Today I put in my DSM 450s, and set the fuel pressure the way it should be... Idle sucks balls, sound like I have a huge loping cam, CEL comes on with a "lean" O2 code at 'high' vacuum (20-30"). So I went into TE and changed the "-17" to "-30" fuel map, I added 25%, and it seems to run ok now, and idles fine, no code...
I follow all of the directions on how to setup a basemap by importing the maps, then adjust everything just like the "how to setup a basemap", setup for everything I'm using at the moment, and its always EXTREMELY lean until I adjust it. Has anyone else came across this??
I am running a PM6 ECU, in a '91 Si with a D16Y7. It is not turbo at the moment, I'm trying to get used to doing this stuff before I boost. 450cc DSMs, 38psi fuel pressure at idle, no other mods...
