My throttle body...

[Winso]

When I bought the car the previous owner said it had the throttle body off an Audi. It does look different to what I think are standard ones for valvers. What's it off and is it doing anything for performance that the original one wasnt?

Its different. Mine doesn't have a vac pipe connected to it for example.  Has it got an idle switch on the throttle stop??

nah its a dualy, can just make out the extra linkage to 2ndary thrttle.  thing is, it makes absolutly no difference, as audi ones are the same size.  its only MK1s where this makes a difference as its smaller, but myou could fit a MK2 one to a MK1 and get same gains.  The ontyl thing you have done is loose the part throttle enrichment from cold and the ability of the ECU (ign controller) to detect the car is at idle if you dont have a throttle switch!

looking at it it might have a TPS instead? If so its handy for megasquirting
