Do you have any specific concerns when it comes to removing the bumper? What is your experience with turning an automotive wrench?
I can do my oil and that's about it lol. My buddy, who essentially rebuilt a toyota soarer (the only thing stock now is the body) helps me with most of my stuff so I am learning. We just took the bumper off the other week for the FMIC upgrade from corksport, so taking it off isn't truly an issue. He just dislikes body work because of the relining of it lol.

I did watch that video but for some reason it taped to a desk doesn't quite seem the same but thanks

Both times that I have had to open the unit after install one of the screws/nuts on the smaller connector have vibrated loose. I am certain that a bouncing loose piece of metal near a circuit board is not a good thing. I had no loctite around, so I wrapped the connector in electrical tape to prevent the nut from coming loose in the housing. It may be advantageous to start using nylock nuts for this use.

On the blue tooth enclosure? Never had that happen or heard of it happening. You can always delete that cover all together, no one can see it with the enclosure closed. It's only on there for JB4 models that have an exposed DB9 connector.

Yes. The Bluetooth adapter serial plug. Has happened twice. The captured nut does not remain captured. When I get back to my TN home, I will raid the hardware drawers for the right nylock nuts.

Just remove the shell it's purely aesthetic anyway. A year ago it wasn't even there.

Thank you Terry. I appreciate the low tech solution. Keeping it simple works for me.

It isn't finished yet. I think John getting more than 40 hp gain once it is finished and everything is stable. From what I am seeing right now this engine is making 300+ crank hp and 350+ lbs of torque with the jb4 which is impressive enough. this thing will be a mini rocket once it's finished. The mazda6's will be a fwd burnout machine as well.

The only things guaranteed in life are death and taxes.

But the dyno reflects what we've been able to make on the current mapping, and there is plenty more potential in the platform we're working on unlocking.

Does 91 Octane Vs. 93 octane make a large difference in the whp and wtq? Sadly cannot get 93 Octane where I live...

You'll make more on 93 than 91 but if 91 is all you have you'll still make a lot more power than stock with the JB4. Maybe you have E85 access to mix in? That gives you > 93 octane performance.

Is the JB4 for this platform undetectable like on a MK7 GTI? I've previously had a JB4 for my MK7 GTI and interested in this for my wife's 2019 Mazda3 AWD Turbo.

Yes no trace left behind when removed.

Will I still be able to pass the NY annual inspection when I have the JB4 installed? Will it affect emission? Btw just got my JB4 today.

You'll be fine......Just don't say anything and they won't ask anything....... If you're seriously worried just disconnect it during inspection

Yes, the video referenced is terrible. For the CX-5 owners that are dead set on not removing the bumper, the video is explaining that to the right of the MAP sensor is a plastic air dam that is removable. That will allow you to reach into the MAP sensor from the intercooler opening in the front bumper.

Having removed the plastic air dam with the bumper off, there is a real chance of damaging the rivot that holds it in place. I like to keep things installed cleanly so I opted for the bumper removal so I wasn't cramped or pulling rivots out without a proper tool and angle.

Terry, does adding E85 also apply to the CX-5 in regards to making more power?

No, have you been able to locate the installation instructions on the product page? They are very informative.

Do you have 93 octane available to you? If yes, then it isn't worth the hassle of mixing to E30. If you only have 91 octane available then it is worth the effort to mix to E30.

That is only my opinion as a CX-5 owner.

I've seen a few Mazda3 logs with those settings all at 0 which would limit your performance.
I just want to make extra sure before I go changing anything, I should be putting 25 in each of the lines on the fuel bias column? Everything is blank on mine right now.

Thank you for the input. No 93 where I live but there's an E85 pump around the corner from me.

Yes on your fuel bias question. It is weird that everything is blank though ...

Even your settings below the table is blank. This is confusing
