Let me first say this is not a JB4 vs Lap3 nor a place for people and companies to bash one other or other members.

This is simply my own first hand comparison between the two.

Had my JB4 BT w/ plug & play fuel wires on my new 2020 Stinger GT RWD, at just under 3,000 miles on the car, Dec/2020, now has over 22,000 miles.
Been on Map 2 93 oct gas.
HKS plugs gapped to 0.022.
Mods are JA snorkels, K&N intake, AP FMIC, MBRP exhaust, 20mm spacers, lowered on H&R -2 springs, stock primary and secondary DP, stock TCU, stock wheels and tires PS4, probably 10K miles on them tires. (2nd set)
Never had any issues running this setup as my daily driver, no limp mode.

Got a dragy just for this comparison.
For this comparison. I tried to keep everything the same.
Same 2 strips of road for 1/4 mile runs, same time of night. Same amount of gas in the tank (1/2 tank), same weight in the car. (Rocking 2 car seats in the back )
Also got an ethanol tester to make sure I got correct amount of Ethanol.
For this comparison, I did:
JB4 map 2 93 oct
JB4 map 4 E30
Lap3 1.5 93 oct
Lap3 1.5. E30
Also I let the car shift on its own to keep everything the same.
Kept traction & stability control on, due to I’m already spinning.
I probably did 6-8 1/4 miles pulls for each group of test.
When the Lap3 ECU was in, the JB4 was set to Map 0 and the fuel wires are disconnected.
I’ve keep 4 logs of each group and 4 0-60 times and 4 1/4 mile times.
0-60:
JB4 Map2: 4.74, 4.77, 4.84, 4.89
JB4 Map4: 4.59, 4.68, 4.77, 4.86
Lap3 93: 4.95, 4.98, 5.07, 5.10
Lap3 E30: 4.90, 5,00, 5.08, 5.09
1/4 mile:
JB4 Map2: 12.69, 12.74, 12.76. 12.83
JB4 Map4: 12.53, 12.57, 12.61, 12.61
Lap3 93: 12.73, 12.75, 12.82, 12.82
Lap3 E30: 12.54, 12.59, 12.66, 12.69

I think my tires were the factor here. By the time was to test the Lap3, my tires were getting bald
By the time I was done testing Lap3, the tires were bald.
Last year May, my 1st time at a drag strip, on a 1/8 mile track, I consistently ran 8.1-8.15, on JB4 Map2 93 oct, at that time I did not have the AP FMIC.
My best 1/8 on the dragy was 8.29 overall for these run.
The streets are no were sticky like the track.

About 3 weeks later, I dyno the Stinger at our Tampa Bay Stinger Dyno day.
Full tank of E30
I did 4 pull, 1 & 2 on JB4 Map4 and 3 & 4 on Lap3
They were only able to print 3 pulls per sheet, so Sheet 1 was pulls 1,2,3 and Sheet 2 are pulls 2,3,4.
See you can see the Lap3 made so much more power.

Dyno numbers
JB4
Pull 1 451/474
Pull 2 446/489
Lap3
Pull 3 478/522
Pull 4 482/524

My butt dyno, Lap3 is smoother power band from start to finish and feels no delay, it just wants to go. No maps to switch between. It adapts to the fuel type and the car.

JB4 install was a breeze. Hardest part is getting the OBD wire through the firewall. Or hiding all the wires. Customer support is top notch. I had to replace the master chip, no problem getting to the issue, they always help with your logs.

Lap3 install was pretty simple too. 2 of 3 screws holding the ECU bracket are harder to get too. Had to remove the plastic part getting in the way to get to one of the screws due to I just have very basic tools.

When I 1st receive the ECU. It wouldn’t pair to the car, tried and tried, swap back the oem ECU would work, then tried again with lap3 ECU, still would not pair, messaged David from lap3.
Had me send back the ECU to get reflash, about 1 week later got the ECU back to me.
This time it paired in the first try.

Question, should you get JB4 or Lap3 ECU. Or upgrade from JB4 to Lap3 ECU
For me it’s a yes and no.

I won my Lap3 1.5 ECU in a raffle.
Join this FB group, (Shameless plug) Kia Stinger Waffles and Giveways.

If I didn’t have won it, I would have not bought it out right. It’s $2,000 but had a discount code at the time for 10% off. $1,800.
I’m more then happy with JB4 and would have stuck with it if I didn’t win the ECU.
I daily drive my Stinger, 90% is going from home to work and picking up kids from school.
I don’t track, drift, auto x the Stinger. I’m not out for the highest HP not going for the fastest out there. No plans for Primary DP, maybe secondary DP. No plans for WMI.

Question you would have to ask yourself. Is the cost/benefit. What type of driver and what your using your Stinger for.
If your the avg Joe just looking affordable, best bang for you buck, can’t go wrong with JB4.
If you have cash to burn then go Lap3

I have no clue how to read logs.

But I’m more then happy to email my logs to anyone. Just PM me.

Hope this helps you fellow Stinger

Nice. Great comparisons with tons of Data.

The lap 3 is making more power but the Jb4 map4 is going faster 0-60 by a 10ths of a second but the Lap3 almost catches it at 1/4 mile but its damn close.

Im running a Jb4 on map4 ocasionally and realy dont see a reason for now to push more out of it.
I really like that i can street it in any map i want with just a app on my phone.

For instance im dropping my car off for Tint on friday and its going straight into Valet. Also if that Tint tech for some reason does drive it and try to stomp the throttle Voila ... brand new log thats dated . Smoking gun evidence.

Good ass comparison and well detailed write up. Thanks for sharing bro
 
______________________________
Yes the times are way off what they can be and what they should be at.
But my tires had about 10k miles. Not much rubber left. Street roads suck. And letting the car shift it self, due to wanting to keep everything the same as much as possible. Limit and variables.
 
This is why I’m considering lozic because the price of one ecu with lap 3 I think is damn near the same for a lozic ecu & tcu. I’ve been on map 2 with 93 octane for a year now. I’m ready to go next level. Problem is there is no e85 nearby so I’m wondering if I should even bother getting deeper. As far as I’ve read going ecu and tcu tune with all the bells and whistles makes the stinger a totally different animal than my current jb4 set up.
 
From interior to exterior to high performance - everything you need for your Stinger awaits you...

Tork TCU has been really good paring with jb4
$99 at present.

What’s the difference in price with the lozic ecu and lap 3 ecu. Lap 3 ecu stage 1.5 running about $2400 with all the bells and whistles. How’s the reliability with the lozic ecu tune and price ? How do you get in contact with lozic ? Email ? Ig ?
 
Made a thread with the data from each also. :)

 
Nice write up op.

Pretty confused at your 0-60s though. Those are stock numbers.
 
Yea

yea Just shitty traction, tires has 10K miles already. Street road. Car shifting on its own, due to wanna try to keep variables at a minimum
Spin city

Am I missing something? I thought you had to have your phone in the car and jb4 loaded / connected to log? How do you log remotely? Or are you leaving your phone in the car?
 
Correct, no log if you don't have the phone in the car with the app connected. At least as far as I know...
 
I think this review shows that if you are unless looking for maximum power, probably best to go ECU with stage 2/2.5 and supporting mods, but anything less than that a JB4 would be way cheaper and provide almost the same performance as the milder ECUs and the convenience of data logging and switching maps and CPI/Meth control is a plus.
 
I'm curious were you using launch control, or e-brake holds, or just flooring it from a stop. I love running Map3 E30 in my stinger. Very nice comparison thanks!

Just flooring from a stop

Update. I did do a 60-130 E30 full weight. 9.34
