Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

I get that on a 2 mile trip to the store. Are your trips super short? What’s your tank average?

 

That's my tank average, with about 1/2 tank. Yes, they've been short this week. Still, I used to get 17 doing the same travel routine.

 

Man I get the same gas mileage what size tires do you have?

 

I got another 200 miles on b04 91 octane, stock limited. I had a 15+ mph cross wind that I know I'd have been in 5th the entire time at 70 mph, 1.05 I was in 6th and even pulled most hills in 6th. Yay! More useable on the highway, just as OV said. I avg 19.7 mpg (wind was negligible on return trip home). (Winter blend gas too). Nice work Mat. No issue with 4th hanging for me.

 

I'm curious if that 12mpg has a faulty thermostat? does it get up to temp?

 

Man, I wish it was something simple. It was up to temp today. I guess I'll pay attention to that.

 

Lift, 275/70/17, roof rack, leer shell

 

Is the truck nose-high? After I switched from Icon to Fox, I spent a few weeks with way too much preload on the front coilovers and was up 3.25” in the front and 1.5” in the rear. I thought they’d settle - they never did. Even though it looked level “see picture” I reduced the preload to get 2” up front.
I made weekly trips of 300 miles from Maine to Rhode Island for the better part of a year averaging 18.2 mpg. During the weeks I was nose-high, I logged 14.2 routinely and could feel a lot more drag. Just a thought.

3.25”

2”

 

12 MPG will be the straw that breaks my camels balls and sends me straight into the arms of a Tundra....
before they frigg that up too attempting to conform to "regulations" !

 

I get better mileage with my duramax running 65mph through the mountains grossing 20,000 lbs. cat scales certified

 

I'm running like 3.75" with a slight rake, back is like 1/2" taller.

 

Like many, 1.05 is my last hope.

 

I agree it’s sometimes easy to overlook some deficiencies, but if you’re cross shopping the Tacoma with a 2500HD, one of them definitely isn’t for you.

 

just go like i did. have both

 

Hah! Tacoma at work.

 

Your mileage decrease followed the addition of a shell right? Easy experiment, drop the front 3/4” for a week. +3.75 is going to cause you a lot of problems in the long run anyway: ball joints, steering gear, etc.

 

The ONLY thing that changed was the shell and 1.04 -> 1.04r. I honestly thought the shell would give better mpg, not worse. I'm waiting to see what 1.05 yields. I never had a problem with the suspension before. My back is like .5" taller than the rear now.

 

I'm just going to throw this out there, not that your issue has to do with this at all, I don't have any idea there, but:

Only make one change at a time. Measure it's impact, and set a new baseline. If you do more than one thing at a time and something goes wrong, you don't know what to troubleshoot.

This applies to just about everything in life, imo.

Merry Christmas all!

 

It should be easy enough to test - just reflash to 1.04 for a tank and see if mileage improves.

 

Yeah, both true. We're so close to 1.05 i'm just gonna wait. After that I'll start trouble shooting.
MERRY CHRISTMAS
