We installed a Magnum XL back in 2014 on my 12 GT 55D. The car is mostly stored but I want to make it a daily driver since it has low miles and i want to sell the ST Focus. Dash lights went crazy (blue moon intermittent) and the car runs like krap......P0702 came in output sensor code......I cleared the code it never came back but the speedo is lighting up like a christmas tree intermittent. There i alot of bad info out on the net. I have researched this for days. I have no box/Abbott/SGI-5e just the pigtails we got with the Tremec kit. It ran fine but this crazy ECU stuff is baffling. Why it ran fine and now this bull is what it is. I went back to OEM tune and no change.

JPC is selling the Abbott box....but I found this as well on S197 ---->
- 2005-2010 Mustang applications are a direct plug-and-play with regards to the speedometer. 2011-up models will require speedometer recalibration via ECU tuning or a separate plug-in signal converter from sine to hall-effect signal, such as the Abbott Enterprises ERA or Dakota Digital SGI-1 (Not included).
"Blew the getrag, had a magnum installed with all the proper upgrades to the driveline, it works great. 3 weeks later my Speedo quit working, every light on the dash pretty much came on, and I was sure it was due to the wiring on the new trans. Then suddenly it worked again...and it worked everyday for the following 8 months. Till last week, same issue. I thought maybe it was the signal from the Abbott conversion box, so i bypassed it, still
nothing. Read the voltage coming from the output sensor, it's working, as I'm getting AC volts as I turn the wheels. My little code reader says output shaft speed sensor circuit. But sensor is working. So this leads me to can bus, or the pcm? Any ideas?
I priced a pcm at Ford for 600
No idea how to price a can bus system

I will be calling Tremec direct since there is not alot of concise info on this. Again it ran like a beast when True Street tuned it to 423hp at the wheels N/A motor.
The AM written word above is vague. You can tune it via ECU tuner? Abbott calls it Pulse Ratio.....Abbott ---> However, this Pulse Ratio can be made to vary from the true when modifications are made which change the number of electronic pulses per mile on a particular vehicle. This is most commonly caused by changing the tire size (increasing the outside diameter of the tires will cause the tire to travel further before making a complete revolution), but other modifications could have the same result. When the Pulse Ratio is thrown off, the speedometer/odometer will be inaccurate and corrections must be made.
pulse per mile vs protocol sine vs hall 2 different things
Your tuner should be able to use the abs wheel speed sensors to calibrate your speedo, but you won't have cruise in any gear.
