Re: fuel injectors not firing

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 ...

Re: fuel injectors not firing

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.

Re: fuel injectors not firing

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?

Re: fuel injectors not firing

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.
