MS kits

[neobudda]

im just curious, how hard is it to put a megasquirt together? I mean I know im gonna get one but im not sure if I should get a kit or a pre-assembled one from some place like DIYautotune.com

oh and what about wide band o2? I think that one would be easy to assemble but maby I should just by both pre-assembled at the same time?

[S.Bretz]

Its pretty easy. The first 20% or so of the guide is lists of components and how the guide works along with how to solder the joints. Once you get threw that, its just step by step and pretty easy.

yeah if I can do it than aney monky can

beside the actual module for the MS, what other components do you need. i guess u'd prolly wanna upgrade ur fuel pump too? oh and how much will that entire setup run, cause i wanna use this when i go turbo.

[BC. Livewire]

most of us have found that the stock fuel pump is good for 300 HP

[S.Bretz]

The walbro 255lpr are good for like 500-600hp...the stock pump is 190 (on most years, lets say 91-96 to be safe) (190/255)X100= ~75%. sooo, on the low side, of my estimate, 500 X .75 ~ 375ish.

So 300hp is a good border not to cross. You don;t want to go lean, and to insure this, you change the pump before it becomes a problems. Also, a stock pump maybe able to move 190lph, but at what pressure rate? It will not be able to keep up the good pressure liek a walbro. And when you think about it, you will most likle be spening major bucks to get to the 300 mark safly...heck, you will probably have 600-800 in jusr rods, so what is another 100-125 for a fucking fuel pump? RIght?

I do a gree with SAM

I see I may have jumped into the middel of this thread

sounds good with the pump, so can u answer the other part of my question? would i be needing some wire harnesses, the pigtails for the injectors? i know i'll need injectors past like 200 hp, which i'm sure i'll be putting down more than that. will i need a laptop with the programming to manage the MS?

[JustinL12086]

You will need a laptop to get the files loaded into the MS, and for tuning. After you get it perfectly tuned though, you can leave the laptop out. As for wiring, you cut the wires running to the pcm, so you will be using the stock wiring harness with the MS harness spliced into it from inside the cabin. I bought my MS from sparkandfuel.com I could have built it but after spending all the money that I did to turbo my car, I wanted to just start the car up and not have to worry if I messed up when soldering the MS.

You'll need injectors for anything more than 1psi.

[JustinL12086]

Actually I ran the 19lbers and they are good w/ 4psi(spiking up to 6psi) up to 4000rpms. lol
after that since they are maxed out, its scary wondering when they will
lock up. but they will fuel the motor w/ a 11:5 afr up to 6500. But again, I wouldnt recommend it. I have 550cc injectors in now.

EDIT: Oh yeah and as far as problems what I'm referring to is jumps from 11:5 afr to 13:5+

[punkboySL2]

ok, cool that helps a bunch, thanks.

[kyle.quamme]

Anyone have a diagram of how to splice the wires so the MS will work with the PCM?

[S.Bretz]

Use the wiring diagram provided my the Mega Manual and cross refrence it with one of these.

alright, sounds like i have all the stuff on paper that i need, now i just need the cash!
