. I am just not sure what gains I will get of the card over just leaving on 21 flywheel with standard card.....is it really worth splicing my standard loom and loosing the warning lights??? The bike is used on road as I have a Mc21 and a MC18 which I would use on the track....the HRC card does have pose value though ! 
I still have the standard flywheel which I would put back on if I was to add install the card.
Thanks for the concern though, good to know there are people looking after me an my bike.
