OE Development ECUs...

Was chatting with a colleague at work today about Megasquirt and he asked me why I wasn't using a G400 ECU out a *******! I hadn't even thought about it to be fair, but we (Pi Shurlok) have in the past sold G400s with a full software development platform. Obviously we don't sell those ECUs now as they have been discontinued, but second hand ones are easy to come by. We even have some existing strategies that can be used.

[/EDIT]Not allowed to mention which ECU were using at Pi, in this case[EDIT]

Interesting What do you mean by a software development platform?
How tuneable would it be?
Is is ODB2 ?

Limitless tuneablility.

When I say development platform, I mean that you could develop your own strategies.

When you say OBD2, what exactly do you mean? The standard software would be junked in favour of some proprietary software. You could potentially develop the software to include the OBD2 requirements, but really there is no need, as OBD2 is essentially legislated system requirements to satisfy Californian emissions standards.

I see.So basicallly a good platform for a developer if you were so inclined.

Well, yes, but you could quite happily use a strategy that is already developed, and then it's just a matter of tuning/mapping/calibrating it. I have access to existing gasoline strategies....including knock sensing etc. Not sure if it would support EGT, but I suppose you could fairly easily put together a small circuit to convert a thermocouple input into a standard analogue input on the G400 (I suspect)

ok..What software would you use to tune and log from it then ?

well if you go down this route and want to sell your ms let me know.

You would use ATI-Vision with an ATI-Vision Hub. There is also a possibility to use a free CCP application, but not so sure on that.

It will be brilliant experience for my new job role, as it goes, so as long as the ECU isn't prohibitive, then I think I'll be using it.

what's the new role then?

What were you planning on using the MS in though?

16vT in my Corrado

Ok.

For an older car like a Corrado, the simplicity of a MS system will more than match the functionality of engine and car.

I do agree, but in this case, it's actually more about experience with the products that I sell and support as part of my job. I think I might start off with MS though, as it's sat in the garage right now anyway.

The ****** ECU in question is from mk1/2 4 cylinder auto ******s, so not exactly up to date. That particular ECU just has more I/O, to support the auto box, that can be used for whatever I need. The complexity can also be adjusted depending on what you want from the ECU. For example, I could configure it to be as simple as MS to start with, and then build from there.

MS will give you a feel for the whole engine management and tuning concepts in a real world situation.
I'd concentrate on that first,remember it was originally designed as an educational tool.

I agree.
MS, if installed and debugged properly is a very good way to understand the basics of control, calibration and engine developement. Being an 'open' platform, allows the user to modify the firmware to have his own custom strategy, if I can call it that.
I have built about 50 of the things and still learning
