In everything I have read about SD tuning the E38, the VE low altd table is always RPM vs. MAP. Is there something I missed? Mine is RPM vs. TPS. I'm going to switch to EQ<>VE 4 and use it to modify the data directly. I took a first stab using Bluetorp's method, which is to create the VE table with EQ<>VE, then import it into the low altd table for manipulating. I ended up with a stumble in 4th gear with TPS > 50% around 2000RPM. I think it's because the TPS columns don't match the MAP columns that the table was created for?
Here is what my low altd table looks like. What am I missing here?
