I'm still operating off BE rev 5.185 (2019/10/23). It's not having this problem. As you can tell by the date, I don't update much...and it's things like this that discourages me from doing so. As old and mature as my setup is, I don't update unless there's a good reason to. Very few features are bei...

I'll start by seeing if I can get DFSO to work properly. I'm using the A9L strategy from BE database which defaults to having DFSO toggled on, but several of the scalars appear to be set to keep it from activating. At least in the version I have... DFSO likely isn't going to help with (manual trans...

...It seems like AE is too high (swings rich on closed throttle low load shifts when cold)... Remember Accel Enrichment only contributes while the throttle plate is opening. If the throttle plate is sitting still or closing, there is NO contribution from Accel Enrichment. The AE algorithm is essent...

Knowing that helps. PATS maybe?

But what the problem could be from here I'll have to defer off to others that know that era of vehicle better.

If the engine is otherwise stock, can you get your hands on another stock Crown Vic EEC to see if the problem is with the EEC you have (i.e. whatever got flashed to it) or with the rest of the setup? Based on the behaviors you are describing, either there's a more than 1 thing wrong with the wiring ...

I've written about this many times over the years, and this is a common problem. There are a few ways to help it if you never find what's actually causing it. But here are my thoughts: First, make sure that decels/closed throttle isn't going overly rich. If this happens, the Closed Loop operation wi...

Short answer is it sounds like something is mechanically "sticking." Either the IAC valve itself is not adjusting smoothly and either needs to be replaced or lubricated. Or there's some other air-adder that is intermittently allowing more air or blocking air when it shouldn't. The most likely culpri...

In the GUFx defs, the adaptive special idle cells that are part of FN1325 have been broken out as scalars: Z_LTMTB80 Z_LTMTB81 Z_LTMTB82 Z_LTMTB83 Refer to their comments for details. Note, Z_ADPSW will need to be enabled to view them. You can search them, but when Adaptives are disabled via Z_ADPSW...

Yeah I'm regularly having to clear the site of the spam. I get to it sooner than others. I'm sure at times, it's been up for a while. But you aren't wrong about alternative options becoming more and more attractive and affordable. All I can say is it's about time. There's a part of me that's sad to ...

...It just seems suspicious that I would need to modify the curve or slopes to that degree. I was under the impression a <=10% change is typical, but 30%+?... That is typical and it often does indicate there is a problem. The best I can offer is this, the engine doesn't care what you do to the tune...

Check that you've lowered the Injector Offset vs Bat Voltage function. The stock GUFx tunes have rather high values in there that add way more initial fuel than is needed. However this tends to affect the lower RPM/Load range far more than the upper. I have not looked at the supplied tune to know wh...

...The logs indicate that the truck does in fact idle between about 17 and 22 degrees of timing at idle. The base idle with spout out is set to 10 degrees... This seems like reasonable idle spark values. You might try lowering them, but while the engine is at those values, it probably is calm. But ...

...FN111 is 32 degrees across the board. FN112 i do not have any added timing above 140 degrees water temp... If your engine is proving temperamental at idle, then I'd say start datalogging and make whatever adjustments have your idle spark somewhere below 22. 32 seems quite high to me and may be t...

As I was reading through this, I was thinking that the Neutral-to-Drive Idle air adders needed to be upped...but the OP said he did that and he can hear it flare when shifting, yet the engine stalls anyway which gives credence to the theory that its too much spark advance. Higher levels of advance c...

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...
