Possible Tune issues
Possible Tune issues Hello,
I recently installed a camshaft in my 2014 camaro ss. The setup is as follows:
long tube headers
KN /CAI
TSP 235/239 cam with supporting springs, pushrods, etc.
Stock plugs with MSD wires.
The car made 471/423 on the tuner's dynojet.
I had it tuned by a well known local tuner, but I am having some issues with the car. I had it tuned because I am pretty inexperience with FI tuning.
Attached is a copy of the tune as well as two log files.
What happens is I will be WOT somewhere between around 4500rpm and redline and the car will dramatically cut power and flash "Service Stabilitrak" on the dash. One other odd thing is the oil temp will go from normal of like 200 down to like 135 and then begin slowly climbing back up. The tach and speedo will also "stick" or bounce when this happens. I have read this can be anything from the Tune to Plugs to a battery to a sensor going bad.
What I have noticed on both of these logs is right where I get the error, for one frame, the commanded AFR goes from 12.50 to like 4.XX or 5.XX, and then goes back to 12.5. does anyone have any ideas?
This is the main issue, but there are a couple other small annoying issues as well. The car seems to want to push down the road at lower rpms when coasting (like 1000-2000rpm). I noticed Throttle position with my foot off the gas is still like 15% in these situations, is this normal?
Second small issue is that if I am coasting with the clutch in, but car in gear the rpms will stay at idle. If car is rolling in neutral rpms will begin to slowly climb from idle up to almost 2K rpms.
Any advice or help is greatly appreciated, thanks.
