I have a Neo, and my car was wrecked in janaury, well we took out all the electronics so they wouldnt be borrowed or stolen.. I have notice my car just isnt runing like it did before... Is it possible the neo could have lost my tune? It was unplugged for almost 2 months. I unplugged it only beceause the shop that tuned my car said it would not loose my tune.

It doesn't lose the tune. Do you have the right map on?

Mike if your NEO is like the SAFCII, which I'm sure its a lil better A-it shouldnt loose its tune, B-it has 2 maps for two diffrent tunes so make sure its on the right one.

You can look at your "AIR MAP" under the "SETTINGS" icon and see if there are still any values entered in for the different RPM levels i.e. 500rpm +2, 1000rpm +2, 1500rpm +4. If those are still there than all your other settings should be.
What was repaired on your car, any engine components that could affect your A/F mixture???
Did you do the "Idle Air re-learn" from the FAQ section???
If they did indeed blank out on you and you dont have them written down in your APEXI manual then you will have to get it retuned.
Can you define "not running like it did before"???
And I dont think the AFC NEO's have 2 settings, I do believe its either on or off. Or at least as far as I know, I dont claim to know everything about it just what I have taught myself.

Well after thinking about stuff and getting a good tank of gas, I think it was just some bs gas.. Cause when i filled it out said 3.99 for 91 octane, then when it started to pour the gas it droped to 3.79, didnt think anything of it till i tried to race......... but this weekend my car sure did seems to run good...

I noticed my car was throwing codes some days and others not. If I get gas at certain stations the premium there will make me have either misfire or cat codes. It wasnt because of the trucks just filling the station either, took me a few months to verify it but my car just didnt like the gas there.
This only started to happen after my headers were installed, I was fine with just a Y-pipe.
