Default LC1 issues and Gauge issues

So ive had a LC1 in my truck for about 2 years i guess.. been workin fine, couple weeks ago it started just jumping around on the numbers.
So i unplugged it and did a free air calibration. Didnt help.

I bought the DB series gauge with a new LC1 and hooked it up the other night and i cant get it ro read right for crap.. Ive tried to program it like the manual says and its maxed out at 20afr. and 4.1? Volts..
So i just quit messin with it before it got too pissed off.

I also got the Cyberdyne Fuel Pressure gauge.. Its wayyy too bright at night time even with it dimmed. Not to mention its reading 7-8psi low.. Checked it with a manual gauge.


And what really got me is the other night i was goin to flash a tune back on my truck. (pulled 4* timing to spray at the track) so i was flashing my original tune back and went to start it up. It fired off but struggled and died. I waited a minute and tried it again, Same thing. Fired it up again and got on the throttle, it revved to 2000 and spit and sputtered and died out.

Got fustrated so i tried to flash the tune i just had on there. Same thing. I kept tryin different tunes and finally one of them worked. Now i cant get neither of my widebands to work to check my AFR..

Im goin to email Innovate and cyberdyne to try to get some of this straightened out..


Anyway, rant over.

oh and gas went from $3.60 to $5.17 today... Dunno whats up with that .

Jonathon the LC-1 are notorious for ground offsets. You have it grounded straight to the battery and all that crap, I dont know why it would move and change tho.

Ive had tunes that didnt flash right. I then repeated the same tune and the truck would work fine.

Dont fill up with gas today.
