Miata Coils Wiring
2 Attachment(s)
Hi there,
I am currently wiring in a Motec M8 into an Toyota 3S GE engine using Miata coils (running wasted spark)... I would like your help figuring out the coil wiring. My coils are as follows https://www.miataturbo.net/attachmen...ine=1425775484 Just want to know how to wire them basically, what is trigger, +12V and ground. Are these coils of adequate quality. The car will be N/A so no need for very strong ignitions. These are smart coils correct? They have built in ignitors?? Sorry I searched but couldn't find this info an no adequate wiring diagrams. This setup is not mine, Im just finishing this project and doing the tuning on it. Thanks! Paulo |
Hi,
Please can someone help me on this? I recently powered up the ECU (Motec M8) and the coils overheated a lot...theres certainly something wrong with my wiring. Can someone help? Regards, Paulo |
Your vehicle is not even a miata :dunno: Sorry bud, no idea.
Others whom have built miata specific looms may chime. Best of luck to you. |
Hi
Thanks. Ive found some wiring diagrams and I think Ive got it. From the right, when looking to the coil terminals, its, 12V, spare, trigger and ground. I will try that today and see if the coils keep cool. Thanks, Paulo |
FINALLY
So Ive worked it out.
I downloaded 2 mx5 wiring diagrams, one for the 4 wire type coils and one for the 3 wire ones (different model years) Both were wrong and produced no spark. The final setup that worked was: 12 V Spare (previous tacho) Ground Trigger In the both diagrams the trigger came between the 12V and Ground...not on my coils... |
How shitty are the 3S-GE coils that a Miata coil is an upgrade? :party:
|
Nice input lol
This is a budget build...MX5s were available and they had to do. :dealwithit: |
