Hks Turbo Timer Type-1 Speed/rpm Signal Issues

[FarShark]

I have a HKS Turbo Timer Type-1 Installed. I used the HKS Turbo Timer harness and did the following:

Grey wire to Brake Cable - Turbo Timer tested and works.

Brown wire (RPM) - Spliced into Terminal 7 of the ECU

Blue wire (Speed) - Spliced into Terminal 53 of the ECU

Now here where the issues comes up, the Turbo Timer works just fine, except the extra features (Speed/RPM).

The Speed reads fine, upto about 20km/h and then Im doing 80km/h and it reads like 30km/h - And yes, its km/h not the mph setting.

The RPM (r/min) reads 0 at all times.

Any suggestions?

Thanks!

have you calibrated the speed and rpm?

i seem to remember with these timers that you have to drive at 40 then press a certain button, to calibrate the speed signal

and rev to 2000rpm then press a button, to calibrate rpm..

pretty sure the hks usa site has instruction manuals.

Sure the ECU loom wasn't upsidedown?

I dont know how to calibrate it.. none of the instructions I got with it tell me how, and the one on the website is for an older TT.... with buttons I dont have.

The ECU loom is NOT upside down.

Its wierd how it reads speed, but its incorrect, but nothing for RPM.. I just dont get it. Can someone verify the Terminal #s on the ECU for me, I independently verified the HKS manual and the R32 Service Manual.. and they are the same as stated above.

Solution:

1. The Speed needs to be calibrated. Even though the instructions dont tell you how..

You need to get into setting mode in speed, scroll left/right to the 20km/h and then click it once. Get to 20km/h then click it again and its calibrated.

2. The Brown wire, splices into the THIRD wire up from that section. Not the fourth. The fourth wire is actually in the 5th whole up (Terminal 6). But it looks like Terminal 7 because Terminal 8 is blank (no wires). You have to calibrate the rpms to 2000rpm similar to speed.

Enjoy.
