Burger Motorsports JB4 high performance tuner for Genesis vehicles

[Beefer]

I had the fuel in my tank for a week driving to and from work all week. Took it out to the speedway for midnight mayhem and was having the issues then. So I had driven the car for a few hours before running it WOT. I was asking if You had any similar issues with the fuel set up you run as to see if it is worth me trying.

When I first started with BOOSTane...I was impatient and went WOT too soon. Car shuddered as you said.

I than chilled and let the ECU do its thing...perfect ever since.

But...I use an exact measured amount...perfect every time.

As for mixing with E85...not sure how much, etc.

Did you do too much? Not enough? What is your final octane measurement at?

I’m running 99 octane.

To run Map 5...you need race fuel...probably close to 104 octane. I’ve never tried it...crazy fast as it is.

^ yeah it is not just a simple plug-n-play. Adaptation is not instantaneous and since you have no control over the ECU itself, you just have to hope that all the stars align and it cooperates!

Hey Beefer when using the octane booster and map 3 are you noticing any pulsing under WOT? I ran the recommended e30 mix and was getting a little unusual feeling on map3 and map5. Much worse on map5 to where the car actually cut fuel supply to the engine to cut power completely

I agree with what others have suggested. In addition to that, it may be a good idea to log some runs and see if there's any timing being pulled, also to see if your boost is holding steady.

Some Stinger JB4 owners have experienced some wastegate fluttering when using higher maps (above map 2), but it seems to be mostly during partial throttle. Assuming your issue is only during WOT, I really think you should record some logs and go from there.

The wastewater oscillation can be mitigated mostly by enabling Bit7 in FUD. Linear pedal mapping.

Went with a slightly less than 30 percent mix as recommended by the burger website. I can not give a 100 percent definite answer as far as end octane due to not know exactly how good the quality of each fuel in the mix was. Found a e85 mix calculator online and it says was roughly 94-95. Plan is to get a few gallons of straight 100 this weekend and see if she like that.

.....To run Map 5...you need race fuel...probably close to 104 octane. I’ve never tried it...crazy fast as it is.

~97+ octane is fine to run on Map 5. At least that's what I was using few times--- mixing 7 gal of E85+~14 gal of 93 octane, according to e85 calculator, I was at 97 octane +/-

Mind you...G80 fuel tank capacity is 20.3 gal.

Honestly...I think you lucked out with really good fuel...and you were probably higher than that in octane.

BMS says...

Map 5: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%.

Map 3 alone takes 93 at a bare min...good luck with that. It runs at it's best close to 99 octane...trust me on that one.

Map 3: 6psi stock tapering to 5psi at high RPM. Suggested for high quality fuel including unleaded race gas, ethanol mixtures up to 30%, or high quality octane booster like Torco or Boostane.

Map 5 needs more than Map 3. Again...if you are lucky you might get away with ~97 at a minimum...but Map 5 will be "happiest" over 100 octane.

Mind you it is not just me throwing these numbers around. A tuner out of VA Beach that has been hardcore with the Stinger has been playing with BOOSTane Pro, E85 mixes, etc, etc. He is the one that started me on these higher octane numbers...and the difference between "getting by" and what the ECU really "loves". Map 3 on 93 octane sucked for me...not a smooth transition. Sometimes the car would bog out, etc. Perhaps I have shit gas around me. E85 is way too far for me to get. So on 99 octane with BOOSTane Pro...my car has a smooth graph transition...never a single issue.

I have never run Map 5...but according to Map 3 and what the tuner told me...well...you get it the rest

There is no way to check how "good" the fuel was, I usually get 93 octane from Shell gas station near me. As you said, it could be higher than 98-99 octane, who knows? .... I'm running on Map 2 since April and the car runs great.

Map 5: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%.

Doesn't this meant E85 mixture up to 30% with 93 octane? I though he meant that, I dunno.

You know what...at this point...this is what it boils down to.

Use the best pump fuel you can find. If you want to use Map 3...you know you will need to be better than 93. Pick your poison on how you want to do that. Play around. If your car hesitates...increase your octane...find your sweet spot

I found mine...and am sticking with it. Since I drive so little...the cost hit for running the BOOSTane Pro at 99 octane is not an issue for me. If I logged more miles...no way I would do that...too expensive.

Next...in the winter months...I will stop using the booster...and simply run Map 2 on 93 octane (Shell).

Na zdrowie !

 

[dareckibmw]

Haha, that's exactly what I do and I think 93+Map2 is better than Map 3, iirc, we talked about it over the phone, lol

For kicks...buy a bottle of BOOSTane Pro...$30 from Amazon...

Robot Check

Next time your tank is empty...use the chart and fill your tank getting to 99 octane (doesn't have to be full tank...but get to 99). Then run Map 3 for half an hour...let things mix and the ECU to learn.

Then reply back and tell me what you think of Map 3

My tank is 16 gal...close enough. My ratio is 1/2 ounce of booster (Pro) to 1 gallon. So my full tank takes 8 ounces. The Pro bottle is 32 ounces...so 4 full tanks for me.

Note it says 0.43 ounces...I just rounded up to 0.5...so much easier to deal with.

So let the car run all the way down to 10 miles until empty. Put 10 gallons of 100 octane race gas in. Obviously wasn’t paying attention cause I was not planning to spend 80$ on that lol.

Drove around for about an hour on map 3 letting it all adjust. Ran a number of pulls with logs and still getting surging at times. Looking at the logs the it seemed to be running a bit lean. I unplugged the fuel wires and immediately the car was running Incredibly strong with 0 surging issues. Also ran into a 2020 Supra and dude was cool enough to roll race from 50. Sat door to door with it from 50-120mph before we backed off due to traffic. The Supra maybe picked up 5-7 feet through the pull.

All in all I think more bolt ons are needed for fuel wires and living in the desert of Nevada. Or wait for the temps to drop down into the 60s and give it another try when that happens.

Was the Supra stock?

Play with the fuel bias settings. When you say lean, what did the AFR show on the log?

More than likely the Supra was stock.

Give me a few to go back and find the logs. I have close to 100 from the other night

 

[Vortex951]

I was getting spikes( not consistently, and not every time) in the 13.5-15 range. After I unplugged the fuel wires and gave that a try the afr would be anywhere from 11.5-11.7 through an entire pull starting from 30mph and running up to around 100 even more at times. I’m not super familiar with playing around with the fuel bias settings either. Is that something that is in map6 or for all maps?

 

[jwalkingjon]

Deff grabbing this if I pickup either a stinger or g70, Haven't decided which yet!

I did an experiment similar pull the fuel wires off on map 3 7th gear pull 70ish to 102 or so they look almost identical with or without the fuel wire


Wires off



Wires on

That is odd...Did you email JB4 support?
