      The valve is factory. However I'm using MS to control it.

        Thanks for this, been having issues starting my turd for weeks. I used all of your cranking and starting settings, took 50 off of the iac values and it starts and runs with ease each time.

          Aj I downloaded and viewed your tune that I’ve tried to look at before and I noticed that even though you were running fuel only there is a spark table that has all 8s across the rpms. Well I started plugging in your timing numbers and instantly started seeing and feeling a better running ( or running period). So thanks for that. Now to my question you were running 80 lb injectors and I am running 42lb injectors can I just cut your fuel map by 1/3 or so? Or do I adjust by afr?

            I believe the 8s were there by default but I never used them since I wasn't running timing on MS yet. 8 degrees is pretty safe but not a lot of power and you should easily get more than that after you get fuel figured out. You'll need to play around with your own fuel map using afr. Start with the auto tune in MS and then fine tune it manually after that.

              Aj to clarify it’s 8s in the rpm ranges not timing degrees but it runs smoothly so far
