My Stumble prob, Traction Cont Related, Possible to fool trac ECU?

try and make this short!

 

Installed a 3800 torque converter, When launching only in first the car jolts at about 2800rpm as if it hits a limiter a couple of times.

 

Pulled the Trac fuse after i was advised it could be the trac system seeing excessive rpm with little speed, i,e trac system thinks the wheels are spinning.

 

Problem gone! but i need my trac fuse in as i dont have a built box and i use MANU mode for racing.

 

QUESTION

Can i wire in something that will fool the Trac system.

I.e. a switch/button that i can flick just on launch that cuts a signal to the trac ecu and then flick back as soon as i pass 3000rpm to retain my gearbox protection.

 

I know i cant wire in a switch to cut the trac fuse as when you switch the fuse back on you have to restart the car for the system to work again.

I know this sounds obvious, but what happens when you simply turn the traction control off? I only wonder, because you can sit on the line and spin the wheels as much as you like with the trac fuse in place, as long as you hit the TRC OFF (or SLIP CONT) switch.
