If u log and dial in map 6 u can tune it however u want with jb4. But i agree the off the shelf jb4 tunes are not goos. That said, i dialed in mine to feel pretty much like a flash tune in terms of smoothness but im not pushing the power limits

I don’t have any tuning experience with RaceChip, or JB4. I’ve been tuning turbo charged cars, since the mid 1990s and to my highly untrained eye, it “looks” to me like the JB4 chart being all over the place, is it trying to control the waste gate. That’s really the only thing that makes sense to get this kind of spiking. The RaceChip is clearly better at controlling either the map sensor or the boost solenoids.

[@WhatsyourForte]

The JB4 is trying to control the waste gate where the Racechip is trying to control the cam sensor. You can fix this issue with the JB4 by running a custom map

[@g.dubyou6263]

@@WhatsyourForte ok, good, so, I was pretty close. 🙌

[@payamh9118]

@@WhatsyourForte No, the Racechip is getting RPM by the cam signal nothing else. You can ask them yourself. Would be good to see the DRF files and compare the actual STD VS SAE and smoothness of the charts.

is the part really good does it really add to the extra power can you feel the power? 100-200? I fill up with 102 octane and drive series with my M4 XDrive 100-200 in 8.2 seconds

[@TheMalfunctionGaming]

By chance do you know if you still need to run the car in efficiency mode or has this been fixed? I want to run the JB4 on map 2 but rather get a race chip if I can’t run sport+ and get full gains on the G80 M3 comp xDrive

I am always hyperventilating on the dyno.. I know it will be ok.. but still just have seen videos of straps failing, other nightmares. Yet back I go for dyno tuning in probably a month.. lol

[@Kc2Heatz]

Does this void warranty? I don’t own a bmw yet but I’m curious cause I’d most definitely get the jb4

[@WhatsyourForte]

There is a long debate about this. Some will say yes, some no. Talk to your service team and then make the best decision for yourself. Dinan also has a piggyback now

[@sandman7167]

I thought with Atleast the air intake and base specs of the g80 comp. You would be running more than 500hp at base. Loving the car and can’t wait to get mine.

[@WhatsyourForte]

That intake is an early production model. That could effect numbers. I dyno'd more than this amount with my MST intake base.

[@js002003]

visiting this 2 years later looking for a piggyback for my g87. great content and analysis!... one thing to keep in mind on the rwd cars is that the jb4 power spike at 3k may cause loss of traction making it slower than the more progressive power delivery of the race chip. also, I believe jb4 allows you to limit boost in lower gears to avoid this.

[@WhatsyourForte]

Thanks… yeah if you like to play around more JB4 offers a lot more customization. You can also work with them on custom maps

[@noahs2ndchannel]

so if youre racing and need maximum power, you'd need to be in efficient? what is the point of sport plus mode then lol

[@WhatsyourForte]

With a base car sport plus is great. With the way the piggybacks work by trying to fool the car you run into this issue. When a true flash tune you would not have this issue either.

[@therabbitsfoot6609]

[@WhatsyourForte]

Yeah it is a good looking car

[@NigelDRealest]

when you say efficient, is that the same as Eco Pro? Also, does this throttle staying open thing apply with Racechip too or just JB4?

[@WhatsyourForte]

On M cars efficient is the lowest setting on non M cars eco-pro… they don’t put eco-pro mode on M cars. So efficient in a M car is equal to the level above eco-pro

The only serious drawback is that you have to connect it to the OBD2 port for it to work. All other analogical piggybacks on the market had it engineered it with no obd2 requirement.

[@WhatsyourForte]

Yeah that’s the one thing I don’t like about JB4. But doing that allows you to data log and has other benefits.

[@totalkaos6969]

Ok,, in that case ,, run your 0-60 and 1/4 mile on efficiency and sport plus to compare to what you're saying which puts out more hp on DRAGGY. Run times etc.

Thank you for the great content 🔥. Could I ask if installing Race Chip would void your warranty? Would BMW be able to tell you installed it?

[@WhatsyourForte]

Thanks, Some say they can tell and some say they can't. I can only say that I had warranty work done after taking off the racechip. I think it depends on what you need done. Like if your trunk stopped working they are not going to look to see if your car is tuned. If your engine blows up, they will look.

Nope. You need a true tune to do that

[@FreshlySnipes]

Only tune I want on my G80 is from Steve Dinan. I just listened to his interview on TheSmokingTire podcast and his comments about tuning were very interesting, makes me question most tuners.

[@WhatsyourForte]

Dinan is conservative so that is why people don’t use them. The only benefit is that you can buy the matching warranty. I don’t think they are doing anything special. They just give you a little bump safely.

[@FreshlySnipes]

@@WhatsyourForte you should Check out his podcast interview. He goes into depth about how to do the tunes w/o damaging the engine. Apparently a lot of tuners don’t know how to do that.

[@SALL73099]

Amazing video, appreciate your explanations! Quick question about the difference between efficient and sport +. So even with no tune, leaving the engine in efficient will produce more power?

[@WhatsyourForte]

I don’t think so. Only with the piggybacks would you have this issue

[@SilkySmooth02]

Numbers increase is about the same on my stinger......healthy numbers.

[@WhatsyourForte]

Yep… those stingers are no joke… I really like the way they look.

[@rikwuest2352]

So....Dumb question...All the talk of HP/Tq improvements and Dyno's the question is does your 0-60, 1/4 mile and mid band/passing numbers really change significantly with the Race Chip? I would be very interested in trying a RaceChip but only if I feel and see the difference on the road. What say you? Thanks

[@WhatsyourForte]

You can definitely feel the power increase on the road. Racechip tested the 100-200km. They got 7.67 stock and 6.37 on top map.

[@WhatsyourForte]

0-60 times is going to depend on grip. Anytime you add power you need more grip to launch.

[@rikwuest2352]

@@WhatsyourForte Mine is a 2019 BMW x5 5.0 AWD so I am hoping grip is never an issue with brand new rubber on 21s, that being said I just took the plunge and ordered a RC Black with app! RaceChip is having a flash sale (no pun intended) and they were 20% off! Your video, 20% off and 30 day return policy made it a no brainer. Looking forward to see what $700 buys me in way of performace.

[@c.m.8561]

Really REALLY good analysis putting the Racechip up against the JB4. There are a lot of variables that also need to be looked at and I feel like you touched on all of that. With another dyno on your car with the racechip in efficient I think we will be able to see a better overall picture. These cars are just not consistently responding the way they should be. We need a piggyback that is able to consistently put up higher numbers on the most aggressive driving setting. I feel the same about running “E” I will never use it so I’m more interested in what the car can do on 93.

[@WhatsyourForte]

Thanks. Yeah I plan to hit the dyno again soon. I think with the way the piggybacks work you will never get 100% consistency. A true flash tune will be the best option.

[@shannontuttle5754]

Id be very curious on the numbers if he had the exact same mods as you. Having a down pipe could very well level out that spike..

Going back on the dyno this Friday. We shall see

[@Sinister4202]

I thought on the jb4 you cant go map 3 with 93 ocatne? Dont you need e30 for that. isn't map 2 the highest for 93 octane

[@travvo2825]

Great work this seems safe to do both JB4 and race chip with out causing long term issues. I still dont understand how NVM mabz hitting those numbers with race fuel is it actually sustainable long term or disaster waiting to happen 🤔

You would only need to run one or the other. NVM had an unlocked ECU so he is able to tune the car.

Great video bro....and honesty and clarity. Being this is now 19 months later....if you were doing a Piggyback, would it be JB4 or RC Black GTS for a 2022 M4 Competition Convertible? Also due to convertible and not wanting any fumes in the cabin, what is best 'bang for buck' mod you would consider to enhance power somewhat? Appreciate your wisdom and advice.

[@WhatsyourForte]

Thanks. If I was doing it now, I would go Dahler or Racechip for pump gas and if I wanted to test out E I would do JB4. These are the best bang for buck mods you can do.

[@magicalretard2]

Can BMW detect the jb4 or racechip when taken in for warranty work ? Even if you removed it before hand

I have been told if they want to dig and do enough research I think they can. They can only deny warranty work on the engine at that point. I am not worried about the engine on this car.

New to the performance world. I have a 2020 Q50 Silver Sport. Since I don't have any experience with maps (just actually learned what the term means), would you recommend a racechip instead?

Racechip is a little simpler to use. Since this is your first time, I would recommend them over JB4.

Your RaceChip runs had more smoothing applied than the JB4 runs, the JB4 seems to spool almost 500rpm faster, while not being turned all the way up. I'd say the JB4 wins all day, but that's just my opinion.

[@WhatsyourForte]

So if you look back at my downpipe dyno video I posted the same dyno chart on smoothing 3 just like the JB4. The Downpipes really smoothed things out on the chart. I have to re dyno again in efficient mode as all of my runs where in sport plus and as we see you don’t make as much in sport plus. Once I do that, we will have a better picture of what is going on.

[@DanJLeh]

@@WhatsyourForte I'll be interested to see what's going on. Before JB4 came into beta RaceChip were really out pushing their product quite hard on the forums but when the JB4 Beta program released they disappeared. Happened to early MQB as well, can't believe I've seen it happen twice. They do a hard push early to get their cash while the true competition is sleeping, there is a reason there's only really flashes and JB4'S on the dragy leaderboards.

@@DanJLeh What "Dragy leader-boards" are you referring to? The one in the BimmerPost forum (g80.bimmerpost.com/forums/showthread.php?t=1855856) only has 5 (presumably running JB4). Additionally, most people going for the RC just want the extra power without trying to push the engine with the JB4 and the different ways you can tune it. Therefore, their interest to be in the "leader-board" would NOT be there. I personally would have bought a JB4, but the opportunity presented itself where I was able to get an RC for less than 1/2 the price. Not bad for just wanting to get rid of the EPA and emissions restrictions and open the S58 up a little more.
