np.
getting a wideband and installing it is very cool.
people need pics for parts/install stuff.
good luck on the tuning.

ok guys, i have made some changes mostly to vaccum, in boost i started at 118% correction, now im down to 115% and getting 11.8-12.4:1 pretty steady in boost WOT, at idle from 21 in vaccum to 17 in vaccum i have pulled about 34 % and im still bouncing from 12-13:1 at idle, and from 15 in vaccum to 3 in vaccum i have pulled 22% and im bouncing at part throttle cruising from 15.5-18:1 .....my question is, in vaccum when i re enable closed loop ( all open loop right now) how much will the 02 trim be able to compensate? do i still need to get it closer to 14-15:1 in open loop? oh and my vaccum never drops below 20 in unless im deceling but during decel it drops to about 24 in vaccum and just goes mad lean, should i worry about that?

If you're bouncing between 15 and 18 at cruise, you certainly need some more work on that part of the map. That's a pretty big ------ to be jumping around in.

Get things as close to stoich as possible; if you're too far off, the ecu is going to be throwing O2 codes from time to time.

During decel, the ecu is going to cut off your injectors. This is normal. Don't worry about it. My wideband reads "lean" and "air" during engine-braking in 5th gear.

thanx for the input, i have only worked on it for about 2 hours and this is my first time tuning i for sure need to put some more time into it, i havent been able to datalog yet because i need the cable ( buying from xenocron tomarrow ) but i have a feeling it will be easier when i can datalog.....

Datalogging makes a world of difference.
