reomove their bonnet get someone to sit on the engine and watch the anti shudder mechanism while someone uses the power

Any volunteers

There does seem to be a pattern emeging here......interesting.

Mr Ward could Join the conversation here...............

You fitted an allard pipe at the same time as me. Did you notice any difference in the ASR????

Hello :wave:

What an interesting thread

Power delivery has definitely felt smoother since it's fitting, but I honestly can't say I've noticed anything regarding ASR. That's probably because I tend to drive round it, and try to avoid it intervening at all.

I'll do some testing once she's back on the road

Interesting theory, no doubt, about the anti-shudder on the EGR. Just wondering how we test/prove it :rubchin:

Hmm, now that it's come up in the discussion - you know when I really noticed this behaviour - AFTER I fitted the Allards' racepipe a month or two ago.....

That may well be the thing that did it...

best way to test out this theory - that by-passing the OEM EGR reduces the aggressiveness of the ASR would be:

on a stock or remapped car test with the EGR rubber valve unplugged and blocked with a golf tee or bolt. It'll throw up a CEL after a bit, but ths can be reset with vagcom np....

We may be onto summat good here...

Cheers

or did Mr Washbrook do some tweaks on the asr contol?

I know hes done it before after reading a thread on the ukivs forum on a pd150 golf.

the plot thickens

I actually asked him this question- he said that he hadn't touched the ASR section of the map at all. He did map out the CEL light for the EGR by-pass though.....

could you post a linky to that thread please mate?

My Anni TDI with hybrid turbo - new dyno graphs added (pg2) - uk-mkivs

Towards the bottom of the first post he describes the maps.

That's a lovely Anniversary

Some nice work on it...

I've got ESP on mine just to clarify, but the rest of the story holds

And I must admit, apart from the nice power the Quaife is what I miss the most, very much means you can use the power
