Torque app plus bluetooth adapter in my 100 (1 Viewer)

Fuel trim can be a valuable diagnostic tool - Eastern Manufacturing

monitoring it around town, stop and go, on and off throttle, high speed lift off and pedal pegged to get the most out of it. Short term at least, 30 minutes. It should be more of a one or two time thing just to verify. In an naturally aspirated car I would only monitor coolant and tranny temp, voltage, oil temp or pressure.
With so many lc and lx running around with the original fuel pump, fuel pressure regulator and other injection stuff it makes sense to look at it every once in a while just to see. All the 100 LC's and lx's should have replaced all that at least once by now at the ten year mark. Even the narrow band o2 sensors that last longer than the widebands. It's all going to fail at some point. I'm not into failure. IMHO trim is just another thing to look at to help out.

Great thread. Torque equations were always deemed to be above my pay grade, but you guys/gals have shed some light on that hack.

This is a resurrection. I have a 2005 lx 470 as well and used the codes you provided. Seems to be working for temp 1 but like you the temp 2 readings were pretty much everywhere. Did you manage to get a second temp reading or use one of the formulas later listed on the thread? Thanks

Ok guys I am hesitant to say I have figured it out but I did get at least 1 number fitting with what I would expect for the trans temp. I found this code for a 2005 Sienna and it appeared to work on my 2005 Lx470. Here is the scangauge code i used as well as the Torque codes I built using the calculator recs online. Let me know what these codes do and if they work.

I hope this works. I was reading 115 deg on sensor 1 and varying from 77 to 250 on sensor. Will have more info when driving later today. This was just trying in driveway after returning from church.

For reference: 2005 lx 470

I purchased Torque Pro to monitor trans temps for towing.
Obtaining PID codes are difficult for Torque Pro and are not readily available through hours of Google searches. I only found one that worked and it was on this thread. I attempted other codes specifically a tundra of the same year yet it did not work. Just wanted to share other formulas found but may work on different 100 series model yrs.

I'm using this :

I'm way behind most of you....... I have an 06 HDJ100R (100 series 1HD-FTE diesel) 5 speed manual. I've purchased the torque pro software and an adapter from Jaycar. The software is talking to the adapter but the adapter isn't talking to the ECU. I understand that in the States, since the 80's, all cars coming into the country must be OBDII compliant. In Australia, Toyota used M-OBD protocol until recently and I believe that the late 100 series was OBDII compliant truck. So why isn't the ECU talking????

I know it should be connecting/talking because other 100 series owners in Australia have them. Any suggestions???

Thanks for the insights.
