TR6 Member Region: Southwest Car #: 500 Year : 2002 Posts: 179 Status: Offline posted         Where is the preferred location for mounting the sensor unit: the transmission tunnel or in the trunk? Can you think of any reason NOT to mount it in the trunk? It seems like it would be more secure and safe in the trunk.

This puts the sensor almost right in the center of the x and y axis of the car, giving more accurate g-force readings than in the trunk. I have mine mounted all the way at the rear of the tunnel, therefore out of the way of my arm/elbow. -------------------- Lee Tilton 1993 Meowta #04 Brimtek Motorsports/ Team Four Racing Team Four Racing George Munson Member Region: 83 Car #: 127 Year : 90 Posts: 284 Status: Offline posted         TR6, Lee is correct on the location for the reasons he sited. I mounted mine in the same basic location but installed small 1/4" to 3/8" underneath for cooling puposes. Its been there for 2 years.

Even after a head on hit the SU was fine and didn't move. -------------------- Paul McLester Jay Lutz Member Region: Indy Car #: 33 Year : 1994 Posts: 422 Status: Offline posted         Trans tunnel on a mounting bracket. I used 10-24 rubber isolated "Wellnuts" to try to filter out some of the accelerometer high frequency vibration that is not performance related. I think a velcro mount would do about the same thing. Wellnuts look like rubber tophats with a brass threaded insert in the center. You place them in a drilled hole and as you tighten the thread the rubber expands behind the drilled hole preventing thereby trapping it. In my production days I held front airdams and fender flares on the same way. Very secure but things can move around a little if needed. You can purchase wellnuts at Home Depot and Lowes but there are cheaper places. -------------------- "In our sport if you go out of bounds you're most likely not coming back" Michael Waltrip TR6 Member Region: Southwest Car #: 500 Year : 2002 Posts: 179 Status: Offline posted         Yes, this is for a Traqmate. I left that out by mistake. Thanks for the tips! -------------------- Greg H. 2002 red Miata #500 Denton, Texas Printer-friendly view of this topic | Subscribe To Topic Hop To: Select a Forum:   Category: SpecMiata.com -------------------- Spec Miata Spec Miata Garage Spec Miata Rules & Competition Spec Miata Competition Tires Spec Miata Safety Spec Miata Setup Guide Spec Miata Data Acquisition NASA PTE/E3 Spec Miata to FProd SMulators Spec Miata Frequently Asked Questions Showroom Spec Miata Pro Miata Spec Miata Enduro Spec Miata Virtual Swap Meet SMTV Back Fire Announcements   Category: Spec Miata Archives -------------------- Spec Miata 2001-2009 Garage 2002-2009   Category: Sports Car Club of America -------------------- SCCA North-East SCCA South-East SCCA Great Lakes SCCA Central SCCA Mid-West SCCA South-West SCCA Rocky Mountain SCCA North Pacific SCCA San Francisco Region SCCA South Pacific   Category: National Auto Sport Association -------------------- NASA Discussion NASA Northeast NASA Southeast NASA Central NASA Midwest NASA Northwest NASA Southwest   Category: Mid Western Council -------------------- MWC Discussion
