Megasquirt Vs. DSMlink

[Jepherz]

I have only ever heard of 1 DSM successfully running Megasquirt and that's a 2G in the Omaha area, if that says anything.
Actually, I believe the first guy to run MS in a DSM was a 1g. His name is prez on the boards, so if you search DSMToonerz you should find his posts. H was from Omaha I believe, but when I had met him, he had just moved to Des Moines. This was around 3 months ago???

If I had the option I'd give Megasquirt a shot. But from reading up on it, MS seems to require some hacking of the timing components before it'll read the signals from the crank and cam angle sensors correctly.

i bought and assembled MS2 with the v. 3.x board and i haven't installed it on my quest because converting to MPI is more money than i care to spend on that engine at this specific time. maybe later. but in the meantime, i'd like to find a good candidate for my MS. maybe the lawnmower. how cool would a turbo'd 50 hp push mower be?

edit: oh yeah, the main reason i replied was about spark control - MS2 has either hall sensor or VR pickup for timing. i was planning on using an MSD flying magnet wheel on the crank pulley. and origionally also a 6AL with a 2 step box, but i found that you can install a high current circuit to drive a coil directly from MS2. and i figured there's probably some software that allows me to have a 2 step anyway.

that may not happen on that car now.

The majority of the people out there don't need aftermarket ECU's because they don't have any clue how to tune. If an inexperienced person feels the need to tune his/her own car, just be sure you're prepared to swap a blown head gasket or build a new engine. I'm not saying anyone is experienced or not experience, I'm just pointing out the obvious. I'd say most people don't understand how an S-AFC affects their tune.
As far as DSMLink vs. Megasquirt goes, DSMLink is ready to work right out of the box. It looks very user friendly. It's just a matter of tweaking fueling/timing tables for your specific needs. MegaSquirt is closer to an old school DFI. It was not built vehicle specific. You can get a ballpark tune, but it's not like starting with a bone stock Mitsu image.
Depending on how much power you want to make, an EPROM ECU with a custom chip may be the best and cheapest alternative for you. In the end, whether you're using an SEFI8LO, DFI, MegaSquirt, DSMLink or stock ECU w/S-AFC, if you understand how to manipulate the fueling/timing maps to get what you want, it doesn't matter how you get there.
Ask yourself these questions. What is my target A/F ratio? What is my target total timing? If you can't answer those questions, it's best to let someone like Shane tune it for you.

thx for the advice all, i have decided dsmlink, i do appreciate all the help. now i just need some $$$. (u guys rock)

I use dsmlink and love it. The support forum is second to none also.

I've always loved the idea of megasquirt, but like its been mentioned... you can do it much more simply by just getting DSMlink. I'm sure sometime in your life you'll come across a car that will need megasquirt because there will be no other options.

AHAHAHAHAHHA!!!! shane you shoulda been tuning that thing!!

woot, drive 'em in, push 'em out. :D

I have no idea why it takes 35psi to make only 450whp on a turbo that big, and then somehow manage to blow up the motor. Even weak 7-bolts can handle over 500whp and back when I had my 7-bolt 2.0l and a little 54-trim stage 2 turbo, it made 450whp at 25psi.
