bad idle with S60 computer

I just plugged my S60 computer, 40%+ inj., 3 bar map and my idle is very rough.

When started at cold it stalls or swings from 600rpm to 1200rpm. When hot it still stumbles but from 900rpm to 1100rpm

I was aware that this set-up would be more erratic but how much is normal?

Is there a solution to stabilise the idle without changing the whole set-up.

So you have your car back

Have you asked Stephane about this? He's familiar with this setup.

The super 60 cal is actually too lean at idle you should swap out it out for another cal from CI
http://www.enetwebs.com/steve/calinno/

or another aftermarket one.

Remember also that the Super 60 cal has no O2 sensor feed.

good luck man. I have the same problem. I struggled with it for a year without before td.com. I tried everything. I run turbo 1 computer. Have not been afford to put anything else in it. Its very hard to live with that idle. Have you a AFPR hooked up? I believe i tried the bumping up of the idle to no effect. Try it and see. The computer has been on the shelf the last yr or so. I have addressed getting the computer re cal'd or a T1/T2 computer re done but no one answers dude.... Please let me know how you make out witht the situation.

If yall have the Mopar Performance Parts 2.2/2.5 FWD manual, on page156 and 157 it tells about adjusting the A.I.S. ( Automatic Idle Speed )motor to compensate for a new camshaft profile. This also might be nessesary for other air/fuel modifications and may help with the computer change.
