No reply from Terry or anyone from BMS, what to do now? Should I send the unit back? Can I get refund?
I am experiencing the same thing on my c63 after jb4 install. Random misfire codes , transmission codes , car randomly revving itself to 3.5k on a cold start, etc. They sent me a replacement board because the original board was getting wet due to water getting in the case. However , after replacing the board the issue continued so $1000+ down the drain with a useless board.

Misfire codes can certainly be from running higher boost levels, as for the rest I don't see how it would be related.

I have several emails going back and forth with Payam and Jon. Iíve swapped boards ,installed fresh plugs , fresh coils and dealer replaced bad injector on cylinder 8. At the dealer i asked them to run diagnostics on the trans since the jb4 was throwing some really strange trans codes , everything checked out fine at the dealer. I never had any issues before the jb4 and I donít have any issues now after removing it.

And did these faults and issues crop up on JB4 map0?

Are all codes thrown while the jb4 was in the car. Sometimes even just cruising or partial throttle.

Terry , that is no different then removal the jb4 all together. Point is , jb4 out of the car i have zero issues. Jb4 in the car , all types of random faults. I may not be a tuner but i work in the IT field and i am fairly comfortable working with electronics and technology in general. You guys are having issues with these jb4 on the c63 and donít want to admit it. I am not the only one reporting issues with it, i have other products from your company including a jb4 on my single turbo 335i and i have zero issues with any of your other products, but this c63 jb4 is crap.

Exactly what was happening to me, ezatnova and other users on mbworld forum who was PMing me... I was assuming that JB4 for my C63 would be good as I hear from BMW friends.. its not.. When it was in my car I was having issues, spend so much time worrying, without car which was in service etc.. I dont trust this product anymore. Its rubbish and I am SCARED to sell this to anyone.. Refund? Forget about it...

I will attest that I have had no issues with the JB4 on my 2018 C63S. I have had it on my car now since June and about 4k miles and have pretty much ran all maps except map 6 with no issues or codes. I had the JB4 on my 2013 BMW 335i from when it had 2k miles on it after taking delivery in December 2013 till when it had 115k miles on it when I sold it in March. I hardly had any issues with it. It ran like a champ. All I have noticed with the JB4 on my 2018 C63s is a slight stumble during idle and that's it. The car drives like stock but with significantly more power and torque especially in Map5 with E30 in the tank. I messed around and added the pedal tuner last week and this freaking car is insane! I'll play devils advocate here and simply say that it's not quite fair to say its JB4's fault because after you removed it from your car, your issues went away. Always go Map 0 or remove the ODBII connection before removing your JB4. It could be a connection issue a defunct board. You just have do some troubleshooting. Over the years, I have learned that a bit of patience is required while using aftermarket products with your stock car.

You clearly did not read the post where i stated all the troubleshooting that was done. Including a replacement board.

I bought this unit in its Beta stage , I wasnít expecting perfection but this specific jb4 is paperweight.

Yes, it is. It's a diagnostic process to isoalte whether your issue is hardware related or software related.

We have around 250 of the C63 JB4 systems out around the world with overwhelmingly positive feedback. It's also true there are 3-4 of you guys floating around here with issues. You're the only car I've heard of with "lots of faults". Most of the problems that we've seen are misfire codes which are somewhat expected at higher power levels. So how we diagnose your specific car is different than a misfire code situation.

We're happy to provide technical support for anyone that needs it, including replacing JB4 hardware if it turns out to be faulty. But being in tech support I'm sure you can appreciate diagnostics is a process. If you take a short cut and skip steps then the whole process has to be started again. Given the diagnostic codes you are throwing seems like it has to be a hardware issue so that is why the map0 test would be critical for your situation.

Your experience is the same as the vast majority of customers. Of course, when issues do crop up, we're here to help get them resolved as soon as possible. Although it's a two way street so customers do need to engage us in a productive way if they expect us to be able to help. In the two situations in this thread I suspect they are both hardware related issues, maybe water damage, loose wire in the harness, broken wire in the OBDII or loose OBDII, etc. I'd encourage them to send the systems in so we can test them on our development car, find the issue, and provide them with a new JB4 which they can reinstall or confidently resell if that is the route they want to go, or store credit for other BMS products if you prefer.

Ok, so lets say i send you guys the unit and you test it in your development car , this would be the third time i would have to reinstall this on my car. The install is quite the pain in the ass and luckily i have the knowledge and tools to install this on my own but do you expect people to pay $200-$300 to install the jb4 every time?

My jb4 had a scary amount of moisture in it the first time, which is why you guys sent me a replacement board. How is that something i should be held accountable for ? Is it my fault your product doesn't seal correctly?

Does it currently have water damage? That would certainly change the trajectory of how we diagnose your issue.

The enclosure is water resistant. If water is getting in that's a big problem we need to resolve.

If you want to open the enclosure to confirm and email in a few photos, or just send the JB4 in and we'll replace it for a new one or store credit towards other products on our site for you.

So. can I send my jb4 back to you and get refund, no credits, what would I do with credits?
If you really have only 4-5 not working units from 250 it would be nice to do it.

I am not going to install it again, I spend much more money for install, plugs, tow, dealer remove, ECU reflashes...

As you've been told it doesn't qualify for refund. Exchange for a new JB4 or store credit. We've got a C63 intake. Other products for other cars friends or family may have, etc. Just offering it as a courtesy as policy is exchange for a new JB4 only.

I don't understand the rationale here. Those are sunk costs at this point. Seems like with where you are in your options you would want to exchange it, have it installed (by someone else this time), and see if it works.
