Cast Crank Sensor Bracket & IAC port

Orange Claw Hammer

So, this week I found time to finish machining my 36-1 teeth into the stock pulley and cast two more pieces for the EFI conversion.

 

First is a bracket to hold the crank sensor from DIY AutoTune:

Second is a small plate with a port to connect to a Suzuki Swift IAC (idle air control) valve. I'm not 100% sure that this IAC will allow enough air flow for the M10, considering it's from an engine with half the volume, but I had one easily at hand, so I'm giving it a try. I'm going to mount it to the underside of the intake using two pre-existing bosses and a custom bracket.

There are two smaller ports underneath my IAC inlet plate. One goes to the fuel pressure regulator, and the other I will use to provide a MAP reading to the ECU.

 

These two cast pieces really could be a lot more attractive and look more like "car parts" but right now I'm going for functionality and ease of production. It's amazing how quickly you can turn a piece of scrap aluminum into a usable part. The IAC plate took just 90 minutes from start to finish.

 

I think my next step will be building the wiring harness, which will probably take a while because I will be ordering new connectors and pins to make it from scratch... I don't like splices.
