Map 5 JB4 runs amazing on the Stinger.

About 96-97 if using pure e85 and 93(e10).Ethanol Calculator - Brew City Boost

Someone did a thorough test on octane and map3+ and showed 96 octane minimum was needed to avoid the ECU from pulling ignition timing.

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

No, use the ethanol calculator. E30 is about 96-97 octane and that’s what’s needed for map3+.

No 6-7g would be over e40 and too much to run on a daily or without a fuel-it kit.

Okay perfect. According to my calculations I'm about E32-E34.

I'd think those mods are capable of a little better? I'm same but with muffler delete too. I know a few guys with similar mods have run high 11's or flat 12's. As you said shit air+wind, so maybe without that you're something like an 11.9. Are you RWD or AWD? I'm AWD.

yeah it should be good for more. I have since done the brake snip and Im hoping for better conditions next time. That was cool because I wanted to kind of gauge my "real world everyday" results, now I will go for maximum effort. I am going back out this week so I will report back

There are only about a half dozen Stingers in the 11s without the brake snip. Jb4, intake and muffler delete isnt going to do it.

It seems the octane requirements for map3 / map5 are about the same? Anything different, other than an extra psi?

Map5 does not taper in higher RPM. Horsepower/Torque does not fall off as much after it peeks in lower RPM. "Pulls right through". According to the JB4 forum it calls for E85 mixtures of up to 30%. Not sure if there is a difference between that and E30. Hopefully someone can chime in on it.

So using BoostTine it would be about 5 oz. per 16Gal 93 oct fill up? And each 1 QT can has about 32 Oz?

 

[zbc1969]

No gas stations sell 93 where I live because of the altitude I live at. The highest I can get is 91 at normal gas stations. If I want to run map 2 can I run it safely on 91 octane since I’m at ~4,000 ft elevation? Or do I need to use some sort of octane booster to get up to 93?

I believe that's correct, but see Terry's info and my explanation below...

You must be thinking about the difference between map5 & 7.

This is what Terry posted about the different maps 3, 5 & 7:
"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: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%.
Map 7: Up to 7psi over stock but without top end taper. For unleaded race fuel use and bolt on modifications..."

Yes e30 is simply 30% of pure e85 added to 93 octane.

The Boostane mix depends on the version you are using and what target octane you are trying to achieve. Someone tested map3 and said you need at least 96 octane to avoid the ECU from pulling ignition timing. Based on that using Professional you'd need at least 2.72oz, but for Premium you need at least 3.84oz per 16g of 93. Here's a mixing guide for more details.


A quart is 32oz so you can get about 11 tankfuls(~$3/tank) out of a qt bottle of Professional, and about 8 from a qt of Premium.

Simply answer is yes, it will run safely since the ECU will automatically pull ignition timing if needed to avoid knock/detonation.

Also per Terry's post about maps1 & 2:
"Map 1: 4psi over stock peak tapering to 2.5psi at high RPM. Default performance map suitable for all 91+ octane fuels.
Map 2: 5psi over stock tapering to 4psi at high RPM. Suggested for 93+ octane fuel."

Some people have run map2 on 91, but that depends on the quality of the fuel and best to run logs to see how its performing. If timing doesnt stay stable and/or keeps increasing throughout the rpm range then an octane booster may be needed for maximum performance.

Hope that helps and happy tuning.

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?

 

[Regs120]

Thanks for the info. Is there a limit to stay within for octane? I heard 10:1 compression maxes out at 100 octane which should give us plenty of breathing room at 96.

 

[KiaStingerNewb]

There are only about a half dozen Stingers in the 11s without the brake snip. Jb4, intake and muffler delete isnt going to do it.

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.

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?

Once you go to v13 firmware that +8 will be 22 psi. I think low 12s is about right with a lighter GT descent temps and low elevation. Lots of 12.1, 12.2 cars not many 11.x without snip. I think i counted 8.
Primary and secondary dps don't do much so you have the big hitter mods. Wmi or fmic does help.

Yea FMIC is next on my list for hopefully another .1-.2 with less heat soak. I decided not to do primary and secondary for the reasons you said. A lot of $ with no gain. What do you mean V13 firmware??

Update your jb4 firmare and the boost reads higher now. If you hit 20 before its now 22. Better aligns with obd and hardware boost gauges.

How do you update firmware via BT? Is it in settings?

 

[Tonkabob]

4th option under jb4 settings is firmware. It takes you to jb4 website to down load. Directions are good.

So is it actually hitting 22PSI or just making it seem like it is ??

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.
