Unitronic Flex Fuel

[ItalynStylion]

John, is there going to be a "track day" tune for those of us that want to run the Flex Fuel package on a circuit track and run E85 but only want the power of the 93 tune or similar? Idea being you get the headroom of running a higher octane fuel at a lower power and boost setting so you aren't flogging the car on the ragged edge all day long.

This would be great!

I knew I would get some comments about the pre turbo injection. Years ago, this would have been an issue. With new nozzles, pumps with check valves, this is nearly bulletproof. We're not talking some junk Snow Performance systems here though, we're talking systems designed to support 4,000HP drag cars. The newer systems with check valves right at the nozzle nearly eliminate all larger droplet sized mix being pulled into the compressor. The mist is so fine that everything evaporates right at the compressor side before having the chance to cause any damages. This is actually so effective that it is banned as a spray method in a lot of organized racing events, hence why some have changed to spraying directly into the side of the actual compressor housing itself.

Since it is public info now, these new nozzles are going to knock your socks off. THESE nozzles… are methanol injection.

You will spray the turbo fins on the intake side before the IC? Thats news to me.
Never done w/m personally but have always seen it around the IC area

It's very popular especially in the world of huge horse power.

I'll have to trust that you know the risks associated with that sort of injection strategy and have fabricated a nozzle holder that allows for injection right on the compressor nut to avoid blade tip erosion. I would be curious if the nozzle holder's flow restriction and subsequent efficiency loss would outweigh the potential benefit of the pre-comp. injection.

When installed improperly there is definitely a lot of risk, for sure. The newer nozzles spray such an insanely fine mist, you could spray anywhere pre turbo and it'll still mix perfectly. Tons of research on the web about pre compressor injection and the huge perks and benefits from it. I think you would really enjoy talking to Rodney at Pro Meth about it, you should call and ask about it. He's local to me so I stop by his shop once in a while to pick up my goods. I'm spraying pre turbo to essentially increase the size of the compressor housing, reduce spool times even greater, and keep cooler up on the top end of a pull. Most importantly, this has always been good for extra MPH at the track.

For RS3 the usual setup for Water meth is sprayed in the lower tube after the intercooler or via throttle body spacer. Billet intake manifold with jet in each runner might be available too but I sincerely doubt it.

I don't know much but a jet before the turbo seem to be a bad idea. In certain supercharger application like Zl1 Camaro I think it's possible.

The lower intake tube is definitely a great spot! Can't argue that one. Directly into each cylinder via the intake manifold is also a great spot, but you would ideally put a nozzle before the intake temp sensor as well. The throttle body spacer is by far the worse place to put any injection. There is a zero percent chance of the mixture being spread equally to all cylinders.

We have them in stock, ready to ship.

Lol well then. Just placed an order. You guys are the only ones who have them right now.
Thanks for responding John!

Was about to switch from uni to ds1 to get the flex functionality as uni haven’t provided e85 maps to date for dwna

I’m currently running stage 2 uni ecu and have been happy with it, over run is spot on and exactly what was missing compared to my old iron block

Really happy to see uni working on flex, and will def stick around

With regard to other features, I’d like them to employ the closed wastegate coding to sort the rattle

I also hope the e85 maps fill the noticeable torque hole below 3-4k, turbo response on 98 feels a bit too old school light switch

[WmRS3]

John you doing this for us stage 3 uni guys too?

[S4BB]

@Unitronic - Any update on timing, it's almost time to switch back over to E85.

[GTCRS3]

Yes master, may we have some more?

Unitronic need far better marketing. Read the room fellas, Flex is a game changer on this platform, and one of the main reasons ds1 is current buzz word in the community

If it actually is in development then they should be putting it all over the net and forums to keep focus on themselves instead of customers looking elsewhere

[John@DEADBEEF_DynoSp]

Since we were mentioned, our marketing is simple. We ignore the MBAs that a previous and a present director have, we get something innovative and useful working, sponsor Audizine and a handful of interesting cars and talk about it.

Engineering something better is the hard part for custom features. We have 15 years of experience writing novel ECU code for features like this and remain hungry. It is 10 years since a worthy competitor had a feature war on a platform with us and we are in better shape than last time. We are documenting today the latest feature we have just released that levels us with standalone ECUs. It lets a tuner design their own features in minutes instead of months.

[GTCRS3]

I like your pitch DS1, however there’s no chance I’ll double pay for tuning my RS3 and you were a bit late to market to get my initial purchase.

I’ll flash my Cayman or SQ5 before I double up the RS3.

No offence but I haven’t seen anything that would blow my mind from DS1. Everything sounds very promising and I think the draw is for people who are using currently unsupported turbos. But I am yet to see fast times on that platform.

Unitronic has been pretty much flawless so far with their s1, s2 and hybrid support for me. Car runs 9s and drives like stock, TCU tune that you can feel the difference and amazing data logger software. What more can you ask for?

That's because you haven't done enough research. They also don't publish a lot of times nor do they strive to be the fastest running the engine on the edge. Not saying unitronic does that.

If you think unitronic data logger is amazing then you must still be playing on an Atari and think its cutting edge too. The DS1 and DS2 software is by far the best logging set up out there. You can connect your phone and get logs, change maps, do a multitude of things. If you want to get 100s of data points at sampling frequencies unmatched then just connect your computer. Oh it allows for live map editing in real-time.

[tegxsi]

Many don't understand how powerful DS1 is. I'm sure other tuning companies are intrigued nor can achieve what DS has done on MED17. DAZA, DNWA and even RSQ3 coverage. 4.0T stuff is amazing. Upcoming R8 development...

Custom tuning for your specific hardware needs always better than "one-size-fits-all" tune.

[Phayl]

Still waiting on more DS1 results, the platform seems promising but I have yet to see anything aside from 2 people's Dragy's/runs. In regards to flex, I gave up on Uni ever delivering that, will take it as a bonus at some point.

User marketing > company marketing in this, and the results speak for themselves though.

[ECNMY R]

People are going from standalones back to stock ECU + DS1. 'Nuff said.

Unitronic doesn't have the software chops to compete with this. Maybe DS1 is too late to market to eat too much of their lunch, and many are very committed ($$$) to Unitronic, but for me they're just a good hardware company now.

[John@DEADBEEF_DynoSp]

Our main calibrator is quite happy to set records and win races, you just need to look at his Porsche and McLaren work (lap records, drag records, Pikes Peak wins etc). With DS1 on Audis, we did not aim to make OTS maps to take records except perhaps things related to endurance and reliability like the Cannonball run that our customer took in an S6. We've made OTS maps that are smooth, powerful, safe, have emissions no worse than stock with the best control quality, but we still have over 40% gain from stock on E85 stage 2. We aren't intending to compete with our custom tuners/dealers on drag times or indeed other tuners' drag results as chasing drag times does not make the best OTS maps in our experience. Some custom tuners are doing interesting work, making great power and converting from standalones, enjoying our support and now developing their own features like custom traction control and 5 bar support.

I suppose whilst Unitronic are the incumbent for stock ECU drag times, we're the incumbent for stock ECU flex fuel and custom features. It is natural to compare, but it strikes me that the two companies are very different, there is clearly a place for both and I wish them well in their work.

[OE2]

These conversations always go sideways. This is a Uni flex thread and they have already said they don't have it yet. DS1 is a company that does have flex and tuners. If you're looking to buy something that's out right now there's 1 choice, if you are waiting on Uni there's nothing anyone can say to change your mind. Also for the comments on "I haven't seen any runs from DS1" There are a lot of people posting numbers, just not here. Follow up with a pm to DS to learn more.

[Razzaa]

It all comes down to what you want out of your car. If flex is important there is only one choice right now.

For me, my car spends the entire summer at the track. I care about going as fast as I can on stage 1 ethanol and eventually stage 2. Right now, Unitronic is the proven tune for what I want. Now, if I start seeing custom tuned Stage 1 Ethanol DS1 cars running consistent similar times, I would look closer at switching for the extra features

This is so off topic but can you share your mileage while tracking the car on e85?

I’m expecting shock and awe here!

I'm on IG, FB and AZ and see A LOT of dragy results... I'm yet to see DS1 cars running 9s on stock turbo, hell even hybrids... Like I said, I don't doubt that DS1 may be the latest and greatest tuning platform, I am saying I personally am yet to see the results. You would think the floodgates would open and all these dragy results or dyno sheets would be posted.

[ItalynStylion]

I was told by Unitronic this was going to be something they wanted to release in late April. So considering it's still March, I think it's hilarious that people are still getting their panties in a wad. Chill out.

For me, I'm Unitronic Stage1+. Car is a rocket ship and drives around town like it did right off the show room floor. Their Flex Fuel kit is a killer solution for what I'm looking for considering I just add a few small parts and the money I paid for the tune carries over. And I'm happy to be patient, I'm not going to whine and complain if their solution doesn't come out on my timeline.

[misterleeman]

We all would love Unitronic to have this released in April. However, past history (downpipe, intercooler, etc) has shown us that they don't always make their promise dates. :-(

[nsanity]

Car runs 9s and drives like stock,

9's on Stock Turbo is not a car that drives like stock - when you remember that anything you can remove from the car is out, the exhaust is dropped, skinny brakes and 18's with Radials. And thats *any* tuner. This is a Turbo being maxed out issue - not who can page up the most.

I see what you did there. You took two of my posts and assumed things. I never said my car was stock turbo running 9s and driving like stock.

No one is trying to do that, yet now that we know your statements here lack logic I will just let you babble.

Flex fuel is in development. We had originally hoped to roll this out in Q1 2021, but it looks like Q2 2021 is more realistic at this point. We're packaging it up with some other cool features, add-ons, hardware for CAN-bus integration, iOS/Android applications, more data logging capabilities at faster speeds, and much more. I'm confident you'll really enjoy it.

In the meantime, thousands of our customers use our UniCONNECT+ cable and application via a Windows-based laptop each and every day, with a mobile hotspot, in the event that a WiFi connection is not available, without any issues. Let me know if you have any other questions and I'd be glad to help!

Hi John,

Any news about potential new tuning hardware release ?

Been waiting to get a Stage 1 tune, but if there is a different product than UniCONNECT+ coming I've been wanting to wait.

Thanks

[mobbarley]

DS1 makes my uniconnect look very dated. I’m having an extremely poor and slow flashing experience and the promise of flexfuel is driving me crazy!

[Phayl]

Q2 finna be over real quick, any updates on this? Or ETA?

[DocSean]

Replying in hopes of an update. I'm getting ready to move to the Midwest where there is no 93 but plenty of e85.

Any idea on timing for flex Unitronic? Also, I imagine you can't give away to much sauce, but will the future solution be able to display ethanol content without a dedicated gauge (I.e. P3)? I'd hate to spend $300 tomorrow only to find out I can get a reading right in virtual cockpit with unitronic.

None of it is even needed. Outside of winter blends you are fine filling up with e85 pretty much anywhere. The tunes are good from e60-e85 I believe. Perhaps a true flex fuel adjust on fly tune could squeeze out a tiny amount more power, but nothing to be waiting on.

That may be true for DocSean - where he says E85 is readily available. Where I live, there are not many E85 stations, and I'd like not to be dependent on finding it when I'm out of gas.

[Domino_z]

As I’ve said before, I’d just be happy with e85 support or any kind of continued support for dwna - we’re still on a beta map almost a year later

Except if you can't get e85, now you need a laptop. With Flex - even if you get a batch of winter stuff at e30 - your car is safe.

With unitronic yes #makelaptopsincarsgreatagain

Other platforms like apr and whatever mrc are using, you can map switch

I agree with above, you either want to run e85 or not, nobody gets half way through a tank of 93/98 and decides they want to fill up with e85 to get some kind of e30 blend - if they do they don’t know how ethanol works

Uni’s only option is offering flex, if they had real time map switching they probably wouldn’t need it

There's no e30 winter blends. Maybe e55. I don't run e85 in winter anyway as the starts are terrible for anything below 35 degrees
