Interest in built MS-based ECU
Turbo Mini Forums

First, I'm not sure if this post is appropriate here so if not, I apologize and ask the moderators to simply delete the post.

I have been thinking about making an ECU based on the Microsquirt module (http://www.microsquirtmodule.com/index.htm) and the latest MS2/Extra code which would be a dedicated 4-cylinder ECU and have sequential injection and ignition and as many extra options as possible that the module I/Os will allow (second O2 sensor, baro correction, boost control, others?). There would be 4 injector drivers (peak&hold standard or optional, not yet certain) and 4 ignition drivers (high current or logic level).

Since there has been a request for it, this would be put in a ruggedized enclosure (http://www.cinch.com/products/transportation/modular-integrated-connector-enclosure). While this may be somewhat more expensive, it does provide an automotive connector and the needed heatsinks and does protect all the electronics in a sealed box.

I am also considering an option which would add an internal data logger and add additional I/Os which could include a stepper motor IAC controller.

What I would like to know is if this is something that would interest people here. This could be used with either a 5-port head with the siamese code (with or without staged injection) or with a 7 or 8-port head with 4 port injectors and standard sequential injection. Both of these would use the same code version. I still need to do quite a bit of work to know exactly how this will fit together. If I can get interest from a sufficient number of people (here and on a couple of different forums) I'll make this.

There is a thread on my forum on this (http://forum.jbperf.com/viewtopic.php?f=12&t=50) and I welcome any question or comment either there or here.

I would be interested in this

The megasquirt type stuff goes over my head, and I need a solution

Would it be able to run:
Boost control
launch control
traction control (not a must but it would be nice)

and have a CAN output?

Im just asking these without reading your link yet

someones desperate for more oomph!!

just bore it to 1380 Nic...

TBH im not ready for injection yet. However I do want to be able to datalog and use the sensors to run a digital dash

Actually that's a very good reason, the amount of stuff you can datalog with MS is obscene,

obviously...

boost,
rpm,
lamda,
water temp
IAT,
TPS,
ign adv
bat voltage

but also with added sensors,

speed
knock
air pressure
fuel compesition (% alcohol)
etc


you'll find yourself spending hours looking at graphs in megalogviewer!

also it shoulnt be long before somone markets an adaptor to log straight from MS to a usb dongle or SD card.

id be very interested, what kind of price are we looking at?

Pricing is yet to be determined but a target of $500-$600 should be realistic.

Sounds interesesting. But I'm still 2-3 years away from fuel injection for my car.

I would buy a kit from you Jean, but i'm looking forward to building my MSII kit (as crazy as that sounds), so I think I will pass on this occasion.

It sounds like a great idea though, and will deffinately encourage more people to try the siamese code route.

An interesting concept Jean...

Last night I though it was quite appealling but having now looked at the schematics I'm not so sure but, as Carl says, it's another way of encouraging people.

Especially as (I assume) you are suggesting a ready built system - I think the thing that puts a lot of people off at the moment is that no-one sells a ready built version of the MS2 with all the add-ons required to implement all the features of the sequential and/or siamese code.

Just one technical point - on the schematics, it's still got all the "bad" bits of the MS2 but also, it's only got the 32k version of the CPU. I thought you were struggling for space on the 64k version for all the tables needed for the siamese code ???

I think it is an excellent idea. It will also help people cut through the minefield of options that currently exists with the MS2/Extra stuff.

The bit that would specifically interest me would be the integral data logger. It's a pain having to deal with the laptop whenever you need data to analyse.

I'd buy one.

I would be quite interested in this too.

If something is worth doing, it's worth doing half of.

+1 for me too, id be interested some where down the line when i get my arse into gear

Yes i moved to the darkside

Instagram @jdm_brett

i dont have the confidence to build these things myself, id go down this route when i turn to injection.

This sounds like a great idea Jean....

Sounds great, just wish I understood what you said.
I must get round to some research, obviously you guys dont do this just for the love of it.... there are gains to be had, it just goes over my head.

I seriously doubt it!

Spot on Jean,

Schematics/documentaion being out of date ??? been there before !!!

Ready built is obviously good for those who don't want a total DIY solution, hence I think all the positive comments.

The bad bits, as you guessed I meant, the VR circuitry.... The value of "C31" has changed yet again, presumably another compromise as it's value should be determined by the number of teeth on the wheel... and the "new" injector drivers are worse than the MS2 version if you want low Z (like I do).

If you replace those on your own PCB I'm in favour but surely to do so you would have to "tap into" the card other than at its designated connector ???

For example PW2 and PW4 aren't available at the connector, if the schematic's right they go through other circuitry before the connector.

What schematics? The ones on the MicroSquirt site?

I'm sure your comments are valid Rod.

But this thread has turned into another that will put people off because it comes across as too techy.

The whole point of Jean's proposal is to make it simpler to implement so that the user does not have to worry about processors, drivers, Vr or opto circuits.

I'm fully supportive.

I want one for that car I don't own yet, but also have my eye on some wheels for it.
