Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Yes, also let us know what that heavy flywheel does for you WRT low end...

BTW, are you ditching the accumulator while you're at it?

 

Nah, won’t be necessary according to Gadget at URD. Once the dual t-case happens, it’s gonna be amazing.

 

Technically, Sunday is the beginning of the week.

 

I wish I could get 93

 

Planned on posting it today, since I'm snowed in. Crazy amount of snow falling

 

Posting what?

 

I believe he is referring to updating his blog posts. See post 31407 in this thread.

oof.. hopefully that shit tracks more east than north! My forecast isn't showing anything nasty.. yet.

 

If you are going to correctc someone at least be correct..ISO 8601..Monday is the international standard for the first day of the week and OVTune is an international company....

Pretty sure he never stops working, kinda like an addict never really quits. He just works on the truck instead of handling tickets.

 

Yes it's regarding the blog.

Tonight the blog will be covering how ignition control works in this ECU, adjustments to octane, and what we have changed in 1.05.

So a sample of what we've done is below.

We know that controlling ignition, and ignition timing on this engine in general is quite pesky.
Well we've decided to completely rewrite the cables, change the code and hex to do so. ( we are also doing this with a few other tables to get better resolution).
Nearly 1/3 of the stock programming ignition tables are just for idle. It's such a waste of space, and limits how well ignition can be controlled when off idle.
The stock table even has cell range from 550 rpm to 570 rpm. It's honestly quite pointless, when even sitting at idle the RPM will fluctuate +/- 50 rpm. So rather than the ECU look up a new value it can retain the same value for this tiny fluctuation or rpm.

for example in this image is a *stock* ignition table, the area highlighted in blue is from 500 rpm to 1000 rpm. So much of the table is for this, when it cannot even used 90% of this tables area due to how quickly RPMs change from off idle.







So, we've rewrote the tables to make better sense, and give us much finer ignition tuning / resolution, as you can see below

 

areas circled in these images are before and after of "tune-able range" for ignition






We've also done this for valve timing tables and some others for 1.05

 

I don’t follow ISO. Sunday has been the first day of the week “forever”.

 

really looking forward to your feedback on that.

 

Trust me nobody on this list cares what you follow, but EVERYONE here who knows what ISO means are glad OVTune follows it...

 

Oh I know what ISO is, but Sunday is still the first day of the week. Get over it.

 

Who cares

 

Wow... why the heck did Toyota feel it necessary to micro manage idle - especially with ignition timing? Sometimes it makes me wonder if all this garbage was done to mask shit, rather than fix the problems they ran into. Doh

 

Guess this is why it bounces around so much at idle. Compressor goes on/off idle goes up down, turn the wheel idle goes up/down...

 

True that Moc. Band aid on band aid
