May I ask:
- What basic functionality are you providing to the chassis, without requiring additional, external hardware / devices? For example: what sensors and outputs for operating the engine and driving 'dashboard' features, tuning features, et cetera.
- What optional functionality will you be providing? For example: optional external engine operation sensors and user-interface type things.

Maybe I'm asking what "actual" functionality you will realize with this, and what parts are in-built and which require add-ons, whether internal or external.

Of course, and the answer is honestly "very little" as our application requires a maximum of two fuel two spark.

OUTPUTS
4 medium current low side outputs
4 low current high/low 12v/5v configurable outputs

COMMS
2 CANbus channels
1 LIN channel
Bluetooth

INPUTS
2 VR (1 channel optionally optical isolated frequency )
1 Frequency input MAF/Speed/E85 etc.
7 analogue inputs (3 voltage / 3 resistance / 1 either)

28 main functional pins with supporting IO circuitry and additional 68 pins brought down onto three headers so virtually full access to the mcu especially as the pins are mostly reassign-able.

So anything over the basics relegates the board to a cpu module and requires either add-on daughter cards or a proper high pin count base board with additional supporting I/O circuitry. The networking options discussed earlier will accommodate options like the Powerbox HP8440 central electrics modules or infinitybox multiplexed wiring

Firmware will be dedicated to FrankenCIS, any alternate application would have to be o5e unless our distributors decide to play in the vanilla EFI arena.

Looking forward to how this turns out.

Good that nobody (especially Nobody) was holding their breath in anticipation.

Yes, apologies, the current version has morphed into a configuration specifically for FrankenCIS and not currently useable for normal EFI.
We need to make a more complex and therefore larger board to get the requisite high current drivers back in. The elves here are currently looking at options but at the moment the MS products combined with our add on interfaces are doing the job.

I have unlocked this topic.

Explanation:
While I understand locking the topic may be desirable because of the direction things went, locking it prevents any further discussion regarding it from occurring.

To which point I will ask the following:
- what led to the decision to lock the topic?
- was there anything anyone could have provided that would affect that?
- what are the plans regarding O5E and this, moving forward?

Thank you for understanding.

That's fine :)

Given there is apparently a new serious attempt to create generic hardware for the project, I felt closing this dead one off would assist in focusing attention to the other. I also didn't want to reinforce the vapourware and "that guy" comments by projecting maybes over actuals.

We only seem to have upset one user here by our change of direction so the expense of developing something that didn't suit our target just doesn't make financial sense.

As for o5e and Qorivva, o5e is not compatible with our control strategies for the Bosch injection so we have written our code from scratch over a hybrid OSEK/Freescale base.
As for Qorivva, honestly, to get the advantages of the TPU and the compilers requires the licenced versions of the development tools which then takes it out of the running for the hobby/open community. Like your efforts with the o57t we are seriously looking at the Infineon Aurix Tricore range. Essentially as we have to pay for it we would prefer high end over low as we always have the megasquirt family for a budget hobby line. Commercially our clients are requesting more modern items for integration and control, meaning SENT based sensors, multiple CAN, Flexray etc. are all no longer quirky additions to our CAN and LIN modules but fundamental requirements for an aftermarket solution such as ours.

For giggles, did you know there is a Aurix based Arduino http://www.hitex.co.uk/index.php?id=3650

funny, I just bought what I'm pretty sure is infineon base HW to play with

http://www.aemelectronics.com/products/ ... ty-8-10-12

Which was designed by these guys:
http://enginelab.net/index.php

and it turns out you can dump the AEM contol model and create anything you please using the enginelab stuff

El Console is here if you want it:
http://gemellocattivo.com/forum/viewtop ... f=19&t=150

The model I'm building is here:
http://gemellocattivo.com/forum/viewtop ... f=19&t=153

Once I get it sorted and working I'll transfer it back into o5e which will hopefully be about the time the new HW is ready :)

Major eye roll is more like it. The Hitex board appears to have the TC275 in 176-lead LQFP but the standard pinout for the Arduino Due is 86 pins.

Are you taking into account the various power supply and ground pins the chip requires?
