Switching from untimed ignition to seq/semi seq
*Reposting because I accidentally posted in general ECU and not MS, which I can't figure how to delete on an aside*
Hey guys,
I've gotten my 2000' with a fm voodoo 2 and MSPNP2 working pretty well using untimed injection, and now the time has come for me to finally get around to swapping to sequential/semi seq. As I understand it, only the na6s needed physical modification to support sequential injection, and as such my NB1 should be just a software change. When using the default settings for seq injection, it goes from idling pretty smoothly and revving with only a bit of delay to running like someone threw a bunch of gravel in the intake manifold, all over the place, very shaky and bad AFRs.
Can someone give me an idea as to what settings I should be running as a base for seq injection (preferably on a bp4w)? Attached are the default settings.
Car Specs: 2000 BP4W, FM Voodoo2, MSPNP2, deatschwerk 700cc

When I did this on my MSPNP2 I started with this link, very informative: http://megamiata.blogspot.com/2015/0...ion-and_8.html
DIY has some info here: https://www.diyautotune.com/support/...ial-injection/
If you want more information there are links to follow, but the image below is what you want.
Fixed seems to do the job and is presumably better than batch, can go to tables if you want to get more into it.

Also, there's more here on this forum, but it is more involved when you get into tables. Check this thread for some tables info.
