The first of many stupid questions
I have been reading through the stickys but decide on exactly what i need to get the job done.
Starting this winter im going to be building my own megasquirt ecu. between my dad and i we can get the thing assembled, no problem there. but cant decide on what parts i need to put into to get the right outcome. i want it to be a standalone system, the car has had the ac removed so that dosnt need to be wired in. oh and i want to keep it MBC. What all should i need, to do it correctly. |
I believe your first of many stupid questions is missing a question.

you need MS unassembled kit, get atleast pcb v3 and MS2 or MS3
|
addons cards? wiring harnesses?
|
wiring harness you can do a couple ways, I cut apart another ecu to get its main connector out and wired up wires to the db37 soldercups that come with the kits.
I just bought some wire and did mine up, or you can buy diyautotune's colored coded wiring, they also have prebuilt harnesses. Check their wiring componets area. you haven't said anything that I noticed would need addon cards. |
I would also recommend a wideband if you don't have one already. I'd recommend a slc oem one if you want a good cheap one. If you want one that has a gauge readout, I'd probably go with a innovate MTX-L
|
I wonder if you read the "How to build your own Megasquirt" thread by Brain. I am pretty sure he included a list of parts as well as a detail step-by-step assembly process...
|
soldering iron, solder
|
i did read that thread he mentioned some addons and i was wondering if i need them for my particular application. does the ms have fan control.
|
programable outputs, so yeah its on there how to drive the fans
|
You decided to ditch your half ass pos bandaids and go ms.
You are not stupid after all. Good luck. The amount of info about ms on this site is staggering. |

i have had the intention of going ms since around june, but havnt been able to afford the pnp. im going to save up and build my own. its cheaper and i will understand it better. thoughts on the tester device? |
One bit of advice for reliability. Do as little hacking on your stock harness as possible. Get proper connectors to make a patch cable into your MS.

I'm not sure, but I know they are available. Do a search, I seem to remember someone posted links to a source.
In my case, I just went MSPNP . . . problem solved. But it is more expensive, and I often wish I was MS2 or MS3 based. It is really easy to change tunes. Takes about 5-10 seconds. However, I don't think you're going to find it necessary. Generally, you select between the "race tune" and the "economy tune" with your right foot. |
just wondering if you can program it to have warnings/ do something about a problem. lets say a/f ratio drops below 12:1, i would like a buzzer or something to go off. and maybe within the ms change settings automatically.

I used this for building my MS2 and it was HUGELY useful. That was my basic "guide", supplemented by some sticky threads in here for things like fuel pump mod. |
Also, for the harness I would spend the $$$ on a DIYBOB - http://www.diyautotune.com/catalog/d...pin-p-411.html
I imagine it would make soldering the harness way, way easier. |

Who sells the needed pieces. reliability is a must. how hard is it to switch between a couple tunes. im thinking a Good MPG tune, Race tune, and a split between the two.
