Ok guys, I installed my Zeitronix ZT2 w/ display today, everything is wired correctly and I have it wired for simulated narrowband. So the check engine light comes on and it runs fine right, well thats normal. So, I go and change the StockLS.bin and check it to disable the o2 heater and burn it, put it in my ECU. Reset my ecu and start it up, no check engine light, but the car runs extremely rough, shakes alot, and looking at my AFR at idle it's at between 10-10.5.

The only thing other then wideband that I have done to my car is a Walbro 255 fuel pump. Anyway, after messing with different things I gave up and put back the StockLS.bin and deal with the check engine light. My AFR at idle like this is about 13... when I was messing with the uberdata config I upped the fuel pressure to 55 because I read that it ups the fuel pressure by about 10. Doing this made it run a little better, it didnt shake as much and idled between 11-12. I checked closed loop and o2 heater and still it ran like complete crap.

I don't know what else to do, could anyone PLEASE give me some advice? Am I doing anything wrong? Is there something I should know that I don't? PLEASE HELP!
