Hi Guys,
It is time to whore myself on DYIEFI again.
I just released Spartan Lambda Controller 2, which replaces my Spartan Lambda Controller.
http://www.14point7.com/products/sparta ... ntroller-2
The webpage will be updated soon, right now it is mostly a carbon copy of my Spartan1 webpage.
Changes WRT Spartan 1:
-Spartan 2 uses the Bosch 4.9, Spartan 1 used the Bosch 4.2
-Spartan 2 uses all Automotive grade components, AEC-Q100 qualified
-Spartan 2 uses all high temperature components, -40C to 125C
-Spartan 2 has an extra wire that connects to a LED, the LED will show sensor temperature, slow blink = too cold, fast blink = too hot, solid = just right
Product features
-Lowest Priced wideband controller on the market, $75 without sensor, $125 with Bosch LSU 4.9 (even when compared to other widebands that use the cheaper bosch 4.2, Spartan2+4.9 @ $125 is still much lower priced than any of my competitor's wideband+LSU 4.2)
-Uses all Automotive grade components, no other wideband controller at any price uses all automotive grade components
- -40C to 125C operation, no other wideband controller at any price offers such a wide operating temperature range
- 0 to 5 volt linear output, 0V @ 10 AFR linear to 5v at 20AFR
- simulated narrowband output
- Sensor temperature display via LED
- 2 year warranty, twice as long of a warranty compared to other widebands on the market
- Water, dirt, and dust proof
New Wideband Controller from 14Point7, Spartan 2
Re: New Wideband Controller from 14Point7, Spartan 2
Any support gonna happen for richer mixtures, down to .5 lambda or lower?
Re: New Wideband Controller from 14Point7, Spartan 2
No idea what Alan's plans are, however super rich and super lean mixtures are of limited use anyway for the vast majority of applications, and making it configurable would mean adding comms to the loom which would add cost and complexity and isn't important to most people. So I guess for the Spartan at least, that's not on the cards. Other products, who knows :-)

Re: New Wideband Controller from 14Point7, Spartan 2
There are 2 problems with going richer than 10 AFR (0.68 Lambda). First issue is that the Bosch datasheet only specifics operation as rich as 0.68 lambda. The 2nd issue is that I have chosen to output 10-20 lambda on the linear output of my units, this is a pretty standard output which is compatible with a wide number of gauges/ECUs/dataloggers.
The first issue is not a big deal to me, the 2nd issue is the big problem.

Re: New Wideband Controller from 14Point7, Spartan 2
I have a question which I could probably find the answer to elsewhere, but would like to have documented here:
Is the thread on the 4.9 the same as the 4.2? IE, is it a simply matter of unscrewing the old and inserting the new if your'e upgrading units (say ripping out a crappy old LC-1).

Hey guys,
I am wondering if anyone has heard from Alan (of 14point7) recently. I ordered some goodies from him but I haven't been able to get a hold of him to get details on order status.
Cheers
