But if AUX input gauge shows temp change, surely that part must be OK?

Anyway, I should measure voltage change at AUX pin (and ground) on the board? Nothing there. It reads 0.00V. But I just heated temp sensor from a room temperature to the body temperature. AUX input gauge went from 60 to 47.

I do not have running hardware, but I can confirm that I still have the same problem with user configurable outputs. Gauge shows temperature changes, but outputs do not change from ON to OFF (and back) at preset values.

Nice, thank you.

Can you post few photos?

That was my idea too, but I was told that it probably would not work, that I'll probably need to add another sensor. BTW, did you try to connect temp sensor to MJLJ? Can you reproduce my problem? Or is it working as it should? I again downloaded both tuning software and controller firmware, flashed ...

From the second link:

"The Direct Ignition System (DIS) uses either a magnetic crankshaft sensor, camshaft position sensor, or both, to determine crankshaft position and engine speed."

Why do you need camshaft position sensor to determine crankshaft position and engine speed?

... In a traditional distributor-equipped engine, the crankshaft turns the camshaft through a chain or belt, and the camshaft incorporates a gear that engages and turns the distributor shaft... In the case of Megajolt with Ford EDIS components, piston position is sensed directly off the crankshaft ...

Here is screen recording of what I did (I prepared it in Linux, so I hope that you can watch it in winblows, it's DivX file): http://www.ptt.rs/korisnici/i/v/ivica/slike/demo.avi 15.01.09 - I did some editing on the original file, and added another version to youtube: http://www.youtube.com/watch?v=...

I just remembered to test if configurable output works when I set it to load (mjlj is in my room, so I could not test it with rpm), and it works exactly as it should.

So it seems that it does not work only when set to "aux".

I made calibration file with Easy Therm: http://www.msefi.com/viewtopic.php?t=10308 After you install run it, choose Celsius or Fahrenheit, measure sensors resistance at three temperatures (easiest is at freezing point, body (or room) temperature, and boiling point), and press calculate. At c:\Progr...

OK, I finished calibration for mu temp sensor (BMW OE: 12 62 1 710 511). If someone else needs it I attached configuration file. So, now my aux input gauge displays degrees Celsius, but I still have the problem with user configurable outputs. None is switching on and off at preset activation point. ...

I then dipped temp sensor in a cup of cold water with ice (0 Celsius or 32 Fahrenheit) and gauge showed 60. At body temperature (36 Celsius or 97 Fahrenheit) gauge reads 20, and at boiling point (100 Celsius or 212 Fahrenheit) gauge reads 2. Do I have some reverse resistance temp sensor, or what is ...

I connected my spare temp sensor to MJLJ aux input. I first made slight modification, and soldered parts for AUX signal conditioning circuit directly to MJLJ board (as I not use TPS option). Here is the photo:

So for whatever you connect to aux input the gauge reads 0-255 (or 0-255x2 x3 x4)? 0-5V is also 0-255? You can not change this? Actually in my case it is not important as I just need to switch aux radiator fan on low at ~91 Celsius (I think), and on high at 99 Celsius. But it would be nice if the ga...

Another question. I downloaded and installed MJLJ Configurator V3.3.0 (and upgraded controller firmware). I added Aux Input Gauge, changed it's name to Coolant Temp, changed units to Celsius, but I am unable to change the numbers on the dial. I'd like it to be ~ -13 to + 115 or something. It seems t...
