I cannot find a thread on the conversion for the A12.

Is there a thread for this swap? I saw an old sales thread but no info other than it was for sale.

I bought a SR20DET CAS Dizzy.

I want to give this a decent try.

SR20DE Dizzy conversion for the A12. I don't recall ever seeing that. What is your goal, what are you trying to do?

My goal is EFI and Better control of spark delivery. EDIS is an option but this seem to have a High resolution for spark control.

Haha that is not a distributor, it is a CAS sensor. I'll update that page.

It is actually a combo Crank Angle Sensor AND a Cam Position Sensor. For a bit more information see the overview at D4P.

Nissan optical CAS/CPS unit can be used to trigger MegaSquirt ECU for electronic spark control of coil packs. MegaSquirt II with the latest firmware download can use the stock Nissan trigger wheels, while other brands of ECU generally require a swap to a special low resolution trigger wheel. There are a lot of older writeups on the low-res trigger wheels because MegaSquirt was only updated a few months ago.

CA18DET and E15ET use similar CAS units. Which is why the D4P article has some info on it.

Haltech makes excellent products. I remember they were the first after market ECU I heard of back in the 80s.

Haltech ECU
* $939 AUD and up
* proprietary
* professional help and documentation

MegaSquirt ECU
* about $700 AUD fully assembled or $500 mail order from USA
* open source
* user-based documentation

MS I would only recommend to DIY users.

I loved the prospect of Haltech being able to fix maps and tweak my product remotely if needed, but MS is a local favorite among the speed tech shops. Can't go wrong with either choice.

I'm machining some ITB's for my A12 this weekend, along with looking for what else I need for the build.

Heck I still have the DOHC A12 hanging from a motor stand...... It's on hold for a spell.
