I've decided that I want to run Megasquirt on my 6 port bridgeport FC. I've put about 4k miles on it with the stock ECU and an SAFCII. It runs okay, but not near as well as I'd like it to run. I like the idea of building my own EMS, and can't wait to start. I've been lurking around this section and msefi.com and heres what I've compiled to get me started:

V.3 kit from diyautotune.com
Stimulator kit
Relay Board Kit
Build a harness with new connectors and whatnot
LC1 wideband
Run MSnS-E with the stock ignition (what's a v1 chip???)

That is about all I've come up with right now, I'm sure I am missing something(s).

Is there anything else I should be looking into before I jump into this project?

Thanks, Jacob

 

The "v1 chip" is the original MegaSquirt chip and is the one that has rotary ignition and fuel support. The MegaSquirt II chip will not work for us "yet". You want a V3 board with MS 1 chip kit.

so if thats the case we cant buy pre assembled v3 boards?
or do they offer them with the v1 chip

 

As far as I know, diyautotune offers them pre-built with the ms1 chip.

The relay board kit is only really necessary if you're going to redo your whole harness from scratch... and even then it's not totally necessary. Really it's up to you, but I've never used one... on tofuball's car we stuck with the stock power components and wiring, and rebuilt the rest of the harness (the two parts were separate anyway). The only other car I've had a megasquirt on is my S4 that I built the plug 'n play harness adapter for.

 

I too am looking into building a megasquirt system over the Christmas break. I am wanting to install the system in my streetported GSL-SE.

TwistedRotors:
Are there any disadvantages to using the "V 1" chipset? Does it make the board just a Megasquirt I?

 

the chip and the board have nothing to do with each other...

there is an ms1 chip, and an ms2 chip, a v2.2 board, and a v3 board...

the v3 board is compatible with both chips, as is the v 2.2 board.

The v1 chip's biggest disadvantage in practical application is that it has less resolution when tuning fuel... the ms2 has microsecond control over the injector pulse-widths, where the ms1 chip has only 1/10th of a millisecond. That's not a huge problem though... I've never really noticed any problems because of it, aside from at really low pulse-widths, changing by .1 ms can change the AFR significantly.... but there are ways to tune around this.

Also, to run the ms1 chip on a rotary, you upgrade the firmware to msns-extra... If you have not yet read the FAQ thread, I'd suggest doing so.

 

Well I just ordered my Stimulator Kit, hopefully this project will actually get somewhere in January.
