It seems here recently, the spammers have gotten even more sophisticated. What's odd is what they are doing obviously takes a bit more involvement than just BOTs dropping new spam posts. The new generation of spammer replies to existing posts with links in their signature or weird links within the t...

No secrets about that project. It's an open source idea.

You should include all the relevant info into the thread so if anybody else searching for this info in the future happens upon the thread, it'll be useful to them.

I use the Moates QH and I have 2 of them, one for a backup. I also have an old TwEECer, but I haven't so much as connected it up in quite some time. There's word that it may not even work with my Win10 laptop. I don't think it's been connected to anything since I had my Win7 machine (of which I stil...

Start separate threads for each question you want to ask. When different people are answering different questions in the same thread, it becomes hard to follow and not very useful for others since the title can't be used to gauge the value of the thread content.

Thanks

...much much more complete of an answer than mine.

The byte-length does not dictate whether something is signed or not. The interpreter of the data decides that. In the case of offsets in branching opcodes, the 1-byte offset is always assumed signed so that it can branch forward by up to 127 bytes OR backwards by up to 128 bytes. Being able to decla...

Does that help?

Does the QH still read your XDT2 box? I haven't tried. The version of XDT2.bin that I have is from someone else many years ago that uploaded their ROM-dump. And I don't think there is an XAD2.bin floating around yet nor have I tried to get a dump of it. I believe it'll be the most interesting as I ...

bmasencup, I edited your post below to link directly to the pictures. Its hard to tell from the pictures, but the larger SMD (surface mount) capacitor with the X on top looks like it is starting to dome, indicating it is reaching end of life. At some point, it is likely going to need to be replaced....

How interested would you be in being a contributor for such an effort? Assuming it ever gets legs and grows beyond the idea-phase? I've purchased a BBAI64 and have been working with it for a few weeks now. Even the purchasing wasn't just a matter of pay your money and its in the mail. I had to submi...

...With the power of today's CPUs it should be trivial to emulate the code quickly enough... That is an interesting idea. I'd had the idea that emulating the processor was the way to go to get disassemblies. But this is interesting and it has me thinking it might actually be easier to write an infr...

I watch a lot of tech channels on youtube and one of the hot topics over the past few months has been AI-generated content such as AI-generated art. However one of the more compelling advancements in AI are the chat-bots. Up until now, they have not been that useful. But Open AI's ChatGPT is quite i...

Yeah I don't know quite what to make of the phantom sensor readings. That doesn't seem right, but I'm also saying that with zero hands-on experience with your strategy.

The jump in load is sure suspicious that something has happened. Can you tell what input caused the jump? For instance, did MAF voltage also jump at the same time? If not, then start looking for other causes such as misconfigured functions (extreme min and max values not represented in 1st column). ...

A vacuum or exhaust leak is going to make the sensor not read an accurate an signal and therefore provide an inaccurate signal to the computer. So you might want to focus on that first.... Agreed. ...You cannot run without the sensor - not unless you turn the sensor off in the tune, which is it sou...

Here's the pictures of the XAD2 EEC (97 Ranger 4.0L 2wd Automatic). I expected it to be very similar to the XDT2...but no. Here are the relevant pics: XAD2_Delidded.jpg N8065FB.jpg N81C66DB.jpg N70005FWCHCA.jpg And there are 2x of these chips. One (pictured) next to the 18MHz crystal and the other y...

A Google-search only found 1 entry for that Ford patent and it appears to be a rather poor quality scan of original paperwork: Official Gazette of the United States Download the PDF and go to p652. Here's an image of the text: FordPatent5506777_AICE.jpg I could zoom in and get the image bigger, but ...

Also WRT to the 12MHz chip, is the EPIC using a 2x multiplier to run the actual 8065 at 24MHz? I can't imagine it is actually clocked at 12MHz. Although the Explorer/Mountaineer weren't exactly performance applications. As for the chips, this is the 1st I've heard of EPIC & AICE. John mentioned DARC...

I've got an EEC-V XDT2 that was pulled from a 97 Mercury Mountaineer 5.0L along with the original engine that I put into my truck. I kept it stored, but never used it since I retrofitted the engine to essentially be a Mustang 5.0L controllable with a GUFx era EEC. I've been in pretty deep discussion...

I wonder if it has something to do with your definition file. There may be some setting the developer can do to NOT expose PID names in BE. Or maybe BE now supports def files that don't have the PID column, and thus if it doesn't exist in the def, the search doesn't show a checkbox for it. If that's...

BE's Find (aka Search) feature can do exactly that. Notice: BE_Search.JPG I can begin typing the PID, and BE is filtering through all PIDs, Descriptions, and Comments (checkbox select-able) for what I've typed. And as you can see, I've only typed "FN135" but "FN1358" is in the list along with other ...

...As far as I am aware inj pw is going to only change with maf curve (and inj battery offsets)... Not exactly true. MAF flow rate and HP have a linear relationship. As airflow goes up, so should engine HP production (ignoring changes in efficiency and parasitic loads as RPMs increase). Likewise In...

You mention the MAF voltages are getting up into the 4.65v range. But what kg/hr does that correlate to? Knowing that might help others producing your power numbers what to check. While its not likely a voltage problem, it still could be a fuel delivery problem. It's completely possible your pump is...

Here's a proof-of-concept proposal for a modern day replacement project: https://docs.google.com/document/d/1TWLUUfgSpIVzz9gle7WUy6p4ezxjRFnz/edit?usp=sharing&ouid=110013228213321924284&rtpof=true&sd=true Note this is not something that could be done in a short period of time. This is a fairly long ...

I have no clue what strategy you are working with, but it sounds like the threshold and hysteresis for transitioning between modes isn't set correctly for your application for the source modes to be jumping around like that. If you'd said that the source was consistent and was idle, then that would ...

So just to confirm, it was a series of bad brand new IACs?

How are you determining 0% duty cycle on IAC? Test light? VOM? Some other way? It makes sense that the IAC would have 12v since the EEC generally prefers to sink devices to ground in order to activate them as opposed to powering them. Thus you should be able to test that the IAC will open by manuall...

Once I get the document into a more polished and presentable form, I'll transfer it over to Google-Docs so it can be viewed and even authored by others. The other benefit of having it hosted in the cloud is edit-privileges can be given to contributors and changes made by contributors can be time/dat...

I've got a document written up that goes through everything I've researched and know right now. It's more of a proof-of-concept document than a design document. But I think it gets the point across, at least to those VERY familiar with the EEC-IV/V architecture. The document isn't "light reading". O...
