open loop question
i got uberdata installed a while back, FINALLY got it working right (my soldering job sukked :P), anyway i'm looking to play around with it, maybe do some fts & launch scripts or what not, and mess around with some of the settings...
my question has to do with the disable closed loop box. i know i want this disabled when i slap the snail on there, since i'll be looking for around 17:1 a/f at idle, 16:1 partial etc on down... whereas closed loop is gonna be constantly messing with my tables to try to get it down to 14.7:1. so i definitely want it on with the turbo, but what about n/a? i drove it around w/o CL one day when the engine was warmed up and not freezing outside, seemed to run really well, felt like a lil more power but the butt dyno has been known to have been miscalibrated before
are there any problems with leaving it in open loop all the time? will it hurt my engine on cold mornings or driving around partial throttle all day? i really dont care if it sucks more gas that way, i'm getting 30-something as is so i can't complain.

Re: open loop question
i run open loop full time. it's best if your vac maps are tuned or you'll might possibly be too rich...lean on an n/a car isn't too big a deal unless it's in the lower vac colums approaching 0 vac.
if you need someone to wideband/street/dyno tune, let me know. i'm in your area.

Re: open loop question
^^^like he said.
After seeing what kind of partial throttle/low boost A/F ratios I was getting in closed loop I would never run anything but open loop.

TurboEdit has that option?
