Saw this on other forum: srtforums.com/forums/showthread.php?t=239763

Anybody had any experience with this? It sounds very promising to those with the proper technical know how (which I lack). Looks equal parts complicated and fucking badass.

i currently have no experience, however, i am seriously considering it.

if i do it, i'll be setting it up for fuel only, then setting it up for spark later. at the very least, i like the idea of controlling fuel without screwing with MAP voltages and therefore messing with timing

The learning curve looks brutal, but I'm considering trying to run one of these instead of my SAFC. It's obviously a vastly superior tool for the same price. I could see these things becoming quite common in SRTs.

I could see these things becoming quite common in SRTs.I posted about it a couple years ago now on the other site and they've just recently decoded the stock crank position sensor trigger. A few people should have it up an running on the SRT-4 in the next couple months. You've been able to use them for a while now, but would have needed to use something like an external Ford trigger wheel and coil setup.

It's vastly superior and also vastly different. The S-AFC is just altering the MAP signal, but if you go this route you'll need to run extra injectors and use MS as a fuel computer, take over full control of the injectors from the factory PCM, or use it for spark and fuel. It won't (easily) be able to simulate a piggyback in how it alters the MAP signal, and I don't know why you'd want to. It can do much more than that.

I consider my piggyback as a poor substitute for an EMS. That's how I was comparing them. :thumb: :lol:

I have been looking at it for a while too, and it was the crank trigger that kept me away from it. I will probably build one for the 1st gen turbo and use that as a testbed.

Seems a lot more 1st gen cars and other 2.0/2.4L powered turbo cars have had good success using it with (Ford) EDIS. I'll eventually get around trying the setup I have planned.

ive actually read through the megasquirt pages and gotten a lot of information as well as checked out their forums that include success stories. I have to say it does look interesting. It may not have all the features that a "commercial" stand alone might have, but it has a few things going for it:

1) Relatively low cost
2) (Seemingly) easy to use software
3) Its a completely open project, i.e. source code for firmware, schematics, etc etc (a BIG plus in my book)

If a solution has been found to use the SRT's crank angle sensor, then this is a great option for the DIY person IMHO.

I have a kit here I haven't assembled yet. It's for a turbo 455 Buick project that I've been accumulating parts for, it's going to be a long winter project.

Didn't get a chance to check out the link but one of our N2MB guy's (SpecJ) has it installed in his SRT. We're dyno tuning it sometime this week after we finish up our customer's EMS tune.

Seem's like a pretty cool tool but you really gotta know your stuff to work with it. He's our best tuner and is very confident with it.

My Megasquirt should be coming in any day now. Eric has suggested that I "build my own standalone" more than once and now I am finally taking that direction. The trigger points still need figuring out, but after more of us install it into our SRT's it shouldn't take too long to have an SRT-4 specific setup.:thumb:

i'm very interested marc... keep us updated. i'm subscribed over there to all the EMS threads, and i have to say, MS seems to be my favorite so far :thumb:

I haven't been keeping up with it for a long while, but your other free/open engine management system is VEMS.

http://www.vems-group.org/

It's always been a cluster that they keep adding features to instead of fixing problems, but I don't know if that's changed or even current development work. I'd personally stick with MS but you might want to look into it.

Ehh. The moment I saw "euros" I steered away.:lol: I've received that useless USPS shipping info from RS Autosport so I'm expecting my package any day now. I was seriously considering mounting a Trigger wheel from an Escort and just running an EDIS setup seeing as how our coil packs are actually compatible. This would have allowed me to run the MS2 daughter board and have MUCH better control over the injectors (0.01ms instead of 0.1ms). In the end I opted for a preassembled MS1 with the V3 board and MSnSE. I really need to get a degree wheel while my motor is apart so we can physically verify the trigger points that boost junkie has configured into his NGC decoder firmware.

Just updated the thread on the other forum. Here are some pics that I posted...

awesome marc.... i've been following the thread over there too, jsut reading though :lol:

i'm about 90% sure i'm gonna do this, but if i do, i'm gonna build my own for sure... i have an extensive background in electronics, so at least i can do that part with no problems :lol:

i may have to look you up for some help once you get it going :sneaky:

For sure I'll help you. We're still having trouble getting the trigger points just right, but we're still making progress. I have to edit a few of my pics to reflect the new findings.

i'm kinda hoping (although it might be asking too much) that i can get it to run with no codes... then i can leave it in for emissions... but if i have to take it out, i'll just make it as PnP as i can

I actually have a similiar goal. I just don't care about the emissions aspect. I'm no hippie.:thumb:
