Re: VW 1.8T trothel "idle Valve" discution

Re: VW 1.8T trothel "idle Valve" discution
Received one on Friday. I'll try to take a look at it this coming week.

Re: VW 1.8T trothel "idle Valve" discution
The throttle is a somewhat complicated piece of kit with nice failsafes built in.
The motor can actually close the throttle from the "rest" position - does it actually ever do that, or is it opening only?

Re: VW 1.8T trothel "idle Valve" discution
Yes, the ECU can close the throttle plate in order to stall the engine, as I've told by a Bosch ECU mapper, in the case of a engine overtemp.
In the rest position, the engine idles at -+900rpm.

Re: VW 1.8T trothel "idle Valve" discution
I'm currently only using from "rest" to fully closed as a work around. On my motor with a completely clean throttle body, cold idle without A/C on is about 1100-1200 rpms at the "rest" position. Hot this increases to 1300-1400rpms. With A/C on idle is 800-850 cold at rest 950-1100 hot. I have tried using the valve normally (rest is "closed" and open the blade with increasing PWM DC%) but the fact that TPS rises with it, going into closed loop can be hit or miss at best and rpms tend to be erratic (1200-4000rpms!)jsmcortina wrote:The throttle is a somewhat complicated piece of kit with nice failsafes built in.

Re: VW 1.8T trothel "idle Valve" discution
Any updates on this James? It would be best if MS could drive it directly, but a driverbox would also be useful. It could potentially be used with other standalone.
Thanks

Re: VW 1.8T trothel "idle Valve" discution
I've had a look and was thinking about working on an extension to what's already been posted that could also be used to control non-spring loaded bike secondary throttles.

I would also love a possibility to control the idle

Re: VW 1.8T trothel "idle Valve" discution
A servo controller like piubrazil posted is what's needed to control this idle valve correctly.

Re: VW 1.8T trothel "idle Valve" discution
Back to Top with this Old Thread.
i search a lot here to found a Way to Controll the Idle System of the VR6 OBD2 / ABA Throttle. I read that someone Switch the Cables and Run inverted or with a Extra H-Bridge Board. My Question is what is the Best Solution for it and have anyone a Schematic of the Board. Find this old Thread about it but with no End.
Thanks for all Help.

Re: VW 1.8T trothel "idle Valve" discution
It can be made to work "ok" by inverting it. There are a few of us that have been using it that way. The control board schematics are lost atm, no one seems to have saved it.
Re: VW 1.8T trothel
Inverted Mode dont work for me. Switch the Cables and the Idle Control is not Adjustable. Run MS2 and tested all PWM HZ Settings. I Think the Only Way is a H Bridge.Paul_VR6 wrote:It can be made to work "ok" by inverting it. There are a few of us that have been using it that way.

Re: VW 1.8T trothel "idle Valve" discution
Do you get any movement? These throttles are prone to sticking from pcv engine oil. Probably worth a good cleaning.
Re: VW 1.8T trothel "idle Valve" discution
It moves but the adjustment is the Problem. Throttle open is not the problem but to close it need higher percentage jumps. For example I can open it in 5% steps but to close it need 20% for 3-5% throttle.

Re: VW 1.8T trothel "idle Valve" discution
With it set up this way you can only move it on the open side, not closed. Generally this gives a 900rpm hot idle on a vr6 which is fine.
Re: VW 1.8T trothel "idle Valve" discution
Ok. But for me this is not Adjustable. I think the best way is to Drive it with a Servocontroller. No one have done this here ??
