2ms pulse for 7 seconds when starting

Post by Jim Blackwood »

MSv2.2/MS-IIv2, MT2.25b695, Monitor_v2.36.abs.s19 file, Olds 215 V8 with blower. When I crank to start I get a 2 ms injector pulse width for 7 seconds, then pw jumps to 6ms and the engine starts and everything appears to work normally.

Priming pulse: 3.0
PW @ -40*: 24.0
PW @ 170*: 6.0

ASE: 30% for 250 cycles

Any ideas on why this happens? (I'll run a datalog)

Thx
Jim
