Expanding coolant temp limits in MT for aircooled engines

msoultan · Post by **msoultan** » Mon Jun 25, 2007 10:22 am

Hey Eric,
Assuming I was able to work out any limits in the MS2Extra code, could MT work with a greater temp range like -40F to +500F? In other words, are all temp limits such as gauges and input boxes defined by the INI file or are there limits built into the software itself?

My goal is to put a menu option (or configurator option) that will allow the user to select between air-cooled and water-cooled and then adjust the various limits for input boxes accordingly.

Any guidance on this would be greatly appreciated!

Thanks!
Mike

Mike,

MegaTune uses the lookup table values from the thermfactor.inc file. If you generate a custom thermfactor.inc file that doesn't rail at 215 degF, then MegaTune will happily use it and display proper temps far beyond the MS limits.

sweeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet.

I'm going to adjust all the INI temp limits and compile my new coolant lookup table into MS2Extra. I'll letcha know how it goes!

Thanks for all your help!!

I just compiled in my new cltfactor.inc into the MS2Extra file and MT successfully reports temps up to 500F on the stim!!! woo hoo! For some odd reason, it doesn't go down to -40, but I'm guessing that might have to do with limitations of the stim.... further testing will iron out that stuff.

But yeah, MT seems to handle the temps ok. It was so neat when I saw it go up to 500!!

Now to start messing with all the inputs and stuff like that in the INI file.

cool cool cool cool! ... well.. actually.. hot hot hot!! haha!

thanks!
Mike

Mike,

It looks like you've got a handle on it, but we should still fix the calibration dialog in MT for those who don't want to rebuild the code from scratch.

Sounds good. Let me know if you need any help!

Mike,

Just added this to the 2.50 beta version:

Code: Select all

   [Defaults]
      genThermLoTemp = -200.0
      genThermHiTemp =  600.0

It should be out sometime after the 24th when I get home from CA and can compile it...

Hey Eric,
I just did some testing with temps that low and it really messes with the output of the algorithm. Realisticly, I think you're much more likely to see the higher temperatures than anything lower than -40. -40 to 600 fits nicely in the clt table output...

Where in CA are you?

Mike

Mike,

Ok, we'll fix the defaults before we publish them in the ini file...

I'm down in San Clemente at work for the week. I meant to ask where you were on Saturday? You should have popped over to Ontario for the meet at Spectre.

I totally would have, but I'm on a trip to Oregon to do some rafting for a week. Yes, let's talk about defaults as they need updating for the ms2extra side as well, so we might as well attack it all at once.

Let me know when you're ready and I'll do what I can to help out.

Thanks!
Mike

If people are reading this and want more info on my progress, let me know as I think I'm making some more headway on this project.

Mike, I'm VERY interested in what you're doing. I'm ussing micro squirt on an air cooled motorcycle, and plan to do many more once I get some of these issues figured out. Many aircooled motors out there that could benefit from affordable EFI.
Thanx

Mike,
I was just think about this just yesterday when i was tuning. Have you gotten it all resoved? I have a Baja with a 2275cc that I would like to monitor especialy when in the sand.
