Terry,
Will the CX-5’s JB4 continue to utilize the connection at the intercooler, or will further development see that connection point migrate north to the MAF? I’m not a fan of the work involved getting to the passenger side of the intercooler.

I figured the axles wouldíve gone first. What were you doing when it blew out?

You just select them in the app and email them, or you can also email them to yourself and attach them to a post here.

Was not accelerating hard just cruising. Nothing to do with strength that caused it to go.. Even the strongest diff would let go if it had the same issue.. My lash was not setup right from factory or a clip was not installed causing my pinion gear to move. looks like a one off definitely not a common issue..... Covered under warranty no big deal. Got a cx-30 turbo loaner till I get my 3 back

Yeah I saw your Facebook post. I wonít say Iíve been taking it easy on mine, but I now save boosted launches for ďspecial occasionsĒ rather than the regular occurrence they used to be

Don't get it twisted that because I have a Kia and you have a Mazda there is no correlation, there is plenty.

My car will run around 98 mph on 91 octane in the 1/4 mile.

It has run 102+ on E30 and 103+ with E and water methanol injection.

I run drag radials at the track so it should run high 13's on 91 now that I got my 60 ft times in the 1.9's.
I ran a FULL tank of E30. A week's worth of starting it up, giving the ECU ample time to "learn" fuel trims and apply additional spark, load, or boost. It did none of those things. I took regular logs. It might be best to know the product before chiming in

Not true. The ECU works in a closed feed back loop. Keeping the engine making as much power as the manufacture map will allow, many times a second trying to advance the timing till micro knock. Then the ECU dials back the timing a bit and the loop starts over again, advancing to a maximum point that the manufacture sets or micro knock. This maximum level can be varied almost in real time for different engine temperatures, throttle positions, engine loads and others inputs. The only way to over come this is altering the inputs data to the ECU or a tune.
The ECU is monitoring many times a sec as close to real time as possible. lol not some start up check that changes timing.

Gotta love the big brains trying to tell you what isn't happening with our platform... because it might be with theirs. Data is king, always. Making assumptions and telling people they are WRONG... laughable at best.

Not sure what you guys are arguing over but there is a high and low long term adaption range for timing, and this specific ECU also uses that adaption to modify it's boost target slightly, providing for a wide range of octane levels to be used from 87 on up to around 93 where it more or less maxes out from the factory. There is also a short term by cylinder "knock" timing correction factor blended in.

Pretty much what you just said - the ECU isn't going to exceed OEM 93 map timing targets simply due to the presence of higher octane. We'd need to flash the ECU like a typical Cobb / Mazda Edit map... or whatever voodoo you can cook up with intercepting and tricking the car further.

We're always going to need the 2 MAP connectors... The MAF will be in addition.

Default Jb4 tuning on or off - 10-27-2021, 09:37 PM

Hey guys. Iím new here so my questions may seem nooby. I got the jb4 for my 2020 Mazda 6 2.5t and I wonder, do I have to go in the app to turn it on every time I start the car? Or does it stay on constantly? The reason Iím asking this is that I noticed (and it may have just been my subjective observation) my car running normal if I donít get in the app and tap on the MAP to get it to map2. After doing all that and only then the chip seems to start working. Please let me know if itís me or this is how it works. Thanks!

I just tossed a K&N filter in mine as a stop gap until we've got intakes available that include a turbo inlet pipe. I might pick up ~5awhp lol.

My God 93@Map2 is amazing. Getting pas a 100mph is just too quick .This is already enough for my need. Just need that 80mm corksport midpipe then I am good.

Lol.. it's still a high 13s 1/4 mile car. I spose I'm extra jaded because I own a 525whp Speed3. I do really enjoy the 0-30 burst with a brake boost, and probably even more so when I get real tires on the car.

Roasting all 4 tires to ~5K RPM is entertaining, even if it's on bicycle tires.

I donít own a faster car but Iíve been in much faster cars so I agree completely. Last night I pulled a 1.9 60ft which felt good, but the rest of the run was nothing special. (8.7 in the 1/8th and 0-60 in 5.1, so good for this car but overall I wouldnít call it ďfastĒ)

Hi, also a newbie here

By any chance do you have pics of the installation process?

Y own a Mazda 6 2.5T and recently bought the JB4, but can't figure out if it is just a plug&play install that I can do in my home or should I take it to a car shop.

It seems that the setup is different in the CX/3 models than the 6.
Acoording to BMS instructions, there should be 2 MAP sensors to plug, and only on CX-30 a third MAF sensor to plug in

So in my car I need to find the manifold sensor that I already did
Name:  manifold.jpg
Views: 232
Size:  86.1 KB

And the other sensor should be on the chargepipe, I asked Terry and he sent me this pic (I can't find it in my car, at least not in plain sight under the hood)
Name:  cx_map_sensor.JPG
Views: 231
Size:  233.2 KB

And finally, the wire to the OBDII should be routed through the firewall
Name:  cabin.jpg
Views: 230
Size:  78.4 KB

My main question is, do I have to remove the front bumper to reach the chargepipe sensor? (second pic) If so, then for sure I'll have to take the car to a shop.

Thanks in advance for any help

MAX
