Hmm, alright - I will try on one of the clusters, to use my original coding plug, run the cluster test and align the miles, and if that screws up the tach,I would just do the mileage advance with the second cluster.
I think I would just time it and send it the signal continuously for a period of time, to climb about 500 miles, taking a break afterwards, and loop it over, based on exactly how long it would take at maximum speed that it would take.
I'll see if it's possible to send it a higher value and just run it as-is, stopping maybe around 160k, to slow down and get it to the exact number slowly.
Thanks again! I'll try to post something here tomorrow or the day after
