Intermittent CEL light....

[LeeH]

From time to time I get a CEL light flash up, its that quick I only notice it at night and its not very often.

I have KPRO if that makes any odds.

Also it logs no fault code :xconfused:

Does it flash when it detects knock? That's my only thought so far apart from the obvious loose connection blah blah.

Any ideas?

Im far from an expert Lee but I know there is a 'preference' on Kmanager which can illuminate the EML when knock is detected.
It happened on my old CTR now and again but that wasn't mapped 8-[ I was using one of the generic maps...
Who mapped your car? Maybe give them a ring :xconfused:

HTH - though it probably hasn't :lol:

 

[LeeH]

Thanks Mark, I had a feeling it could be that :?

TDi North did it, and did a dam good job too so I don't get why it should start to knock.

I'll have to call them and get it back on the rollers :?

 

[Mark_teg]

Let us know how you get on matey

Is it doing it under load Lee?

Take it to John @ RASP mate, he can check the fuelling on his rollers. Saves you a trip over to warrington if the fuelling is spot on :xcheers:

Yes mate WOT.

That's a good idea mate, I'll do that in Feb.

Do a datalog and see if it's doing it often or not.

How clean is your air filter?

When was the last time your tappets were done?

Dodgy fuel recently?

 

[LeeH]

GM is clean and oiled.

Fuel is V Power but it has a tank of 95 in it as I got caught out, but it happened well before this.

Valves were done at its last service.

Does K manager work on Vista???

 

[MilanoChris]

OK.

It should work fine if you run it in compatibility mode.

It could be something simple like there being a small leak in your exhaust system or the exhaust itself being more carbonated. As I have found out before, a change of cat back makes a massive difference to knock detection (especially as the K20's is very sensitive).

 

[LeeH]

OK thanks mate. I'm looking at importing a charger now, so It will probably end up back on the rollers anyhow.

 

[VT-Doo]

Are you still having this problem?
If so, datalog it.

If you send me the calibration and datalog I'll have a look at it for you

 

[LeeH]

Not at them minute as its not moved since but yes, I will download K manager and do it.

Not that I really know what I'm looking at :-k
