Changing ECU

[DeeTurbo]

Wow. Thats certainly done well then!

Nah, I'm not keeping the car much longer so not gonna look into it, I'm almost certain it's an injector fault though, but no codes are present currently.

Yep, it has severed me well. It's only ever broke down on me once and that was my own fault I risked a long journey with a noisy low pressure fuel pump. The pump started to make a funny noise the night before a trip from Wolverhampton to Watford. It got down to Hemel Hempstead then the pump packed in and I was stranded in the M1 roadworks blocking a lane. I should never of tried it and I should of got a new pump that morning. It was my second week at a new place of work and I thought it worth the risk but I ended up being four hours late. That was when I had 140K miles on the clock. Um, I might get a back up pump now as this ones done a little more miles then the first lol.

Thing is if you reset with generic OBD, the PP counter doesn't 'see' it I'm fairly certain.

I thought the PP counter simply stored other data with the reset and it was that which clogged up the space in flash (ie, storing the history of resets)... so there is only finite space (like 10 texts on old phones haha)

That is what I believe any way... possibly worth seeing if there is a 'reset' counter in PP to clear all previous logs and start again at 1.


Not sure which memory is used for fault code logging either... starting to read into the different chips a bit now so might be able to advise better in the future. I have a feeling the 8 pin chip storing the car coding (security), immo data, and car config data (matches to BSI where required) is where fault codes go. If that is the case maybe it does have a limited reset life-time.
I'd have to get an ECU and force codes a few times, then reset via generic OBD, then check the flash mem on the different chips.

Then do the same again but reset with PP, and then check again hehe...

Uh, tiring work but interesting

I shall try it on my girlfriends car, she's got a 206 with the same engine but hers is the three plug version ECU.

I'll try on her car to check how many slots are left then clear a fault using my old ELM unit and then see if the slots have gone down.
