Which would be the best to go for? I'd be trying to source either second hand but I haven't heard much and the AEM. Are there many places that do mapping for the ecu's?

I do have the original ecu and matching key and ignition to sell to go towards the cost.

You could ask Chris Mason on here, I think he had something to do with building a MK Indy with a S2000 in it

Why not use STD ecu and get tts to use hondata software on it.

What's this tts hondata about?

u2u replied. i think hondata is like a piggyback system for thr oem unit.

DTA S60Pro on mine. I know others have also used Emerald with success.
