So...the guy who was supposed to fit and tune and ecu to my car is all out of parts and isnt going to have any for some time. So, i've decided to get a megasquirt II and fit and tune it myself (done everything else myself so far might as well do the computer too).

So what I need help with is:

1. Should I buy an assembled megasquirt or should I assemble myself.

2. What extras will I need to run my rotary setup, because im in South Africa which means i'll have to order from the states and I want to make sure i get everything ill need first time. (see setup below)

These are my main concerns...fitting it to the car and/or assembling it wont be too difficult i don't think, my problem is making sure i get and know how to add all the extra stuff that will make sure it works properly on my engine.

My Setup:

1. 13B Bridge Ported engine (was s4 turbo converted to N/A)
2. Twin throttle bodies (efi hardware from tweakit)
3. 4 x 550cc denso injectors (from turbo engine)
4. Standard 12A distributor and coils (from later model 12A i think - comes from 1985 car)
5. Haltech Throttle Position sensor on d-shaft of throttles

So what sensors, wiring, etc etc would I need to give me ignition control and a working engine. I want to get this right first time.

Please ask if you need any more info on the parts i'm running. Sorry for all the questions but im struggling to find info relating to the megasquirt being used on a rotary, especially with my ignition setup.

Any help would be greatly appreciated.

 

Also, how successfully could I run this setup with only fuel control and just use the distributor as per normal like with a carburettor? This would make things much simpler would it not? But I would prefer to have ignition control too it just depends on how difficult it will be.

 

There is actually a MS forum on this site. For technical advice, you should ask them.

I have a MS in my car runing as a standalone and it works great; however, unless you know how to tune, don't do it!!!!!
