I got my timing meter and hooked it up last night. My truck was 5* ATDC at idle, moving to 9* ATDC at 2K. Putting the Lumi probe in and I started the engine to watch the pulses, that was one of the coolest things I have ever seen. I may even take a video of it and post it for anyone that has not seen this. Seeing the combustion happening was cool. I noticed when you let off the throttle from 2K there is no combustion while the engine is winding down, I didnt know it did that. No wonder these things slow down so fast when you let up.
So I loosened the IP and 4 injector lines and using a prybar and a ratchetstrap I pulled the IP towards the pass side as far as it would go and tightened it all back up. Now I am at 1* BTDC at idle and about 5* at 2K. Does that sound right? the engine retards 4* from idle to 2K?
This is as far as I could get the IP. Any advice on moving it farther? I was thinking maybe if I loosened all the injector lines. They look hard to get to without actually removing any lines.
The seat o meter saw no difference but there does seem to be a little less smoke.
I can see now why people like the pulse method better, I noticed right away if you dont have the lumi wire just right(as straight as possible) you can get erratic readings.
