i pulled my computer out of my car a few days ago to test another one i had modded for a friend with with PRJmod. after i put mine back in it something strange started happening. whats is happening is my timing gets severely retarded on every up shift and there is definite loss of power for a second till timing catches back up. like when the throttle closes, i shift to the next gear and than reapply throttle timing goes anywhere from -5 to -22 degrees than advances itself to the proper timing value after a second or so. its is very annoying when driving. so far i disconnected my clutch switch thinking it may have been activating for some strange reason and that did not cure it. anyone have any ideas what would be causing this timing retard to happen because i cant think of anything. i'll post a screen grab of a data log of it doing it to show whats going on.

How can you tell us your spark advance degrees if you don't have a single log file to post? Also, in other thread you have posted that you have knock advance, can it be the case in here? -
i actually figured it out. somehow capicitor C106 was hanging half way off the motor chip board. it was vibrating which led to it making/breaking connection and causing all kinds of havoc. i replaced C106 with another out of a parts ECU and it working well again. i think my ostrich cable hooked on it and caused it to break off."The really good drivers got the bugs on the side windows."

Those spark advances -5 to -22 are based on what?Comment

1. Use winlog to log if you want any support.
2. Motor chip does not know anything about any knock.Comment
