In prep for the GTS timing belt/gears/wp project I began taking some peripheral components off and when I moved the front wiring harness discovered a disconnected 3 prong connector. Tracing back it is the connector for the hall sensor.

IIRC the hall sensor retards ignition timing but dont recall by how much or any long term issues that may have occurred by running disconnected?

Another add to the winter projects

Wow..ya..youre missing a good dose of umph with that missing.

6d retarded across the board.

thx Speed...........just found the write up in the '87 MY Technik

any comment re the long term running with the hall disconnected?

Given where I found the connector end its been this way for a long while.

Speedtoys

The ECU cant tell WHICH cylinder had a knock, so pulls back timing on all to be safe(er).

Should be it.

Its just a "who did it" sensor.

.....and with the winter battery disconnect the EZK eprom will forget all past issues and be of sane mind come spring

Just plug it back in and go for a drive. Cold weather and a properly running GTS = lots of fun.

the flyin' scotsman

I would Sean but whoever left it disconnected did so 'cause they busted the HS connector......another add to the Roger list

need snow tyres to drive...........maybe the truck wheels would fit?

Pansy, I drove to Edmonton one winter in an 87 auto with summer tires. I had no problems.

They don't make 295/30/18 mudders up there?

*****, we drove from Craig, Colo to I-80 in Wyoming on Co-13/Wyo-789 (along the continental divide) in a full-on blizzard last winter, the locals were all in the ditches and we had to drive around the gates at the interstate.
(Oh yeah, and we were in the Audi all-road with snows).

Malcom, the EZK resets its 6-deg retard whenever the key is off. So just replace the hall sensor (and a new harness connector if needed) and start the car...
And check it with that Sharktuner that you are allegedly partners in, if you can get your hands on it!

thx Jim........if only I could get out the driveway

The harness connector looks good just got some residual broken conector from the hall sender. I'll replace the sender, spark it up in the spring and enjoy the new found +ve timing.

I saw the ST once but I need another set of PEMs for the GTS then perhaps it'll reappear?

Sorry Jim, you're the *****, snow tires and all wheel drive really? You could get away with calling me something if you were on a motorcycle......
I have ridden a Kawi ninja zx6r in the winter with slush.....

I have a spare HS that came off the S4......any bench tests to verify operation?

Lizard928

If you have an oscilloscope, and +5V power supply, then you might be able to test it. Or just install......
