1997 miata...

gonna buy this:
MegaSquirt-II Engine Management System w/PCB3 - Assembled Unit DIYAutoTune.com


I'm going to mod with all of this:


idle air control:
PCBv3 -- PWM IAC Valve Control (TIP120) 'Mod-Kit' DIYAutoTune.com

Boost control:
PCBv3 and v2.2 -- Boost Control Mod-Kit DIYAutoTune.com

and from what i have seen here, i don't actually need a kit to run the fans, just move preexisting circuit around?
Megasquirt 2 Mod Kits - Miata Turbo FAQ

use this to connect my ECU to the engine harness with the 64 pin plug.
18" MegaSquirt Pigtail Harness DIYAutoTune.com



ok so this is what I'm looking at. building a megasquirt from scratch is a bit over my head and i have a friend that will do the mods for free. I'm ok with wiring in the harness, just not the micro board stuff.

am i missing anything? are there any more mods you'd recommend? id also like to go Speed Density eventually so ill need an IAT sensor eventually.


on a side note… with all the time and money in this kit (just over 500$, would it be worth it to just go with an already ready to go MS by Reverent? ~700$

Unless ur very confident id just get one built, u know its tested and has all the mods u will need ( u can specify ) and some awesome support from the builder. To me the extra money was worth every penny having Reverent build it, id do the same again.

missing the ms3 cpu.



If I was building one here's what I'd order:

MegaSquirt-III MS3X Expansion Card DIYAutoTune.com

MegaSquirt-III Engine Management System w/PCB3 - UnAssembled Kit with black case DIYAutoTune.com

MSPNP and DIYPNP IAT Sensor Kit - Steel Bung DIYAutoTune.com

and follow this writeup: 90-97 MS3 with MS3X | My Westfield MX5 90-97 MS3 with MS3X | & Megasquirt site




or add:


23" MegaSquirt Wiring Bundle for MS3X DIYAutoTune.com

MegaSquirt Wiring Bundle - 23" Long DIYAutoTune.com

and the same 64 pin connector and make a harness. (I prefer the harness myself.)

I'm really considering reverent. I've been looking at the money and it's only another 150-200 for peace of mind. More research!

Just did exhintake, lost ALL bottom end power below 5k. Got to figure this out...
