how?

+1 also will be interested to see your knock monitoring project!

I was tapping a wire for 12v and i had left the ignition on. Rookie mistake. Nothing related to the ignition system. Its been a step by step process of building, testing, implementing, building, testing implementing... the implementing process involves tieing the DIS into the car wiring. One sub circuit at a time. Well as I was doing the last circuit, I shorted it.

Man that sucks. Are you going to pick up a stock ecu or something like nismotronic or standalone system?

Ive been looking at a MS. It seems to be a pretty good testing platform. Although it has COP capability, I can run it in "distributor mode" for testing. And it will be cost effective on the 99. I'm not sure what I am going to do yet for the 00. I really need a b14 or b13. I do have a b14 GA I can put this on too.

I forgot to add. Just before I fired my ECU, I was able to completely isolate the cam angle sensor and eliminate the internal coil from the system, while maintaining tach signal. Looks like a CAS will be next. If anyone has one they are willing to loan me, shoot me a pm.

Interested for sure in this product. Thanks for doing the R&D.

And we are up and running. I repined the ecu harness and installed a spare b14 ecu. Remember guys, always isolate your power source BEFORE working on the elecrical system.

First test drive after permanent install complete. Drove appx 2 miles with no issue. OOOOhhh, yeah its not much, but its huge for me.

The pic I attached is something I want to show you guys. It is very important that anyone interested in this project to understand what this pic means. This is the display of my oscilloscope showing the ignition out put on cyl 1 compared to the ign signal input from the ecu. Now at the bottom you can see 0.00000s. This number represents the difference between the triggering of the out vs the triggering of the input. As you can see the difference between the start of the input compared to the output is less than a micro second (us). In fact it takes only a few nanoseconds for my controller to receive the input from the ecu and output the signal to the appropriate cylinder.

To give you an idea of how fast this is, it take the engine 0.006 seconds to rotate one revolution at 9000RPM.

That is freaking awesome amazing response time kudos to you on the design!
