Thanks in advance for any help

Yes, for a clean install you need to remove the front bumper. Others say that they did the install without removing the bumper but they must have tiny hands and care nothing about cable management.

You can use the instructions from the corksport intercooler as a reference on how to remove the bumper.

Can't get a good MAF connection. I've tried shaving down the MAF connector on JB4, no luck at all, car throws codes. Any suggestions? Just wait until good plug is available?

Edit: also, JB4 harness appears to have 4 wires for the MAF and car has 3. Did I get sent a CX one by accident?

Take two standard 8" zip ties and bind them together by the tail, and wrap them around the intake duct on the left side of the airbox, and up to and between the 3rd and 4th MAF wire to the right. Snug it up. That has kept mine seated and fully functional for over a month.

Edit: oops, didn't notice your wire count issue. regadless, if that MAF plug is still supposed to work, the zip tie anchor method will work.

Best to email me some photos for tech support, terry@burgertuning.com. No zip ties or anything should be required to attach it. It just clips in.

My MAF harness clip was visibly hand cut. When I pushed it down onto the 4 pin receptacle, the back half (toward the firewall) expanded outward, allowing the clip to descend and reach the pinouts, but at no point would it ever click/lock in place. I had to use zip ties or remove the MAF component completely.

I'll send pics tomorrow morning. Neither one of JB4 connectors click in.

I actually installed without removing the bumper, and i can assure you i did a really good job at cable management, my hands aren't that big either, i just removed the small plastic cover in the bumper and with the help of a flathead screwdriver i removed the connector, it took some time and pain to figure out how to reach and disconnect but it worked.

Dumb question, as I'm sure this has probably been asked- what is the difference between the two Mazda 3 Turbo firmwares for the V2 JB4?

JB4_P3_MAZDA_2_T1.hex and JB4_P3_MAZDA_3.hex? I mean, other than the _2_ is "stable" and the _3_ is "beta"?

That's cool. You should take pictures and help the community out. I think I take for granted that a bumper removal isn't a big deal in my mind. I rather remove a bumper than worry about figuring out how to reach something.

v3 is the BETA firmware. Changes are noted in the app, main difference was to the MAF tuning with v3. Now that intakes are heating up for the platform, including the BMS intake we're developing, we'll have a v4 firmware soon that features some addl MAF adjustment which is very handy when it comes to dialing in intake changes as the platform is fairly sensitive to MAF readings.

This is the best news I'll hear all week.

Terry,

Did someone volunteer to bring their CX-5 by the shop or do I need to figure out how to drive cross country? I understand the demand for the 3 to get first release but wondering if the CX-5,9 is on a similar time table for development.

Thank you!

We haven't had a chance to work on the V1 MAF control yet but it's still on our to-do list. We've got a couple cars relatively local when we're ready for it.

This is HUGE NEWS, stoked for BMS cold air, is it going to be a cold air intake or SRI like CS? Also will it have a heat shield? Holding off to wait for the BMS and avoiding rushing into an intake without a heatshield...

Why are you so excited about a CAI, when typically they are more prone to hydro-lock, and a SRI feeds near ambient temps to the turbo... which promptly compresses air to nearly 300F, and is then passed through the intercooler to achieve near ambient temps.

Just drove my brothers 2019 2.5t cx-5 (no jb4, on 86) and im honestly very surprised the difference between that and my cx-30. The cx-5 definitely feels more sportier and the power delivery is very different in my opinion, it feels like that of my friends q5 but i could be wrong. This might be a silly question but are the 2019 2.5t and the 2021 2.5t sky active engines different in any way?? cx-5 also had a different tone on the low end. just curious

Yeah the sound is insane, probably with any intake. Might as well get some power added while you're doing it though.
