George Posted May 20, 2019 Share Posted May 20, 2019 Has anyone done Ford EDIS coil on plug conversion on L series engine ? I set up edis 6 module of 94 explorer , using 98 gord escort trigger wheel and crank sensor with 2005 f150 5.4 coils tied cylinder 1,6 5,2. 3,4 car won’t run it backfires threw the carbs I have the crank sensor mounted on 6 tooth 36 to 1 trigger wheel tdc Quote Link to comment Share on other sites More sharing options...
NewZed Posted May 20, 2019 Share Posted May 20, 2019 What engine management system are you using? EDIS isn't coil on plug, it's coil packs, with one coil firing two cylinders. Not really clear what you're describing. Coil on plug is typically one power transistor per coil managed by the EMS, EDIS has it own separate control system. There's a couple of EDIS threads in this topic - https://forums.hybridz.org/forum/93-megasquirt/ Quote Link to comment Share on other sites More sharing options...
George Posted May 20, 2019 Author Share Posted May 20, 2019 I know edis uses coil packs but if you tie the signal wire to 2 companion cylinders on the coil on plug it is still a waste spark ignition Quote Link to comment Share on other sites More sharing options...

Have you checked timing with a light? You haven't really confirmed what you know besides the parts that you bolted on. "I bolted these parts on, it doesn't work." A common cause for backfiring through the carbs (some people call it front-firing, since backfire usually means at the exhaust pipe) is a bad cam lobe. Your problem might be mechanical not electrical. Have you checked valve lash and cam shaft quality? The short direct answer to your question in the first post is "yes, it's described in two of the threads in the link I provided". Good luck.

George Posted May 21, 2019 Author Share Posted May 21, 2019 The car runs fine with the 280z distributor installed and you can adjust timing no problem with the distributor and there is no back fire from the carbs with the distributor. I’m 100% I have no mechanical issues I’ll figure it out thanks anyway Quote Link to comment Share on other sites More sharing options...
NewZed Posted May 21, 2019 Share Posted May 21, 2019 Sounds like your timing is off, a light would show that, or you have your plug wires to the wrong cylinders, or you have some crossfire between wires. You still haven't really told anything about the engine management. You can't run EDIS using the stock 280Z EFI system. Actually, maybe you could but you would be stuck in "limp home mode", at 10 degrees. Assuming that you set it up right. Again, a timing light would show it. Good luck with your mystery project.

George Posted May 22, 2019 Author Share Posted May 22, 2019 It’s just a L28 motor with carbuertors in 240z I don’t have efi I said it was backfiring through the carbs there is no efi management system I’m trying to run edis 6 module with a MegaSquirt computer just to control timing advance plus i can’t get the engine to run with edis system to check with timing light I’ll post the setup when I get the engine running Quote Link to comment Share on other sites More sharing options...
