Custom Map / Custom Tune on JB4 for Supra :: 1FastSupra

[@magnetman3t725]

I’m thinking about JB4 and the 500hp range seems to be a good amount

[@papa7189]

Jesse tunes are the truth. IJust got a custom e30 tune on my 2022 supra from Jesse the car is moving now.

[@spiguyversgarage9452]

For real, Jesse is the guy for the Supra and JB4.

[@billcoaby2498]

How does it compare to the regular map 2 and 3 on the jb4?

[@gogz1981]

I had jesse JB4 custom tune my ‘21 M340i RWD (MST intake, AA DP, XHP stage 3, E35) and like you I couldn’t be happier. Car runs quite a bit smoother and the jerkiness is pretty much gone.

[@spiguyversgarage9452]

It's night and day from stock!

[@TerrannotOP]

Are you able to keep up with stock gtr and c8?

[@marke6196]

Just bought the daul maps for 91 and e85. Can't wait to see how it pulls 🤟🏻

[@spiguyversgarage9452]

Sweet! Have fun with it.

[@TronB58]

Plz keep up the JB4 content. You're my favorite supra youtuber

[@spiguyversgarage9452]

Oh man, I appreciate that!

[@clplusp8762]

Here I am waiting patiently for more options to become available for my 22 mkv. I’m near Titan so I may give it to them for upgrades because I’ve long gotten used to the OEM power level.

[@spiguyversgarage9452]

Right on.

[@khmerairmanusaf291]

Love the back grounds.

[@spiguyversgarage9452]

Thanks man, one of the best back roads in the general area!

[@khmerairmanusaf291]

Yeah. It’s really peaceful place to get away from the city life

[@jakeatkinson901]

Good video. I approve this message..lol....Jesse tune+ jb4+ meth get some pretty insane results consideringits just a piggyback. I have smoke a lot of really fast cars out there that I didn't think would be possible at all. Definitely gotta be somewhere around 500 hp.

[@spiguyversgarage9452]

Right on, glad others are seeing great results with this as well!

[@marke6196]

What year do you have and mods?

[@utahsrealtyspot6917]

Did you dyni it to claim 500whp? I also have JB4 tune by Jesse. Curious where you got those numbers.

[@Fucyocouch]

On the website he linked in description the guy has a dyno picture with the 500+ not sure if it’s spiveys but that is a lot with jb n meth

[@spiguyversgarage9452]

It was part of a dyno event at a new shop that was running people through as part of a competition. No slips were handed out, I'm sure there is a photo of it somewhere. It was not on a Mustang or DynoJet, I'll get all the info and post it up. Maybe we just need another video dedicated to a dyno day!

[@papasfritas0]

So what is your best 1/4 time on the draggy?

[@spiguyversgarage9452]

I haven’t done many 1/4 passes, and even less on the dragy. Since putting better tires on I haven’t done any. Best drag strip pass on stock tires was an 11.2

[@essakaram7387]

So I know there is an expensive option to unlock the exu or clone it and the jb4 is a piggyback option, but is this how it will always be with the 2020 june+ ecu’s or is there an unlock solution in the works? I just got a 21 supra and I am afraid that there will not be a cheap unlock service.

[@spiguyversgarage9452]

There are a lot of companies trying to figure out a way to unlock these ECUs for tuning. It’s not just a Supra problem, but impacts many other brands like BMW, Mercedes, Lambo…. It will happen, it’s just taking longer than most of us hoped it would.

[@highboost1459]

Do you have dyno numbers?

[@1FastMKVSupra]

So what happens when you go from a summer 100 degree tune to winter when you can see much less humidity and temps, say like 50…..

[@spiguyversgarage9452]

In my experience, I've worked with Jesse and made hot weather and boost weather config files that I can load for the different temps.

[@invasion1824]

Can I just use the jb4 and a downpipe? How many horses will I get from just these 2?

[@static-co]

Can you feel a big difference with the jb4 from stock ? I’m considering buying it, rather then paying 4K plus to get my ecu flashed and tuned.

[@spiguyversgarage9452]

Yes, there is a noticeable difference. I did some comparisons when I first got the JB4 and I did a video that shows the differences. Looking at my dragy slips, when doing 40-100, I got 7 seconds stock, and with nothing other than the JB4 cut about a second off of that.

[@domlouis2179]

Quick add. I have just used Map 1 only since no supporting mods and DD. I will say sometimes the graph is showing me some boost spikes that get me nervous but bone stock it's a great "boost" (see whatididthere) with extremely quick install and convenience.

[@13randon98]

Just out of curiosity, would JB4 throw your warranty out the window?

[@spiguyversgarage9452]

It could...

[@kojpim271]

How much was your tune?

[@spiguyversgarage9452]

It's not an ECU tune, so it's quite a bit less than those. Check out the different plans on 1FastSupra.

[@TerrannotOP]

How fast on 1/4 mile

[@spiguyversgarage9452]

Best is upper 10's. Not super fast, but not slow. I'd have to grab my dragy data to get you the numbers.

[@salgado1601]

Do you plan on doing a dyno? I would like to see the power you are getting out of the jb4

[@spiguyversgarage9452]

I've done a couple of dyno sessions so far. Had some issues on the first one. But the second one went much better.

[@salgado1601]

@@spiguyversgarage9452 thanks for the info…just got my supra and i had no idea the ecu were locked on the newer models…so im gonna invest in the jb4

[@2jznat]

Mark we need to talk.

[@SpiguyverBackpacking1]

Okay, about what?

[@israSam]

please share your 60-130 time

[@SpiguyverBackpacking1]

Best is 8.34, consistently in the 8.5’s.

[@israSam]

@@SpiguyverBackpacking1 thats fast, enjoy it

[@Giuliaveloce23]

Are you gonna show anything or are you just gonna sit here and talk all day they like it it’s a fucking infommercial

[@uiali8998]

Still not as good as a full dme unlock imo.
