Speedometer Recalibration

A few days ago I recently picked up a white face gauge cluster to complete my interior. I did the odometer swap, but accidentally left out the step to calibrate your speedo before you remove the needle. How should I go about recalibrating it.

Unfortunately, he already swapped the clusters. The AA battery test only works when the original needle is still on the cluster. Once the needle is removed the gear MAY go back further then the original placement.

Easiest way to do it now is remove the plastic cover and the needle, get a friend to go out with you and pace in another vehicle. Once a constant speed is reached, jam the needle on. Then test at different pace speed intervals.

I knew where my RPM's and sound of the truck at 80 km/h was, so I jammed the needle on. I got my bro to pace test at 40km/h, 60km/h , 80km/h, and 100km/h. I was on the money.

One piece of advice, do this on a long straight section of unpopulated road. I did it on a paved back road while no other traffic was around.......just for safety.

If he used the same needle that came with his new cluster he can still use the battery test on the old cluster and match it to new one

I think will try to just pull the cover off and try to match it as close as I can to the speed on my scanguage. I am planning to get a X-cal tuner in the spring which supposedly you can recalibrate speedos with. I will try and match it as close as I can and then get it exact with the x-cal in the spring.

Sorry, I wasn't too clear in that.

He said he got a new gauge cluster and did the odometer swap, in which the speedo needle is removed in the process. Because he didn't perform the test on the new cluster prior to removing the speedo needle, there is no way to properly retest using this method because the original needle position was not recorded. He could have put the needle back on at 0 MPH, but having it exactly correct is very hard now.

The easiest way is for him "as he stated" is to put the needle back on while driving using his Scan gauge as a speed check.

Sorry about the clarity.
