OpenFlash Tablet and Vortech Supercharger

Hi guys,
Currently in Oxnard CA visiting Vortech Engineering. Spent a good part of the day working with their tuner on implementing the OFT on boosted BRZ. Great results. Will be spending some more time with them tomorrow and may hopefully have some news later this week that will hopefully satisfy all you OFT users hankering for boost!

More later :)

Cheers,
Shiv

Well this is the FI I want to purchase for my car so I am highly interested to see the results.

1st - Phantom ESC
2nd - Vortech

This road can only lead to Phantom + Vortech twin charge. Just so long as the Phantom doesn't become a restriction. I'm sure there is much more to this, but for now I can dream.

Am I right?

Do it! For science!

Shiv, if Innovate happens, I don't have to jump ship to swim to Ecutek... :)

Shiv, how do you decide what you're supplying tunes for? Is it basically driven by what people have asked you to tune already?

It basically boils down to what I have direct and sufficient access to. I can't comfortably make OTS tunes for FI kits through e-tuning. So it necessary to put a kit on one of our test vehicles. I also tend to choose kits that offer good fitment, value and manufacturer support to leave the door open for reselling to our OFT customers directly (with OFT dollar discount).

That's pretty awesome support!

Phantom ESC, please!

I agree 100% with this.

nice....

Will this lead the way for using the OFT with the Jackson Racing kit?

I'm very glad I just ordered OFT. The options for that tuning solution just keep growing. Thanks Shiv!!Acree, I think he already answered you in his earlier post. If he has access to a Jackson Racing kit (or Innovate kit for the others wondering about that, or any kit for that matter) on a car he can beta tune for a sufficient period of time it's possible this could happen. If not, then it's not possible.

Also sounds like he prefers to have a business partnership with the SC mfg if possible. Makes sense, from a business perspective.

I need basically a limp base map to get to the tuner. I was asking more about does this mean the OFT will be able to be tuned by aftermarket tuners on FI cars...?

I see. I think I know the answer (again), but I won't speculate for Shiv.

Phew... Got got back to the bay. But a 6hr drive with a Vortech SC'd BRZ isn't all that bad. I'll start a info-packed thread tomorrow that should be useful for those interested in adding boost to their OFT powered car :)

Looking forward to that thread, thanks for your hard work Shiv! I am very interested in OFT + KW kit

The OFT has been able to support this the entire time. Call any local tuner and ask if they support open source products. Although the datalogging is still lacking some things that a number of tuners would like to have. Your tuner should be able to provide you with a base map. Hell if he cant you know how to contact me and I may be able to give you a hand.

You would think that since all superchargers are dependent on engine rpm, the oft vortech tune should work for all the other sc kits with just minor tweaks

Its a tad more complicated than that. You don't simply just tune X fuel supply for X rpm. Typically our cars are tuned with a maf sensor. And in the case of say a jackson racing supercharger if you remove the catalytic converters in the car the MAF sensor maxes out at 5.0v and cannot read the additional fuel at higher RPM. Thus alternate techniques are required.

the big issue is logging. if you can't log fuel system status and injection mode, you can't effectively tune for larger injectors, which basically means you can't run anything that requires them. once those logging parameters are added you'll be good up to ~300-350whp or so when you run out of MAF and need speed density to keep going. as @nelsmar points out this is dependent on the size of the MAF housing, which in some cases (JR kit) is smaller and thus you'll hit that wall at a lower airflow level. of course you can increase the size of said housing, but that has it's own set of drawbacks.

it won't be long until you'll be able to run just about any supercharger setup with OFT, and i can't wait. it'll be a great option for guys who want to save some money on a nice bang-for-your-buck FI setup. i'd imagine it'll be a bit longer until we see the stuff available to safely run a turbo setup, though. hopefully that will be coming down the road as well. the two big things being provisions for a boost cut and electronic boost control, along with the aforementioned sd implementation for anyone running higher boost or e85.

things are looking rather exciting on the OFT side of things. can't wait to see what comes next. gotta love rapid development.

Quick update:

Spent much of this week on the dyno. Both at Vortech and at the local shop. And both dynos are Mustang Dynos. I'm quite happy with the result so far. They aren't final until we get the car on a Dynojet and get apples-to-apples numbers. So mum is the word for now :)

Our customer test car has a Vortech SC, OFT, OFH and Perrin CBE. It's a wonderful driving combo.

And here's a datalog form the drive home. Nice cool 50F night! A few 4th, 5th and 6th gear pulls :)

MAF voltage peaks at 4.8v. Boost level is just over 10psi. MAF housing is bigger than stock with absolutely no drivability/idle issues. All tuning/logging during calibration was done exclusively with OFT. Next week I'll have a very big update for you guys :)

Have a great weekend!
Cheers,

Shiv, I'm interested in going with this same combo. Any chance you have a video that shows how it sounds? I've already got the Vortech, The Perrin Header back (2.5") and just need the OFT and OFH.

What parameters will the OFT have for the twins?

Your question does not make very much sense. :(

Just clicked on the "buy" button on a vortech kit. Hopefully the tune will be out by the time I install it. 😃

Where did you buy it from? We will be selling the Vortech kit through our website next week. And will have discounts for new or current OFT users. Might want to wait and see what we offer :)

Could you send me a pm with the pricing? I was going to buy from ft86speedfactory today.

Not to mention different flow rates at the same boost pressure depending on the compressor used in the particular kit, different maf placement from kit to kit (changes the airflow pattern around the maf), etc etc. Different size charge pipes, inter-cooler efficiency etc. Though mainly the flow rate and maf placement.

download the maps and the software yourself and look at a stock rom.

+1
Vortech engineers spent a lot of time with MAF sensor placement and housing diameter. They ended up locating it in an enlarged intercooler pipe with sufficient straight section before and after the MAF element. Required a patch harness extension but paid off in the end.

That's the way it "should be". Especially when you show up at their Facility.

You can imagine what it's like when you're spending $15K-$20K on your GT3, and there is a line out the door. Figuratively of course.

I just realized I never quoted Shiv. I was talking about logging parameters since Shiv said it was tuned 100% logging with the OFT.

Should have pricing by Monday or Tuesday. Just working out numbers now :)

Ah got it. Just the same 12 channels that are curreu available with OFT logging. The next update will give the user up to 50 channels to choose from.

Someone let Shiv borrow their AVO/JDL turbo car so I don't have to buy the overpriced ecutek stuff. :) I can only dream...

You were effectively able to tune an FI kit with those parameters? Nice. I really can't wait for the extra ones to become available, and it is nice to see this platform as a whole progress.

I was asking about free OTS tunes, not custom paid tunes. Shiv's reply answered about free OTS tunes, which is what I was saying was awesome support.

Hi, my name is Eric and I'm a addicted to speed......:drool:

How did ur engine go?
