i would live map on the road,

i too have not had any problem with emerald at all, there so helpfull,

i had no problems with it on my focus RS

i had some wiring issues with it regarding coil on my 24v cossie lump, which they spent half a day doing reaserch for me and gave me advice on what to do. in the end it was sorted thanks to the back up at emerald,

imo, i will never use anything other than a K3 on all my future projects, unless they release another ecu lol, but all the upgrades for the k3 are also free via emails,

also mate if you wanted a k3 fitting, i can show you how to map it yourself if you buy a wideband and det cans.

you cant blow an engine up unless you do sumet stupid,
you can make them underpowered if its not right

pm me if u want any advice or info or to know about my experience etc
