thank you Aussie Driver, Al Hounos, MiataMath
 

just to give a shout out to three pioneers for helping me get my close loop tuning to an acceptable state

as my signature says, 94-M, with 00 block, 02 head, square top intake, BEGi 2860 turbo, MSPNP1 with VCM

finally found the following thread Miata Turbo Forum>Performance Tuning>MegaSquirt
"sticky" Super Important MegaSquirt threads>Settings

after several reading, I mostly duplicated the setting contained there
now starts and idles with no drop

if anyone is interested will post screen clips of my various setting

You must have been looking at threads from like 2007-8. These members do not frequent this site anymore and haven't in years.

Are you even controlling your VVT? It hurts my face that you're using a MS1 on a VVT motor...

yes to the threads -- shows the value still locked in the historic stickies

yes to controlling the VVT, using a DIY VCM [and the 94 CAS, and the 01 cam sensor, and the 99 crank wheel]

it will hurt even worst when I tell you I have a Dimitris built MS2E w/VCM just setting on my workbench waiting for the right time

I wanted to get the tune stable again before I replaced the MS-PNP1

once I get the MS2 stable, I plan to uncouple the LS coils and go sequential

target is > 300 whp [on the Mustang dyno], but we will see

are you available to do the MS1 to MS2 switch, and the pre-dyno tune?
