When I translated to English the parameter files for PCHUD I had a problem with one of the temperature parameters.
It translated as either Engine temp. or Exhaust temp.
The readings were too low to be the exhaust temp. so went with Engine temp.
The problem is that i can't figure out what sensor is giving the data for this.

At one point i thought it might just be a mirror reading of the coolant temp. But the readings seem too different for this to be the case.

The only temperature sensors/ switches i can find are the fan switch attached to the left radiator and 2 on the thermostat housing.

According to the wiring diagram the sensor with the 2 pin connector goes to the ECU and gives us the data for the coolant temp parameter.

The other single wire sensor goes directly to the speedo, supplying the data for the " LCD heat bars"

Any ideas please :shrug:

I believe the engine temperature sensor is located at the bottom of the left radiator.

If the one on the radiator is the engine temp sensor then I need to determine which one is the thermostatic switch to turn on the fans that is shown on the circuit diagram.

I am beginning to wonder whether the circuit diagram is accurate :hmm:

I might be wrong, but I seem to remember the sensor on the bottom of the left radiator is supplied by U.S. Delphi, and it is the engine temperature sensor. :shrug: Perhaps perusing the following thread will help you to solve the mystery?

Hello.
I have cfmoto ATV Terralander X8.
I try connect to mt05 whit pchud.
But i get "com timeout error" on pchud.


I dont know what to do.

As usual, you are correct, Kat. ;)

The blue, 2-pin connector provides data to the ECU for engine temperature. The black wire feeds data to the digital dashboard, and powers the fuel bar display at the right side of the dashboard. The thermostat housing has an internal thermostat, which opens, and allows coolant flow when temperatures reach 70 degrees Celsius.

The thermal switch, which turns on the radiator fans, is located at the bottom of the left radiator.

It seems the mega download links in the OP are not working anymore. Would someone kindly share a working copy of the PCHUD software?

Thanks for confirming, spud:)

By the way , great job on your workshop manual tutorials, brilliant :tup:

The Mega website has pulled some of my files,
I have posted 2 new links on my profile visitor messages page ( click on the kat !) :tup:

Thanks for reposting the files, Katflap. And thanks to everyone (Katflap especially) for creating this great resource for RX3 owners!

Sorry for butting in...most of this thread is in a foreign language to me.

What software/scanning tool does CSC use? I read that they will loan it out if necessary.

Thank you, Kat.

I assume CSC is renting/loaning the Delphi Motor Scan Tool KF90121. Here is a link to eBay where one is selling for $400. :wtf:

Following the lead of Katflap, I bought the proper cable and run PCHud software on a laptop computer for a lot less money, and much more diagnostic power. :tup:

The engine warning light on the digital dashboard will flash DTC (diagnostic trouble codes). You can also buy several scan tools on Alibaba, or Taobao, which will communicate with the Delphi EFI system. However, those tools usually cost about $180.

I tried ordering the red cable today without luck. When I copy the URL into my taobaotrends shopping cart it doesnt load, remains blank. The Taobao ad list several as being in stock. I've order through taobaotrends before without a hitch so I'm puzzled by the failure this time.

You probably need to set your Taobao page to 'Mainland China.' ;) If you have more problems, contact your Taobao agent. He can help you correct the problem. :)
