New to site. Ford Ranger 2017

G'day Ranger owners...
I have just retired, (Christmas time), bought my Ranger in 2017 to tow our 22" caravan around Aus.
Updates, Roo Systems towing and touring remap and 3"dpf back stainless exhaust upgrade, hopefully lowering exh gas temps, had a warped exh manifold, "not a good start to towing".
Recently had 3 error codes while towing (auto trans was in sport mode at that time), P02ED, P061B, P062B.
My Ford dealer did a PCM update 2 days ago. This update has set the "map" back to Ford specs, now they cannot find what caused the errors. Dealer believes the errors were caused by Roo Systems remap.
Does anone know what the latest PCM update does to the vehicle?
Thanks,
Jim

Hi, maybe go back to where you had the remap done and see if they will flash it again, they should still have it.

If you get the error codes again then you will know what caused them.

I never tow in Sports mode unless I am climbing, all it does is raise the engine & trans Temp and uses lots of fuel.

Doubtful the codes will come back, would just about put money on it the tune caused those particular errors.

Latest update is pretty good and has improvments across the board including better fuel economy. There is no written list.

I got the same codes come up today while overtaking.
Just down into limp mode while still in the right hand lane.

In the past 3 weeks, its been pushed harder than it was today.
Was in sport mode too (manual selection), towing, bpt performance tune.
