Gauging interest...pun intended, Semi-custom wired Wide Band O2 meter, AFR Options

[Mark Henry]

I'm making up several 14point7 SLC free 2, WB O2 meters for customers and myself and just wondering if this would be of interest to the brotherhood.

Problem with most O2 meters is the wire harness, most of the time they are just a bit short for a clean rear/mid engine install. The wires are often cheaper quality loose wire covered with the Chinese finger puzzle like plastic sheathing.
I'm using a high quality sheath, twisted, 6 wire with shrink wrap tubing on the ends, for the main harness.

How much? Is that a 14point7 SLC board?

Yes it's a 14point7 (.com) I thought I said this but I guess I didn't (IMG:style_emoticons/default/smile.gif)

You can buy this kit directly from 14point7 for $95, but you have to provide the wire, heat shrink, soldering, wire crimping, time, etc. No warranty
I want to keep it cheap than most others but one problem is the cable I'm using, it's more than twice the cost of a cheaper wire cable. That adds up to $10 extra bucks on the main cable. I looked at other cables, you gets what you pay for.

So ballpark $150. plus $15 std. post shipping = $165. I'll stick that as a for sure on the first 10 meters.
I will have to build 10 at a time to make it worth my while, but what I don't sell I'll put in stock.
I have 4 more here to build the cables for, now that I have my process mostly sorted, I'll time myself to see if I can do better with the 4 at once.

Other options, I could make a 2nd set of cables, one set for permanent install in your 914, the 2nd set so you remove the meter and lambda to use it temporary on a buddies car. Tentatively $50 extra, might bump up postage. BTW the cable is where the labour is and I'd have to buy a 2nd set of lambda and molex connectors.
Another idea is rentals, maybe complete Weber tuning kit, jet reamers, jets...maybe even a two meter kit for tuning a 6. (IMG:style_emoticons/default/idea.gif)
In case you're wondering you can't run two lambda's off of one meter. The lambda must always be powered when the car is running, one of the quick ways to kill your lambda is installed with no power.

I won't be ready to do these for a few weeks, my connector pin crimp set works perfect on the larger LSU pins, but not on the wire jacket strain relief crimp on the smaller molex pins. I have a better crimpper coming from Japan, ETA may 5th.

I also want to test them, I have meter and a brand new 2056 on the engine test stand right now.
Plus I want to do an full install on a 914 I think I need 12' of cable but some may not like how I'm doing this in my teen. I'll post pics and I need opinions on the installation.

Warranty, well it's electronic if you don't follow instructions you can fuch it up, but I will fully test every meter, provide clear instructions, I stand behind my cables and work with anyone that has a mishap. I will sell components separately and do repairs. I can provide weld in SS bungs, but I need a supplier for the caps (left), most carb guys can remove the meter after tuning and this would be a bonus if I was to do rentals.

These are pretty stout units, but if you wire it backwards, remove/install the connectors when the ignition is on, don't use a proper grommet, cut and short out the harness or run the car with the lambda unpowered... I'm not going to cover those kinds of mishaps.

Awesome! I've been really impressed with their other products-fantastic board reliability and the heater circuits seem to work quite well.

Your price seems really reasonable given the amount of cost and work that goes into making a really nice harness. Much nicer than the commercial-grade wiring 14point7 uses in their prebuilt stuff. Looks like the best of both worlds! (IMG:style_emoticons/default/first.gif)

I'm not in the market right now or I'd definitely by a customer.

Edit: Thanks for the really detailed response BTW. (IMG:style_emoticons/default/smile.gif)
