ign off .1
ign on 20.1 down 4.3
fuel pump 20. down 4.5
water pump 30 down 4.5
cooling fans 1800 down 10.5
these are spike down to run mV AC
will do some more test latter tonight.
Sweet, good luck Man and let us know what you find!yes.
was packing up my garage and took a quick beak to do them tests
will do another one with the eng running tonight. And if it has a issue will disable the alt and see what happens

My tune,....is that the o2 goes to Sleep/freezes up. this is the problem i'm fighting and can't "tune until i give up on the LM2 or fix it.I use something like this:
12V Car Battery Monitor via bluetooth APP Voltage Meter Tester w/ auto Alarm
If your battery and charging system are not up to the task then fix that as that will affect your tune.
Great job on the detailed checkout, doesn't look like power is your issue. Unless a wire is rubbing or you have an O2 sensor that's wonky it looks like you have a bad gauge setup.still no answers
started and let idle manually activated each one, on and off no affect.
held eng at 6000 rpm and turn on and off, no affect.
The cooling fan was the only one that would spike when turning on. some time it would flash around 1800 mV and some time it would show an open for that split second, AC mV never got above 30.5 mV held around at anytime during test from idle to 6000 rpm.
These test were all done in park(no G force) will have to sneak it out on the road to test that again.............but i haven't found or fix anything so i bet it will still freeze up.
How ever it did not freeze up at anytime during this test.................
Tomorrow will be my last test. then if i'm luck and all goes well with the move on the 20th i may be able to sneak off to the race on the 22th. finger crossed.
I never disabled the alt because there was just not any problems between idle and 6000 rpm.
and as i said the o2 did NOT freeze up on me.

cuda will set all winter and start right up the first time i try in the spring.
I have the factory gauge in the car. Haven't put a volt meter on it to know.Do you have an alternator on the car and what voltage are you seeing it charge the battery at? Contrary to popular belief you can tune an engine without O2's
I have replace several several o2 sensor just to make sure, and have killed a few as well(leaded race fuel)Great job on the detailed checkout, doesn't look like power is your issue. Unless a wire is rubbing or you have an O2 sensor that's wonky it looks like you have a bad gauge setup.

Yes i realize that and have done a lot of tuning with a timing light, 60 foot and mile per hour.
However, you can't watch it go lean or rich as it pull thru the rpm range with just plug readings.
Playing with air bleed is were an o2 can shine.........If it works.......

Do you have an alternator on the car?High speed air bleeds....maybe.......... need o2 to record a full run with out freezing up to know.
yes electric pump, next to the gas tank.
