Did Mick not sort it then Pete ?
Did Mick not sort it then Pete ?
You know my opinion. Told you at Brands the first time it happened
will an aftermarket ecu stop the car going into limp mode 100%.
Not with any certainty because the car performed flawlessly in testing so if I can't find anything wrong I can't fix it. This wasn't a simple code reading session either and I normally have a high success rate with these kind of gremlins but I scoped, probed, prodded and metered just about everything which is why we charged him for the hour only and made a few guesses at routes to go if it came back on an event.
Unless the fault manifests itself on a more regular basis I think he's got the right idea as I've seen people try to fix problems like this and lose a small fortune whilst at it.

Unfortunately it didn't error when he had the car, so all he could do and did do was check each component (TB\Pedal etc) clean connections, conductivity check and rectify any faults brought up after diagnostics..of which there were none at the time. So apart from strip the loom out and manually check each wire not a lot else could\can be done I expect.
Bummer really, as a couple of days ago started to fit the Aim data logger, which connects to the ecu, got the electrical fault light the 1st time I switched on, typical.
So sent the Data logger back - money can be spent better else where (can hear Jay hand to head ffs'ing lol)
That's where it's at - money and a fair bit either way to resolve. Strip the loom out and find the broken wire or after market ecu and dash to stop the fault interfering with the car (and when the broken wire shorts, smokes catches fire i'll know where it is).
At least I tried the far cheaper option first.....will an aftermarket ecu stop the car going into limp mode 100%.
Yes, fo'shizzle providing you put in a decent infrastructure to hook it up. Personally I'd ditch everything Renault put in and start again.
Just a shot in the Dark here Pete , we had the very same thing on our cup , intermittent limp mode you could literally flick the ignition off and straight back on and it would be fine for a bit , sometimes days . It was the reason the owner sold it as his garage could not track down the fault .
I am Lucky enough to be good friends with Richard who runs Westbourne Motorsport ,the Clio Cup team , we knew the fault was there so it went straight into their workshop , and they finally traced it down to a broken wire .
The wire broken from memory was under the gearbox and was something to do with the relay that supplies power to the ecu , i can ask exactly which wire and where they found it as it might be a common area that the loom gets pulled ....
Took them a few days but they found it , hope this gives you a pointer , but they worked it out to a common area from the faults that had been logged on the ecu which were many and different .

it seems obvious, but has the throttle body been changed yet? 9 out of 10 times it's the throttle body. I've even had the same TB cause different faults on different cars
A mate of mine had df129 on his cup and it turned out to be the vvt solonoid! Work that out. Took ages to find and it was doing the same thing as Pete's.
I think it was DF129... I'm going from memory here and really need my notes on his car to say for sure so it could've been DF125 or similar. Deffo a pedal track incoherence fault though.
I'm certain it's wiring and not a component fault but as money is a constraint I didn't want to waste time.
The solenoid valve is totally unconnected but "French car" so never say never and I have one as a test rig. The problem is the bloody car performs faultlessly when it comes to the workshop so it's a no win.

Do you think it might be that then Dan ?

I know where it is, can it be replaced on the day track side, simple\easy to remove\refit? If so I'll try and get down and pick one up before next weekend...
Thought you were coming over this afternoon?
Looks better Pete, you wouldn't know. Have fun At Mallory.
Might be there Saturday weather permitting, not on track myself but an old mate is in an MX5 and I said I might go and watch him with my son. (if the sun is out lol)
Cheers Tony, not so sure about the stripe though myself.
Didn't like to say, the stripe looks nasty.
Black or white would look better imo.
