Hello!

sorry for late response life has been very busy.

So it wont accept FF. it accepts FE (or any combination of HEX numbers) and sets the speed limit to 100mph

ofcourse, this is fast enough, maybe speed limit is set to 100mph from factory on 2019 transit custom? i have a feeling that complete speed limit removal is probably buried deeper in the ECU and forscan perhaps isnt powerful enough to change those parameters?

ive been reading on the very latest transits coming out in the future that its going to be near impossible to change the speed limits set from ford factory?

regards,
Alex

A) In all cases, it is dependant on the software level of the model.
B) If the model does not meet the speed rating criteria, speed limit is enabled within the PCM
C) It is also dependant on the speed rating of the tires. That in itself is a major factor, including the GVW of the model.
D) Another factor is engine design, the manufacturer will limit engine RPM in order to not "explode" the engine.

With a factory tool, limiting functions can be changed but "module programming is required".
Module programming is limited to the correct strategy of the vehicle. See points "A to D".
If the strategy is not available, some functions may still be limited.

Another avenue is a tuning re-map.
Dependant on model year and if the dealer recognizes a "re-map" you can kiss your warranty "goodbye".

Most importanly. The PCM does save data and sends all that speed data to the Airbag control module.
That is how the "need for speed" is identified and lands in the court system.

Ford is not interested in the liability since the "Transit" or other large vehicles do not pass a wind tunnel test or high speed stability test.

If there is a "need for speed" take it on the race track or get one of these.

Hello all,

An apology on my behalf, in the instance of my van the original method does work!

It’s just the limiter function that isn't able to go over 100mph.
The van will in fact, go over 100mph and leads me to believe the actual speed limiting is removed.

Regards,
Alex

So o tried connecting to my 20 plate custom. Forscan was unable to determine vehicle and I was asked if it had a custom PCM to enter the details.

I have no idea what it is so used the example forscan gave and it connected.

I entered the values mentioned and was able to change it but when writing it said incompatible value. And that was the end of that lol.

A 60MPh limit is no good doing 200 miles a day

Sounds a strange one. Which adapter are you using to connect?
If you want to PM me your VIN I'll lookup the asbuilt file and see if there's anything out of the ordinary.
