MS II 3.0 2.905

i finally got my motor fired up with a junkyard distributor. it had a rough idle so i data logged it and for some reason the timing is jumping erratically back and forth from 15.8 to 3.8 When i watch the timing table its rock steady in between 2 cells. both cells and all the surrounding cells are all approx 15.7 ish degrees. the trigger offset is 10 deg. in tuner studios like i mentioned, the table shows a steady dot in between to cells but the gauge in the instrument cluster is jumping from 15.7 to 3.7 deg. any ideas what would cause this. i searched the forums but didnt find anything.

attached is the data log. it gets an idle at 1931.000s

thank you,
Vic

i just swapped out the junkyard ignition module with the new ebay distributor ign module thinking...hoping it was a bad module but it is still doing the same thing with both ignition modules.

oh geez...im an confused person. i had my rev limiter set at lower 5500 and high 600 rpm with 12 deg ign retard as the limiter.

Yep... That'll do it every time.

Glad to see you got it sorted out!
