Thanks for the feedback and input. ive been thinking about seeing if i can setup sequential injection / spark but havnet had the time yet. Im still fighting with this issue where some times when i drive ( even at full load ) AFR varies -+1.5 points so i pull over, turn the car off then restart and drive under the same conditions and its within 0.2 for the rest of the trip. It seems to be it has to be something to do with the restarting process or something that happens when the wideband starts up but honestly ive ran out of ideas.
If it was grounding ( have tried multiple grounds / soldering / crimping 3m connectors ) surely restarting the engine woudlnt matter. the only thing i can think of is a failing ignition system perhaps that on some restarts is crappy and causes misses that i see as AFR change, just a wild guess i dont know if thats even a sensible thing to think.

For the money and stability of EV14's, the cost is easily paid back in the ease of tuning them. I'll say it over and over. They idled my supercharged 1.8l with 9lb flywheel better than stock. That's how stable they are.
