Stage 3 cam cold start tuning HPT

Anyone have any success in this area ?
i would like the cold start to stop the ridiculous surging and hunting.
The s1x cam in my l67 would just have a higher , but smoother idle at cold start then settle into a lope

the is3 cam in the l26 gets retarded before settling in.
Any suggestions ?
 


Have you tried messing with the Open loop AFR tables and closed loop function. Like have it stay in open loop longer or bringing closed loop sooner. Adjusting the target afr and timing in the idle area's??

There just really isn't a whole lot we can do it seems because we can't control the IAC and any other throttle body functions.
 
Thanks for the suggestions
Well from what I gathered , was to run it rich and decrease timing and then I heard the exact opposite as well

curious to see if anyone else runs the is3 cam and hopefully they also use HPT
 
DH always said to dump a ton of timing at it in idle and that would smooth it. I never had the chance to try it though.
