| Just looking at those tables and I can see a few "issues" if you may. First off in the VE2 adder I see a jump of 12% between 3200 and 3600. Combine those tables and graph the results. You'll see what I'm talking about. Not to say that you shouldn't give your engine what it wants but I would recommend keeping the tables pretty smooth without many divots. Grumpy will tell you to give the engine what it wants but if you're using 160 baud ALDL then trust me on this one, keep it smooth. Dips in the tables will mess with your AE and transitions. The only time for dips is to force the engine to do something abnormal. Basic physics says that if you have more pressure then the volume of air is greater hence Vol eff of an engine should always be increased with pressure, never the other way around.
How are you going about tuning the vol eff tables? BLM, INT, and/or O2?
I don't know because I haven't played with it much but I think the 61 mask is aggressive with the idle SA adjustments. I really haven't played with it much but I still get a stumble almost stall every once in a blue moon. This was messing with me and I haven't checked the o2 sensor. I haven't done much tuning as of late, I usually do a couple changes, pick what I like best and drive around with it for a few weeks taking mental notes.
If it helps, the VE "curve" should look like your torque curve. This is just a suggestion and might save you some time; slap on a carb and program in a typical ignition curve, chassis dyno it making certain the AFR is pretty good (not too rich and not too lean), then look at your torque curve results. This will get you a peak for your vol eff curves. I was going to do this but had access to some very powerful simulation software. |
