To address my current issues, I am considering taking the steps to keep my 2000 TJ in open loop at all times.
Does anyone know what steps I have to take to do this?
Basically my engine runs and shifts great when cold, and then falls flat at 4200 RPM when it warms up.
I have a topic on the Stroker Basics forum if you want to read the details of my dilemna.

anyone know if by disconnecting the coolant temp sensor if the PCM will stay in open loop?

Re: stay in open loop
It appears it does, but you would need a piggy back tuner to make that work. However you will have a check engine light on. I had put some thought into this and I think if you put a resistor in that gives the resistance of a low enough temp the engine light should go off, unless it throws a code similar to "engine hasn't reached operating temp in x time". Also, if you have a 97+ (IIRC) your dash gauge won't work any more. You will also need a Wideband O2 sensor to see your AFR ratios.
