Just a quick question. I've been asked by the guy doing the loom for my track toy car which pins on the ST205 dizzy relate to the cam position trigger. It looks like it should be the pin labelled 'Ne'. Anybody care to confirm? |

Hi, iirc, NE is the crank trigger and the G2 the cam home signal hope it helps, and if not you just have to change the two wires on the ECU, on haltech it is pretty easy as you have a table where you can see both signals counting, cank has two times the counts of the cam, so pretty easy to do the job  greetz |

NE is effectively crank trigger. Either G1 or G2 for cam wheel. From Memory, G1 is the one that activates for No.1 firing so is probably the one you want. |

Thanks guys. I was thinking that as the COP cherry hall sensor uses a single slotted disk mounted on the exhaust cam wheel I could use the Ne signal? Is G1 better from a cam timing point of view? It appears to e 90degrees offset from Ne. Am I being dumb? |

viewtopic.php?f=13&t=5973&hilit=crank+trigger&start=46 Also, something I wrote a long time ago when researching signals ready to install my new link G3. I have made the assumption of injection during intake stroke to conlude that G1 is just before No.1 firing. I would probably want to repeat a plot of dizzy signals vs. scope probe next to No.1 plug lead to be 100% certain. https://dl.dropboxusercontent.com/u/831 ... ignals.pdf |
