No o2 sensor fitted. Its a 06 mdel. I'm also speaking with dynojet but im not really inspired so far. I will have a look at the suspected connectors after ive finished my breakfast

Ok so I managed to check the connections and they were fine but I cleanef them up anyway. I had a quick look until the tank and a few connector blocks just looked rotten so I will be looking there next week.

so connectors checked and cleaned didnt work, I also tried putting the origanal connectors with each other and still no reading. So in light of the poor looking connectors im going to investigate under the tank checking all connector blocks.

ok more a update and after some tips now.

so there's been emails back and forth with powercommander, so far we've tried swapping all the connectors back to stock to see if we can get a signal and so far no joy, so far the CPS and TPS have been tried, the next step i assume will be to remove the PC completely and go from there.

It's looking more like the dash is not recieving the signal but the ECU and PC are. so i'm guessing now i'm looking for a bad connector or broken wire. are there any usual places where the wiring rubs through or are there any connector blocks known to be troublesome?

also i'm after any tips for clean corrosion from connector pins? i tried using a file gentley but that didn't really seem to clean the pin to well.

Contact cleaner and a toothbrush works well, but even better is to by yourself some dentist's hand tools of ebay such as this plaque removal hook...

Their ebay shop has lots of other surgical tools useful for fiddly little jobs.

The other (and perhaps best) way is to separate the pins from the connector block by releasing the tab on the back of each. It's fiddly, you'll need surgical tweezers and takes patience/time.

Have a read of this thread from the HUBB...

I always have a stash of tooth brushes in the tool box for brake cleaning so thats good then. I'll set to work and report back when i'm done.

Cheers

Ok so today I really managed to get into. I completely removed the pc with no result so its something with the bike. I came across a number of really horrible connectors. But the 2 main connectors under the tank just did not want to seperate so I think the problem is in there. If I get something like a month off work with nothing today I would get replacing connector blocks. But so far the problem remains.
