  • I assume it’s short for “Torque converter clutch position sensor voltage” and as mine is a manual gearbox it’s probably irrelevant, I’m just confused by it. It looks like the voltage is related to both rpm and manifold pressure which could suggest it was an output from Mems to the gearbox ecu controlling the CVT. It would be good to know if other people have this signal on manual gearboxes or if this is another spurious signal which was introduced when my car was re-mapped?

  • Just thought I'd share this data file. I did a 5 minute drive logging all the live data using pscan from my car. The car drives well with no problems. Note that after 3 minutes and 14 seconds it's got 155kPa intake manifold pressure (that's because it's got the 1.8 turbo engine in). However I'm a bit confused about some of the other readings and I was hoping someone more knowledgeable could help? i.e.
    • how it calculates the inlet temperature as I think the later cars didn't have an inlet temperature sensor
    • Why the vehicle speed always reads zero
    • not sure what the "Torque conv clutch pos sens voltage" is
    • or the "Adaption of throttle valve act motor"
    • or the “Additive mixture correction IV error”
    • Why injection time reads zero at 3 minutes 15 seconds
    Thanks

  • I have a re-mapped Mems 3 ECU and get a P0501 rough road detection code. I suspect that the re-map may have been done on a non-ABS car and then when uploaded to my car which has ABS. I'm concerned the ABS may have been affected and was hoping to track the live data so I could investigate further. On ABS cars I believe the rough road signal is passed from the ABS ECU on a hardwired output to pin 78 of the Mems ECU. How this works I am not sure but the signal is in the form of a square wave digital pulse train of between 0 and 5 V at 8000 pulses per mile. On non ABS cars there is a reluctor ring is fitted to the LH rear wheel and provides 48 pulses per rotation which is adapted and then sent to the same pin. I can't find this live data on pscan is this something you can add to the "wish list"? Thanks

  • Ok. I'm even more confused now. I decided to try it again ..... and it works even though it still said "programming failed" and the last digit was incorrect.

  • I've been in contact with the seller on ebay and they did use a Keydiy machine to programme the key fob. You may have been lucky that the last number of the code generated coincided with a valid code or perhaps the user of the machine selected a different model? Out of interest did the last digit of your code match the automatically generated one on pscan?

  • Thanks for researching this. I'll return the fob back to the seller.

  • It is a red fob off off ebay - see picture. I read on another forum someone had no problem programming theirs with pscan so I thought it would be ok - clearly not. Before I leave snotty feedback on ebay is there anything else I can try? Thanks
