Quick Question

Who makes the std Ultima gauges?
I need to calibrate my Motec dash so I need to talk to the manufacturer.

have you asked the factory, pretty sure that you are not the first one to run a MOTEC with the factory gauges, they probably know what you need need.

[MarkWebb]

Yes I have asked them. The answers I got did not help me.

[spatz]

you can do one thing, almost all temperature sensors work as a variable resistance, same true for gas level sensors. You could heat up water in ten degree steps insert the sensor and measure the resistance at the different temperatur levels. This would be your calibration data.
The other way to do it would be an on the fly calibration, if you run the MOTEC software I am sure it will allow you to monitor the values and just change your calibration data on the fly.
What do you actually want to do, drive the factory gauges from the MOTEC data ? I did not waste my time with this, just used seperate sensors for the Digidash, could you not use the sensors the factory is providing with the gauges ?

The sensors in the car are already connected to the motec dash. However they are not accurately calibrated. I was told that they were the sensors from the factory. I am trying to find out who made the sensors so I can get calibration data. I have already calibrated fuel senders and oil pressure but I wish to confirm the data from oil pressure. I have discovered that the oil pressure sensor in my car is made in taiwan!

[spatz]

ok now i understand, however the oil pressure of your engine should be a known value if it is using the regular internal oil pump, if it is an AS engine i would inquire with them and
let them tell you at what revs you can expect what oil pressure and use this for calibration
