Can't deny the effort and expertise of JKM - or their customer service.  But its so frustrating and I'm wondering whether I'll ever get to the bottom of it  :sad:  I'll leave it in JKM's hands until they say that they've exhausted all possibilities, but seeing as they've looked at almost everything logically connected with the problem, I'm not sure what to do  :confused:

OMG , thats some report, its clear that there are a only a few places that would go to these lengths to sort this out, JKM are  :happy2:
Clutching at straws from reading the doc, I considered a flow reduction somewhere between pump and injectors (if thats possible)
Pump etc can supply but on the other side injectors flat out trying to add more fuel (which isnt there), the spikes happen as the flow reduction happens (i.e. the pipe backs up) . Would need to be prior to injector feeds for it to effect all injectors.
Anyway what do I know ? lol just postulating.

JKM will sort it  :happy2: its just the longest and toughest diagnostic issue this forums ever seen  :confused:

AFAIK Keith has been in frequent touch with Revo... but TBH, they'd do exactly the same as he's done going on what Revo have said to him.  :happy2:

As said in a previous post, im having issues with my car.

The readings from the long term fuel trims are the opposite to yours, im seeing the readings decrease to upto -25%. Still trying to get to the bottom of it.

Have JKM looked at any of the 02 sensors at all?

Im currently lookng at the lambda values and fuel measuring system values...

Hi Dan... I'm not sure if JKM have looked at the 02 sensors (whatever they are  :grin:) but I'll ask Keith a bit later today as he's in the 'office' as its the RR day today.

Just tried downloading the diagnostic report, but it downloads out of format and gobbledygook. What version of word has been used?

Sorry to hear that you still haven't reached a verdict on the issues you are having with the car :sad:
If I could help I would, but it has gone WAAAAAAAAYYYYY beyond anything I could help with.

Only one thing I can suggest to help you feel better and that is to give the wife the ED30 and then Turbo the hell out of the R32 :evilgrin: :jumping: 8)

How about binning the Revo and get a custom map installed?
With those sort of mods and that power i wouldnt want a generic chip on my car.

the docx format comes with Office 2007.
To view a document if you are using a lesser version of Office , you will need the appropiate patch from MS.

I always tell folk to save such files in rtf format for universal compatability of the end user.

I thought it maybe the 2007 version - cheers Bacillus :happy2:

Cheers Steve for the PDF. I've downloaded it to digest, but it doesn't make particularly look good at the moment.

I can't see the point in Illyun binning the REVO for anything else as lots of other cars are running REVO and are fine. He'll only run into the same issues elsewhere and probably wouldn't get anywhere near the support he's got from JKM. :smiley:

Thanks for that Steve... got the report from JKM and it was in Word format - I use Office 2003 and when I tried opening the file, it said it had been produced on a later version of Word - must be 2007.  It looks ok on my laptop.  I also have Adobe Professional, but didn't think of putting it out on pdf format  :ashamed: :embarrassed:  I'm sure JKM will get to the bottom of it, but its a very rare and subtle problem  :sad:
