What a waste of a day off.... (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif)
I knew it was going to be one of those days when my laptop wouldn't communicate with the Link ECU, luckly I brought a back up unit that I normally use, it's just that the 1st laptop I had was way, way faster...(normally) Mark D (McMark) showed up and helped stomp on the gas while I played with the laptop, we started @ 1000rpm and went up in 500rpm increments...strange feeling with the pedal @ WOT in 4th gear and the motor would not go over the set load... I kept hearing a misfire and then all of a sudden under load it got real bad, we changed out the distributor cap since the original one had some viewing holes cut into it for timing....it just got worse...then I noticed the air intake elbow was a little loose so I fixed that...I was hopeing that was it...nope still really bad misfires coming out of the exhaust....finally I load a new MAP setting and the car seemed to be idling better, then all of a sudden the car dies..."hey Mark, did you turn it off???" "nope" "oh $hit" I get out the voltmeter, I have voltage like I should, no apperant spark.... So, it's one of the following I think (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) a bad MSD box, a bad optical sensor in the dizzy or the Link is messed up....I have a check list of items to go over before sending the Link back for testing.... I think i want to replace the optical sensor within the dizzy with a hall effect unit, any leads or ideas? McMark dyno's his car, I'll let him tell you about it...he had better luck than me |

Okay, that makes sense. Sounds good. I'm currious about the Link only needing it's signal 10 degrees before TDC. How does it trigger the coil at say 27 degrees before TDC if it doesn't get its input signal until 10 degrees before TDC? Does it count off 323 degrees before it fires (ie. it's always behind one rotation). My ECU get's its input signal at 44 degrees before TDC so it has time to "think" before firing the coil at up to 40 degrees (high vacuum) BTDC.
