The car needs a driveshaft loop to pass tech (which I plan to install).

I have a datalog of the entire run. All the information is reported via the OBDII port to the scanner. It's very cool and you can log just about everything you want.

I am soooo old school. Jeez when you think about it the ODB is sampling at 40 MHz, which is probably faster than the reaction time on a recording tach. Head Bang

I figured you just read over it quickly.

I like old school and new school stuff as well. However once you get a taste of the new school you will never look back.

I figured out the problem. I had a wrong setting in one of the tables. For the transmission to shift at WOT two criteria need to be meet, speed and RPM. I had the RPM I want but the Speed wasn't correct. Changed that and the car shifted pretty good on the 1-2 shift. I haven't had enough road for the 2-3 shift just yet. I'll keep you posted.

Did you put the driveshaft loop in it yet?

Yes.... But it hits the exhaust. I need to get some heat on it and do a little clearancing. Wink

The Ford tool might be a place to turn in this case. Laughing

Wouldn't recommend a Ford tool just yet (technical term is an engineering hammer; honest to God, cross my heart and hope to die) as the kinetic energy needed to deform the drive shaft safety loop (which was designed to hold a flopping torque arm attached to 500 angry ponies in check) will wreak havoc with the floor boards they are mounted to, before you get any correction. My advise is to measure everything twice; heat to cherry red and bend it only once.

Smoke was talking about the exhaust pipe. It was kind of worded that way above but no biggie. Embarassed

Paul is correct. The engineering hammer would be used on the exhaust pipe, not the loop.

You know if I put my brain in gear before I opened my big mouth I probably could have thought of that. Rolling Eyes Just chalk it up to another senior moment. Embarassed
