Love these videos. Learning so much from them. One question: How does the difference in the number of teeth affect engines in tuning and every day running? I map old Weber Marelli ECUs, which have 4 teeth, and I've never noticed negative or positive effects on the way the engines run compared to mapping engines that have more teeth.
Great videos, have you thought about making a video about tuning priming and cranking pulse on MS3? Something I struggle with and so do others I talk to. Thanks again for the great work.
I'm curious about your distributor conversion. It looks like the Accel module is mounted perpendicular to how Accel originally intended, so did you fabricate a custom distributor body to fit it? It's easy to see how your chopper wheel works for picking up engine phase, but I don't see how you're picking up anything from your 40-tooth wheel. Is there also a VR or hall sensor below the Accel module?
Great vid Andy. @9:00 Did you mean 60 degrees before BDC then of compression? I took this info from Manuals as 60 degrees before TDC as the ideal spot for tooth #1. Thanks in advance. Awesome series BTW!!!!!!!!
You said you set up your missing tooth so it's about 60 degrees before the compression stroke (240 degrees before TDC) is it critical to have a missing tooth wheel set up this way or can you do it anyhow as long as you don't end up with your missing teeth close to TDC?
@@AndyWhittle_HowEFIworks Thank you so much for your response. I honestly didn't expect one on a 2 year old video. Another question: Does the amount of teeth at TDC before the missing one dictate the maximum amount of ignition advance you can apply? For example if you had your missing teeth 30° before TDC would that mean that you can only apply 30° of ignition advance?
