Edis 4
Does anyone know if an edis 4 sparks at 10 degrees TDC even if not connected to an ECU? I'm sure I've read this somewhere. Kind of like a limp home mode. I can't find where I seen it now and know some of you have already some experience with Megajolt etc.

yes without mj or the ford box connected, you get 10 degree fixed
best way to run it first off to prove it works |

edis runs at 10degrees before tdc without anything connected to it. only use it to test the engine idles. if you try and drive the car with it like that with out the fueling setup you will have problems.
i think you may have read it in complete kit car mag Last edited by AshG : 12th December 2009 at 10:17 PM. |

Mine runs 10 degrees BTDC as Ford intended (its part of the limp home strategy). If your runs 10 degrees after Ash you aint got the trigger in the right place.....

And there is definately something wrong if the manifolds are glowing red hot !
Timing or mixture. |

If they are glowing red at idle then it's not really a problem - you can't do much damage at idle. If it is glowing red above this then it is running lean - or - you have an air leak in the exhaust. Often people discount the air leak theory but I've seen it quite a few times. The most dramatic being while running an engine on a dyno - one guy was mapping, I was running the dyno and another was lookout. We had the engine at 12000rpm tuning the top end of the map, everything looked good -exhaust gas temps near the headers were good. Suddenly there was a loud bang everything got very loud and my underwear changed colour. On getting everything turned off and getting in the dyno cell it soon became obvious that we had a problem - only half the silencer remained and that was glowing bright red! Turned out that with all the vibration the silencer had worked loose and was sucking as much air as it liked through the joint. The resulting burning inferno inside the can melted it!
