Fabulous feedback, Stevie, you have literally written a very sensible list of things I would certainly want to see in the ECU, so much so I have coped it off and added it to the appendix of the spec
I am always confused as to why they have maybe 4 or 8MB of internal logging.... I can buy a 64MB flash IC from Farnells for £3.60.... 128MB for £4.55.... I could put an SD slot on for 12p, (though I am against this idea as it opens the ECU up to contamination), though perhaps the best all round method for 8GB (GIGA) of storage would be to have the SD card slot internal, install the SD card at production and make it secure against the inside edge of the case.... inexpensive MASSIVE data storage...
Just my thoughts as to that one...
Also, re. MoTeCs software unlock.... I think this can give a bad 'tinge' to the product. The main reason for this is that yes, the 'hardware' is there, so you should have it, as you have it, but, its the software that ultimately costs the money to write, hence why they do it. Autodesk inventor CDs don't cost nearly £10k a time print... so I can see both sides to that one, though, the public, will always be on the side of the a tangible thing already being there, the hardware... Its not a method I would use on our new system though! If its there, you can use it

Hi Matt - Out of interest what price point and target user are you aiming for?
Obviously this will incur limitations to hit the market you are aiming for..
I am interested in one of these - but as one of the guys not running a cossie budget price point is always a issue for me (hence me having a megasquirt already)
Also how are you looking to offer things like pinouts for wiring? Low and High impedance injectors and things like this.
I am a novice mapper - it may be an idea to have a log of certain (known) components that work with it, for instance in my installation the engine is virtually standard ford Sierra 2L DOHC 8V as a learning tool, so I would want to be able to deal with a ford Idle Speed Valve with the coilpacks from a zetec, ideally without the additional wiring headaches of the EDIS module (3 wires this way rather than a handful more to get confused with), ford TPS and even a ford MAP sensor (im using the megasquirt map sensor in my build) and the standard injectors.
some good base maps to get started with would be a good idea as well!
