Little bit of a stupid question here, but I'm full of those, anyways the Y value on the WGDC cycle what does that stand for, I know the X is kpa, right? And then the numbers the graph uses itself, I see some spots at 3 and some at 58 and then 15, what exactly does it mean? That's the only thing I don't fully comprehend. Fuel and timing are easy its just load and rpm, and the fuel table is in afr while timing is the degrees. Same thing with the P-factor, what does the x row mean? Same with the actual numbers in it.
What exactly is wrong with mhd+ tables anyways, if it's a simplified version of everything, what's wrong with that? Cause I really want the map switching.
Add “Boost Setpoint” and “MAF Req. (WGDC)” to your logging. These are the axis for the “WGDC (base)” table that we will be adjusting. If needed remove other unused monitors from your logs to make room. Once these monitors are added, collect a log where throttle closures can be seen. The X axis for the table is “MAF Req. (WGDC)” and the y axis is “Boost Setpoint”.
Now, look in your logs and find where Actual Load surpasses Load Requested. Once you find the problem area, look at the corresponding values for the X and Y axis on the “WGDC (Base)” table and that is where you will be making your changes. Find the cell that matches and highlight adjacent cells as well (the DME will "blend" several cells to get final values). You are going to want to lower the values in the problem area to correct throttle areas or raise them to correct under-boost/under-load. Make small incremental changes to the base table then re-flash and re-log.
GENERAL = Increase WGDC Base > More Boost
Over shooting boost > reduce wgdc table based on location of MAP Requested WGDC (Airflow) and Boost setpoint factor intersect.
Under boost > add wgdc to the intersection point (add in segments of 5-10%)
Wgdc adder > if you do not hit targets add to the last column (333) on most tunes we are over the wgdc airflow amount of 333 so just focus on the last column OR Increase the WGDC adder/ceiling table beyond 333 to increase boost.
Note: Starting from different gears and RPM will change the sweep of the curves and will take some fine tuning to achieve a smooth boost curve for all gears and starting points.
