OK good to know, thanks. So I guess I'll either clamp something around there very tight somehow (I'm not too crazy about soldering haha) or I'll move it to the stock location and leave the stock one disconnected. Thanks!

You should be able to change the resolution on the EGT to read four digits before the decimal. It's cumbersume using the one button to control everything on those SPA gauges.

So what do they start doing when they wear out, reading funny and all or what? When I first put the water temp sensor in and first started running the car (just got a rebuild recently) it would jump around a lot in temp and then land on 318*C and stay there...I was sure that wasn't right. So I burped the system several times with a Lisle funnel and now it works about 98% of the time without jumping around or staying at 318*, even not being grounded. But if the manual says it needs to be grounded that's what I'm going to do.
I thought I read something about changing the resolution or something on the EGT gauge but I still need to look through the manual again. I agree, that single button is kind of a pain lol. Thanks!
