Darkness - the guy Steve Hillary could be a great shout, checked out the links there, as well as moto rapido he also owned Dr Desmo that I have the Dyno print out for the bike from 2004, will definitely give him a call or possibly an email might be better to put down all the info.
Cheers
Davey

I'm surprised Moto Rapido chose a Power Commander rather than remapping the original ECU.

Moto Rapido didn't have the facilities to reflash ECUs back in 2004, which probably explains the Power Commander. I had a PC III on my S2R 1000 and Wilf mapped it for me in 2007. They didn't have the ability to reflash until a couple of years later, if I remember correctly.

Heck, they want 98 euros for the Fiat lead I can buy all day long on Flea Bay for 5-10 quid... Chortle.

London Electronic (website: lonelec.co.uk/lonelec.com) only rushed me 25 quid for a Fiat lead and a UK-built and tested ODBCII USB reader guaranteed to have the correct serial FTDI chip in it (as opposed to the Chinese clone/knock-off chip you might randomly get in a 5 quid no-name Chinese item).

That said; for anything other than checking a map or maybe twiddling/resetting some minor settings, you're going to want a pro with the right gear; it makes no sense to try to flash maps and test-ride them against your butt-dyno (which are notoriously easily fooled); you really need instrumentation (at least wide-band lambda) and a rolling road.

Because it's tough to find a private driveway long enough to let you see what AFRs you're getting under load at the top of 4th. Or how new PWM parameters work out for closed-loop boost control.

It's also hard to over-emphasize how much more efficient logging makes tweaking the map - as opposed to trying to do it in real-time.

Spug. Can you use a standard OBD2 code reader with the leads if you don't want to use a laptop? I've got DucDiag on an old laptop and it works fine, but for just checking/clearing error codes I think a small handheld device would be easier for me. I'm not so keen on the blue tooth because you still need some hardware (phone/tablet) to get the codes ones but that's something I may consider too. Cheers

Steve Hillary replied to my email, he does remember the bike and did work on it but only really offered the advice to get it remapped.
But the main development - I got speaking to the original owner of the bike, Jim Allwood, who was more than helpfull putting together some of missing pieces, he used the bike for a track bike and spent a serious amount of money on it, but I still can't be sure how much (if any) of the engine internal are as per the spec I got worth the bike, what he did confirm was it had Corse throttle bodies with twin injectors, they have definitely been removed, if the 'G' spec cams are still in there no amount of remapping will get the required amount of fuel in there.
The bike is currently with torquetronix, a local guy over here in Northern Ireland that specialises in ECU mapping, so will hopefully find out soon enough if it can be re-mapped to suit the current state of tune.

Progress update:
The bike is still with Torquetronix over here in Northern Ireland (and has been since 21st June) but the ECU is with CJS (Bristol), reading back through the thread, Slob had suggested CJS as a potential place to sort out the ECU so hopefully it's in the right place.
CJS have stated the ECU is no use (parts missing and not accepting being flashed) and he doesn't know how the bike was even running so I'm now looking for an ECU, have been told it must be a 59M, if anyone has a 59M they would be willing to sell - send me a message, I have put a post up in the 'I want' section also.
Has been a frustrating summer with some decent weather and no bike to ride but hopefully things can start moving in the right direction if I can pick up an ECU.
Thanks
Davey
