ECMLink V4??

Posting specific topics on videos you'd like to see would probably be more helpful to them so they know if they can knock it out quickly or not.

I think when they said that they would post a video about wot tuning, but that never happened.

WOT for a MAF? If so, you don't really need a video to describe what to do, and that info has been posted around here at least a few times.

WOT for SD is a much more involved video and would probably take a lot of time to really explain well.

Dare I even suggest such a thing?

We've gotten a few question asking us what V4 is going to include now that V3 is out and working well. These are typically joking questions, but it does lead to some thought.

Two of the biggest limiting factors on our ECUs are I/O and RAM space (internal working memory). We only have so many inputs and so many outputs. You can log wideband data and boost data and, depending on the ECU, one or two other things on the given pins. Many pins have special considerations too and if you're running a factory Mitsubishi mass airflow, you're limited even further because it steals two of the inputs you'd otherwise make good use of (IAT and baro).

And then there's the output side of things. We provide full "parameter"-ized, windowed control over the EGR and FPS outputs already and we'll add boost control via the WGS output soon enough. But there are plenty of situations where people would really like to have even more outputs to do things like drive external shift lights or trigger a separate knock warning LED or a coolant-temp warning LED, etc. But we're limited to what the factory ECU provides us.

And then there's the RAM space issue. This is more an internal restriction we're forced to deal with in terms of functionality we can add and how we can add it. But this certainly affects the end user too as we'd like to do a lot more cool stuff inside the ECU that we just can't right now (ECU auto-tune for example).

To address these issues, we're giving some thought to an entirely different hardware approach. For the non-EPROM 1G (and soon 2G) ECUs, we already have a conversion board that basically "hooks" into and intercepts the processor pins. From there, we can do a LOT of cool stuff we can't do out on the EPROM socket.

If we were to develop a similar board that worked on both non-EPROM and EPROM ECUs (basically removing the processor and installing a special board whether it's an EPROM ECU or not), we can do a lot more stuff. We can add more analog inputs for datalogging, digital inputs for external switches, digital outputs for various things, MUCH faster datalogging than we do now and more extended RAM space which means more functionality.

The problem, of course, is that this conversion is relatively expensive. Figure on $95 for the conversion and then some dollar amount for the upgraded functionality. Maybe $175 would make sense as a V3 to V4 upgrade and you'd *have* to send us your ECU to do it.

So, given that, the obvious question is...how many people would actually be interested? People were VERY interested in many of the new things we added in V3. But now that that's out and working well, is there anything else people are really wanting? Let's hear some ideas!

Can we bring this back please!!! I want a v4 and I’m ready!!! It’s been 13 years!! We need a v4

It's definitely an interesting idea, especially now- at this point once you run out of sensor inputs the only real options are to go to linkg4, or haltech/etc

@twdorris is there anything cooking on your end?

I suspect the issue is the limitation of the 2G (and worse yet, the 1G) ECUs.
There is a baro sensor mod you can do to the PCB, if you're brave enough. I'll be doing it so I can wire in a fuel pressure sensor.

Please document that @curt-s . Very interesting and something I haven't heard of.....until now

This one maybe?

Yes, thanks Steve! Since it was a 2g deal, I hadn't read it but am always up to playing with circuit boards

 

[curt-s]

yep, that one. There's anecdotal evidence here on this site that one has tried it themselves and it worked, likely within reasonable error too.
Guess I will see too..
I just hope the sensor doesn't do something stupid and fry my ecu.

I have this removed from my 2g ECU and am running a fuel pressure sensor on that input without any issues.
