engine fuel/ignition map for new build
I am doing a new build
Upgrades include new liners, forged pistons, forged rods, stage 2 cams, upgraded valve springs/retainers/valves (all from Supertech), custom headers, larger capacity injectors, TVS, custom intake, LS1 throttle body, return fuel line, aluminum/steel flywheel, all running on MEFI4B controller.
Not looking for ultimate power, just a nice reliable street machine
I have access to an engine dyno but would like to have a good starting map.
If you have a build similar and would be will to share you map, it would be appreciated. As a side note, this is going into a 1986 Lotus Esprit (mid engine with transaxle). This was one of the reasons I went to the mechanical LS1 throttle body (and the MEFI4B only works on mechanical throttle bodies)
you can reach me at dlgsmith2@yahoo.com

Stock is a good place to start..
Input your injector settings, lower timing in the higher airmass areas to start, then run it to start adjusting fueling.
