Hey Guys, hoping someone can help me out.

On two separate occasions now, my car has broken down with a flashing red cat temp sensor light directly after being nistuned.

The first time we thought it was the ecu, so we replaced it with another stock ecu. The car drove fine stock, a week later I had the nistune chip transferred across and the same problem occured a day later.

I'm convinced the nistune somehow has caused either the ecu or the sensor to malfunction. Or maybe the nistune chip itself is faulty?

Can I remove the sensor? What else could possibly cause this issue? Has anyone else had similar problems?

Thanks.

run stock ecu diag from the consult port

or plug in nistune and surely it has some sort of diag?

apexi powerfc has the hand controller with on board diag and sensor display :merli:

surely nistune has some sort of diag if consult doesnt work (it should)

Its going into limp home mode. Check the nistune board is still held into the 20 pins correctly. Also check the 4 wires for the board are connected.

Check all solder joints. Check that the board has been hot glued so it cant come loose.

Where are u located?

i think we got a bung board :(

No diag faults logged and weird delivered timing, swapped out the board tonight so fingers crossed its fixed...

Very odd as we have never had a board fault in 4 odd years... always a first though.

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.

      To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all

      300kW is so boring in a Skyline, you'll get spanked by someone's mum's Golf with Alibaba pipes, and an email tune.
