Is this a feature I get to pay for?

Had to look up "bit-bang" as its been far too long since I looked at serial signal processing. That's software emulation for UART hardware, correct? If I'm understanding it correctly that would require firmware modification on the part of the MS. It seems like a no-brainer for something like the MS3x series with its myriad of I/O options. You said its been mentioned, but have any of the DIYAutoTune guys confirmed its been perused at all?

I have decided to re-float the idea of a serial wideband interface in the MS3 Developer's forum: Megasquirt MSEXTRA / MS3EFI • EGO data via serial interface from Innovate LC-1 / MTX-L? (View topic)

PLEASE do not jump into that thread and start crapping it up with a bunch of wild nonsense. I'm hoping to judge whether there is a sincere interest on the part of the developers to consider such a feature.

Haha, well that didn't take long.

Turns out that MS3 can already take in serial data from the Innovate, simply by using the JBPerf TinyIOx board to convert it to CAN data: Megasquirt MSEXTRA / MS3EFI • TinyIOx: read LC1 digital data (View topic)

So problem solved.

Default Connect your Innovate wideband via serial.

I split this discussion off from the "Fishes" thread to avoid cluttering it.

Long story short: you can now connect an Innovate LC-1 to the MS3 using this little board:

Dood! It wasn't me!

Neat infos here though, I'm seriously dusting off the ol' brain library with this stuff

Of course, I would need a MS3x first...

I just wanted to add that the TinyIOx will also connect to an MS2 or DIYPNP or any other Megasquirt ECU that has a CAN port.

I thought I remembered seeing your name in the thread on MSExtra where folks were custom-hacking this into MS2. Couldn't remember with certainty.

I'm going to go out on a limb here and suggest that a market exists for a little external box which has a 3.5mm TRS jack on one side (Innovate serial) and a DB-9 (or similar) on the other side to connect to power, ground and CAN with a Megasquirt. If it happens to also support a couple of additional ADC inputs or whatever that's fine, but I think that MS3 now has enough native I/O on-board that this isn't a requirement.

Whether the person who brings this box to market is Canadian or Greek is largely irrelevant to me. (Though to serve customers in the US market, they would be wise to set up a stocking distributorship with DIY.)

DIY already has a product coming out that will allow this albeit not in a minimal setup. Their upcoming CAN-EGT box has a 2.5 mm jack (the Innovate cable is 2.5mm not 3.5mm) and the code needed to read the LC-1 data.

And I'm not sure there is that big of a market for a dedicated standalone box. It wouldn't be difficult for someone to put a TinyIOx inside a small enclosure with an additional connector.

I have a feeling that a lot of neat new stuff that Rev came up with has been halted by the whole licensing drama, and now slowly one by one others are bringing his ideas to the market........

..maybe I'm wrong.

I hope I'm wrong.

Rev is not the only one who has been limited by licensing. and this has nothing to do with licensing (and even less about stealing anyone's idea).

Oh I'm not accusing anyone of anything. I'm not on the MS forums or within that community, so I'm probably wrong. It just looks that way to us mere mortals

I understand this but I have had the possibility of reading the LC-1 serial data in my IOx since mid-2010 so seeing the suggestion that I might be copying someone's idea is annoying.

Sorry for the necromancing, but is there any chance of this same capability for the PLX wideband sensors? I almost wonder if the protocol might be very similar (same connectors). I know it's serial communication to the gauges, I'd have to imagine you could pull that same data out of the stream. Thoughts?

This is from this thread. Reverant makes a digital wideband CAN module that supports a few widebands that use serial. PLX is not on the list but he might have added support for it since then. I'd send him a message.

It doesn't require any configuration on your part.

It's sole purpose is to connect to one of the widebands that have a digital output (Innovate LC-1/LC-2/MTX-L, AEM UEGO, AEM Inline UEGO, Zeitronix) and feed the digital signal from the wideband to the MS2/MS3 through CAN Bus.

This makes sure that whatever your wideband is reporting (and whatever you are seeing on the wideband's physical gauge/display) matches with what the ECU is seeing. Ie zero offsets.

As an added bonus, this method will also refresh faster on the AEM and on the Zeitronix, which have highly filtered outputs (especially so on the Zeitronix) and will also remove random noise from the AFR signal.

Finally, if communication is lost with the wideband or if there is a reported failure from the wideband, the module will report back "14.7" so as not to trigger any more EGO corrections and make it lean out or go stupid rich.

I think the tinyiox might support the plx too.

Dont think it does actually
