Alrighty then. The story goes like this.
I get my LC1 plug it into a 9v adapter, setup the correct megatune required AFR settings which as everyone knows are 0v=10afr & 5v = 20afr. So I go ahead and install it in the car. That same day and subsequent days later I start to experience a recurring problem where it would need a new free air calibration after every shutdown. I thought, maybe its a firmware issue, let me go upgrade the firmware. I take it back in the house, upgrade the firmware. At that point, pay attention after the firmware upgrade I looked at the output scale settings and saw they did not change in the program. I took it out to the car, plugged it in and tried tuning. The problem persisted, constant free air calibrations. I came on the forum if you guys remember and asked wtf is going and even emailed innovate about it. The solution was to ground everything to one point and terminate the in plug while its in the car. Miraculously the problems went away and I started tuning.
I spent 2 weeks tuning the car with the laptop because I didnt have time to put the gauge in.
Fast forward to yesterday.
I put the gauge into the car and I instantly get a discrepancy in the reading. I think, OH **** this gauge is only designed to work with the factory voltage range but I hope its not that stupid.
Fast forward to today.
I come on the forum to make this thread, what the **** this gauge only supports the factory voltage how gay is that blah blah blah I cant emulate at the same time because I need to have one output for gauge and one output for the MS.
Fast forward to later in today.
I start to get pissed off at the fact that my readings are fucked up and I start to wonder, I WONDER WHICH OF THESE IS MORE CORRECT the gauge or the MS.
I start to also get pissed because id need to pull the LC1 out of the car to bring it into the house and then redo the god damn free air calibration and **** up my hands again reaching for the sensor.
IT DAWNED UPON ME ONLY NOW!!!!! This whole time with the megasquirt, and now the LC1, my laptops docking station has a serial port. I didnt even need the converter plug technically, and the first time I programmed it I didnt need to bring it into the house.
Beside the point.
I just ran outside plugged the computer into the LC1 and open LM programmer.
WHAT DO I SEE?
The factory DEFAULT settings in ever single window. The second output was setup to output 7.35 - 22.99. This whole time, for the past 2.5 weeks I have been tuning with the wrong god damn output on the lc1
Yesterdays event with an 11:1 idle on the gauge which was 13:1 on the computer was dead on accurate, except the gauge was right and I am a ******* idiot.
GAME SET MATCH, LC1
Guilty on counts 1,3,5 of being an idiot.
