Those anyone know about the Tems equipped track mode? I was wondering if any of us tried this on a dyno to see if it wakes the car up. The following excerpt was borrowed from the Suprasonic. UK site.
TEMS Equipped Soarer/Supra Trackday setting activation guide
"trackday settings" is a software based tuning package programmed it the ECU of TEMS (Toyota electronically modulated suspension) performance cars.
What does it do?
it essentially gears up the car for "harder driving" by:
stiffening up the damping rate for a firmer, more controlled and more "talkative" ride.
stiffens up the progressive power steering for a more direct, firmer feel
changes the preset ECU map to make the engine run in a more performance oriented manner, at the cost of fuel consumption. (example it is believed the Soarer twin turbo gains up to 30bhp with trackday settings on)
On Soarers with a Dot matrix equipped instrument cluster a sold square will appear on the dot matrix section indicating Trackday settings are activated.
1992 Soarer Twin turbo engine bay (1JZ-GTE) example
HOW do I activate Trackday settings?????
its a little known secret, but is VERY simple to do....
cut a length of wire about 4" long and strip both ends.....
open up the diagnostics port in the engine bay..
Short out the two terminals "TS" and "E1" by placing each stripped end in each port.
diagnostics port open; Ts-E1 shorted out, refer to the underneath of the diagnostics port cover for location of terminals
Let me know if it works since I nolonger have the stock ecu to try it myself. Mybe someone with a hookup with a locl dyno can post the differences.
