Thanks for the post Chip and everyone for the replies

I'm loosely familiar with Ecuflash, there is a lot of info on this on the MLR and EvoM.net too.

My Ecutek map just needs a tweak really, but not sure if they lock the maps? Would be a pain, but not impossible to remap the whole thing from scratch I guess...

Just got to fit my Innovate WBand and get myself a decent EGT monitor too.
