A possible compromise is also written into that description...Z_TABOFT. Set that to not be contingent upon WRMEGO thus allowing you to enter FN1360 earlier than CL. But again like the comment says, you'll likely want to increase ECTSTABL to >120deg. Going back to your original comment, you are wanti...

The comments for FN1360 for GUFx are: FN1360 - Stabilized OL Fuel Table This table associates Open Loop fueling to RPM/Load as opposed to ECT/Load, which is what FN1307 associates Open Loop fueling on. When FN1360 is enabled in the tune, it is activated when WRMEGO=1 and FLG_ECTSTABLQ = 1. WRMEGO an...

Most of the tools us that have been here a while used were developed during the Win 2k/XP days so Win8 should be no problem. I used CalEdit/Calcon, TunerPro, and BinaryEditor/EEC Analyzer on a VERY old Dell WinXP machine, then a Toshiba Win7 machine, then my current and very dated HP Omen Win10 mach...

I haven't used that (patch apply feature) in BE for quite some time, probably over 10 years. So I can't say what happened. But it sounds like there might be some bug in BE that Clint can go in, try to reproduce, and fix in a future BE version. While that is the most convenient way to apply those pat...

I failed to also mention those points that if fueling is off during idle, it doesn't matter what your idle parameters are in the tune. Another thing I discovered and didn't mention since I got so focused just on ISC control aspects is that excessive spark can negatively affect idle as well. While th...

All my experience is with GUFx strats. However I suspect other strats are similar. Idle has multiple stages, there's Preposition which is where the ISC gets set when the TPS not at closed throttle. Once the TPS returns closed, the mode transitions to DASPOT which is a decaying of the ISC position fr...

Any time you manipulate your selection of datalog items, re-write the tune even if you haven't made any other changes to the tune itself. It's not obvious, but part of what's being done to the tune in the background is to include some of the values you want to datalog as part of additional "relay" c...

I don't know how A9L2 is setup, but I believe the original A9L would run the engine open loop for a good 1.5-2min before switching over to Closed Loop. During startup (cold or hot), the tune usually runs the engine a bit rich...even richer than normal open loop. But the tune gradually leans out the ...

Most strategies don't rely on MAP or MAF on crank. The tune has a function or table that is hard-coded to fire the injectors a FIXED amount of fuel based on ECT (and possibly voltage). Crank usually doesn't have to be that precise. It just needs to NOT be lean and not be OVERLY rich so much that you...

Even if you don't have a license for EEC Analyser, install it and go to the Cam timing calculator and read the helpfiles about how to use it. There's a LOT of peripheral info about cam timing beyond just using the calculator that I think will answer a lot of your questions.

The adjustable FPR I bought years ago did the same thing. It would bleed pressure off within a few seconds after the fuel pump was off. This created a longer prime-time to get fuel pressure when cranking. I could not turn the key from OFF immediately to CRANK. If I did, then the starter had to be he...

I'm curious what the difference between setting 3 and 4 are from a controls point of view. I ask because my tune is setup for 3 (one switch) however my truck actually has both a clutch switch AND a neutral switch at the transmission suggesting that maybe I should have this set for 4? Logically the t...

Now that the proof of concept has been proven, what's special about this 2.9L? Has it been internally built/modified that makes it stronger than stock? My truck used to be a 2.9L with the 5 speed manual, and while it wasn't wimpy compared the 2.3L, it couldn't compare to the stock Explorer 5.0L I re...

The first thing that's confusing is why you are getting reving limited to 3k. I don't know of a gas engine of the types we'd be talking about here that would need such a low rev limit which makes me think there's something else going on causing revs to be limited. But assuming changes do need to be ...

...I don't think the sensor can really be moved 30 degrees. That would put it right about at the seam between the pan and block where the castings jut out... At least not with that bracket. However you MIGHT be able to fabricate a bracket that holds the sensor "upside-down" such that the bracket is...

Sounds like you have a plan and a reasonable approach. Of course, there will be issues, mostly likely those will be with solving driveability issues with the tune. Those seem to be the worst. The issues most people struggle with initially are idle and return-to-idle because well if you can't get idl...

jsa answered your question. But I suspect you were hoping for a bit more. But more info would need to be known about what EEC catch code you are working with. If your EEC has support, then we'd direct you to that. Some EEC strategies have multiple developers supporting them. But since we don't know ...

WRT to what I mentioned in the 1st post, I was watching the latest Cleetus McFarland episode where they installed a Heliphant (Demon) Hemi into a modified "mini" TRX. And as part of that install, they installed "unlocked" modules from HP Tuners. So it seems my idea of simply replacing hardware witho...

I had multiple main intentions. One big one is for a device that can replace the stock ECM (and probably also TCM) and allow a tuner to tune the engine however he wishes while responding to the rest of the car as though everything is stock INCLUDING appearing stock to an OBD-II connected emissions t...

Just a follow-up after many many months since I first wrote up the document about the EEC Whisperer. It seems the automotive world got far more complex and modular than I realized. When I was thinking of the EEC Whisperer, I was still thinking in terms that there was a "central brain" of sorts that ...

Are there intentions to develop a datalogging replacement for the QH too?

That would be a far more complex endeavor and probably a fool-hearty one given how old the EEC-IV/Vs are now with dwindling demand. But I would certainly applaud and welcome the effort.

It's been a while since I did this to my tune, but whatever numbers I came up with are still working well today. The main thing I remember about setting my tune up for AC were the values I had to use for AC Adder/Subtractor were SUBSTANTIALLY higher (like 10x higher) than the stock numbers in order ...

Yeah you probably should've led with that story to explain what you were actually fighting. Next you are going to tell us you don't have a backup of the original tune that was put in there nor a way to get them. So, now you need to retune the engine. Refer to all the points I made above about gettin...

If the EEC reverted, this would suggest it was running a non-stock tune at one point. The only way it could've done that is for someone to have chipped the EEC. These older EECs were not programmable without the help of external hardware. The hardware can range from a simple tune-holding chip to a f...

Jon responded and said that he has a script that runs to maintain the site certificate without his intervention. It's evidently something that happens frequently enough that he automated it. Well for some reason, that script was failing to run. He looked into it and fixed whatever was causing it to ...

I noticed just now that FireFox is giving me a security warning about the certificate. My guess is it expired and Jon hasn't noticed to renew it. I wouldn't be surprised if Chrome is just out-right preventing you from viewing the site, while FF just warns, but allows it. It's done this before. I'll ...

There's probably a few reasons why that might happen and those reasons might be different based on the strategy you are running too, so if you could, update your profile signature to detail out what strategy and EEC catch code you are running. It would also help if you could post up a datalog of it ...

The only thing I can think of is that the version of EA is not up to date and the license is for a newer version. But if you are a new customer, it isn't likely you would have an old installer. Clint should be contacting you fairly soon and help you get it sorted out. I'm sure it's something simple....

When you have the ability to make changes to the tune, there's no requirement that the MAF be "calibrated" to a specific size injector. What matters most is that the MAF and injectors are correctly sized to the capacity of the engine they will be used with. Regardless of whether the MAF and injector...
