Thread: CNP/COP conversion for OEM ECU

Awesome!

We are now Nismotronic powered. Played around with it a bit this weekend seeing how coil dwell affect idle and low load throttle response. Didnt get very involved though. I am converting now over to the 20v vc and p12 coils. Since these have a little different wiring, its going to take some testing to see what will work best.

Just about have the first PCB built. Bench testing will take place on Wednesday. Probably going to start working on and engine simulator to make some of the technical stuff a little easier to work with.

Very nice man. Great progress, keep us posted and pics are cool! Curious to see how the homemade pcb turned out and the bench setup you have.

I'll have some pics posted this weekend if the weather is nice.

No real updates lately. Been busy spring cleaning and getting the house ready for my sons birthday. Thanks for remaining patient.

Ok so while the controller is mostly been completed, a lot of testing is needed to ensure it is safe and functions though all sorts of conditions. So to have control over the conditions I will be building a engine simulator that will allow me to monitor much more data and make changes to the setup quickly.

The basic design concept is to have a 12vdc motor driving a distributor. This will allow me to grab the signal from the distributor and run it through my controller and spit it back out to the coils. To tie it all together with live data monitoring, I will be building it using a b14 SE-R harness, a NismotronicSA, and a JIMSTIM. To drive the 12vdc motor and distributor I will be using a Arduino UNO w/lcd that will let me see rpm and have speed control via a laptop.

Very nice process!

Once I have a suitable motor picked out I will begin building an adapter to couple the motor to the distributor. This is the basically how it works though, although the inputs and outputs have not been hooked up.

I was a little reluctant about posting my board, but considering this design didn't produce the best result and will likely meet the chopping block, I think its ok to share. This was made using a toner transfer process and then submerging the board in a chemical solution to etch away the copper leaving behind the traces. Its not a prefect process and takes some trial and error, but it is a lot cheaper than getting a proto board printed each time testing needs to be done.
