Jan. 3rd 2011.
I have loaded the new tune in the car.
Idle is fine when cold but goes back to 1300 RPM when warm.
My new set up has tons of things different then before. ( bigger throttle body , injectors etc. ) .
All I did is change the injector size in the actual tune and now redone the idle table.
I'm sure there is much more to do but I'm unable to go on the dyno until April 2011.
Should I just give up or keep trying a bit more ?
I have no exhaust or vacuum leak ( I know this may affect the idle ) .
Any suggestions ?
Here's the video , cold it is fine but when warm is goes back up to 1300 RPM :
...Idle test 1...
1 hour after I've decided to play with the idle screw on the throttle body.
It is now idleing perfectly.
I have to wait for the motor to be completly cold and see if I will have a fast idle on cold start up.
New idle video comming + another one on cold start up.

Idle test 2 when warm.
Idle was adjusted with the software ( like the prervious video ) but this time I have played with the set screw on the throttle body.

Sounds like your on the right path but like RamAir stated stop running it without putting load on it to seat the rings properly! Might be hard not to want to start it up and listen to it purr over the winter but better safe then sorry if those rings dont seat properly and you get blowby amongst other possible issues.

Car is back to cold so I gave it a try and it is working perfectly.
Fast idle and slowly comming back to regular idle.
The whole car is shaking , I love it.
I'm pretty much done for now so the next update will be this spring after a dyno tune.
Thanks to everyone for the help.

......Having a little issue here......
After my car idled a bit I shut it off and saw a spot of antifreeze on the floor.
It looks like it was comming from the left rear head.
When the car got cold again I took a tool to pressurize the cooling system hoping I'll find the leak.
Brought the pressure to 18lbs like my cap says
and found this :
Coolant is comming off the bolt itself.
I googled it and looks like it happen to many people , I called the machine shop and he said : Remove the bolt and apply some white tefflon tape and retorq it.
It sucks because I have to drain the coolant , remove the left header etc.
I haven't seen any other leaks with the pressurize test but I haven't lift the valve covers.
Lets hope it is the only one.
What you guys think I should do ?
I have $hit load of cash in this built and I did my best to do it right ( even if I have no experience ) the very technical stuff has been done by a machine shop and I paid for it. They said my head has been worked ( ported ) and he seems to say it has something to do with it. I don't beleive him but still.....

I assume that you put teflon paste or sealant on the bolts when you put them in? I am just asking and no means insulting your or your ability.
I have had this happen with head studs but not bolts. I, and others have put some stop leak in the radiator(for leaky studs)and fixed it.
You said it's leaking out of the back. Is that the only place? I would look at the crossover tube on the back of the heads. That has been troublesome for some people too.
It "could" be leaking out of the crossover tube, down the block and dripping off the bolt.
I would investigate further before tearing anything apart.

I looked at the pic again and it does seem that the cylinder head between the bolt and block has moisture or something on it. Obviously coolant doesn't travel upwards, not in this case anyhow.
Added:
If it it just that one bolt and you take it out make sure the beveled edge is facing the bolt not the head. I know ARP say's if its on backwards it can cause problems but I do not know exactly what the "problems" are.
I don't think because your heads are ported it would make it leak coolant there. I have seen heads that have been over ported on the exhaust side and went into a water jacket. If that was the case the coolant would be leaking inside the header and not out onto the block, if indeed that's where it's coming from.

They said : R emove the bolt and put some Teflon tape on it .
They also said because my heads are ported this can be the cause.
I really don't beleive them on that one.

If they are saying its leaking because the heads are ported I would be learey of them. Make sure if you take the head bolt out and put teflon on it, I'd use paste not tape, that it doesn't void any warranty for the work they have done.
If you take the bolt out and there is no teflon on it I'd take the engine back to them and have them do it right or take it somewhere else.

I didn't get the info about "paste" on the bolts from them but I assume they did.
They are a well known shop in Montreal area.
