The "correct" place to tap the MAP sensor, and your IAT install.....

So set the mainscale for proper trims and go from there.

(and check the TPS input, you might have a "Rustang" in there......)

so what are proper trims? low 100 or lower along with 02 trim. what about mid high trims?

also since my car is covering my plugs in fuel shouldnt i want to pull fuel instead of add it? i guess i dont understand that theroy, or what trims are telling me.

[Rustang Cobra]

you should really be goin for 100 for each trim, but bob likes 81 for each trim

i unplugged my Narrow band o2's today. so far, everything is running great, no CEL's... yet

from a start, it is actually easier to start moving, but i had some problems before.

I have also not had and idle problems or cruising problems.. yet

one question though. i got the tune good at idle, even though i still idle high, but under any load i begin to run very rich.. is this normal? i still have lots of bugs to work out, but it seems like this is the better route to go, plus when i upgrade turbos, i wont have to worry about replacing the narrowband o2's although i will still replace the wideband sensor for piece of mind!

well my question is what does the high numbers mean? and what do low numbers mean?

cuz i have done what bob said and added a bunch of fuel with mainscale and it still hasnt changed my low trim. my high trim and mid trims have changed but not low trim.

my trims are Low-140, Mid-124, High-88, o2-100(at idle) cycels between 80-100(while crusing) what should i do know. i have my main sale set at -35% and according to formula its supposed to be around -41.5%. now at idle the car runs very rich narrow bands are at like .80-.84, and hold there. while crusing the car runs better than ever. what do you think?

[TurboBob]

I would reset the ECU, and then watch to see if the idle trim learns. If not, lean the low tune at idle for proper mixture. Once you get in the ballpark the O2 sensors should start toggling again and the trim should learn. If not, fine, just tune it to where it runs well...... (with large injectors, you may be below an airflow limit to allow idle learning.....)

It sounds like you are making progress.

Bob

oh, and .80 at idle is not very rich. Narrowband sensors SUCK for telling how rich or lean you may be. On my car, the o2 sensor toggles from .80 to .20 or so, but the wideband DOES NOT MOVE........ from 14.7 or so.

So you are probably idleing at 14.0 or so, which is fine. I bet it idles pretty well......
