Hey guys, ended up with a free Greddy Turbo Timer from a friend, Unraped. Installed it with a friend last night and it turned out perfectly. Fairly easy intall. Still need to hook up VSS (Vehicle Speed Sensor) but the wire to tap in is sorta hidden. Still works none the less, just wont produce quarter mile times.

Anyways, heres a night show, enjoy, will post another when its day.

Say hello to my little friend!

 

I use to have the HKS type-1 turbo timer and I had it installed but my speed display was not accurate at all.
I tried doing the calibration procedure but the speed was still off by about 15 kph
The rpm's were showing only 1/2 which is normal.

Let us know if yours works accurately

 

Will do pacific. Will be doing that while putting my Dad's lift kit on his jeep

I am hoping its going to work fine. On the VSS which wire did you tap into? I havent yet looked at the Sensor.

 

I had a diagram of the ECM pinouts from a thread on here. Can't find it but it's here somewhere
There was a yellow and purple wire (Low reference, High reference)
It comes from the trans. to the ECM but be careful because the ECM has many yellow and purple wires in those 2 huge harnesses

 

My turbo timer only has 1 wire to go to the VSS. Should I go to high reference or low then?

 

which greddy turbo timer is it?
