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.

    • Cheers fellas, I got a price for a r33 gtst box was 1500 including post and thought it was too cheap  
    • The SS button head cap screw on the back? If so, good to know. I presumed it was there for basic assembly and nothing more. 
    • Hello, everyone. I'm new to the forum. I have a 1989 Nissan Skyline R32 GTR. I have lost all power to the interior, including AC controls, the gauge cluster, turn signals, and windows. Stuff that still works includes the horn, brake lights, radio, and headlights. All fuses, in the interior and exterior boxes, tested good.  It starts and runs fine, just with no gauge power or anything stated above. No warning lights either. Things that I have tested: - Fusable link tested fine - No other fuses blown - Alternator good - IGN switch tested fine - With my power probe, I can backfeed power through the IGN pin to the plug on the back of the gauge cluster, and everything comes back on.    So my theory is something on the control side that sends the ignition power through the system isn't doing its job, or a wire is broken. (I would think that it is the ignition switch that would do that, but who knows?). The ignition relays don't fire (all relays tested good). So what tells them to fire other than the IGN switch?  I would really appreciate it if someone had some insight on this. I have tons of hours into this; I don't want to give up in defeat! I have the HD wiring diagram, but having all those wires laid out like that on one sheet of paper makes things pretty hard to follow.  Thanks for reading, and thanks for the replies.  Where should I look next? Thanks.
    • Install a MAP sensor pre and post throttle. Best data you could have for NA, then play with the bends and/or air box and see how much of inflection is created at WOT on the plot.
