For about the last 6 months I've been running a shift kit in my EF that I made...

The way I designed it is so you don't need a switch to turn it on and off...
When putting around town shifts are normal, but when your throttle exceeds a level determined by the user, the shift kit enables and provides a firmer shift, back off the throttle and the kit switches back to stock shift...

Reason I made this post is i hadn't seen anything like this on the market, I'll probably be looking at selling this kit as I am selling my EF (just bought a 5sd BA XR6 ) but i wanted to see what sort of interest there would be and was toying with the idea of making some more...

Installation of this kit is as basic as installing a shiftkits.com.au one, only with 1 more wire...

Let me know you're thoughts...

thats a brilliant idea, well done. 99% of the time you only want that when you are giving it some anyway

sounds alright if its proven and tested

just a modified switch to the accel pedal?

just beware that if it switches on / off too regularly, or if it switches on /off during a shift, it can make it go into limp mode

thats a top idea mate, hope you can make yourself some money, good luck to you.

I personally would only have the shift kit activated at full throttle, that way it wont be turning on and off all the time

Its been working fine for me, and thats been at least 6 months of use...


Nah no switches need to be fitted at all... just 4 wires (+12v, Ground and 2 wires from the ECU)



I was thinking the same thing and was worried this would happen, but i've never had my car in limp mode...
