Working with a B13 SR20VE is really straightforward-
-You've only got got two knobs to play with, your fuel map and your timing map, so don't adjust anything else (in the ecu, do adjust your VVL switch points).
-Note that there are two fuel and two timing maps, but their both identical. Keep them this way. The ecu doesn't use the secondary set, but make a habit of copying the primary to the secondary. To do this open both, hit ctrl+a on the primary, click the top left cell on the secondary, then hit ctrl+v. Then hit the 'save' button.
-Note that for both the fuel and timing maps there are two 'maps' that both point to the same address (e.g. for the primary fuel map you've got
'0100 - Primary Fuel Map - No Feedback' &
'0100 - Primary Fuel Map - No Feedback'.
These aren't seperate maps, they both are editing the same table in the bin, its just a different way of looking at it. Think of it like wearing a different pair of glasses.
Why is this? Well, each value in the table is an eight bit number. The most significant bit is used to designate a kind of region. In the fuel map this is the O2 feedback region, in the timing map this is the knock feedback region (i.e. in both cases where that sensor is actually used).
Notice that for the VE program (like all my programs) there is no knock feedback region. So in your case you never need to look at the 'knock' view of your timing map.
For the fuel you never need to work with the 'Feedback' view either when tuning WOT (i.e. on a dyno). The reason for this is under WOT you'll be operating on the far right column, and note its all in the non-feedback region.
-Do spend a little time before the dyno session (and not right before, you can do this tonight in about 5 minutes) verifying where you are operating on the fuel/timing maps. Note that I've got the TP (this is load, not TPS, it stands for 'Theoretical Pulsewidth' and is the pulsewidth calculated for the current MAF voltage and RPM needed for 14:1 AFR) and RPM scales of both fuel and timing maps the same, so if you trace one you know where you are on both. Simply do a WOT pull on the street and watch in Nissan DataScans map trace mode. See the 'map tracing is cool' sticky in my section of the sr20forum if you don't know how to do this.
-That being said I know your going to be in the 60-68 columns. Note I made them all the same, keep it that way.
-Do have some consult app running so you can check your operating conditions. Make sure your fully warmed up. Not got the consult side working yet? Post here or call me and I'll walk you through it. Its easy.
-To increase a value hightlight the cells you want to increase and hit ctrl+'+' and to decrease ctrl+'-'. The timing map is really straightforward, the values you see are is your timing (assuming your base timing is set to 15 degrees). The fuel map is also pretty straightforward- the values are really a multiplication factor of the base injection, so big numbers = richer and small numbers = leaner.
-Remember, you've really got three copies of the bin- whats saved on your harddrive, whats loaded into the laptops memory (ie TunerProRT), and whats on the ecu. You've got to keep these three in sync. Just press the 'up' arrow to upload the whole bin to the ecu (no need to turn the car off), and the 'disk' button to save your changes to the harddrive. You can also put TunerProRT in 'emulate' mode rather than uploading whole changes (push the 'chip' button), but I usually periodically upload the whole bin just so I know everybody is on the same page. It only takes 30 seconds to stop and make sure everything is syncronized; you've got plenty of time to do this between runs.
-Do make notes about what you've changed. Make a copy of your original bin- you can use the compare function in TunerProRT to flip back and forth and see what you've changed.
Thats it. If the above doesn't make sense just print it off and show it to your tuner.
Have fun!
