SD2 tuning
good2win22:
Drove the car to the UTI block party up north of Dallas yesterday. Went up and back and a trip over to Kellers drive in. A little over 300 miles total. A few observations:
Letting the presets in the chip handle the cruise fuel makes for a really steady wideband and narrow band reading. However, a/f correction still wants to pull fuel and the black on the end of the exhaust confirm the richness. Not exactly certian how to address this for cruise unless I go into the tables. Don't think I'm ready for that just yet.
TexasT:
Back the fuel pressure down a bit maybe? Just have to remember to crank it back up when you need it.
Scoobum:
Jason, I'm no help with this...but I'm curious what the AF reading is at cruise.
nocooler:
Think of it like an excel spread sheet
RPM on one axis and vacuum/pressure on the other. The cells are fueling.
The AFR and NB is going to be consistent as you are sitting in one or 2 cells for cruise. As the rpm and pressure is are staying steady.

Keep posting Jason I'm really leaning this way.
