    It's because the TPMS system is a very simple one. Go off at 28 PSI or when a sudden decrease of pressure is noticed.

    Luckily, we can easily disable this using etacs decoder if wanted.

    Are you sure? I thought Vlad said he doesn't do TPMS.

    I think he just doesn't support it.

    I can turn it on and off with the decoder I used to program fogs and cruise.

    Changed oil & oil filter.
    Installed Mobil 1 0W-20 Advanced Fuel Economy & Mobil 1 Extended Performance oil filter.

    I really like that Fumoto valve. It makes oil changes very convenient.


    I noticed something interesting after doing the oil change. While running the engine to circulate the new oil I took off the oil fill cap to observe the valvetrain. The engine RPM began to oscillate. Once I secured the oil fill cap back in it's place nice and snug, the engine idle smoothed out. Has anyone else noticed this?

    Yes, when you remove the oil cap, it opens a vacuum leak into the engine thru the PCV system. Because the cap is off, it isn't a closed system any more & you have introduced unmeasured air into the engine that is not going thru the MAF.... It is the same as a Vacuum leak... Hope this helps...

    Yep, makes sense. I don't recall if anyone else noticed this though.

    I added a bottle of Techron fuel injector cleaner with yesterday's fill-up. Thanks stevedmc for the tip.

    Speck runs better with 0W-20, contrary to what others here have shared. Cold start valvetrain noise is both quieter and shorter in duration. Regular engine operation is quieter as well. Unless its not available, I'll be sticking with 0W-20 from here on out.

    I've also been interested in filters from Champion Labs, the company who makes filters for Mobil 1, among others.

    I aired up the tires and took Speck out on the road yesterday - about 300 miles round trip. The odometer is now past 27,000 miles.

    Averaged about 60 mpg according to the MID-A computer. Not too shabby, though I doubt it's accuracy today more than usual. I'm hoping some miles like that will help bring my lifetime average back up in this warmer weather as it takes a hit in the winter months.

    I am enjoying the heck out of this little car.


    P.S.: Now that I've updated my Fuel Economy Log, my suspicions are confirmed as the MID-B calculation for this tank was optimistic by about 5 mpg. It's averaging 2.2 mpg optimistic lifetime. I've noticed larger errors when coasting, though I didn't really do that much coasting on this trip. Go figure.

    Exclamation F.A.S.T. key (KOS) battery replacement

    Nearly two years after noticing the first signs, I finally replaced the battery in my F.A.S.T. transponder key. All is well now.


    Here's how it went:

    1. Upon engine start the dashboard Immobilizer symbol would flash on and off upon reading the transponder code, indicating a low battery condition. I first noticed this in September of 2017. For over 18 months, all other functions worked as expected (lock/unlock doors, engine start.)

    2. A few months ago I noticed that I needed to be closer to the door buttons/antennas for the F.A.S.T. system to read the transponder, indicating the signal was getting weaker.

    3. Sometimes, especially in the morning when the key hadn't been warmed sitting in my pocket, the key wouldn't be read by the driver's door but would work at the hatch. No big deal. Sometimes it would work at the driver's door if I set the transponder key adjacent to the button and/or push the button using the key. But it would work reliably at the hatch.

    4. Then it wouldn't work at all at the door but still would work at the hatch, even in my pocket. It would work reliably in my pocket once inside and sitting on the driver's seat. This would have been a good time to replace the battery.

    5. For the past month or so signal strength degraded to intermittent operation when unlocking at the hatch, especially in the mornings. I would sometimes have to use the hardware key to unlock the passenger door, then unlock all doors using the inside button. Not having a security system made this less embarrassing. Enabling an engine start began to work intermittently from my pocket so I would bring the key out of my pocket and move it closer to the antenna located at the center console. It would still always work from the F.A.S.T. key storage in the car's center console.

    6. The past two weeks, the key would not work at the doors and needed to be brought closer and closer to the interior antenna in order to allow engine start. The transponder code would not be recieved at either the door or hatch.

    7. Yesterday I felt I was lucky to have started the car and get to work in the morning as the only way Speck would start is if the key sat in the antenna location in the center console. It was good to see the immobilizer light flash on the dash once the code was finally acquired. Time to put in that new battery.


    So there were Lots of signs along the way of the F.A.S.T. key battery health. Until yesterday I never worried about not being able to use the car and the system worked as described in the Owner's Manual.


    I haven't been driving Speck much in this nice weather as it is more of a foul weather / winter beater for me - a special tool for particular jobs if you will. If I had let this little experiment go much longer in between use, may I have been stranded? I was never worried about it until yesterday. In conclusion, I got another 22 months use out of the original F.A.S.T. key battery after noticing a low-battery indication on the dashboard. Other than that, nothing of interest to share.
