Rusty needed new shoes as the old 205/60/15 Kumhos were wearing out so I obtained round-about wife-approval needed for new rubber. I wanted a stiffer shorter sidewall, larger contact patch and a more agressive stance so I ordered Falken 225/50/15s.
The old tire still on the wheel and the new tire. I had them mounted and balanced at Japtrix Racing in Riviera Beach after ordering them on vulcantire.com
New meats.
Z-Mom ordered an LC-1 Wideband O2 sensor for son 280z-hab. The installation was fun an will turn me into a data-aquisition junkie.
The instruction manual called for the 02 sensor to be mounted at 12-oclock in a place unobstructed for the upwards pointing wiring with easy access into the cabin. With the Z up on stands it looked like right next to the transmission between the header flange and the glasspack was perfect.
Indy double checking my handy work.
While I was at it, I wanted to chase more surface rust and adress the wiring that I stuffed under the seats after removing the interior from the seats back. I chased more surface rust with wire brush/brake cleaner and then primed with Rustoleum rattle cans and painted a semi-gloss black.
Over on the passengers side it was the same story, I ended up removing most of the dash trim for easier access.
For the kill switch and the ground for the LM-1 and guage, I drilled a hole through the fire wall near the floor (look carefully and drill from the outside because clutch, brake, and fuel lines are routed in this area). You can also see my painting handywork, and I cut 2.5-inches off of my shifter for a ghetto short-throw shifter.
I spent an evening reading through the manuals and mocking everything together with labeled blue painters tape from the comfort of my livingroom couch.
And a mock up of the guage, the calibration button, the LED, my kill switch and my fuel pump cut-off switch. I had to remove the original Hitachi radio with the double dial-in knobs. I hate that I removed the radio, it really completed the old-school look and my next Z-project will be replacing the radio and re-locating what is in there now.
The soldering iron and getting everything wired together correctly. I ended up running the O2 sensor wire up the trnsmission tunnel and notching the shifer cut-out with my angle-grinder. This seemed to work really well (after priming to protect against rust of course!).
Carpet and trim back in, O2 sensor with the fresh-air calibration and the shift-knob securely JB-Welded into place. It is kind of ghetto but I have to admit that I like the way it looks and I can rest my arm on the arm-rest and the shifter at the same time.
Up and running! I am going to zip-tie the wiring for the LM-1 data logger underneath the transmission tunnel trim to get it out of the way. Notice how the AFR idel is at around 12...idealy it should be reading 14.6...so looks like I have some tuning to do!
I hope work doesnt see this...but I have my old work laptop hooked up for some real-time data collection. Right now I am just logging O2 but I have ports for TPS, and RPMs wich I need to hook up. Then there are calculators that will give dyno-like results for hp and torque...this is a really cool toy...I mean tool to use for playback and ultimately I want to figure out a way to sinc this with my in-car video for autocrossing so I can see corresponding data for shift points, accelleration, etc.
And a screen shot of the data logging playback feature...only O2 hooked up for now!
Removing the carbon canister. I seriously doubted that 30+ year old carbon had not suffered breakthrough. Plus my State does not require visual or quantitative emmissions testing (yet), and I wanted to further de-clutter my engine bay so out it came.
Now you see it...
Now you dont!
