So you've convinced me you don't need a break-out board as what you're doing is really a 1 off install so you've made an incredibly strong case to buy a proteus and wire it in and stop worrying about which features you'll need to delete to use the OEM connector, just cut it of and be done with the ...

I remember that my name is Andrey. That's a significant percentage of all things I remember. I do not remember all the details of that video, but 6 years after the video was made I am sure that it's outdated in many MANY ways. It is my recommendation to purchase a TunerStudio license in order to ge...

Yes - if you want to do any frequency analysis, anything in the class of clipping/averaging/whatever will hurt your ability to do so, especially if your analog front end has distortion near the rails or requires a significant period of time to recover from saturation. When you only care about in th...

Probably just me being dumb so apologies in advance. When I download the simulator and launch as in the video I get Not Connected. I have tried the com port emulator, as well as all other recommendations. I even created a custom rule for the ports in windows firewall and even turned off the firewall...

That rule only makes sense if you actually care about the signal getting clipped. 99% of analog sensors are either actually 0-5v, or ratiometric to their supply voltage, which is 5v in our case. So there's no reason to try and do anything useful with anything outside the 0-5v range. Outside that ra...

The energy is the same. 24v -> 5v is a 19v drop, across a 3.3k resistor is 5.7mA. The CPU alone draws over 100mA from the 5v rail (really from the 3.3v rail, but it's a linear reg, so current is the same at 5v). If divided such that the analog inputs could sense -24v to +24v, that's 10x wider range...

Neither is a direct input in to the controller - they're buffered by the opamp and 74HC2G17 respectively. The 2G17 has clamping diodes from the inputs to the power rails, and allows the input voltage to leave the power rails by one diode drop's worth (aka the requirement is actually that you don't ...

I am not 100% sure but it looks like it would not have worked without https://github.com/rusefi/rusefi_documentation/commit/d6226c71f914cfe24a1453b35e879fd945fd3353 Is there any overlap between https://github.com/rusefi/rusefi/wiki/Ford-Fox-Body-(88-Ford-Mustang-302-V8) and https://github.com/rusef...

Pull request sent! I'll post the link to this forum once it is approved.

https://github.com/rusefi/rusefi/wiki/Documentation-Workflow is one of the pinned posts on https://app.slack.com/client/T4NJHQ8QZ/CF8NQ1RU6/details/pins

Aaand that makes waaay more sense... give me a bit and send a pull request!

That's a gap and we maybe have to something better somehow. While we have a shit ton of amazing, not all of it is as integrated as it should be. That reminds me of https://github.com/rusefi/web_backend/issues/57 and we have to find a way to better integrated wiki, forum and rusEFI online. Yeah. I'm...

I have no resources or motivation to burn anyone. You have my full moral and limited technical support. If you are interested to give back to the community please consider following as many of the best practices as you personally find reasonable. Please consider documenting the pinout in a reusable...

Mark, those two paragraphs should be engraved in gold with a few other quotes of yours. That's now part of https://github.com/rusefi/rusefi/wiki/HOWTO-Make-a-PnP-board Ok.... I get it. Please see my prior post before burning me at the stake. I believe my reasons are valid. Whether you agree with th...

It's not for anyone but you....it is a development tool. It lets you easily change configurations and play with options until you are happy. At the same time it allows you to become family with the entire system, the entire WORKING system on a WORKING car. It also lets you show off what the product...

you mean for 12v input signals? The digital and analog inputs on Proteus are already tolerant of at least +-24v indefinitely without damage. Sorry for re-visiting this. I think I might be overlooking something simple so my apologies if this is my stupidity. In the below circuit it appears this conn...

60 pin breakout is open source https://github.com/rusefi/rusefi/tree/master/hardware/Breakout_60pin_EEC-IV-Connector also available on eBay David has just sent https://github.com/rusefi/rusefi/tree/master/hardware/Breakout_104pin_EEC-V-Connector to bad that one not yet on eBay Please remember that ...

you mean for 12v input signals? The digital and analog inputs on Proteus are already tolerant of at least +-24v indefinitely without damage. Wow! Well that shows my familiarity with this system! :lol: I saw the 5V supply to the op amp circuit and assumed it was 5V limited. Guess I didn't look hard ...

Well turns out most of those hall effect sensors still run at 5V so I should be good to run it at 5V instead of 12V and not worry about voltage dividers etc. As far as the voltage conversion for the 12V signals. I'm assuming I can get away with a voltage divider circuit with some TVS diodes and mayb...

My strong and last advice get an old ECU to steal the connector off, wire it to a a proteus and get the car running. Actually see what everything is and does, what you like, what you feel you're missing, then, and only then, pick up your p&p project again. I say this because you said you have n...

Ok. So I'm starting to answer my own questions. I found the AT pins for thermistors on the proteus (guess I'm blind). From the diagrams it looks as though analog and digital are all 5V? That leaves me with a few dilemmas... 1) I've got a few 12V signals I need to read for trigger etc. I'm guessing I...

Thanks for making sense of that mk e! I'll probably leave the stock O2 connected to those pins then if I have the room (which I should). Personally though I'm pretty lazy and if this onboard wideband O2 controller works ok then I can get along with $30 sensors and have accurate readings too which wo...

I would suggest the stock pins for O2. It will either be a 0-1V or 05V and software setup. I was under the impression that the stock O2 sensors were pretty much useless for tuning? Are the stock NBO2 4 wire? If so you have everything you need right where you need it for something like this https://...

Sorry for spamming! Just a lot of info to go through. Here's my revised pinout: https://i.ibb.co/HxwQh23/mustang-EEC1.png https://i.ibb.co/R2J4VDN/mustang-EEC2.png https://i.ibb.co/YNKhDq9/mustang-EEC3.png I've added pins for two widebands (ya know, two just in case lol), and one electronic throttle...

Also, I'm thinking about coms now. I see that a few rusEFI boards have Bluetooth built in but proteus does not. Is there a reason for this? Can I put an on-board Bluetooth and it work with proteus firmware? I'd prefer not to have to go crazy adding external connectors on this thing if possible. For ...

Had a thought tangent. In order to get extra pins by utilizing some I'm "deleting" but not risking damage from a rookie plugging in a stock harness I could do either jumpers, or solder. I'm thinking if there's physically room the jumpers would be more "user-friendly", but I'm not...

mck1117 nice work man! I'm thinking about adding this board jumpered onboard my 5.0 mustang proteus if that's ok? Since it's still in dev I figured it's probably best to do a jumper rather than directly print your schematic on my board since it could change. My experience with wideband O2 is limited...

Ok so took me way longer than it should but here's the preliminary pinout: https://i.ibb.co/CVKM2KQ/mustang-EEC1.png https://i.ibb.co/C1Pt6mV/mustang-EEC2.png https://i.ibb.co/Cmr7dpw/mustang-EEC3.png Please double check behind me that the signal levels are correct. Red is what I'm adding (optional ...

Will that trigger pattern work? Yes, if implemented, it'd probably run fine. Is it better than a crank mounted trigger with tens of teeth? No. Agreed completely! My main reasoning for wanting it to work is not so I can use it necessarily, but so it would truly be "plug-and-play" for the m...

Not to say you should stick with it....just saying if you already have it there is no performance gain in removing it to switch to waste spark or directfire. You definitely have a point! I'd really like to get the stock TFI working if I can because it would save me from buying all those extra parts...

Oh neat, your engine actually has the same firing order as my LS, but the cylinders are numbered differently, so it looks like a different order, but it's actually the same one! haha got to love how ford numbers its cylinders! I'm more of a gm fan myself, but my buddy is die-hard Ford so here we ar...
