Been messing around with the car today after yesterdays sad rolling road's figure on my car which was due to a nice vacuum leak from the CC where one of the stupid vac line wasnt fixed to it, so I junked all the CC.

 

Was thinking of getting rid of the AIV while I'm at it but a little stuck as I've been reading a few threads saying that if you junk the AIV, you'll need to get a new ECU to compensate. Soooo, for those who has junked it but left the ECU as stock, do you have any problems with it?!

 

Oh, anyone wanna tell me where else to look for when I'm looking for a vac leak, I dont have any sort of way to tell as I dont have a vac leak detector thingiemebob.

when i removed the aiv form my Z i did'nt have any problems running the standard ecu so id have said it was ok to remove.

 

Regards the vac leak iv'e have the same problem for a while no, iv'e given up trying to find it so waiting to get hold of a compressor to do a vac leak test. :nana2:

You can get a chip that has a compensation for the AIV being removed but I think many people have done it without and its not been a problem.

just ditch it, as AIV is to do with helping the cats on the emmissions side of things

With stock ECU it will overfuel at idle when you remove AIV. Prob wont notice anything, other than increased fuel consumption.

 

I believe all aftermarket chips have the AIV stuff removed.

 

..and since a decent aftermarket ECU chip can be supplied and fitted for about £75, and improves power, smoothness and mpg and allows you to run extra boost its worthwhile upgrading anyway even if on stock boost now.

Cheers for the replies, well I'll probably leave them in for the mean time as I was at the rolling roads meet yesterday and was told I have a nice vac leak some where as I probably had the lowest output of all the TTs that day! Also they said that I am running a bit rich, though they couldnt get a reading for my fueling wasnt even on the chart! :shock:

 

Think I'll sort out the minor little problems before junking it and getting an aftermarket ECU chip to compensate.
