The BPT doesn't have a electric speed sensor wire going to the ECU. Only if your car was auto and had a separate transmission ECU would it have a speedo pulse setup.

Edit - The Gtr was released with a speed sensor input to the ECU. However, if your can has an engine conversion, it's still not going to work as the pulse comes from the dash, not the gearbox.

so what am i spose 2 do then ? just not hook up the speed wire ?

On Ford Laser there's a howto on modding the cluster to get it to generate the speed signal.

can u run it without it?

bourbon · 09-09-2007, 09:25 PM

so im guessing the BG astina SP and SOHC have a speedo wire..can prove it as ive got hte wiring diagrams...but the GTX doesnt?

project.r.racing · 09-09-2007, 09:35 PM

GTX is a different gearbox therefore may have a different speedo drive system right?

The GTX has a rpm signal but not speed. Speed is cable driven, straight to the cluster.

At a guess, not many manual ECUs would have a speed signal. The speed of the car doesnt matter - what matters is what the engine is doing that the ECU is interested in, regardless of whether the car is moving. In my BA I intercepted the electric speed signal at the back of the cluster.

with the BG its cable driven but then there is a signal that goes from the cluster to the ecu... i dont no why just does and shows in the wiring...the GTX and GTR wouldnt be the same then????

LYNX · 10-09-2007, 05:37 PM

ummm maybe im better off getting the place i bought it from to install they said it would but it would cost me $90 maybe this might be the way to go because atm i'm far to busy to install it and it seems like there's alot of fiddle farting around

Dogo · 10-09-2007, 07:34 PM

Fair enuff.

But if you change your mind - if you have an electric speed signal the guaranteed location is at the cluster. Forget the ecu and look there.

Dogo · 10-09-2007, 07:35 PM

see here for an example from the BA astina
