Ls drag racing best ecu?

Just want some opions what is the best ecu systems for drag racing applications and why. Money is not a factor. Thank you

"Best" may mean different things for different people, but Fueltech seems to be developed primarily for the American 'drag' market - and I know they have an option for using that neat height sensor for chassis-ground monitoring, so you can maximise load transfer without excessive lift.

Thank you do they have any dealers in Australia and do they have a good tech side with information and help if need be.

That was just one option- others may have similar sensor options. As you're an Aussie, Haltech may be a better overall option, but there are many, many other capable options - you will need to see what fits your application, budget, and future plans. Eg, any intentions for forced induction, individual lambda/EGT, electronic throttle, do you need integrated control of an auto' transmission, etc?
