Well the beast is running with the Spartan Lambda Wide band hooked up, but not really well, it seems to only rev to about 2000 rpm and feels rough when accelerating. I think the timing must be off or a setting is restricting the rev. I have checked the rev limiter settings 5500 low ,6500 high ...

Can anyone tell me exactly how to wire the spartan lambda wide band o2 sensor by 14.7 to the ms relay board, it has five wires and I want to get it right the first time?
Thanks again.

Ken,
does this sensor just plug right in to the Ms relay board? nothing else required? if so the i am settled on it. where did you mount your o2 sensor?
thanks again, i will post up the tune when i get it installed.

oh i am running 10 % ethanol gasoline, compression ratio is 10:1.

ken,
i will make these changes. i guess i just misinterpreted the data for those settings, it seems like it is running lean so im not going to fry the motor, i am going to purchase the sensor you recommend and see how she runs then, the idle is high around 1200 rpm, is that normal?

Ken,
I cant believe I overlooked something so obvious, I just went out to the garage and it fired up! I guess I just needed a fresh eye to peer into my frustration! Thanks and let me know if you see other major mistakes! It feels so good to hear this engine jump to life, finally!! :yeah!: :D
I can ...

Ken,
Here are the files. Let me know if something looks off. I will try to get it fixed ASAP.
Thanks,John

I do have 12 volts at the injectors, checking with a digital voltmeter, even while cranking the voltage drops down to around 9.9 v at the lowest point before I give it up and let the battery rest.
