Did you tried check with non zero velocity and verify that RPM & speed match at given gearbox 2nd, 3rd, 4th, etc?
these formula (RPM and speed) match well with my real dashboard
i haven't verify with the gearbox if speed= K x RPM
Anyway, is it possible find on CAN/VAN in Peugeot cars something like wheels angle turn caused by driver manual steering wheel?
I think this data (steering angle) can be found in the ABS/ESP module
this module have a Kline (iso 14230-4) on the OBD connector
but i don't think that this info is on Van bus body (perhasp on the other van bus)
i will try with PP2000 if i can see this angle directly from ABS/ESP module or from the COM2000 module
Actually I work on Kline ECU (EDC15C2) and i can get some info
(speed, rpm, water temp, air temp, fuel temp, boost pressure, accel position,flow injector, batt volts, ....)
and made a protocol converter (with PIC) for bluetooth adaptater to see data on my iphone with TorquePro.apk
but that need a big work to fine in the data frame ECU where are the good data and their encoding formula
(and i have burn my adaptater with 12v on 3.3v ! )
but this not the subject of this topic
