Thanks for that Andy – and I agree that I’d run with the HRC card 99% of the time

I was thinking more for two reasons…

First being the potential resale value of a PGM unit having both a standard and HRC card coded to it – they seem to be worth more and more flexible to the user dependent on what set up someone opts for
Second being that if by having a spare unit with both cards – one unit were to go gone wrong then I’d have another unit on standby already in HRC spec to use whilst the other is off for repair.

Then there’s the MOT situation – whereby the MOT centre have to detail the mileage on the certificate etc – which leads me to consider two more questions…

I’m guessing for the MOT that I’d pull up and plug in the standard card to bring up the mileage – then carry on with the HRC card afterwards.
Secondly I’ve then wondered (and discussed with Tom the other day) That if the speedo drive is still connected – but I’m running an HRC card (which only shows the temp etc) – if the PGM 4 still records the mileage in the background?

Maybe you know the answers to this Andy?

On another note (see my recent post re the MC28 air ducts) – when I bring the bike down for setting up on the dyno – do these play a benefit or not?

Cheers
Graham
