Megasquirt Maybe?

Hey guys,
As some of you know I did a dohc head swap and then a small fire happend and fried a LOT of my stuff, now that as it may, the damage is a lot less than I thought is was.. It seems, now my question is should I go with MS and Boost it that way so I don't have to deal with Trying to tune with a FPR and wideband? Or Should I just try to find an SRT motor and call it a day? Ive done a little bit of reading but MS still reallllly intimidates me. I just don't have any idea what to do, I really need my car, and I really don't want another car payment you know? Is MS really hard to understand or is it just me?

Sugar coated:
It's pretty easy to figure out! Just plug in the right wires, and your car will fire right up!

Actually what happens:
You'll get the wiring in, and hopefully everything is tight and not noisy. Tuning will be a major headache until you figure it out. You'll bang your head against the wall more than once trying to get your car to run how you want it to.

See actually hooking up everything is what I was more worried about, since the fire fried my engine harness and parts of my engine bay harness, I'll have to somehow source new/used ones. I do remember seeing a link one day of the wiring diagram,Or at least what I thought was one for the neon, but I can't remember where. I know there are a few people here locally who have a little bit of experience with MS but I feel you with the whole banging your head against the wall, I just really don't know who to turn to or where to start on this. I have kinda reached the point of no return with this car since the swap. Im sick of driving my moms car to work.. Hell I don't even know where to even buy one at to even get started..

We can send you an MS.

The trick is going to be replacing all the wiring to power all the sensors, etc. A couple of them need 5v, which can be fed from the MS, most need 12v, which you'll want to play with at the fuse box, etc. Something that's nice though is that really the only engine wiring you will need (to run the engine anyway) is to keep the throttle position and crank position sensors alive, in addition to the +12v ignition hot coil and injector wiring.

I knew you guys sold the whole turbo kits but I didn't know you were selling MS Separately, Really would be interested in purchasing an MS unit from you, seriously. Shoot me a PM if you want or give me a link about price and I will buy! Are there instructions to get started or will I be pretty much on my own?

I guess I will seriously be whoring up this forum to learn more about what I am getting into...

We sell them, but we don't really want to make a ton of sales out of it. We barely make enough to cover shipping on them, and it's hard for me to justify making $3 on a MS with all the support I have to provide after the sale.

I understand man! Especially with the kits that you are putting out, it would seem that you already would have a lot on your plate.

It's not so bad, but I already spend a couple hours a day either helping out on forums or locally for free. When it's free, there's less liability. When I'm charging someone for parts or services, I'm at least morally obligated to make sure it works. That's the draining part.

Yea I know how that goes, I guess whenever I get around to doing this, I can always search the forum or talk to chris or a couple of other guys here locally, The more I think about this, the more I regret not goig the MS route in the first place.. I guess all it took was a small fire to get my ass moving.

Bump:

Im lookin at diyautotune.com at some of their prebuilt kits on there and am thinking about purchasing one from there, is there anything that I should look out for, or any suggestions on which MS unit I should look into? Or what version I should go with, MS-I or MS-II

I'd really appreciate some guidance on which way I should go! This all this reading is making my head hurt!

MS2 makes things run a little smoother, but for basic tuning, there's no difference in capability. The MS2 does run a bit more like stock though, so you'll have an easier time transitioning to driving when the engine behaves a little differently.

Ahh ok see I was under the impression that there was a huge difference between the two. Its good to know the differences!

For what it's worth, the Megasquirt ECU's DIYAutoTune sells aren't pre-configured for the 420A/Neon application. They're a great company (we frequently do business with them), but you would need to do a little hacking to one of their ECU's to make it compatible with your car.

Our Megasquirt ECU's and kits, on the other hand, are completely configured for your application;
