because from what I remember the oil pressure gauge is connected via CAN with the main cluster then to the ECU and the electrical flow path goes from the passenger side wiring harness. and not the driver one which is mainly for the ABS/brake booster/lighting aera.

I'm using an aftermarket oil pressure gauge with a dedicated pressure sensor...

It has not been started yet

It is possible there is something deeper involved. We're going to address the harness first, then we'll see!

Seems like the low oil flasher came on pretty much simultaneously with the engine dying. Engines make zero oil pressure at zero RPM, and hot oil at very very low RPM in the last split second of engine life might've had naturally low pressure, too. I bet after the wiring harness is fixed you're fine, especially given you had some cool-down time while the engine was dying. Good luck!

Thanks! think / hope you're right

Yes I have no fender liners. I will be double checking that. Great video Travis I will be watching this a lot. Still going over my videos. My best time as of far is 1:46. I'm just happy to get threw the first weekend in 10 months with a hole different car.

Also nice to meet you again.

travisjb · 02-23-2014, 08:37 PM

That's a respectable time and I saw you out there consistently passing cars at start/finish, and moving your braking point downfield at turn 1. Nice driving!

Great to meet you and your dad! I owe you guys some beers for helping to push my z back in the trailer.

Mike · 02-23-2014, 09:20 PM

That was Sharif you were following. Glad to hear its probably just a harness. Spohn told me you had troubles.

Going to NASA next month?

travisjb · 02-23-2014, 09:27 PM

hey mike. not sure what my next track event will be - really want to get back to VIR to see how the new pavement works out... will miss the chin event in two weeks, unfortunately

carlitos_370z · 02-24-2014, 07:02 AM

Damn travis good runs bro!!! sorry to hear about the mechanical problems that you have!!!

wstar · 02-24-2014, 09:02 AM

So, what's the tradeoff on removing the fender liners? (well, aside from the now-obvious wiring caveat!). I hadn't considered it before. Better airflow around the brakes, but you get some more splash into the bay on wet track days? Doesn't screw up radiator airflow or general aerodynamics?

travisjb · 02-24-2014, 08:45 PM

Hey Brandon. I don't recommend removing them for the reasons you state relating to preserving oem flow through radiator and also because less airflow around the tires = less drag. Best to avoid for those and other reasons. In my case, reasons we removed because remove/replace choir was a PITA, were wearing them out, had been hacking them up for mods like 3" brake ducts and others constantly anyways, and a lot of the front end was redone so OE attach points gone, relocated, etc. They were hanging on for dear life and put them out of their misery.

travisjb · 02-24-2014, 08:46 PM

Gracias, Carlitos!

carlitos_370z · 02-25-2014, 05:57 AM

i hope to run my car like you someday bro hhahaha!!

Megan370z · 03-04-2014, 08:14 PM

Hey, hows the engine ?
We havent got any new since it died while being on the track

travisjb · 03-04-2014, 08:25 PM

Running. CIN thinks it was a mfgr defect in the battery causing havoc with electrical system. PC680.

Wiring harnesses also reconstructed and re-routed so no longer at risk of contacting tires.
