Gq speedo adjustment

[patroltb42]

running 33's with 4.1 ratios. trial and error the first time only moved it a small amount anti clockwise and went out further so i went the other way a touch and got it spot on. had the car strapped on a hoist with rear whells off the ground, with my car 100kph by gps in 5th gear it was doing 2100rpm, while car was running i put in 5th gear then wound the idle up until it sat on 2200 and set the speedo at that. dont recomend you try this at home can be a bit of a danger on jack stands

Thanks.

Should be fine if you have the rear on stands and remove the rear wheels.

I came up with this idea for easier speedo adjustment. I drilled a hole through the cluster inline with the resistor. This way I can adjust it without having to dismantle the cluster. When adjustment is done, just put some sticky tape over the hole to stop dust getting in...

Notice the hole that I drilled into the white plastic housing..


Now I can adjust the potentiometer without dismantling the cluster...


I have turned the pot a few degrees clockwise, and test it soon...

Was it confirmed that it doesnt fix
The odo?

It didn't have any affect on the ODO. I'm not too fussed as the ODO and Speedo were each out by different percentage. I really only use the ODO for maintenance schedules and can easily calculate the actual values.

Either way I look at it, adjusting the variable resistor is a very easy fix for the speedo. It only needed about 20 degrees in the clockwise direction, for 33" tires.
