what kind of driving conditions should i log for slopes and breakpoint? should i just do an idle to 2k like the maf and isc settings or do some driving around?

Hey, I'm interested in the answer to this queston too. I have another question for you. Is your car an a/t or a stick? Is your dyno test and ET with or without the chip being tuned? I would expect better numbers for the set up you have... or at least I'm hoping for slightly better numbers when I do similar mods.

stick. stock tune for the dyno and ET. i only have a handful of clean passes on the bottle so with some more seat time and a good launch im sure i could knock off a few more tenths. im also upping the shot a bit so im hoping to be somewhere in the 11's.

I'd get all driving conditions and try to filter out the decels/coasts where the injectors might be a little screwy. The transient enrichment also can skew things a bit so keep that in mind.

i do mine driving around under real life driving conditions. I ride the car alot easier than my friends drive changing load and shift points in the A/T.

I find the car runs better when i log and drive the way i usually would.

i've never had success free revving w/o load on the engine.

When dialing in your injectors you usually wanna stay in Closed Loop

That is gonna require a very light load :Word:
or
You will slip into Open Loop

You are gonna want to go easy ... very easy ... on the go pedal

I used to climb a slight hill in 4th on the freeway so I could get some
high pulse widths

I'd start the hill at about 50mph and usually between 65 & 70 I'd
slip into Open Loop
