Digging up an old thread here I know, but it was all I found when looking for info on aftermarket TPM systems, so...
So has anyone taken the steps to fit one of the aftermarket Tire Pressure Monitoring Systems? And if so would you care to comment on your research, purchase and operating experience?
There seem to be three main players. Hella's TC-400
Orange Electric's P409S
And 3rd Eye
also offers a system that can be had for
Note: SmartTire, one of the pioneers in retrofit systems no longer sell or support passenger car systems
, though I wonder why one of their RV systems
couldn't be used if you wanted to.
Orange Electrics seems to be dedicated to TPMS system research through racing and other avenues, and supplies sensors for a large number of OEM systems. This would seem to indicate a level of refinement that may be a step above some others. Their Display also allows all four tire pressures to be displayed at once, but is a bit big and clunky looking in my opinion. I was considering mounting it in the drop down sunglass holder, since my shades don't fit in there anyway...
Hella is of course a long standing player in the vehicle electronics field, and also supplies a number of OEM's, though it is my understanding from reading around that their system has been redesigned due to issues a couple of times. The Hella Display only allows one tire pressure/temperature to be viewed at a time, and has a separate control box that needs to be mounted within the vehicle, in addition to the display (and there is a connection wire between the two that has to be routed throughout the interior as part of the install). It also has a feature the others don't seem to called 'fast loss' warning, which gives a separate warning if pressure loss per time interval exceeds a certain level. Again, not a fan of the display design aesthetics, and would likely mount in the sunglass holder again..
The 3rd Eye system seems a bit sketchy based on their home website, and limited distributorships. Maybe it is just me, but I'm concerned as a result about its reliability, particularly from the standpoint of the stem sensors. Their display also shows only one tire's information at a time, however, it is the slickest looking display in my opinion, and looks like it could mount nicely right above the rear view mirror and almost look OEM...
The Schrader system looks to be very similar in Display layout as the 3rd Eye system, but in a standard box style enclosure instead of the sleeker 3rd eye enclosure.
Open to any and all experiences, and even opinions. Thanks...
