OK, so I'm super excited to have this finally installed. Got it in the mail last night and installed it about 10pm Today I familiarized myself with it and understand the interface a bit more. Interpreting the data is a whole other issue that will take time to tackle.
I was hoping to capture a little stumble that I have when the engine is relatively "cold." That being a relative term because it is summertime in Hawaii and it ain't ever really cold as the mainland knows it.
Anyway, after a cold start and a pull down the driveway, I normally idle along to the corner. When I make my turn, I get a little stumble/ chug when I apply throttle to get around the corner. Normally the stumble goes away in about 10 minutes of use or clears up when I hit 10mph or so. I was thinking that maybe the 60lb inj were a little touchy at low speeds, but it seems to clear up once the engine is nice and warm. Once warm, when I pull away from corners or do low speed maneuvers in a parking lot, everything is fine.
In this log I don't know what I'm looking for- and if we even can "see" the issue at such low speeds.
So for this file, I come down the driveway, idle to the corner (about 100 yds), turn the corner (little stumble), idle on to the corner another 100yds (wait at stoplight), stumble around the corner and drive 300yds to the next corner. I wait at another stoplight (city life I tell ya...) and I recall a little stumble there too as I made my final corner at the light (just drove in a big square). End run. The file is long, but I spent forever just waiting at stoplights.
Any insight to share or techniques to better capture this issue?
I tomorrow I'll tap the MAP so I can see boost values. I'll be on the stock 2 bar because I'm low boost anyway on 92 octane trying to run around 14-15psi. If I can score a 3 bar locally tomorrow then I'll do that of course. From there I'll get some cruise logs and some roll into WOT logs too.
Thanks!
