I upgraded my firmware to 1.17 and switched the sensor over to 4.9. It lasted about 3 months and died.

Also, innovate says that if you unplug the sensor while the control box is powered it will kill the control box.

They finally emailed me back for a repair and gave me an RMA number.

Ive been running an MTXL for about 18 months and 20k kms. Still running fine as far as I can tell, the gauge is very responsive.

As above, it connects digitally to the adaptronic ECU, and is recommended by adaptronic themselves. That was a simple enough choice for me.

So are all the installations a new bung welded at least 1 metre downstream in the exhaust? Is the sensor tip pointing downwards as much as possible? On the stagea at least it narrowed it down to only 1 location: just before the cat (almost at the flange of the dump pipe) pointing up into the cavity.

There's also the sensor type. The MTXL seems to be upgradable to the LSU 4.9 sensor. Im just running a 4.2 sensor and it works fine for me. Im going by the principle of "if it aint broke don't fix it".

Those are some things to try before writing off the unit. Maybe there is an internal design fault. It does combine sensitive microcontrollers with high current capability, that's always a fun mix.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
