I had been towing around 11k for almost and hour. It was 96 degrees outside and was around 2000' elevation. How do these number compare to you guys.

Exhaust temp was 850, boost was 12psi

Truck supposedly has a Superchips towing tune installed, straight piped exhaust and Ford AIS intake, stock height tires and 4.10 rear end.

 

Looks normal to me, but I didn't know 410s would run in that RPM range at 70 MPH.

A snapshot of the gauges is not unlike a photo vs. a video. Watching how the gauges move through the throttle range to WOT is more like a video... and very helpful when analyzing a truck's condition.

 

You think the rpms should be higher? Next time I've got the floor jack out I'll check the gear ratio.

What is your truck turning at 70mph?

 

I'm right at the 2000 RPM mark, but I have stock diameter tires.

 

I have a 4:10 rear end and 2250 is close to what I would be tacking at 70 (don't do 70 much pulling in CA). It's about 1750 at 55. EOT, trans temp and all but the Voltage is close to what I would get, but my voltage would be around 13.8 or 13.9.

 

oh yes, I almost forgot, I have stock tires as well.

 

I've always thought the voltage was a little low but it's running a dozen lights on the trailer and it also charges the trailer batteries through the 7 pin so I attributed the lower voltage to that, and the A/C was running on max.

 

check when your not pulling in the day. It should be closer to 14v. If not put a voltmeter on the battery on high idle and see if near 14v then.

 

Voltage looks ok to me for a fully charged battery. Here's a nearly 2 hour drive cycle. Starting EOT was 118 degrees. I assume the battery was fully charged from the previous drive.

This shows an initial charge to recover from starting and then some driving with a fully charged battery.

 

Looks good to me. About the same as my SG2 readings.
How did you get ECT to read with auto.

Same as Tugly I thought rpms low for 4.10. Maybe not

 

It was an Xgauge I installed and it worked. I heard it probly wouldn't work with my auto trans but I tried it anyways. I'll see if I wrote down which one.

Update: I think this is it

TXD: C410F1221139
RXF: 046205110639
RXD: 3008
MTH: 00010002007F
Name: ECT

Only thing is it reads funny until the temp gets close to around 127. It reads like double until then so it gets to like 254 and then switches to 127 and then climbs up to normal temps. It just proves how the factory gauges are just dummy lights with needles. When the dash needle reaches the middle (normal) the Scangauge is reading in the 130's and the needle doesn't move again until ECT reads close to 230. Same with trans temp.

Checked the rpm's at 70 mph today and it was at about 2240 give or take a few....4R100 in front of a 4.10

 

Towing numbers look good! What about MPGs? Smile per mile?

FYI ECT is not possible through the OBDII port on a AT. Sensor goes to dash only, not PCM.

 

Your numbers look like mine. I remember seeing 3.73 on them, but its been many beers since I looked.
