vF Tuner for the 3.5L Tacoma-AGM tuning

?

 

For the 2020 and above "Yes" at this time.... The VFtuner has a limited amount of tables for adjustment, but this might change in future releases / updated of VFT.. Looks like the lower years (2018 and below have a bunch of other tables to play with.

 

If you look at the 2020 Alternator Tables in posts above you will see that they are very limited compared to 2018 and below. Some of us are hopeful that with future releases we might get more access.

That's all I'm saying.


Having said that, I've gotten great results with only making the changes I've made with limited access to the tables everyone else has (2018 and below)...


Thanks,

we need non-blurry screenshots.
I am happy to supply mine, but I just edited the main first table/graph.

I’ve been holding solid from 14.4(+/-0.2) to 14.6(+/-0.2) during all cycles and shifting only drops to a min of 14.2(+/-0.2)

I also just edited the first table and added 4 (%) for temps up to 60 and 5 (%) to temps beyond. That actually makes some sense since we are targeting voltages about 5% over what it puts out stock. I didn’t change any of the other values and am reading 14.4-14.6 consistently at the cigarette outlet which I confirmed exactly matches my terminal voltage with a multimeter. I do see occasional fluctuations when coming to a stop down in the 13’s but it comes right back up so it doesn’t concern me whatsoever. This is on 04A61.

 

I get those short fluctuations in the 13's as well, but it's only for a few seconds

 

Here are my exact 0A461 values for anyone that is interested.



FYI for those of you taking pictures of your computer screen with your phone (looking at you @RangerComa ), use the shortcut: Win (Windows key) + Shift + S to open the screenshot/snipping tool and select the section of the screen you want to capture. It will automatically copy it to your clipboard and you can just paste it directly in your post.

 

Thanks for the great info! Did you say which battery your using? I am also 04A61

 

I didn't. Northstar 27F. Also - It's about 40-65 *F where I am right now so I have no experience with these numbers at actual cold temps

 

What about the rest of the tables? Unless I missed a previous post

 

Didn't touch 'em.

 

Have you logged yet?

 

I haven't, just been monitoring real time. TBH, don't know how to log or what to use. I looked at the VF tuner logging but it looked like it didn't track voltage. Happy to do it though if you can give some guidance.

 

Shit I can't remember what value it was under off the top of my head but I monitored in real time and didn't log, but saw the option to do so.

Just memorized the numbers for when I reported my findings as I was driving

 

Haha sounds like my logging as well . At the outlet I'm seeing 14.4-14.6V pretty consistently. I also verified my outlet meter matches the terminal voltage. (At least for the one time I measured it!)

I don't have a ton of miles on it yet but should be driving it more soon and will report back.

 

There's a pid for it a little more than halfway down the list in the vf logger....control module voltage or something similar.

 

Good memory. Found it!

 

Taking @Boltripper 's guidance and made those adjustments to a tune from Mooseditty.

I'm running a

Odyssey 34R-PC1500T. According to ODB Fusion it was sitting at 14.6 idling in my driveway. I'll monitor it on my commute to and from work tomorrow but it seems good!
