** 240z was sold in 2012**
This blog has now turned into a blog for random car and electronic projects. The time and space required to keep the 240z project was not viable so it was sold. Life goes on and one day another will be purchased and that project will continue.
Currently, I am working on a project for a close friend of mine named Adam F. The project is a 90 BMW 318I with an S50 swap. As it stands, the motor is in the bay, but issues with the starting system (starter fails to engage the flywheel) has us re-thinking that part of the build. A quick search over the internet regarding compatible parts for the drive-train will result in a lot of possible and confusing combinations. For instance, the transmission can be from the M42 donor car, but the clutch and Flywheel must be from a m20. The starter is also from an m20, but the pilot bearing has to be a 325 e30. After must confusion and headache, we decided to just go with the stronger e36 transmission that originally mated with the s50. This way the odd frankenstein setup can be avoided.
Another task that's currently in process is the engine management. We are going to run the Megasuirt 2 ECU in full standalone configuration. After completing a successful megasquirt project on my own BMW e36, this seemed like the most economical choice. I just finished drafting the circuit for the add-on features of the megasquirt. This add-on board will hold the circuitry for: 6 ignition drivers, 3-wire idle valve, tach output signal to dash, and relay control for the electric fan.
Here is a screen shot of the circuit using PCBExpress.
All that is needed is to transfer the circuit to a pcb and etch.
This is the first board that is similar to the one above, but is missing the Tacho and relay circuit:
Update: 2/15/14
Pcb was etched using the toner transfer method and muriatic acid and hydrogen peroxide as the oxidizer. Drilling was with a 1mm drill bit from harbor freight. Still waiting for the IRFIZ34N to arrive in the mail from mouser.
