Researching ECU options for my R400 to upgrade from the unlockable Caterham one. I have looked at Emerald and SBD but am sure there are 100's of other options. Anyone have experience/advice they would like to share and make a recommendation?
I just up-tuned the motor with headwork, roller barrels and dry sump and am prepping for a dyno trip. Nothing done to the lower end BTW.
