Thread: some questions about the realtime

hey, well im going to tune tomm afternoon, and i wanted to ask a few questions. first off, i noticed there are multiple timming and fuel maps, which ones does the ecu actually read?

also what is with the wacky fuel values? half the map is in the mid 190s and then suddenly they all drop the 20-30s....? im sure there is an explanation but im a little confused.

Hi Cory,

Just the primary, on the B13 and B14 SR Nissan didn't use that function. Notice on stock bins the primary and secondary are identical. Make a habit of copying the primary map over the secondar (in TunerProRT, click cntl+A, ctrl+C, then in the top left most cell of the secondary ctrl+V).

Your looking at where the O2 feedback is turned on. The most significant bit in each cell indicates that, and hence why the numbers look funny. See how on each map there's two tables but both with the same address? I.e. primary fuel - feedback, and primary fuel - no feedback? Open them both at the same time and compare. You'll see where the regions stop and start.

When you tune, you really only need to change the three right most columns for WOT tuning. Don't touch the rest of the fuel or timing maps.
