Since October!
Surely get it extracted from that place asap and trailer it to someone who knows what they are doing —> SportsItalia.

Its not easy when someone else has been working on it , even if they buy a new ECU they will still have a problem to down load the soft ware on it .

He's sending the TCU to me on Monday, will forward on or alternatively I can send it direct to you at SportsItalia - Unit 4D Lake Farm Estate, Allington Ln SO50 7DD, I presume?

It went in for a simple clutch change but apparently there are software issues which has caused the delay. I'm pretty sure they don't have the SDS3 tool.

Yep that’s it.

Okay - diagnostics complete using EasyMAS.

The ECU functions and reports ECU firmware was updated in 2010.
Part Number is different from label.
Inputs and Outputs work as expected.

The only odd reading is Clutch Wear @ 365.32% and New Clutch Install Position @ 0.00mm.

Faults P1768 and P1763 are something to do with calibration of Fast Gear Change and the others shown are the result of the test rig.

The calculated wear plus comms issues with the canbus and various other issues something is clearly not right.

It might be that after the new clutch install that the clutch was not reset. I would also be looking at the reason for such a high wear reading which is driven by the clutch position sensor and its magnet pickup.

Steve, put it in a car and monitor the issue, reset it/set it up and see if it the behaves?

Ignore the Canbus faults, this was not connected when testing on EasyMAS.

The reason that the Clutch Wear is very high is down to the Closed Position after Install has been set to 0.00mm. See screenshots above.

The reason could be the incorrect value being set by the diagnostic tooling or something up with the clutch position sensor at the point of the clutch reset attempt.

The ECU responds correctly to inputs on a test rig.

I will return the ECU to Matt next week.

We still do not know why the vehicle in question will not drive? Why the ECU needed Flashing? What issue/faults moved with the ECU to another vehicle?

Steve

Steve, I assume similarly to the canbus error as not present, the CPS wear value will be the same or has your rig got something setup to deal with that?

The rig has a clutch position sensor and the ECU in question responded correctly to that input.

The clutch wear value will never be correct on this ECU as the new clutch position at install value has been set to 0.0 mm.

So if the ECU is fitted to the owners vehicle that has a new clutch, working clutch position sensor then reset correctly the clutch wear should then read 0 - 5% as we know.

Brilliant you guys , tech has definitely moved forwards leaps and bounds .......................this sounds like its a prime example of people meddling in the dark that shouldnt

How embarrassed would/should that garage be, had the owner naively paid out for the said new ECU to find out they had exactly the same problem , one of those situations one would love to be a fly on the wall .

Yes, new clutch value sets to 5-7% when we use EM to set it up.

If you want to plug it into my car and read the differences between them pop in

Steve, this is all brilliant stuff - I'm trying to get hold of the garage but they're closed for Easter.

Will speak to them asap and give them this info.

We still do not know why the vehicle in question will not drive? Why the ECU needed Flashing? What issue/faults moved with the ECU to another vehicle?

I need to speak to him to find out more, I have a feeling he (or the mechanic) didn't spend too much time fault finding.

@Steve4200 - So, just spoke to them and they claim that when they swapped the TCU in my car for another 2010 MCS it started up, and the other car didn't. Swapped them back and the reverse happened.

They said they are unable to write any values to my TCU which is why the readings are all wrong in the diagnostic, and why it won't start.

At a bit of a loss now, best bet may be to find a used TCU if possible.

Managed to find a used working TCU which should work for mine even if it's not an exact part match. Or am I completely wrong?

I would be waiting till Matt and Steve have had the chance to properly assess your current unit.
