Why is microsquirt not the default MS install?

[Dale M.]

Foriend of mine who put a Subaru motor in his fiberglass buggy, used micro-squirt and laments that it was to limited for tuning capabilities for him to get most out of his install.... He did not want to do a lot of mods and his "out of the box" unit is just not quite there for him, and he feels he would have better performance and tuning compatibilities with MS II....

And like most 2nd or 3rd generation "stuff" its more refined and more capable than the 1st generation...

What firmware was your buddy running?
uS supports the latest Ms2-extra FW //TunerStudio etc.

It's a pretty capable system these days, and IIRC the original uS setups had at least a couple add-on modules available.
(sequential IIRC, perhaps some more outputs)

It does have its limits though.
OTOH a 10+ year old v1.01 mainboard from the original group buy will still work fine with a MS3/MS3X, given a case transplant and some endplate work. (just not "supported", all the docs are written with V3 mainboards in mind, and they ARE better boards)

I don't know and didn't ask.... IT was just a offhand comment made one day at Auto-X event when we were chasing a fuel delivery problem (plugged fuel line)....

Ok, lets narrow the confusion;
MS-2 PCB3.57 http://www.diyautotune.com/catalog/mega ... p-171.html 444$ no loom
Micro-S http://www.diyautotune.com/catalog/micr ... p-131.html 339$ with loom

Both main boards are what I want in that they are SMC, and I plan zero add on solder. I'll use uninteresting injectors, not interest in installing a cam sensor. I don't feel that the brain cost is a big deal, all the hardware needed is going to exceed 1k no matter what path I take.

I'm still harping on the form factor of the parallel port connector as stupid. It might make sense if you don't drive outside, have a hermetically sealed cabin and are trailer-ed to locations.

This is what confuses me, micro-S is both cheaper with a proper form factor, and yet looks like the unwanted step child. There must be a reason for this.

Ray Greenwood has been mentioning the parallel port d-sub connector on here for 10 years. They are finicky in an office environment!

I knew I wasn't the only person to notice that a printer isn't expected to be reusable once it hits freeway speeds.

The only downside of uS is that it is what it is, with little>no expansion capability short of an IOX over CAN.
(IOX and children are admittedly pretty formidable beasts, but it isn't going to run sequential injectors or COPs if that is what you want to play with)

I'm probably cursing myself, but I have yet to have any connectivity issues with the DB connectors, nor do they appear remotely common.

I would prefer AMPSEAL, and if I really cared enough I could DIY, but in onsies they are insane $.

When they come out with a AMPSEALed/sealed MS3 based uS (all in one MS3/MS3X alike) I'll buy one.
(there is no "if", it's "when" IMHO)

But G, you don't drive like I do and this one of many reasons I am unwilling to re solder something middle stream.

[Piledriver]

Those ambulance style ceiling mounted consoles might be a good place for it.

"sealed" is great, but I don't recall seeing a depth spec

[Steve Arndt]

The big "cost" in some of these ECUs is the connectors. My Redline / 034 2C ECU has TWO (that is right, TWO) of the expensive connectors built in. All high currents on one connector at one of the ECU, and inputs on the other end. . It is one of the main changes from their base 1C to the 2C, the extra connector and layout. It works perfect, the AMPseal connectors are bomb proof for sure.

That is cow piss, and Round-Up run off, not water. Very conductive and corrosive!

I do like what I have seen with redline/043 as limited as it has been.

The lack of a high current fuel circuit or for that matter high current anything is a draw back to micro-s. But at the same time how much is a reliable connector and hardened enclosure that costs less, worth?

That's going to depend on the application.

For off road etc, sealed/all SMD etc is a huge bonus, and would take priority, or be a higher priority than the last 2 HP or MPG. OTOH cost/benefit comes into play.

OTOH any EFI at ALL is going to have more potential issues, for example ...when getting fuel etc from highly questionable sources during a race or in Podunk. Flushing/blowing out carbs is relatively straightforward.(except dual Webers in a full bodied bug, unless you are a tiny contortionist)

If it makes you feel any better I am working on a plug and play Microsquirt kit with the Mexican system. It's been slow going with all my other jobs but it should be a great asset to my lineup.
Hall dizzy or crank trigger, Wasted spark IGN4, My COP's or wasted LS2 CNPs, idle valve. It's gonna be cool.





I may even use the hall dizzy in conjunction with the factory coil and wires from simplicity



I even got new factory Mexican air filters



I should have the rest of the parts I need an a week or so to get some more work done on it.

How much would you pay for that option? MS3 + Expander on a V3.57 with ampseal connector like Microsquirt? Because I know it's not going to be cheap.

That will be awesome!

That does make me feel better, as in that is the first time I have seen a micro-S in mockup. Are you doing the usual relay board to retro fit a not originally FI base vehicle?
