Quick update: Hard wired the system in today minus the completed proto-board. Cleared up 90% of the misfire issue. After setting timing repeatedly, I think I have a good idea of what is going on. Seems that with the timing set at 15, it idle rough and misfires a bit. increasing timing to 20, the misfire clears up significantly. This really should be corrected with a daughterboard. Luckily I was able to find the address location for the dwell/voltage and dwell/rpm. Looks like I have to pull the trigger on that and get it installed into a spare b14 ecu and go from there. Realistically, I think this will benefit the most using a Nismotronic ecu. But that's for much later. However now that the basic test platform is assembled and seems to be idling very well, I will move onto the second portion of the design.
This is the main purpose of the concept. The initial platform was designed off of the ls2 coils due to the simplicity and cost effectiveness of external coils. However the design principle is the same and the circuit does not need to be modified at all. So the next real update should be substantial! Proto-board is being had built now using a home made method of etching with muratic acid. Very time consuming. So please bare with me. I am aiming to have a few people running this mod in a few months, they know who they are, and IF all turns out well, beta boards will be available around convention time. Thank all for the support!
In the mean time, if any one can chime in on the base timing issue I am having, I am all ears. Thanks in advance!

So you need extra hardware on the board to do this... Tagging off injector driver might work.. though the Stock ECU is sequence fuel it only has 1 IGN output.. you will need 4 outputs or 1,3 for Wasted COP.. Wasted works just as well too..
