SD question with 2BAR hptuner
SD question with 2BAR hptuner If using 2BAR with hptuners, my understanding it is for SD only. I assume this means you can no longer use the MAF. What about closed loop using the o2s to keep steady as possible 14.62 stoich?
You can still use closed loop as normal with an SD tune. Oddly enough, you could also still use the MAF if you wanted to, but most boosted applications max it pretty quickly.
That is correct. I've done many 2 bar tunes on cars that needed to pass an emissions test, so we need to keep the MAF enabled. Contrary to popular belief, it does work.
That's when I assume the VE tables would come into play after the MAF is maxed out. I was told with Hptuners, you can no longer use the MAF.
I am waiting for an definite answer for the hptuner board.
