I have never seen this kind of trace before. I guess that if there is absolutely no input from the sensor, then it cannot update the delta-t unless it resets. Then once it resets it thinks it is zero RPM since there is no trigger. Kinda wierd that the trigger decides to work again for a while before ...

This is on my racebike, a V3 board, with MSII. Code is 2.862. The tach input is a geartooth sensor looking at a single reluctor nib on the stock rotor.

Have attached a lot file and the .msq I am presently running on.

If you take a look at the attached log file, at about 382 seconds the RPM ...

Thx for the pointer, I have sent mail to them asking about them. Looks like it might be a special order item.

I may just end up using the sensor that came with the thermostat housing, and try to remember to recalibrate when I burn code. Don't want to change the bias resistor.

I am redoing the cooling system on one of my racebikes, and need to replace the coolant temp sensor.

Ideally, it would be the standard GM temp curve that MS likes, and 1/8" NPT threads.

Anybody know of one that fits the bill?

Lots of searching on the forums/megamanual has turned up a 1/4" NPT ...
