Cossie M3s not loping :(
Lower timing to 3*. Force open loop at idle and re-tune AFRs for 16.1:1 during idle ac/off only.
With AC on. 10-12* of ignition advance and 15.5:1 AFR. Raise RPM to 1000 with AC off, 1200 w AC on. Tune your maps accordingly.
The higher you raise timing at idle, the less it will lope. Same goes for AFR, the richer the AFR, the more stable the idle. Don't lean past 16.1:1 at idle with AC off unless you know what you're doing. Much leaner AFRs are capable at idle, but must be done carefully...and by a professional tuner that knows what to look for.
I run as lean as 17.5:1 at idle w/AC off, 15.5:1 w/AC on. You may have to play with the MIVEC maps as well on the IX to get the desired lope you're looking for. I suggest increasing overlap at idle.

Thats basically how I induce heavy lope too. Before I realized it was more of a nuisance than anything. I spend more time trying to get RID of heavy loping these days haha.

O btw the grey car that has the super lope was a guy that decided to do no valve train and just threw cams in by themselves. I don't think that makes a difference, but can't you just mess with the overlap...cam gear time
Thanks for the input guys

In with john bradley... you are off timing. M3's at idle should lope if your timing is where you say it is. Even with it pig rich it should lope still.
Edit: Shouldnt even idle at 850... no way its on time.

OK wait so am I off a tooth on the intake side, exhaust side, or crank pulley? Because even if the intake side was off a tooth, wouldn't adjusting the advance have some effect on the lope? If so, then the intake cam can't be the one that's off.
Unless you are off more than one tooth (retarded). 15 crank degrees per tooth, so you could be a couple teeth off on the intake and even advancing the cam wouldnt necessarily make a difference.
