When I use it on mine, it beeps slowly - maybe a second and a half between each beep. On yours, it was beeping 'merrily' as m0rk described. This alone leads me to think your car has not got Revo. If it's had a trial, it has gone and isn't the cause of the problem.
I feel we should be looking for other chipping / mapping culprits.
indeed, ill try and get in touch with previous owner, revo was only mentioned as thats what my tuning mate thought as he came across one before, im sure we'll get to the end of this
It's bugging me! Sorry I can't post the boost log - Requested v Actual. I was gobsmacked that requested was sitting so solidly at 1350mb while Actual was doing exactly that.
I've only got experience of (several) f****d MAFs, not of poorly performing ones. With a f****d MAF, the system ignores it and goes off values that the MAP sensor gives. You'll get good boost in that situation.
Following that argument, If your MAF was dodgy, you would expect markedly better performance with the MAF disconnected. But it doesn't do that!
I'd certainly try to borrow a MAF for 10 mins - easy swap - so that we can positively rule that out though.
Looks like a boost leak to me. Block 32 is high and climbing.
Is the 5000rpm limit the same on every run, so it's an accurate limiter? Could be apr's in valet mode.
Maf still looks ok 0.35 bar. Lcr should be running 12psi, not 5 though.

Its around 5400rpm in all gears (maf connected or unconnected), ive actually bought a MAF from ebay for £40 so if its no difference Im sure I can sell it on without much of a loss, a boost leak? you mean some split pipe somwhere?
What about a mashed Cat.
We logged a guy's that came to a meet one day.
We swapped ECU, MAF, N75 and DV it didnt rev easy and didn't boost over 6psi too.
He took it to a specialist and they unbolted the downpipe to reveal a very mashed cat.
Looked like this.
Might be worth logging lambda sensor readings as it sounds very similar.

Didn't it smell? I had a car where the cat collapsed and it would hardly rev at all (and stank) , but the LCR does have two cats............
SPS 3 will bleep when it's powered up... regardless of whether the car has Revo on or not. As such it can't be relied upon to verify whether software is on the car or not. We haven't locked out any read function on the ECU so anyone with the right tools should be able to dump code out of it... whether they can make sense of the encryption is another thing though.
Is there any way of me finding out if the car is Revo'd or not? I know there is a fella local to me according to your website that does it, it all just seems a bit odd that this all happend after someone tried to read it, Ive no idea what he was using but he tried 2 diff progs and it couldnt read the ECU code, i only asked him to do it as I was unconvinced the car had actually been chipped, maybe it was this underlying problem
Cheers, ive emailed "Just Diesels" as there local and are one of the approved suppliers from your site, see if they can possibly help me out
and ive also written to who I hope is the previous owner

It certainly would make me suspicious...

Can this logging be done on freeware version of vagcom and if so how? I maybe able to test myself, i guess this is looking like big bucks if thats the case

After re-reading the thread you said it happened all of a sudden. I don't think this is your issue.
