...if I turn the timing up on the distributor.. when I see what the timing is when i'm looking at the moates logs does the computer know I mechanically turned the timing up... The computer is ASSUMING the distributor is set to 10 BTDC. So if you set it to something else, it will NOT know that and t...

I don't know how the dongles are supposed to work, but I would've expected you to have 1 dongle that unlocks both if you have a license for both. But I also get how if you bought them separately how you might have 2 dongles. But I wouldn't be surprised if it is a bug in the software that assumes the...

It is technically possible to get a read of the original ROM you removed. But it'd probably be far easier, depending on your intentions, to look for a *.bin file of the original tune by searching for it via its catch code.

Thanks for clarifying.

Based only on the numbers along the side, I made an, obviously now, bad assumption that those were kg/hr values.

Assumptions...

I'm curious to hear what others say. I think this has come up before, but I don't recall the cause. It's helpful knowing that it happens with two different MAFs. But that only reduces the chance it's specific to the MAF. I'm suspecting it has something to do with a value in the tune that's misconfig...

The LMAF has a known issue with blow-thru applications. It doesn't work well in that configuration. However from what I understand, it works just fine in a draw-thru configuration, on both boosted and turbo applications. MAFs work by measuring the temperature of a heated-wire as the airflow blows ac...

...But how to keep those tuner products working ? Convince the writers to release their code ? Probably not. (and I don't blame them !)... Ahh your point was not about how things will progress, but how we keep existing software working as technology around us changes. I don't have a good answer for...

...Windows vs. Linux. I'm staying away from any recommendations as it often starts a flame war... I don't mind touching that topic. But I'm also not a doctrinaire. I'm a practitioner. And so I tend to follow the "Use the right tool for the job" philosophy. In some cases, Windows just makes sense or...

Very nice find. That's a setting I'm not familiar with at all. However reading more about it, it makes sense why it was added to Windows. What doesn't make sense is why they don't make it more obvious when this setting is what's causing older drivers to not function correctly. I'm sure that's probab...

I'm confused by whether you are genuinely asking or just posting a pic for shock value. The lack of info leads me to believe it's the ladder.

I was hoping if I typed enough words you'd have the info you needed to figure it out.

https://i.gifer.com/BGHZ.gif That will never get old to me. As for your question, I think that's right. However I've never experimented to confirm. I also suspect the original intent/expectation was intermittently faulty sensor/connection. In the case of 2-bank tunes, a single failed HEGO typically...

When I was in that phase of my tuning, I disabled Adaptive Learning altogether so they stayed at 1.00. Having them not adjusting let me see the LAMBSE error thoughout my logs. It also made it where I could ignore the KAMRFs completely. Once I got the tune to working well with KAMRF learning disabled...

First off confirm this is a GUFx era EEC. It shouldn't matter, but its worth at least confirming what you are working with...and going over some basics that most of us would likely assume is true, but again is worth confirming. For example, when you flip to these tunes, is the ignition switch ON? AS...

From a pure controls standpoint, that NXP chip, using an ARM Cortex M-series processor is most likely perfectly capable of running an engine management microcontroller. However my intentions for an EEC replacement are not to just do controls. My intentions are to host both control logic along with a...

I can see the view count going up on the pictures. Does anybody use these adapters I've mentioned in the previous post? Do they work well?... I've only used TwEECerRT and QH. I can't speak to these. But I don't have any reason to believe they wouldn't work. ...Is the A9L and other EEC4 users dwindl...

So the HSI does capture the time of the event, thus my explanation of the jitter as described above might not actually hold water unless the HSI, itself, is subject to this jitter when interrupts come in fast. As a dedicated "High Speed Input" co-processor, it'd be a pretty lousy one if it was vulne...

I think there's 2 different issues that you are noticing. Lets start with the duplicate values. The way datalogging works is the datalogging device (QH or TwEECer) collects values from the EEC by sniffing the MBus for writes to specific memory addresses and records those values in its own RAM. This ...

1. How do I clear Codes in Binary editor? 2. How can I read any existing code errors from the computer in binary editor? ... As far as I know, you can't. This has been a long standing limitation of datalogging for EEC-IV/V era EECs since the beginning. I suspect it could be done, but would require ...

If all plugs on the same bank are fouled, then this has to be something affecting the entire bank. The only thing I can think of that could do that is a bad HEGO value. Unplug that bank's HEGO, let the EEC "fail" that HEGO and see if the engine controls fine off the working bank's HEGO. If it does, ...

Yeah I was under the impression this was a "build" not putting back what was there. Like I said, I wasn't familiar with your strat and tune.

But now knowing you are working with SD and an otherwise stock engine, I'm with JSA, start looking for typical problems like vacuum leaks.

There's a number of things that will cause over-fuel. If this is 1st crank with this setup, it's not surprising it's going to take some tweaking to get it to run. Unless you are a seasoned tuner that's tuned using your exact MAF and Injectors and thus has high confidence in the numbers entered, it's...

Unless you just already have 4-wire sensors, I'd say stick with 3-wire sensors just to keep things simple. But if you have 4-wires and just need them to work, then you have choices. The first one being tie the sensor ground wires together and tie it to that HEGO ground pin on the EEC. The other opti...

That's interesting information. I don't know that I would've predicted that. I vaguely recall a thread or two from the past suggesting that boosted applications don't like platinum-tipped plugs. And while I found it surprising at the time, I guess it does kinda make sense given CAT converters also t...

Early on, I replaced my fuel pressure regulator with a cheap adjustable FPR (turns out I didn't really need it, but that's not the point). I never had these kinds of issues, however the vast majority of my fuel system is stock up to the engine. My issues with the aftermarket adjustable FPR were with...

The fact that you mention the EEC's ability to control fuel pumps indicates you are not dealing with an older EEC. With older EECs, I would expect the fuel pressure to rise and drop along with manifold pressure, since that's the point of the fuel pressure regulator. However with the newer return-les...

...scaling the tune seemed to be.. impossible? with BE. Fueling would constantly be off across the board even if I had scaled "correctly" and I put that in quotes due to scaling off of Decipha's fueling write-up which I believe to be accurate... I'm not sure what possible benefit TP has over BE as ...

I used TP back before BE existed. And back when the choice was TP or CalEdit for bin-editing, there was no question that TP was the better choice. It simply exposed more aspects of the tune, had correct conversions for things, and was open so when errors were found, it could be fixed by individuals/...

Check your Startup Fuel Row Scaling Function (FN018) and see what kind of times you have in there. Startup fuel enrichment should (technically) end about 45 seconds after startup, but is there any chance your tune has it increased to something near 165? And even with this function being altered, usu...

This is a left-field suggestion that likely isn't the cause, but it's an idea that I had. But my idea is that the Canister Purge valve control is responsible for dumping a bunch of lean air into the system. On both my old 2.9L V6 and the V8, the canister purge air is not going through the MAF. In GU...
