Lets Talk TORQUE (Pro)

[grumpy02]

Just got back from a trip to AZ. Some readings I got off my Torque app.
1) Trans Fluid Temp (TFT1) is always =/< TFT2. So is TFT1 the pan temp & TFT2 the T/C temp? What is an acceptable range for these?
2) CAT B1S1 is always = CAT B2S1. CAT B1S2 is always = CAT B2S2. Bank 1 is always < Bank 2. Is this right/normal? Seems like there should be some variation?
3) LTFT1 steady @ 2.34, LTFT2 steady @ 4.96 for entire trip out. During driving locally in AZ & for about 1/2 the trip home LTFT1 = 4.69, LTFT2 = 6.12. Then the values returned to previous readings. No noticeable change in MPG or performance. Ideas? Should I even care about the difference between the two banks?
4) What is an acceptable coolant range for a fully warmed engine? (at least 50 miles driven) I usually see between 180 - 195 F.
All readings from 07 4.0L SR5 4wd ~235,000 miles.
Thanks for reading

Wow, that's a lot of information for those who want to know all that stuff. For me if I wanted Torque I wouldn't have purchased a 4-Runner as it wouldn't be able to tow the things I need to tow. My 2024 is defiantly not a Torque Master and I wouldn't upgrade to a 2025 just to get maybe a little more, it still would lack in that torque range for me. Thanks for the info, I'm sure some will use it to their decission on if this vehicle will work for them.

I don't remember which one is which, but
Torque Converter temps will rise/fall quickly at hwy speeds when going up hill or overtaking. Once I figured that out, I re-labeled them so I wouldn't get them mixed up.
I've not figured out the CAT sensors, need more research to even begin to diagnose that.
Fuel Trims are a crap shoot depending on atmosphere/altitude and ethanol content.
But, I think those readings aren't outta spec. Once you get +/- 10% or more you have a lean or rich condition. I learned this one time with a vacuum leak and the fuel trims went to +15% to try and keep from being too lean.

I'm sure one, or more of the members on here know what's what with those readings, but in the meantime you might post them to an automotive diagnostician. On youtube there are a couple I would recommend: Rainman Ray, who has his own repair shop and posts videos all the time, and Ivan at Pine Hollow Auto Diagnostics who does the same, they are both skilled in those areas.

I have been using Torque Pro as well and noticed similar variations in fuel trims depending on altitude and fuel quality. It makes sense that the torque converter temp would be higher, especially during highway driving. Have you compared these readings in different driving conditions, like city traffic versus long highway trips? Also, has anyone here installed an additional transmission cooler on their 4Runner? I have been considering it and would love to hear if it makes a noticeable difference.
