Been putting this update off for a while since I've been insanely busy. Instead of elaborating in great detail on everything that's been done, I'll just share the pics and my build notes. Feel free to ask any questions or post criticism
My current tuned MSQ file for anyone interested.
Intake cam retarded 7 degrees!
VE Table incorporated into tune under secondary load parameters
- Injector Size: 750cc/min
- Processor: MS2
- Fuel Pressure: 38psi
- Firmware: MS2/Extra DIYPNP 3.2.4
- Temp. Sensors: Std. GM
- Board: v3.57
- Oxygen Sensor: Innovate WB
- MAP: 255kPa
WiFi antenna and switch wired up to toggle between BT and DB9 serial
Re-used fuel pressure regulator solenoid and wiring for VICS activation.
Homemade PVC VICS vacuum manifold because I didn't feel like chasing leaky rubber lines in the insanely difficult to reach factory spots.
Roll bar install. Robbins streamline one-piece just barely clears
Flyin' Miata frame rail reinforcements. Really stiffened the wobbly chassis up in addition to the roll bar.
Clearwater fiberglass subwoofer rear deck install and finishing roll bar trim.
Compression testing in the snow before my tuning appointment
Tuning at Xenocron by Matt Ivan and Chris Harris
*** Cam gear proved to be a great investment. Picked up 26WHP by just retarding intake came 5 degrees!
Mainline dyno = heartbreak dyno since it reads very low. Tuner estimates Mustang dyno will show 300whp+, either way I'm extremely happy with how the car feels. Note the dip at 6k is likely from the 2.5" downpipe.
Before her first auto-x event
Back to daily driver status. Averaging 21MPG city, 27MPG with 75% highway usage.
And a video I compiled together from GoPro footage taken from NYR SCCA test/tune last weekend:
Vimeo - PROJECT MEOTTER
General Output Relay 2 - VICS (PT6 Output, Pin 2R factory harness, 4R DIYPNP)
3/13/2013 - New fuel filter, bled brakes with Valvoline DOT4 Synthentic, fixed valve cover leak, disconnected LC-1 calibration switch due to short, wired in 4 2700uF capacitors for COPS, compression test: ALL cylinders 188-190psi
3/14/2013 - Dyno tune at Xenocron. End result 247.3whp / 215.8wtq @ 20psi Mainline dyno (closer to 300whp dynojet). Intake cam retarded 7 degrees (14 crank), BKR8E-11's swapped in place of BKR7E-11 plugs.
3/16/2013 - Initial tune of AE complete, enabled EGO closed loop and closed loop idle. Hot restarts still common - created VE Table 3 (table-switching) with 15% more fuel across map to run manually if needed during hot-restart. Replumbed power steering hose. Annoying interior rattle found to be rear-view mirror.
3/17/2013 - Violent high-load low-rpm bucking found to be launch control. Assumed to be involving grounding issue on account of cruise control module. Regrounded throttle body ground in effort to clean up TPS signal - still see spikes 100%/s so increased AE threshold to 110%. Small oil leak off back of block was loose cam sensor caps. (left loose to adjust timing and forgot to tighten back down).
3/24/2013 - Installed HardDog HardCore HardTop M2 and FM frame rail reinforcements. Fixed Clearwater rear deck woofers (wiring issue). Replaced COP boots and springs with BECK ARNLEY 175-1068
3/29/2013 - Had alignment done by Foster tire care as per Flyin' Miata recommendations:
Caster: 5.0 degrees
Camber: 1.0 degrees negative
Toe-in: 1/16", 0.15°
Camber: 1.5 degrees negative
Toe-in: 1/16", 0.15°
Camber on front was left at 1.5" due to passenger lower control arm wear - should replace and realign.
Plugged in neutral safety switch - need to wire up launch control. Moved COPS ground away from main grounding point and cleaned up sensor signals.
3/30/2013 - First Auto-X test of 2013. Need launch control wired, AE adjustment, TPS shielded wiring, interior plastic screws for top, spring for two piece downpipe
May 31, 2013 - 155602
Mobil 1 synthetic 5w30, k&n oil filter. Installed fire extinguisher.
Lookout for 205/50/15 15x7
Revised launch control use MAF blk/ltgrn wire. Blk/Ltgrn ground source clipped behind master cylinder. Leg from 2F (4F on DIYPNP) ran to neutral safety switch. Grounds when pushed.
