    OBD2 Scanner/App: what sensors/values to monitor?

    I’ve gotten 40’ish mpg on some long drives as well(6-10hr), same oil brand/type/oci. I made the call since the beginning to do frequent oci with affordable oil & filter given the driving the Mazda 3 does. Next factor would be location weather, I haven’t checked the parameters during the summer...

    DIY Morimoto XB LED Fog Lights installed

    @nhluhr Can you share a picture or short clip of the fog light in action. I might go this route as well vs oem housing with yellow led bulb, its below average.

    2016~2023 8" speakers fit perfectly in the CX-9 doors!

    I can't say much about Linear Power, especially since there's almost no reviews online. If it wasn't for you mentioning I'd never known they existed.

    Interesting observation when charging battery

    What accessories have you installed since you've had the car, some accessories do drain the battery. Either way you can check for battery drain, check youtube for examples and try it yourself. Check if battery voltage when in idle is 14 to 14.5VDC

    OBD2 Scanner/App: what sensors/values to monitor?

    What's your engine OCI and what weight do you use. In my case atx and engine oil temps are close to each other. I change engine oil every 3.5k/4mo SuperTech 0W20 Full Synth as it does more short drives around the town (35%hw/65%local). Record some data and share it if you can.

    2014~2018 Mazda3 OEM Big Brake Upgrade

    First thing I upgraded on 16’Mazda 3 was the springs on stock shocks & struts, got the racing beat and it made the car much better and enjoyable but not harsher. I’d recommend these springs to anyone if you want a great daily oem plus upgrade. Next upgrade will be bilstein B4 front and rear...

    2014~2018 Mazda3 OEM Big Brake Upgrade

    Interesting development, I was planing to upgrade the front brakes with a set of rx7 4 pot caliper and the 295x25mm rotors. Have the rx7 form a trade few years back and as I noticed the front brakes need an upgrade what better than rx7. Surprisingly the mounting location of the rx7 caliper is...

    2016~2023 8" speakers fit perfectly in the CX-9 doors!

    How are the rear doors holding up with skar 8" subs ? You got some mix of selection there, how do they match up ? On my 16'Mazda 3 (base speaker system) I've replaced stock dash twitters with "middler" 3-1/2" pioneer TS-A879 and front and rear doors with Infinity reference coaxial 61/2"...

    OBD2 Scanner/App: what sensors/values to monitor?

    I got vGate vLinker MC obd2 which would work with my triumph motorcycle as well. Been looking at Forscan, might get that but in the mean time I'm using the Car scanner app and tracking some aforementioned engine parameters. I've noticed the only voltage reading is that of the PCM and its max...

    Technically yes, as long as it has same width otherwise use an online wheel calculator to check for discrepancies.

    OBD2 Scanner/App: what sensors/values to monitor?

    Which obd2 scanner/app combo you're using, I'm thinking to do the same for 16' mazda 3. Temps and voltage are easy to monitor, most engine parameters are best data logged then reviewed afterward until you find a set of parameters to review live. It gets cumbersome to review live engine...

    What have you done to your CX-9 today?

    I always ask for print out of the alignment, you'll have something to compare before and after.

    Oil Change after only 2k miles in the past year

    It's cheaper to change engine oil especially since its been in use for about a year even though you've driven less then you could've vs letting diluted engine oil sit for longer period of time.

    All New 2026 Mazda6e Driving Review

    The review is pretty honest but I'm not feeling this one with just Mazda skin but otherwise not a Mazda vehicle. Would skip this model for sure.
