Hi,

I have a MS-II v.3.0 software v.2.905.

I was running my engine the other day, trying to get the idle, timing, etc. squared away, and it started running a little hot because I didn't have my cooling fans working correctly. I was concentrating on the coolant temperature reading from my MS on Tuner Studio, it was reading at 215F. I have two other analog gauges on my truck for a backup reading, I happened to glance at them and they were both showing a temperature of 250F. So it got a little too hot on me while I was watching the TS gauges.

Can anyone think of a reason my TS gauge would max out a 215? The sender I'm using is the GM sender from DIY Auotune. I've tried recalibrating the Themistor table, but it didn't seem to change anything. I plugged my Stimulator in and turned the coolant temp up and got a reading all the way up to 245 in Tuner Studio.

The fact that TS will show a high reading with the Stim connected leads me to believe something is wrong with my sender, but it is new. Does anyone else have any theories?

Thanks!

Check to make sure you have "Expanded_CLT_TEMP" activated under Project Properties.

Thank you Matt. I definitely do not have that activated. Searching through TS, I noticed that, but couldn't ever find anywhere that said what it was, or what I should set it to, etc. I'm 99% sure it's off on my setup. Hopefully that will solve the problem. Thank You!

Edit: I did find where it talked about it in the MegaManual, but I thought it was for high-temperature cases such as an air-cooled setup. I wasn't sure if it pertained to me. I also wasn't sure why it would work with my stim, but not on the actual vehicle. I just mostly wanted to make sure I didn't have a problem somewhere.
