I see that you are running E43. What map are you using for that amount of ethanol? And what would you recommend for e30 mix? I've tried map 5 and feel WHOLE LOT of more power but only for short time because I was unsure. Currently at E30 + Map 2. Would appreciate your advice. Thank you.
It’s very difficult to void a warranty off a piggy back. Yes it still can void your warranty but very difficult to prove. Enjoy the jb4. Definitely a great buy.
Hey there nice video! Just got my JB4 installed in my 22' M340i and to me, what AFR are you running during WOT?! E30 mix with Burger cold air and AWE exhaust my AFR was 14:1 to me seems way too lean to boosted. Any idea on this or is this normal for Direct Injection engine.. what AFR during your pulls were you running?!
Thanks! I get around the same values, maybe a bit lower running 93 on map 6. JB4 can’t read e values unless your running an ethanol sensor and white wire to the jb4 so values may not be true running E. Run a log and send it to jb4. Email and instructions are on the webpage. They’ll help out a lot.
@@justj3rry thank you replying back to this. I sent a log to JB4 in 3rd gear wot and they said it's normal. I can't see how 14.1 AFR on a boosted motor is normal! I can try running map 6 with 93 octane like you said see how it does
Check engine will always pop up unless you get a proper tune. You can clear the code with Jb4 every time it pops up but it won’t keep it from happening.
Thanks! Appreciate the support. The front lip I got off eBay. I’ll try and find the link for it and post it in the description. Also I’m gonna make a video on all the mods I have on the car. Stay tuned!
@@justj3rry which would you recommend if I'm just looking for a little bit of extra power, while staying stock on 91 octane. I might get a dp in the future but more for sound not power. I don't understand the maps for jb4 like which one I can run on stock, map 1 2 or 3 or?
Yes. They are different stages 1-5 depending on what mods you have and what gas you are running. Map 6 will be a custom map. It’s on the jb4 website with a detailed description.
Dope video 💪🏿 I just got my 540 thinking about going the jb4 route , The video in motion video with bimmercode was dope to you think you could hook me up with that ?
Thanks! Watch my BimmerCode video. The process should be similar for your car. The link for the obdII reader is in the description box and you’ll need to download BimmerCode.
