14point7 users opinion on Spartan2?
Looking to get a low cost, gaugeless WBO2 and am looking at the 14point7 Spartan2.. I know a few around here have them, how do you like it? I have an old AEM 30-2301 4.2 based unit for the wife's JRSC car, but need a new unit for the turbo car (which is getting the ME221) since that's where I stole it from.
So, thoughts anyone? For $125 with sensor it seems like a perfect fit assuming it performs long term...

The Spartan 2 is great. The calibration feature is really nice since it doesn't have a gauge. The one I have experience with doesn't have too many miles on it, but I've heard good things about longevity.

You tuned with Spartan2 or with AEM X?
I did enjoy this article (sadly lacking 14point7 products): https://www.fordmuscle.com/archives/...tout/index.php

Can the me221 take a digital can input?
I struggled to get a reliable signal from my aem analog output. The gauge would show pig rich 10 ish afr and ms3 will say I'm on target at 11.5 ish.
got a digital can module for ms3 and now all is in sync.

In case anyone cares - Latency testing (still without a Spartan though):

Here is Spartan2 review I wrote in 2016. I am still have Spartan2 on two my cars without any problems.

Whelp, finally finishing up the oil leak fixes and put the drivetrain back in, with the new Spartan2 sicne it arrived while the car was apart. I can't get it to read properly, it seems to be stuck just under 5vdc on the WBO2 wire. Red to switched 12v, black to the head where the ECU is grounded (per factor manuals), white heater ground to the chassis by the passenger shock tower, brown not connected, blue not connected, green connected to O2 input to ME221 (same as the AEM was). Any suggestions?
I bought two, so tomorrow I am going to plug in the other sensor and see if the results are the same....otherwise I'm not sure what to look it, it's pretty simplistic (which was the point).

perform "bench" test to make sure Spartan is working properly (with external 12VDC 5A power supply) :
+12V to red wire
-12V to black and white wires
measure voltage between green wire and -12V
first 5 second voltage suppose to be 1.333V
next 5 seconds - 3.333V
later - 4.98V
+12V to red wire
-12V to black and white wires
measure voltage between green wire and -12V
first 5 second voltage suppose to be 1.333V
next 5 seconds - 3.333V
later - 4.98V

After reconnecting to the ECU, now it's jumping from 1.64v for 4 seconds, then drops to zero, immediately jumps back to 1.64.. repeat.
