Hi, anybody can tell me any idea to set vehicle speed?. Mine its very bad, 3º gear to 7100rpm show 104km/h and really correct speed its about 155km/h

Add my log

Thanks

Go to Sensors/VSS and Gearbox.
sensor type Hall
Falling
frequency divider set to 1
enable pull-up
Then set Speed Ratio until vehicle speedo (Or your GPS) and EMU log match. I run about .852 to get my speed to match MPH. If you have an electronically driven speedometer in your Toyota (most 93+), check the capacitors in the cluster. when they fail and leak, it will cause incorrect speed reading.

mine is set to 1.5 but its an import with kmh clocks and im displaying in mph . how acurate it is is another thing , i dont think its far off

1994 celica ST205. Then I have to play with frequencie?? Stock dash run ok compare with GPS.
One more time, thanks Scott and anybody.

I have '92 MR2 JDM and using divider of 1,469, seemed to be closest I could get with a laggy 1Hz mobile phone GPS.

Some of the MR2 speed sensors are NOISY!! and virtually unusable, but the wiring is getting pretty old, so that's to be expected.

I just set the cruise control, to give my phone GPS time to get "accurate" then dial in the speed ratio, or adjust it on the dyno.

as i said mine is set at 1.5 , was at the strip yesterday , terminal was 132 , logs say 140 so not far off .

Thanks gays. Problem solved. Have set to 1,508 and run perfect.
