Cruise control does not work after changing the gearbox.

[macinek102]

Hi, I have BERLINGO III. Is it possible to set gear 5 on the engine controller permanently? I changed the gearbox to a faster one (from the Peugeot 307) and now the ECU cannot "see" the gears and will not activate the cruise control. Or maybe some other solution?

Hello mate, I had similar issue with jumpy after change gearbox and the solution was change gear box type with lexia interface.

The ecu don’t know physical what gear selection has the car, ecu use an algorithm with vehicle speed and rpm to calculate gear swifts.

Best regards

Yes, I know it, but changing the gearbox in Diagbox does not help, changing the size of the wheels in ABS is not :(

[macinek102]

Nobody knows the solution? Changing the parameters of the gearbox in ECU and ABS did nothing!

You need to change gear ratios of your map for the ones of the donate car

I know but I can't do it, that's why I'm looking for help here.
The gearbox is from Peugeotta 307 (20DM75) 110 HP. When I tried to upload a flash from 307 the starter would not work.

Hello mate, when the garage change the gearbox the came to me to change the parameters from ecu, I tried many options without success, when maps detect speed and rpm are not pairing the system disconnect cruise control

only gear ratios, v/n gear changes and v/n max and min thresholds need to be adjusted in order ecu knows correct speed and thus make cc control working properly.

here try this i'v corrected ratios to similar gearbox you described. Shod work fine.

cruise control works great, but recently I increased the power, and now it has standard power. I have to choose now, cruise control or more power, but thanks.
