[SPAM] Re: What do you want in an aftermarket ECU

[rapieper at yahoo.com (Ron Pieper)]

OK...my advice, remember this is a design project, not necessarily a marketable item - follow your
own advice and *narrow it down* to what you can realistically accomplish well.

-go to msefi.com and absorb everthing you can.  Download all the apps (they're free and open
source)
-ECUs can control fuel or fuel+ignition.  Choose one.
-Limit the types of engines (even # cyls, forced induction or not, even fire only, etc.) and fuels
(pump gas only)
-Power and economy can be achieved on the same map.  8x8 is OK, 10x10 or 12x12 is better but not
overwhelmingly so.
-If ignition, the perfect system would have onboard knock sensing
-Fuel should use narrrow or wideband o2 sensors.
-User-friendly, high-graphics software is a MUST.  It must be able to convey the feedback while a
driver is watching.  Ask me how I know.
-Decide on high- or low-impedance injectors (high are easier)
-self-tuning would be WONDERFUL.  Download MSTweak3000 and see what it does - it's not self tuning
but it's the best Megasquirt has right now.
-Price?  Cheap!  Below $500 for a full implementation, like Megasquirt.

HTH a little,
