12 Mustang gt with 6r80 swap/built motor in Limp Mode

[droidman86]

I've read about 50+ threads about limp mode and haven't solved my problem yet. I'm hoping to find someone that might have gone though my same issue.

I recently built my 2012 motor and swapped mt82 to 6r80. Programmed ECU and crank relearn at dealer. Then tuned car with AED. Replaced throttle body/tps based on being #1 problem I've read online about limp mode.

Here's the problem:
1.Car turns on, shifts fine except it runs poorly because of limp mode.
2. Car is in limp mode
3. Does not accelerate while in (parking). Once I move shifter to (D, R, 1, 2, 3) it accelerates slowly but it does.

Is the ECU out of a car that had a 6r80?

Yea the guy I bought it from said it's from a 2011 auto

Has the car always been in limp mode or was it all of a sudden?

Only after I put the motor back in with the 6r80 transmission swap. Before I had motor built and mt82 it was not in limp mode.

When you had your Ford tech set up your PCM, did his VCM and IDS pull back any codes or issues during the set up (code numbers please). When you hook up your tuner, is it pulling back any codes?

Check engine light is off for the first 10 mins. Then it turns on, i checked dor codes and it has p0011

I'll ask around, but I found this http://www.fordobdcode.com/p0011-ford .

I've seen it already. Saw a couple people who had bad alternator causing that code. I tested mine and looks good.

Not quite sure how a bad alternator will affect Intake Valve Timing. You did mention that you had built your motor. Did you have the cams out?

I had a shop build the motor, I supposed they did have the cams out but mentioned the sprockets were never removed. All I did was put motor back to car along with transmission.

By the way, thanks for the help.

You're welcome It might be worth limping it back to the shop and get the valve covers and timing cover off and verify timing. Another problem might be a disconnected/broken sensor.

the bad news for me is the shop who built motor is 4 hours away. On limp mode it would take me a day lol.

Maybe you can get an uber to tow you Expensive but feasible, do you have a dealership nearby you can trust?
