So I made the jump from RaceChip S to a Jb4 and currently enjoying the drive in Map 1 on 93 octane w/Fuel Enabled. The differences in power delivery are quite obvious. With the RaceChip S it felt like it was slipping gears every time it shifted -or like it would constantly jolt between gears with overboost. The JB4 offers a welcoming smooth power delivery through the gears and it is very punchy in sports mode. As for power, I believe the two offer pretty good power but obviously the JB4 map1 with fuel wires and OBDII offers a lot more up top and even more so on the bottom. I am almost fighting a bit of torque steer now off the line, but not enough to lose control over it. Bottom line is that the JB4 feels more tailored for the Stinger making it a overall more pleasurable driving experience.

Unfortunately I am stilling running stock plugs but for 200 miles of test driving I don't feel a hitch or stutter. I will likely in the next month get them updated to Denso's .22, but for now I will enjoy Map 1.

Map 2 says it only adds marginally more peek power, but if it tappers at 4psi instead of 2psi extra, then I imagine it pulls a lot harder in higher RPM making a lot more difference for power over the entire curve and not just the peek. I am hoping to try that as soon as I get my spark plugs replaced.

I was thinking about Tork tune or Pressertech, but it came down to price and availability. It does not make sense to mail off my ECU right now for a possible 3-4 days of down time. And if the dealer ever reflashed it, though improbable, it would be a large head ache. We need our own flashing hardware for it to be practical for me.

On a side note, I just had a Acura TL (probably 2017-2018) try to dance with me on a roll going on the highway. I am not sure if he was just trying to piss me off, but it was fun watch him give up after I kept pulling hard after 100mph.

Glad to hear you made the switch! If you need any tuning help we're here for you. But do the plugs ASAP. At least regap the stock ones!
 
Thank you! Just made an appointment request to get them done.

Do you have any other bolt ons? Intake?
 
Nice. Smart move! Plenty here have the jb4 so any questions feel free to ask... once you get those plugs in slap on an intake and take map 2 and 3 (depending on octame) for a whirl
 
From interior to exterior to high performance - everything you need for your Stinger awaits you...

Thanks! I thought Map 3 is only for corn juice or meth? I would love to reach that over 400+ whp mark soon.

map 2 is for 93 octane and map 3 is for 93 + some E85/ Octane booster, but there have been quite a few that run it without issues on just good 93 gas.
 
Running Map 2 or 3 daily using 92 pump with a bit of Boostane to get to 96+ octane. Zero problems. Note: this is habit forming. When I cut back to stock briefly the other day I resolved to avoid doing so in future.
 
@Regs120 Cool! Not to Hijack your thread but, I just got my Jb4 today from Khartunerz:)

Map3 runs best on 96+ octane and a lot of people use e30 or Boostane to get there.

And map2 with intakes will easily get you over 400whp. Map2 with only 91octane and intakes gets you around the 415-420whp/515wtq range.:thumbup:

Ok stupid question - how do I know if my fuel wires are attached correctly and the JB4 knows?
From what I’ve read the easiest test is by running logs and looking at the “fuel en” or “trims & trims2” results. If fuel enrichment is changing throughout the rpm range and the trims go down, it is working correctly.

That's what I am thinking - plugs, map 2, and a couple of high-flow filters for now.
Just remember you will miss out on 15-25whp using the stock airbox even with higher flow panel filters. If cost is a factor just build your own intakes for about $100 like I and many others did.:thumbup:
 
Ugh! In the near future for sure. I am getting my spark plugs replaced with Denso's at .022 this Saturday. Then I am turning on Map 2.

Where do I find the JB4 software? I cheaped out and got the USB/PC wire.
