Nothing wrong with ECUTek unless you want to spend big $'s on Motec to gain very little extra (which is fine).
And the ECUTek launch control is fine too.
With all these sorts of things you just need to look at the cars running them & how they perform. ECUTek (MMS) tuned cars have been ultra reliable and won lots of MC autokhana events, MC circuit events, SES Events, Speed Dome Superkhanas, Max Action Autokhanas and this year's Classic Challenge.
So ask yourself...what's wrong with (MMS-tuned) ECUTek?
Might not be "fashionable" but they win!
