Please clear one thing: Could this USB TPMS system work with more than 4 sensors?
There is some promise in this thread but they are too old.
On the one side (about COM-110 in mp3car store) "...Please note: The TPMS system can only support reading 4 tires at once", and another side there are a lot of examples and skins for front end software where shown this system working with 4 tires AND spare.
How long should the learning process take, mine took > 30 minutes for each and was reporting garbage data. I wonder if I messed something up.
I just moved it back into the original holder and it's still taking a while to read.
I think something is broken then, because TPMS doctor says it's connected, but when it actually does learn a tire the readings are wildly erratic 55psi, 178F ?! Could I have messed up the receiver when I cut it?
Do i have to change the tire pressure? The sensors are installed on my tires so they're transmitting, I was getting good readings just before I hacked up the receiver.
So I'm waiting on a reply from robby, but I wanted to ask the masses. Has anyone had trouble with their setup? I soldered up the hacked apart board to reference tpms board from robby, and as above it only occasionally gets signal. I checked with an oscilloscope and there's data going to the PIC chip, but it won't learn the sensors.
I only see at the MP3 store the entire system or a single valve for sale.
I'm interested only on Robby board with the PIC chip, I got the system while back from an online store. Anyone can guide on how to buy the custom board ?
