So ever since the 3.0 update when tuning my buddies truck with his AEM signal is erratic and all over the place like its reading way too fast compared to the gauge. Read about using a 10uf capacitor to fix this problem but do I wire it inline on the input to my hptuner pro or tie it in the input wire and ground the other side of the capacitor? Or is there an option for changing the response rate in hptuners. I've googled around since it started but never found a true answer. Read about people using it through serial that recently became available with some widebands, but nothing on wiring it up through the serial wire. Just like to get his to read correctly since its a boosted vehicle. My LC-1 reads just fine. Nice and smooth.
Edit I also have the ground from the hptuners to the same ground as the aem
