Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

That was the build Mat dropped around 8/7/19. You would have had to have snagged it from his site before he took it down with newer builds.

 

I can't think of a scenario where gear lock makes sense. The current S mode can accomplish the same. I can limit to 1st gear if I want, then choose when 2nd is allowed. Why not just allow it at high RPMs so it can shift where you want, meaning bump it up to allow the next gear.

There is no practical reason you would want to block out a downshift I wouldn't think. Too low of RPM and you would have to downshift so if I'm in S4, I'll let the truck do it if it begins to lug. If I want 3rd gear I just bump down to third to block out 4th and bump back to 4th when I want it back.

I suppose I'm resistant to gear lock because of how I drive. Personal annoyance to lose speed on a hill before the truck finally downshifts. I drop it to s5 to go up hills and go back to s6 when I'm flat again. I don't want to manually have to shift through all of the lower gears to be able to keep my highway driving procedure.

 

I tried it the other day and did not see it lock. I’ll try again today

 

Dont use a gearlock tune then

I use it all the time offroading and rock crawling. Works great for that

 

I think that’s the end goal

 

I'm hoping we don't stuck being forced to have it in S mode.

How do you use it offroad? Can you give some examples? I'm curious.

 

With where these tunes are now, I agree with you 100%. There was a time though when our trucks would downshift unnecessarily. I think that’s where the push for gear lock originated.

Now, it just seems that people like the ability to shift an auto for shifting sake??

 

I forget which beta I'm on, I think an OLE one. But I agree. Prior to OvTune, I would end up having the going up hill, losing speed, press pedal more, drop to 4th thing and race up the hill. I can stay in 5th now and do just fine. Haven't been to the mountains yet so I'm sure that might different.

 

It holds the gear I want at that specific time better than just sequential mode by itself. less downshifting.

Ive also used it on the highways to hold 5 when in some hilly areas.


Also, all the 2.0 tunes are beta and Mat has said that they only contain portions of what will be in the non-beta release. Im quite certain he will drop a 2.0 tune without gearlock for those who dont want it.

 

I just wish when charging down the highway in D and obviously in a higher gear than 4th, when shifting into S to not have the transmission drop down to 4th automatically. The transmission should stay in the gear your in while driving in D

 

The issue I’m having now is that my truck doesn’t shift to 4th anymore when it needs to. I am running 4:88’s and the senseless down shifting was much better. Hopefully they can come up with an “in-between” to satisfy everyone

 

I habitually shift to s5 to start driving. Use it in town and change to s6 on flat interstate.

 

I guess I could see that. I don't do anything offroad (probably will in the future) and I figure if s5 won't get it done on the highway and the truck wants 4th, knock yourself out.

 

My truck is heavy with armor and all so if it's downshifting a lot, I'll use the gear lock on the highway too.

2.0 has been pretty awesome for my truck so far.

Im flashing back to the 87 0944 4.88 tune rn

 

Different circumstances between us then. I get that. I want to do 4.88s at some point too.

 

It was the first drop of the 2.0 beta tunes as ^ stated - not sure if there were other tunes associated with 0944 as I think it was specific to 4.88 gearing. It there were other 0944 non-4.88 tunes released and if they are as good as the 4.88 tune I would think any 04B04 owner would be equally pleased.

 

You obviously don't tow much or go off road. Gearlock is a good way to control the constantly shifts between 3rd to 4th and back to 3rd when trying to tow. If this transmission wasn't so spazdic I agree it wouldn't be needed.

 

Gearlock has and will always be optional.....

 

Let’s talk about the scenario you’ve described... You’re towing and the truck bounces between 3rd and 4th. The logical thing to do would be to lock it in 3rd because it would be lugging in 4th. We know that to be true because by downshifting, your transmission is telling you so.

The question then is why “lock” it in 3rd with the gear lock feature instead of simply “limiting” it to 3rd with the standard feature?

I’m not trying to stir things up here. This is a genuine question as I tow about 3000 pounds 2-3 times a month.

I also off-road very regularly... nothing that I would consider technical, but I’m sure others would. It seems to me that if the truck is put on a technical line/approach, you’d probably be driving pretty slow... probably even in 4lo. That means it’s not downshifting all all. This may be just me but if I’m concerned about being thrown off a line by a downshift, I’m probably going to fast.

I should add that I live in Sierra Nevada... lots of hills, mountains, snow, ice. I say this to show where I’m coming from with my opinion.

 

The issue would come up where you limit it to 3rd, and then it downshifts on it's own to 2nd. Or you limit to 4th, and it will downshift into 3rd.
The point of gearlocking was to stop the truck from automatically downshifting in S mode when you go high throttle. The truck already has an automatic upshift limiter... which is S mode.

Without it you cannot stop the truck from picking any gear it wants that is LOWER than the limit gear in S (say you go S5... truck can pick any gear it wants lower than S5. 4,3,2,1 depending on throttle position).
