Map 5 JB4 runs amazing on the Stinger.

[Tonkabob]

Isn't E30 only 94 octane? Does that mean I should be running more like 6-7 gallons E85??

Depends what you start with. E10 91 vs E0 93 to mix with E85 to make E30 will have very different octanes.

It actually is. Before the JB4 read about 2 PSI low. So no change in the tune just the PSI is more accurate some would say.

I had switched my boost fail safe back to 20 before I updated the filmware since for some reason it went higher.

That being said it would hit the max boost on map 5 correct?

 

[KiaStingerNewb]

Damn it i got another bad mix. Too much E85 maybe. It's crazy how some tanks of gas vs others there is a huge power difference. Maybe reset my adaptives?

Ps having a hell of a time updating firmware from phone lol.

I'd bump up the fail safe to 23 or 24 on v13.

If you have a weak signal holding phone close under hood can help, as can turning off wifi on the phone.

I mean when I click file it doesn't download. Is this why?

 

[Regs120]

The firmware update makes sure the gauge shows actual PSI for accuracy. It's not adding performance.

Yes. Turning the WiFi off on your phone is key. It should work after you do this.

I typically download the file to my phone using wifi in the house. Then I go out to the garage and update the firmware. Seems easier that way.

I got it updated. The meters look the same, don't have that cool orange bubbly look a lot of people have. Mine is the green bars still lol. BTW maybe it's in my head, but since the firmware update (mine was way outdated) the car seems to perform more consistently in the hour or so I've driven it. People said it's only to update for more accurate PSI reading, but if you read the thread with the actual file, it's more than that. Map 5 is more lean, and other tweaks had happened since my version.

You change the gauges in the settings tab

In mine I just have two theme options, and colors for bars. It doesn't have that gaming MMO style bubble letters most people on Youtube have with JB4 which looks sweet IMO.

Finally got it. BTW via experimentation I figured out something, that may not seem logical to you though. Sometimes my ratio of E85 I think is closer to E45-50 based on misjudging the gallons and estimating. When that happens, I actually LOSE power I feel like. Not sure why you'd lose power with higher octane, but I added 3 gallons of 91 to see what happens, and sure enough right away the torque gain was obvious. My first right hand turn my rear wheels broke loose (AWD). It's crazy how little things affect the performance so much.

You really gotta get the ratio down for optimal performance I think. When I was slightly below E30 I didn't really have power issues. It seems to be when I'm way over E30. Also since updating firmware the E85 reading is much higher. It went up like 10+ points just from updating.

Terry has posted that E40 or E50+ can result in not enough fuel at higher rpms. Also called "fuel pressure crash" or similar. To be avoided at all costs.

Okay. Ill be more cautious. Wish here was an easier way to know exact E85

There is - fuel-it makes a sensor you can install that will show you the exact ratio entering your engine, and the jb4 can even hook up to it to read the sensor. It doesn't tune-on-the-fly, but I think it will provide some "ethanol too low" protection.

Fuel it sensor and JB4 integration works well.

thanks this helps a ton! Noob Question though, do I monitor it through avgIGN or one of the IGN 1-6 gauges? Also what do the values mean and what am I watching out for?

YW. Best to log and view IGN 1-6 as you could have ignition drops in individual cylinders so just watching one is useless.

The numbers are simply degrees of timing advance. They will vary a lot depending on on throttle input, boost, etc so you mainly just to make sure your timing stays stable and/or increases as you go through the rpm range. Look out for multiple drops(staircase effect) as that’s a sign you aren’t running enough octane for the boost levels.

So more like low-mid 12's? Map 5 is like 8 PSI over stock I believe at 19. Also I'm basing that estimate on the times he got with those conditions.

Yeah Terry and others ran low-mid 12s with just intakes and limited traction, but 11s are hard to do without AWD traction & the brake switch.

Map5 is +7 psi and around 20-21psi on latest firmware.

I ran Map 2 for weeks on pure 91 with no issues from the short logs I posted. That being said by week 2 I wanted to experiment with higher maps and I've been E30-E35 since (sometimes I'm a few octane points higher due to fudging ratios etc). Hmm... I wonder if I could ever get away with Map 7. Same boost, but I wanna see what it's like without losing the top end. I have bolt ons, or does it mean beyond intake/exhaust work? Race gas as in like a full tank of 100+ octane? Or can my 95-97 octane blend get away with it?

Map7 is really pushing our turbos & fuel system to the limits and e30 isn’t recommended for a few reasons, especially with mixing only 91 octane. Our fuel pressure drops with ethanol and high boost levels which is why race gas is recommended instead. Im not 100% clear on what bolt-ons he’s referencing but likely FBO would be best for most airflow in & our to keep EGTs down. I’d follow Terry’s suggestions and only go up to map5 with e30 mixes.

Damn it i got another bad mix. Too much E85 maybe. It's crazy how some tanks of gas vs others there is a huge power difference. Maybe reset my adaptives?

You need to be careful and accurate with your e85 mixes. As people have said too much ethanol with high boost can drop fuel pressure which is dangerous and could potentially hurt your engine. If you’re going to use it often or keep experimenting then get the fuel-it sensor kit so you really know how much you’re running. Also make sure to mix it up the best you can before going WOT so you know it’s blended well and not just getting the e85 that you put in first.

And yes there has been some significant changes over the last two firmware updates and supposed to be smoother and better power delivery overall.

With the Fuel-IT flex fuel sensor kit the JB4 will tune on the fly for E85 mixtures, within E0-E50. To get beyond E50 we'll need to make some flash changes once at home flashing opens up.
