Blitz MSTT Speed adjustment
 

Hello!

Maybe someone of you can help me!

I have a Blitz MSTT in my 92 Supra.

The problem is that the speed which is shown on the MSTT is not correct!
At a speed of 100 km/h it shows me a speed of 130 km/h.

Does someone of you know how I can adjust the MSTT?
Or what kind of signal does the MSTT get for the Speed?

Till now, no one at the german Supra Forum could help me!

Greetings
Daniel

the most i could suggest is to find the speed signal wire on the blitz computer and verify it is connected to the correct speed wire on the ecu

i have a friend with an older blitz computer, i shall have a look at his and see what colour wire is for speed on his and get back to you :)

The wires are connected the right way!

From the Blitz it?s the orange - black wire and on the ECU it?s the (on the wiring diagram no. 9 of the first plug) pink wire I think. (Europen Supra MK3)
I don?t know if you have the same colours of the wires in the states.

The problem is that the MSTT shows me to much speed.
My high speed on the MSTT was 399 km/h!!!
If I drive 200 km/h it shows me almost 300 km/h.

I think the Signal for the MSTT ist to fast!
But I don?t know how I can slow down the Signal!
I think I need a little wiring which I can connect in the speed signal wire on the MSTT!

But I?m not sure!

blitz mstt
 

how do you fix that problem?can u help me?i bought blitz mstt but Kmh had a problem

Hello!

You have to switch on the mstt that the speed is displayed.
Than you have (sorry, but I don?t remember which butten) to press and hold one buttton till the speed is flashing.
It will show (in my case) 40 km/h.
Than you have to drive this exact speed and push the button again.
After that the speed is adjusted.

I hope I could help you!

Best regards
Daniel
