vF Tuner for the 3.5L Tacoma

Does the compensation physically affect the throttle position? Per log you cannot see the throttle retard.

 

Gotcha. Always been curious on how the tow tunes will differ. Do you know of anywhere the different tunes (Standard, Performance, Towing) have been broken down and explained the differences?

 

My truck is a fat kit at heart

 

Not yet. The release notes will drop with the files.

You can do some reading about the 2.0 Final MTs tunes if you want:

My Taco hauls around the fat kid.

Although, I do laugh every time I pick up my bed storage bin. It keeps getting heavier. LoL!

 

I’d love to log some of the data and share. Let me just brush up on data logging and I’ll post results as soon as I have time to figure it out. Funny enough, If I slow down to the same speed I’d be turning at, but going straight- no hand on the wheel the truck has all the power it needs. I don’t fully buy the pump theory either at this point. My 1999 3.9 dodge Dakota could take a turn and power through it and it barely ran right and had a mostly seized kickdown cable and sloppy transmission. It of course had a hydraulic power steering pump too (lol) A much bigger looking one than the Tacoma does, fwiw.

 

It's dependent on what is actually going on, in most cases throttle is not reduced it is increased. Like when turning the wheel at idle, or to stabilize idle, etc.

There is a spot, specifically between....1200 and 1800 RPM where inverse calculated airload will not let you have the throttle you request.


I can post a tutorial how to eliminate this section where the ECU has additional torque reduction control.

 

Will there be additional tutorials on other tuning and engine processes so engine-illiterate ignoramooses like me can get smart?

 

I believe what you are tracking/seeing in your log is the actual input you are giving to the pedal, not the % that the throttle valve is actually open. Which is driven by many factors on this truck, not just pedal input as OV is alluding to. This looks like the case because your min% is 0 vs the 15-16% at the throttle valve that it would be when you are idling.

 

@Mooseditty17 I tried your file, changed to my tire size......nice work! I only have a few miles on it so far, but it definitely has a little more pep in the throttle.

 

I do log both accelerator, throttle + tranny's accel. from EFI.
I'm looking at the trend for accelerator, throttle and rpms. Two are rising, while rmps are dropping.
But you are correct, accelerator does not reflect the position of the throttle, especially in low rpms and loads below 60.%
Values for both are somewhat close around 80% of the load.
Here is previously posted thrend
Rpms 1665 1723 1355 1479 1629. 1782
Accel. 28. 28. 30. 33. 32. 30
Int. VVT. 27. 27 54. 57. 58. 41
Thr.Pos. 17. 18. 19 28. 19. 18
Load. 59. 60. 72. 77. 74. 65.
Speed. 13. 16. 18. 19. 22. 24

 

Tomorrow I'm bringing the Taco in for a possible timing chain gasket leak... Not impressed. How many of you would feel the need to flash back to stock because of going to a dealer? Will they notice a difference, yes. But will they really give a shit???? Magnusson Ferguson act protects us from warranty being voided as long as it's not proven to be the reason for claim. Better shifting and a touchy throttle can't be to blame for a gasket leak. Especially since it started before I flashed!

Thoughts??

 

I would not bother but a dealer will never see my rig on their property except when I come in to buy my oil filter elements.

 

That gasket leak fix is a pretty big job. Either pulling the motor or a complete front end tear down. For something that massive (not an oil change or diff howl), I might think about flashing to Stock. The leak is totally unrelated, but unless you have a really good feel for your dealer, I would probably play it safe.

Your Miles and Time from a DTC reset will be short. If they ask, just tell them that you pulled the battery cable while swapping a bulb somewhere. Any OBD app can reset the DTC counts.

 

Appreciate the input. Not looking forward to this visit...

No puddles, but a 3 year old truck shouldn't leak!!

 

They prolly won't give a shit, but it takes a minute to flash back to stock and not give them a reason to be dicks.

 

Also flash back if your tag says 'Mooseditty17', LOL

 

Google rulz!

 

That's not good.


As I have said, they really ought to come up with an external fix for this. Goop on JB Weld for all that I would care.

 

Unpopular opinion- Id rather a small oil leak than my whole engine being fucked with. Unless this timing cover leak gets really bad over time. Haven’t followed the issue enough to know how bad it gets...
