vF Tuner for the 3.5L Tacoma

Been gone for awhile. Has all ecu been released on vf tune software?

 

that's great...

For an eco friendly shift pattern I would recommend trying the following: lower your down shifts on 3-4, 4-5, 5-6 by *95 maybe *90. Leave the two lowest values alone on each map. Upshifts: 3-4 try increasing by *105, and 4-5, 5-6 *105-*110. If you can get your rig to hold 1200 - 1500 rpms for the speeds you drive most often, I believe it will benefit your mileage considerably. Lugging around at 900-1000 rps is no good. Keep an eye on your downshifts though. If it holds the gear too long, you're gonna be dumping in the fuel at low rpm. It's gonna be a delicate balance of reduced gear hunting but avoid the lugging. Most of your mileage increase is going to come from your upshifts being increased. The downshifts being lowered will only really help with gear hunting. My 2 cents.

 

Thanks man.

Will test with my friend's truck.

 

Also consider NOT having increased throttle sensitivity. After all, that's what's telling your truck to add fuel. A number pedal often goes hand in hand with exo friendly driving.

 

I’ve scrapped the idea in favor of gear lock for now. I’m just focusing on making my truck run good and smooth in D.

Similar to the reported experiences with FO maps, most every change I make for better performance either increases or has no effect on my real world mileage. For the simple reason that I need to floor the skinny pedal less often.

I don’t doubt my “EPA certified” mileage is down, but I drive in the real world.

 

@Mooseditty17, not complaining about 2.0, that's still a stock tune. But liking how your tune works in my truck, I wasn't sure how the shift points would be for me because I'm on 30.6" tires & your tune is 33". But working good so far, holds gears better for me, shifts feel like where I would expect. Looking forward to seeing what you do with the 1st gear throttle. Any chance I could call the dealer & tell them to get your truck back to you ASAP? Lol Good work, thanks

 

Right now I am driving on my optimal tune, which is called Chill_ECThighride_nonlinearenhancedthrottle

So... Yeah I think I had a couple minor changes to downshift points (I think there were one or two I brought up), increased upshifts. I found that this and, depending the driving conditions gave me the best bang for my buck. It's also super smooth. I'm getting better on the hwy, but around town slightly under what 2.0 was giving me. So maybe it would be worth exploring like an intown cruising shift set? I don't know how much of an effect that TC partial unlock was actually having on mpgs either.

 

I saw yours progress on tbe tune and your graphs. Should you be able to see a similar response in TS?

 

Not sure i haven't figured ts logging out and it's slow as hell to open

Mine wasn't working, sent the info to Mat and he said there should be an update shortly that fixes it.

 

Hey, Folks.

2019 and 2020 AT TSB (Canuck style) has dropped. Updating the ECU Update thread 1st Post in a moment.

 

If it's the around town, try raising upshifts in 1-2,2-3 and 3-4 upshift a little. Maintain 1200 or more rpm whenever possible. 1500 even seems good yet. Watch that current mileage bar.

 

I think I have finally got my truck running the way I’ve always wanted! Going to take a break from VF and enjoy it! I’ll check back every now and then to see if there’s any new improvements so keep on keepin’ on! Shoutout to all you guys for the help!

 

Edit: drive around in SMode. Pay attention to your current mileage bar. Set Primary shifts based on how much higher or lower you choose to shift over what it currently shifts.

 

This with the latest tune you shared a few pages back? Or newer version? May be putting your tune in a friends truck.

 

Yeah the rev5.5 one

 

Go to vf logger and note how many PIDs available. Start the engine and note how many left.Try select Relative accelerator position and then start the engine. See what happens with this PID after that.

 

The current PIDS it gives after connecting is the supported SAE PIDs.

We are working on our logger which will include all techstream PIDs.

 

Np. I figured that it is the case.
So the VF commanded throttle actuator and throttle position = Toyota's throttle motor duty ration.
Relative throttle postion= Toyota's throttle sensor position, which is 0 at idle. Correct?
It would be nice to get accelerator position working, cause this is where I see quite a difference
