Has anyone had any experience with them?

A friend of mine is mightily tempted by their "plug and play" kit for 1.8T 20v and was wondering whether it's simply too good to be true?

Not too good to be true, just very good and easy. A friend of mine just used one on a conversion. litterally plug and play. Also Ben Leach knows his VW's.

Great, cheers Joe.

Thinking about it, the engine in my soon-to-be-new-car is a bit weedy so might be tempted myself.

i got one and there downpipe for mine. Ben is great to deal with, very helpful and is willing to answer any questions i had. i bugged him for a while with questions before i bought it. keep an eye on my project thread, i should be wiring it all up soon.

not too good to be true, thats why it carries a large price tag

Check what they have to say about knock control on their set up.

On a turbo motor knock control is a particularly important part of the engine management system, as on-boost the ignition timing needs to be retarded substantially.

If there is no knock control you can suffer sudden and unexpected engine failure, due to the stresses that it places on the engine.

For more information about knock-control read this.

On a supplied ECU map with no knock control it could be caused by something as simple as running a tank of 95 octane fuel, when the map is designed for Optimax.

To give you some idea of how important it is, the ABF runs TWO knock sensors on standard management (and that's on a non-turbo application, which is less susceptible to knocking).  This creates a large safety margin as it can retard the ignition timing appropriately, effectively eliminating this HUGE issue.

Check if QPEng run knock control on their ECUs.

cheers DH, I'll look into that.

theres a fella on the cgti forum that modifys standard looms to run oe management.  immobiliser delete etc....
engine will run perfect that way. when i had a chat with him they were 1/3 the price of qpeng's.  there dp's look nice though

modifyed OE box and loom is the optimal setup. the std 20vt ecu is bloody powerfull ecu to be fair to it, even manages to keep all the bolts inside the engine and drivable with a variety of dead sensors  and means you also retain dignostics  that some aftermarket ecu's don't have  or if you done get the software to connect to it your stuffed and left guessing whats broken.

knock control,   on an NA enigne with a tame map it;s not needed but if you after economy or power it's essential even on NA ,  have seen quiter a lot of k jet abf's melt themselves due to a tank of crap petrol or dropping out of tune.   some of the 20vt motors run with a comonation of crap maps and no knock control have been truly inpressive,    pistons that badly damaged that they had to be pressed out the block with gurt big hydralic press
