Normal operating temps for p38s.

Closed loop means that the O2 sensors are up to heat and working so the system uses them to adjust the amount of fuel.

Open loop operation uses the default values.

Just wondering where everyone is getting their temperature readings.

I assume from something plugged into the ODB port?

Yes, I get mine through the Torque app over ODBII using a PLX Kiwi adapter. Also from a generic ODBII scanner that plugs in.

I watched my live data on the way into work this morning, and it changed from Open Loop into Closed Loop at 74 deg C. Interestingly, my MAF is disconnected at the moment, and it is still going into closed loop. I thought that closed loop required O2 sensors and MAF, but obviously not.

X2 here with the Torque Pro App, but with one of the el cheapo Bluetooth OBD11 devices. I also have a permanent engine temperature alarm fitted. Like the one below on eBay

Mines a watchdog temp sensor

Mines on the nanocom. I've double checked with the thermocouple on the multimeter and the sensor is spot on.

That aussie desert radiator site sounds like it makes a difference. Basically the thermostate is almost closed.

I have both the nanocom and a watchdog and have noticed the watchdog temperature is usually a few degrees below the coolant temperature reported by the nanocom.

I will have a closer look on the weekend

So far I'm very impressed with the desert cooler, I've been working it hard on 4-5kms of soft sand but can't get it to break a sweat. It's running at 85 where as before it would of been over 100 and I'd be concerned and had to back off. I would like have a hot day to test it but the south coast of WA is cool at the moment.

Thanks heaps for that Hammer, I'd be very interested to hear how it goes on a hot day. Last time I was over your way it was 51 in the shade at Hyden the Fremantle doctor was nice that day!

Steve did you have yours in any hot weather?

I got my condenser fans running today!

I worked out the circuit configuration then checked the relays and the fuses and found that whoever replaced the fusebox some years ago (ahem :angel: ) had put F31's 30A fuse into one of the unused spots. You can't trust some cheap mechanics. :D

I still might fit a manual switch.
