I think the LS2 coils have a built in 'dumb' ignitor, but since the AEM only has 5 ignition inputs, you will need to figure out something custom. The DH61 only works properly with the stock 7MGTE coils, or the 2JZ-GE wastefire coils (as far as I know).
You can, but it takes alot of setup fiddling to make it work properly. If you already have the LS2 coils, it might be worth it. Otherwise I would just stick with a wastefire setup - if you want to run pencil coils you can always get a CDI box that will drive 6 coils from 3 inputs on waste fire.
yes, i already have it :S so does anyone know how to hook it up, and by that i'm thinking in the AEM software.. I do know how to install them, but not how to "tune" them in AEM. Because i do need to use the 10injc driver as a sixth coil driver, and the LS2 coils need 5v signal, so does anyone know if the COIL signals from the AEM is 5v og ground signals?
not a good idea to run cop coils that are not waste spark type as a waste spark. ls1 coils are not waste spark and would not have enough time at higher rpms to charge properly before being triggered. waste spark are designed to spark twice per cycle and can charge properly in the half time allowed. ls1/ pencil coils have twice as long to charge before discharge so the coil is designed for this. same for ignitors. a 6 channel ignitor will calculate the tach output and a waste spark 3 channel will calc the tac differently since it expects to be triggered twice as often. thats regaurding toyota ignitors which calcs rpms for tach.
the aem has 5 coil channels according to their tech number. as mentioned you can use 0-5v to trigger the built in ingnitor coils but i think you would loose many other options these 5v pins did. also changing around the aem cal file to run that is a major pita. i would rather wire in a universal aem ecu than screw with that. the stock coils are rather good even for high hp. is300 coils very nice also. 3 channel ignitor to replace multi sh!t is great.
Depends on the ignitor - there are several CDI systems that can charge and fire pencil coils twice per cycle in waste fire configuration quite easily. Trying to use standard coil on plug with or without dumb ignitors in waste fire when it is not designed to do so can cause issues for sure.
your pins are correct. you may see IG1,IG2,IG3 as labels on the 7MGt side instead of using C1 etc as it will tell you your on the ecu side and not ignitor.
also remember if you check the wiring to the coils that coils are in the coil pack as
1&6 then 3&4 then 2&5 and installed in pack as
c1 then c3 then c2 for a firing order of (dont know why its not c1,c2,c3)
1 , 5 , 3 , 6 , 2 , 4
notice how the firing order goes left coil, right coil, center coil and repeats for waste spark, so trace all this and check the ign phasing order and you will be able to confirm that firing order. as long as the phasing fires the coils to achieve this firing ordrer in coordination with the physical wiring it will work.
It's because for the 7M, Toyota numbered the coils based on the cylinder they fire (1 and 6 is C1, 2 and 5 is C2, 3 and 4 is C3), so the firing order is c1, c2, c3, c1, c2, c3 etc.
For the 2JZ-GE DH-61 equipped cars, the coils are numbered from front to back in the valley between valve covers, (2 and 5 is C1, 3 and 4 is C2, 1 and 6 is C3) as the coils sit on cylinders 2, 4 and 6 and have wires running to the odd cylinders. so your firing order is c3, c1, c2, c3, c1, c2 etc.
So you need to convert the coil numbering from the 7M-GTE to 2JZ-GE formats. To do this you use:
Any 3 channel should work, but it might not drive the stock tach properly, and the dwell might not be correct for the coils you are using. This guide only covers using the DH61 to drive 2JZ-GE or 7M-GTE wastefire coils. If you are using the 300ZX coils, and can get the tach to work, it is an option.
To use pencil coils, you need a matching ignitor that has at least 6 channels (one for each coil). Alternatively you can set it up with a 3 channel ignitor in waste fire mode, but it needs to be an ignitor that is compatible with the pencil coils. the DH61 should on be used with the 7MGTE or 2JZ-GE Toyota waste fire coil packs. When going to pencil coils you remove it, and drive the 3 or 6 channel ignitor with the ECU outputs.
Could someone please post or PM pics of their DH61 installed and wired up in the engine bay? I think i understand the pin out and what needs to adjusted on the AEM software. But my car is in a shop right now getting some work done and i asked them if they could also wire up my DH61 ignitor for me. I sent them a link to this thread, but they said they never done it before and dont feel comfortable wiring it up unless maybe i can get some pics.
It would be Kool if we had tech YouTube videos made by members that showed the community "how to"
Don't get me wrong all the good info provided to us on this forum is great but having a video would help.
