OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

I'm talking final form, maybe a video walk around. Truck idling , panning over engine bay etc... Not dribs and drabs...

 

Yes please.

*Hyperventilating intensifies*

 

My engine bay still has a few beta parts on it.
But it will be shown off soon.

 

With the plan for continued 4lo/crawl datalogging, does that mean that the tunes are not quite finished yet?

I don't want to come off as that guy, I really am not trying to start anything here at all and I haven't in the 2.5 years I've been involved in the OVT threads, but are we waiting on more than just the dump tubes right now?

 

mainly I am doing additional testing, logging, verification, and any fine tuning that may still to be done.
I figured it would be a good idea, with these starting to ship soon I should go see if I can find any bugs. Over the last few days Ive just been doing a bunch of logging and testing *awkward* driving scenarios to see if any clean up is needed.

4low and 4high driving / offroading work fine. But I figured it's not a bad idea to verify everything.




Regarding what we are waiting on to ship
1. Downpipes
2. A few gaskets, which should be here before the downpipes
And a few small / misc things. However I posted before all of that is expected to be ready before the downpipes arrive.

 

Take your time and get it right....can't afford to have these 1st 25 be a disaster.

 

I think you need to prepare yourself for the need for tune adjustments once these are out in the wild.

Have you seen the sht show that is the OVTUNE development thread? Everyone is going to have a different experience.
I, for one, and many others have had a great experience. Kuddos to OVTUNE for trying to anticipate as much as they can, but they wont be able to anticipate everything

Also, us sideliners applaud you early adopters. But early adopting comes with risk, and that should be expected.

If it's smooth sailing, great. If it's not, don't be surprised. But OVTUNE will be along for the ride, and adjust as needed. Just as they have always done to date.

 

This was announced almost TWO fucking years ago. No offence but don’t hold your breath. OVtune is an R&D lab not a real company.

 

R&D takes time. You must not be aware of the other options on the market. Oh wait.. they are also in development

 

Yep that thread made me think to go test out weird driving situations.
Trying to anticipate weird scenarios the AT does.
Like "flooring it right when it shifts" ...

Normal around town driving, cruising, full throttle, all of that drives really nice and smooth.

But I know someone is just going to drive weird as hell and I have to make sure it drives well in weird situations.
Like flooring it, letting off, flooring it, letting off. Etc.


As far as out of boost driving - perfect
Part throttle boost - smooth
Shifting in boost - smooth, and holds boost post shift
Highway driving out of boost - perfect
Highway driving in boost - smooth, with one exception (which will come as a disclaimer. Don't lug it in gear lock in 6th under 1500 rpm with the TC locked. It will make full boost but doesn't feel great)
Full throttle boost - great, kept on the richer side for safety.
1rst gear - no possible way to get around traction control / throttle limiting. Tried everything.

 

Lol. Announced we were beginning development of it and it went through several changes. What a stupid comment.

We're a small company. Work slower. Don't have the budget of the big guys.
But we had boost in this engine before *anyone.* and are taking the necessary time to test situations, and try to break things just to see if it will.


I wonder if the other options on the market have..
1. Tested full boost to 7400 rpm
2. Tested offroad
3. Even testing 4high, 4low.
4. Tested in winter and summer
5. Trying to break things.
Etc

We want this to be perfect.

 

Just like everything else you “promise.” Looking forward to a production kit sometime in 2024

 

Thanks for the comment on this. This is one of the things I was watching.
Is there such a thing as gearing < stock ratio?, and more importantly, will that solve it?
I'm thinking the new found torque can lesser ratio gearing

 

**cough** troll **cough**

We forgot all the other people who have developed, fabricated parts, designed parts for fabrication, and tested fully..oh and tuned.

Keep your stupid insulting comments to yourself.

 

Yeah you bet, just hold your breath while we both wait.

 

when you say this disclaimer are you referring even to roll on throttle smoothly or WOT at or below 1500 rpms?

possibly both?

 

We aren't making this for the 4.0 so...

The issue is that when you floor it in 1rst, the ECU will only increase throttle over time.
So..like this
2000 rpm 30 percent
3000 rpm 40 percent
And so on.

I haven't found a way around it, but it's not really needed.
In my opinion.
Full boost comes in around 30-35 percent throttle.

In 5th/6th, full boost comes in around 20 percent under 2000 rpm.

So you're not "lacking power" in 1rst.

And FYI the tune will limit throttle too for torque control.

So unless you just want to do burnouts, I don't see a problem.

 

Mostly WOT / full boost.
Basically the disclaimer will be if you floor it in 6th, locked, under 1500 RPM the engine will feel rough.
Why? Lack of ignition timing.

Will it blow up?
No, I tested many many times to ensure it doesn't. Even as low as 1100 rpm in 6th, full throttle (engine struggles badly).

 

How Rude!

BURNOUTS!

 

I appreciate the effort and the response Mat. Again, I didn't want to come off negatively at all, sorry for sparking this recent shitshow of responses. I think I've demonstrated over the years that I don't seek to stir shit up over your work.

I'm hardly ignorant. I'm not unaware of the processes of R&D, I'm quite familiar with the other shitshow threads and have been since 2017, and am more than prepared for the inevitable tune adjustments because I have a MT, not an AT, and the turbo testing has been done on Mat's AT. He doesn't have a MT in the stable. So yes, I'm acutely aware that there will be work to be done and that there is risk to be accepted.
