Stayed in tonight...bored...here are some logs...

Swank4 · 09-03-2005, 01:09 AM

Had the VAG cable and laptop with me in the car today and so I did some runs on the way home from work. Air temp was 60F and elevation was about 500 feet. Running 91 craptane and full street trim.

Some timing offset pulled via Lemmi. FATS averaged 5.55 over two runs. Not sure why so slow...

O2 voltages might be a bit high (?). This likely due to the extra fuel added via Lemmiwinks...

Boost looks normal...

Here is a former post with some neat graphs too...
I am just wondering what kind of gains you can get with lemmi and stg 2 vs. a stg 2 chip like APR (mine) Thanks -

and run some logs with FATS to see what changes. Wish she were faster!

1. minus 3% of timing offset
2. plus 7.42% primary fuel
3. plus 141% secondary fuel

See my pic poster for before and after dyno runs. Credit goes to AudiS4guy for spending hours upon hours with his car (AMS A-box) on the dyno while playing with Lemmi to get more power. These values worked best for him and we got together to see if it worked best for me (M-box). We have very similar power and setup (Stage 2+).

He's been off the forum and email for the summer but talk to him for further info. Note, I'm not convinced that these values will yield the best power for everyone. Conditions were 88F, sea level, 91 craptane...so IATs were high. In cooler weather or different octane I think this setup might not be optimal. I'm going to do some testing this weekend.

I'll try playing with the fuel a bit... and run some logs with FATS to see what changes.

TIA. __________________ 2001 S4 avant / RS6-K04 turbos / ASP custom tuning / Fast Intentions 3" downpipes / AWE Twin2 exhaust / AWE ICs / Aquamist HFS-5 / SPEC 3+ clutch / Stasis Motorsports (Ohlins) 700F/800R / Stasis Alcon 355 BBK, 298 rears / H-sport rear sway / Stasis 4:1 rear diff / Zeitronix wideband O2 / FATS = 3.35 on 91 octane / Land & Sea dyno = 429 whp.
