Hi,

After searching, Im coming up with not alot of info.
I need to find some MS-1 install instructions/ECU pin-out for a 1.8 1998.

I've got an LC-1 to install with it and the MS-1 is a DIY kit fully build and working on a stim.

Cheers,
Craig

The problem is that the Miata was never sold as a 1998 model year in the US. Is this one an NA or NB body style?

it's an NB

What Richy said!

It's an NB and timing is off the crank. I'm guessing here, but if the 98 NB was never sold in the US, should I be looking out for the 99 NB ECU pin-out and MS-1 install instructions?

I'll be wanting to install it parallel with the stock ECU as I believe the alternator is regulated off the crank angle sensor.

Thanks,
Craig

Go MS-2, read

and especially the latest thread from Abe about his adapterboard.

Im not too keen on going MS-2. My requirements wouldn't take me beyond an MS-1 parallel install. I just want decent fuelling/ timing control for an intercooled supercharger install with the ability to bang in some larger injectors etc.

I don't see an issue with letting the stock ECU control the alternator and other boring stuff.

I'm still struggling to fins a defined pin-out/install guide for my 1998 NB car :(

That is how I did my parallel install as it was with the MS1.

No guarantee though, it's just a little drawing I did for myself...

With MS1, you will have to add an NA cam sensor (or a 36-1 crank trigger), as only MS2 can read the stock sensors.

Thanks for the schematic Zaphoid.

I've got a mk1 CAS for the back of the exhaust cam so hopefully I'll soon be on my way.
