Ok guys I need your help once again. I had my shop replace the crank sensor and it seems to have helped the problem to a degree. Now I think that my tuning may be off so maybe you can let me know what you see.

Attached is the calibration and the datalog for it. Let me know what you think.

Setup: k20a2
Greddy turbo/dp/intercooler
3 inch test pipe
evo tt exhaust
ips kt1 cams
eibach valvetrain
kpro

Datalog looks ok (AF, knock) but once you're finished the short term trim is at 26% Also you're starting the run with the water temperature at 158 degrees. At 7 lbs boost you should be able to use the stock spark plugs, so swap those in for comparison.

Ok so should I lower the short term fuel trim? This wasn't the first datalog run this was after doing at least 4 pulls does that make any difference in the starting water temp (is it higher than normal?) Also I run 10psi high boost it's just that I run about 7psi for daily driving thats why I have a step colder plugs. Thanks for the help.

The short term fuel trim indicates that the car needs further tuning.

After 4 runs you should not be at 158 degrees - is the thermostat working?

At 7 psi run the stock spark plugs - too many problems are caused by using non-resistor plugs.
