jb4

I have a 22 3.0 premium I have a armtrix catless dp, hks exhaust and hks carbon intake I plan on doing 93 but is it worth getting a custom jb4 map for just that. Not really tracking it, just street and driving for fun. I’m being told by other owners that’s it’s not worth that much money (500$)...

For my JB4 guys, I went out and did some testing of all the maps including map 0 (JB4 disabled) on an E36 mix. Mods: Magnaflow XMod Exhaust Eventuri Intake INJEN Chargepipe Mishimoto Heat Exchanger 4.5in Catless Downpipe JB4 My personal best I’ve gotten on map 6 is a 9.36 with a passenger...

So I posted a thread not too long ago of some logs I did while running map 5 and it wasn’t pretty, I was informed to try out map 4, here are those logs. I’m concerned with the afr’s @ColonelAdama @Jesse DaBears

I’m running e30 with a catless downpipe and mst v2 cold air intake on map 5. I started out on map 2 with 93 pump gas and everything felt smooth. Everything still feels smooth it’s just I feel like in the logs the timing is doing some weird stuff it’s kinda all over the place. I put some WOT...

SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1) Been a busy 5 months learning nearly everything there is to know about JB4 on the B58 platform. Funny how trying to get my catless MT running right turned into countless log reviews and custom tuning on the JB4tech.com forum. As Jesse said it...

Hey guys! First post here. I've had my 2021 Supra for about 3 months now and I've just installed a JB4 with EWG. The only modification it has right now is an Armaspeed CAI. These are my Map 1 logs. I don't think I'll be going higher than Map 1 or 2 but I also don't really know what the other...

Sold my lemon supra, no longer need it. Will ship to the lower 48. Used for about 4 months. Comes with OBDII power cable and DMD/"Wireless Smartphone Connection kit".

I have a '23 A91 MT and the JB4 is throwing this code. The description says it's high idle after cold start. I'm running map 2 at the moment and sometimes I experience what I can only describe as rpm hang? In-gear there's very little engine braking. I wonder if it's related.

Hey all, I’m entering custom settings for a jb4 map 6 tune on the iOS, however, every time I save them, it adds .1 to every Boost option except for 1500 rpm. example 1500 -3.0 2000 - 3.6 (should be 3.5 as that’s what I entered on that field in the app) 3000-4.1 (should be 4.0) 3500-4.1 (should...

I actually bought this from another forum member but I never installed it in my car. They used it for ~700 miles. I'm just not looking to tune right now. Ready for JB4 Mobile app management. Unlinked from account and ready for a new host. $375 shipped but would prefer pickup in Orange County...

Hey Guys, Has anyone run the BMS JB4 PI controller? Does this require an unlocked ECU/DME? https://burgertuning.com/products/jb4-port-injection-control-module?variant=43278733508782 Wonder Twins activate? @zrk @Jesse DaBears Thanks!

To be upfront I will not be naming the shop that I worked with as to not cause any problems if there ends up not being any. So a little backstory, I had a shop local to me that deals in race speced cars and tuning that did exhaust work, coil overs and tuning for my 2020 supra. I asked the...

Hey Folks, I've recently started tinkering and researching all things JB4. Kevin (YouTube: kern417) published a video about piecing together an ethanol analyzer which is less expensive than buying a commercial flex fuel kit which can run between $295 (Vader) - $500 (BMS/Fuel-It). Kevin...

Should I be concerned or am I over reacting? Currently running the car on JB4 map 5 with E30 blend. Not sure if it is the switch in fuel that is causing it but this is my first time hearing this sort of noise. Now I will say that I switched over to E30 and Map 5 about 4 days ago from the time of...

Hi, looking to buy JB4 w/ EWG, Bluetooth. Please write me if you want to sale yours. Need shipping to 19809

I've seen repeatedly on these forums that everyone has their Map 6 settings dialed in by Jesse for ~$500 or so. I found this rather unusual just coming from a MK7 GTI that I've been running Map 6 for 7+ years (never had an issue, even at 26+ psi stock turbo e30). I was able to dial it in myself...

Hey everyone, I’m running a catless downpipe and E30 mix on a jb4. after the install it felt like the power delivery isn’t very smooth and the gear changes are much slower. I’ve tested Map 3 +6PSI and Map 5 22psi absolute target. Map 5 feels fastest but I think it can be optimized. any...
