Cool. I take it you are piping this into the MS3? I need to figure out how to do this, I'd love to be able to log oil temps, and set a rev limit for low oil temp.

M-Tuned Reroute 1.8 Master Race here, I have a pre thermostat 1/8" NPT port for a sender, I just need a gauge that does not suck.

Or a sender that does not suck. Or whatever. **** just needs to work because I'm tired of ******* with it.

 

See post above yours.

Also interested in 200c engine temp.

 

Yes. Along with pressure. And probably fuel pressure. And hopefully EGT. And knock. Etc.

Then going to try and setup a warning light and a failsafe. Need to set the revlimiter to 0 and see what happens though.

Oh and will be using this: http://jbperf.com/io_extender/tinyIOx.html to connect everything.

 

We decided on 30ft/lbs for the aluminum brackets right?

That's within 3 thou of the design, or .413.

Was it 33, or 36? I went to 45 at least three times on one bracket and it's still holding fine.

33-38ftlbs is good, and is around "spec" for a 3/8-16.

Pretty ridiculous way to do it. But might be necessary.

Westfield is a boss.

 

Idk what to tell you. You saw all my measurements. Maybe my rotors are weird?

 

Might be necessary?

Make it blink the light and shut it off when it's safe, why not do that? The car randomly shutting off dependent on all that seems rather foolish.

 

Because the main one is going to be oil pressure. Which you can't see a light and react to quick enough.

 

I'll grab some feeler gauges tomorrow and see if my calipers are centered. If they are I'm not sure what to do, other than run the washers or make brackets with the right offset, hope they're just special for you when it comes to Rallas and Sean...

you could measure the rotor if you want, you'll need to lay a straightedge or something across it and comp the difference with the caliper, if that makes any sense. It should be this..

 

Don't use much more than 30 ftlb. I found these to strip fairly consistently at 40-45ftlb. 30 is more than tight enough and makes sure you don't strip anything.

That measurement should be almost perfectly centered.

 

It isn't :(

What else should I measure? Rotor?

 

Those were new pads right?

 

Brand new. But the uncentered gap was between the caliper and rotor. Brake pads didn't matter.

 

Oo, that's really cool. I wonder if its possible to use that and the wideband CAN module I'm using now with my MS3-B?

 

Yep. It should can is cool like that.

 

Download source, hack source, compile, flash, done.

I have considered it. I don't want to deal with updates though. I kinda like Westfield's idea.

 

If you were talking about major surgery I'd agree, but a simple check to see if pressure/temperature are over some critical threshold is trivial, you just insert a single function call into the main loop. That's way better than some external hackery.

Re-merging your changes isn't even all that hard if you use a simple revision control system. Check in the base code, pull a branch for your changes, check them back in. When the new release comes out, you check that into the mainline, then merge it down to your branch.

Back in my undergrad days, I never understood the value to source code control, even in the classes where they tried to get us to use it. A few years later I was taking some grad classes at Stanford (was thinking about getting a master's part time) and the first thing I did when working on a programming assignment was to create a CVS repository.

CVS...ew.

Have you messed with the code? Getting the build chain set up is the most annoying/time consuming. I'll look into it at some point.
