Tim,

Like on the new CPI2, we'd try to eliminate all external select switches and the mixture knob, having these functions controlled at the display.

We've done a lot more investigation into displays now, trying to listen to the feedback from people to keep it small. We're evaluating displays which will have a mounting footprint of approx. 3.25 inches wide and about 3.5 inch high (rectangular). This is about as small as practical for the functions to be properly usable.

Ross,

I suspect your done our about to be done with upgrades on the list....but...

I would like to see an output to trigger a warning light when preset limits are violated.

I.E. out of range volts, our out of range temps, or out of range AFR....

May be even a way to hold one of the existing buttons down for a LONG press to display error details.......or flash an error code momentarily for that particular out of range issue.....

There has been a check engine light output available for many years on the EM-5 which flashes when any out of range condition happens- low voltage, high or low, temps, MAP. There has also been AFR lean warning and auto richen for many years if you have a wideband hooked up to pin 24 and the window enabled.

Some basic decisions have been made on CPU and display hardware for the EM-6 after working with an evaluation board version of the CPU for the last couple weeks. This CPU choice will involve learning its ins and outs but will ultimately speed development of other aspects of the ECU and its new features.

We have a reasonably defined development path now to follow on the new design, so can finally start ordering some of the bits mid week to begin work.

Excited to have gotten many of the big decisions out of the way after evaluating the pros and cons of several choices. We didn't choose the easiest path but feel this is the best path to allow future growth of the product.

Barry got a new eval board last week for the exact CPU we plan to use which has breakouts for all the pins- really nice. He's been studying the architecture and playing with it a bit when he needs a break from the CPI2.

He's itching to get at this full time as it's new and interesting. I have to keep him on the CPI2 for a bit longer though and get it completed before he gets unleashed to start writing code for the new features using this micro.

Default Display

We're getting a few questions about programmer size to allow for from people planning their panels and using an EM-6 down the road.

While we haven't decided all the details on the display layout yet, we have picked the basic display now. The original size we wanted was simply not available in quantities of under 1000.

All I can say at this point is to plan for a square footprint of 3.5 X 3.5 inches which is about the same size as the present programmer behind the round cutout.

It may be closer to 3 inches tall if we decide not to use any external keys independent of the display but the width should be under or at 3.5.

Ross - any update on the form factor for the controller on the EM-6?

Built an off-plan 9A with too much fuel and too much HP. Should drop dead any minute now.

We've settled on the TFT display for some time but recently had some discussions about other possible interfaces such as iPad or Android tablets communicating through Bluetooth. Bluetooth has its own issues sometimes though.

Some people prefer a cabled, panel mount solution, others a wireless, more portable one.

The drawback to third party solutions is you're at their mercy if their software updates cause something not to work down the road and the wide variety of software and devices in use. We don't fancy that scenario much from a time and support angle. We are leaning back to our own, cabled design as a result.

There is some other technology we could use in the future to eliminate the panel interface entirely for many people but that hinges on how new fuel availability plays out and the timeline. I see us needing an interim human interface solution before that bigger leap takes place although the tech to do it will already be in the new ECU anyway.

As far as exact size and layout of the panel controller goes, nothing but preliminary layout has been considered at this point. The CPI2 project takes most of our energies at the moment.
