Tadek Posted August 9, 2006 Report Share Posted August 9, 2006 The MAP sensor is already on the MS board. You might want to order the upgraded version with two map sensors (one for barro correction) and for higher MAP Values. Standard is 2.5 bar. At least that's what it was when I ordered for my Saab. The upgrade is 4 bars I think, which might be more interesting for a highly boosted application. I do not know what exacly you are planning to do with the engine in the future.Cheers,Tadek Link to comment Share on other sites More sharing options...
Swedish Mike Posted August 9, 2006 Author Report Share Posted August 9, 2006 To make a long story short, what´s the main difference between the MS1 and 2 and all these versions? Like a jungle! Thanks guys, I´m a total MS newbie.../Mike Link to comment Share on other sites More sharing options...
FoundSoul Posted August 9, 2006 Report Share Posted August 9, 2006 Wow, really nice. We already got a 60-2 trigger wheel, is it correct to keep every 12:th pin to get a 5 pin wheel. Sorry, slow now...If the VS guys want to we could start a GB? I´m in, MS is perfect for this project./MikeWith a 60-2 wheel spinning at crank speed you'd have too many trigger events (that would be enough for a 10cyl). As per the ignition article linked above you'd need 5 teeth at cam speed which is half of crank speed. The good news is you can use a 60-2 wheel with MSnS-E or the MS-2 (with distributor) and use the wheel decoder feature. I don't have as much first-hand experience with the wheel decoder as I do with standard trigger wheel/distributor installs, but the guys on the MSnS-E forum, or the MS-II forum could help. The MS-II wheel decoder firmware is in beta right now and soon to be released, you can get the beta though if you wanted. The MSnS-E guys have been doing this forever.... www.msefi.comMSnS-E's wheel decoder can be used for wasted spark or COP as well, and the 60-2 wheel would work fine. This is much more complex though....And as Tadek said the MAP sensor is builtin to the MS and the standard sensor is good for 21psi of boost. I do have the 'MapDaddy' dual 4-bar sensor with baro correction, which is good for 44psi of boost. It works with any MSnS-E or MS-II ECU.To make a long story short, what´s the main difference between the MS1 and 2 and all these versions? Like a jungle!

This is cheap, feature packed, and works great. If you are running low-impedance injectors you should also pickup the ‘Flyback board kit’ as an upgrade to the unit.

Free MSnS-E firmware allows full fuel and spark control and a ton of other features. This unit is affordable, feature packed, and works great. Has several upgrades making the unit more robust and harder to damage with a wiring mistake. Also has circuitry to directly drive a coil without an external ignitor (with MSnS-E). No upgrade needed for low-z injectors. Kit is $189. Assembled units are $330.MegaSquirt-II PCBv3.0 – This is the latest/greatest unit with lots of new and improved features including a finer degree of fuel control (great for tuning idle with large injectors) and native ignition control. This is an affordable and feature packed unit that was just recently released and will be further developed to add more and more features over time. As this is based on the PCB3.0 it also has several upgrades making the unit more robust and harder to damage with a wiring mistake.

All of the improvements with the V3 board are listed here: http://www.megasquirt.info/ms2/pcb.htmThe main high level differences are that the uprated flyback circuitry is included so you can run low or high impedance injectors, there are several improvements to make the board more robust and harder to damage in the event of a mis-wire or overload event. A prototyping area was adding to the PCB, and several changes were made to prepare the board for the future including the now available MegaSquirt-II CPU and upcoming releases such as the GPIO and Router boards.

Sounds like a MegaSquirt-II PCBv3.0 with decoder is a great option for us.Probably ok to leave the ignition out for now and connect it later in version 2 of the engine right?I´ll search and try to figure out what I need for this decoder, would save some work./Mike Link to comment Share on other sites More sharing options...

Tadek Posted August 9, 2006 Report Share Posted August 9, 2006 This sounds like a reasonable way to go!I tried to get ignition running first, as my Saab had a very "rustic" mechanical ignition advance/retard. That was a pita and took me weeks, because of my little weird setup that I insisted to use After having figured out the ignition, I just swapped the injector wiring from the original ECU to MS and the car started up right away and was drivable!

Carbon_R Posted August 9, 2006 Report Share Posted August 9, 2006 Yes I know it streams to AIM and MOTEC but poorly. Its fine tuning is weak compared to others in its class. It is by far the cheapest thoughAnd CAN enabled Have you seen the firmware upgrade for the 034EFI, not too shabby.Raf Link to comment Share on other sites More sharing options...
Texas850Turbo Posted August 10, 2006 Report Share Posted August 10, 2006 So if MegaSquirt works so well, why do other EMS' cost double or quadruple what MS costs? Not dissing MS or anything, just wondering because this seems like a real good option against other standalones that cost over $1500. Link to comment Share on other sites More sharing options...

I believe it's written in C++ so anyone can edit & submit code/programs, it's basically a Linux EMS. SO you're not paying for a large company's name and R&D. Getting an assembled kit/box in December when I return from school, if there is a group buy, I'm in. Just installed an assembled one on a KA-T, soooo much easier.

Maybe you will not get answers to all your problems that you might encounter right away, but the forums offer quite good support. It is all a big family In any case if you do not try to have a too exotic setup, you should not get any problems. I wonder that everyone seems to be going for the assembled kits. Assembling them is half the fun. Well, maybe not for everyone... :D Link to comment Share on other sites More sharing options...

Lets set fine tuning and sample rates aside. Most lower end units lack features that most consider important, ALS, traction, launch controls, dynamic variable maps, sensor support, data stream........... If your going to piggyback get whatever you want that can control the functions you need. For a true standalone your going to get pissed in a hurry with a lower end unit.

Che'_Moderator Posted August 10, 2006 Report Share Posted August 10, 2006 Not to be rude, lol thanks for that line, but if you really think MS is on par with Pectel, Bosch, GEMs, Motec, you might as well buy an 034efiNever understood spending more on an intercooler than on EMS Link to comment Share on other sites More sharing options...
