Default Late night Noggy testing (BWW)

I decided it was time to do another performance check-up now that it's warming up a bit.

Note: 3/8 tank of gas (93 octane Mobil), 50F, 24 PSI spike (touch too much IMO after seeing the logs) tapering to 22ish near redline

Here are my Lemmi settings (same as the previous 5-6 months). This combination has eliminated all misfire codes/CEL and resulted in solid drivability:

Notice the spike in MAF, going to turn boost down a touch (to where it was before I touched it, dumbass):

Not spectacular, will start playing around again to get things in check:

My guess is it's too rich. It'd sure be nice to have the wideband on right now so I could know for sure. Oh well, going to pull a bit of primary:

~20 degrees over ambient at the start and a delta of ~25 degrees, which is pretty flippin' sweet considering I did 3 runs (these logs are all of the 2nd pull BTW, other 2 are very similar) within a minute or so:

Increase in ambient temp has reduced airflow, resulting in lower duty cycle...but still over 100%:

I'm ashamed to say it, but I haven't been driving my car much lately. Today was the first time I really drove it for pure enjoyment in a couple weeks. It's such a great car, always capable of reminding me why I love her so much.

Looks solid man! ) Great times for this weather. Document the air pressure, humidity, and temp!

It's pretty simple how I have it setup now &lt;shrug&gt;. What do you recommend?

Default well like i mentioned i like to use the adjustable FPR, to each his own and clearly you have your...

setup nailed down very well. i like to only have to touch primary and accel/ deccel, with maybe a idle torque offset bump or two. this al goes hand in hand with how well your injectors and MAF are matched also as i know you know.

Default So you're saying the "too many tweaks" are idle speed, warm-up enrich, and start-up enrich? Hmm, ok.

I don't see how an adjustable FPR will help eliminate the need for those tweaks. If anything, it would eliminate/reduce the need for primary fuel tweaks AFAIK...which you say you still use.

Maybe you don't need those tweaks because you have better injectors (Motrons), but these tweaks have definitely proven to improve idle on other injector setups.

I would hardly call this too many tweaks, but like you said... "to each his own"

i dont like to have to even touch startup and warmup, idle speed for misfires is a bandaid IMHO

Default Pretty permanent bandaid that even some tuners use......

you're definitely entitled to your opinion

Default i would just rather get the injectors spitting the right amount at idle, that goes hand in hand....

with getting the right injectors in the first place.... i.e not greentops.

how are your bluetops at idle without tweaks? pretty noticable sputter or more of a on and of every 15 seconds type hicup?
