Moates Quarterhorse BE Questions
I apologize if this topic has come up often. I recently bought a book on tuning the Quarterhorse using Binary Editor and have been watching all the YouTube content I could find. However, I quickly encountered an issue: the KAMRF 1 and 2 values are always at 1.0, and my AFR is stuck at 22.4. Surprisingly, the car runs and idles quite well, though it's running very rich.
Upon seeing numerous error codes, I realized there was a problem. I'll start addressing these issues, though some, like EGR and smog-related errors, are no longer relevant.
I've owned the car for 22 years, and I made some mistakes with it as a kid. It's a 347 stroker with 24-lb injectors (Ford Performance) of unknown specs, a larger MAF with unknown values, Performer RPM 2, Victor Jr. cylinder heads, and an unknown camshaft (suggested by CHP years ago).
What steps should I take first besides addressing the error codes? Are there still tuners available? Should I consider scrapping this setup and switching to a Terminator X system?

Re: Moates Quarterhorse BE Questions
Thats a pretty basic setup, should not be too difficult to dial in.
Its the unknown maf thats going to be the hardest to dial in. It probably goes into closed loop but fueling is too far off to stay in closed loop.
Im going to assume you see 22 afr commanded.Either the maf transfer or injector slopes (or both) need adjustment.

How do I find the slope profiles for the injectors?

Re: Moates Quarterhorse BE Questions
Under "constants/scalers", injector high slope, injector low slope. Set both to 24 for now. (Stock are 19hi26low). There rest of the injector related functions are more for fine tuning.

Re: Moates Quarterhorse BE Questions
Should I buy a new MAF calibrated for 24-lb injectors, or should I use the EEC analyzer once I obtain the license? I'm not sure it matters what a new MAF is programmed to as long as EEC analyzer can get the correct curve for the fuel ratio?
Thanks again!

Re: Moates Quarterhorse BE Questions
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 injectors are matched or not, enter the MAF curve and the injector parameters into the tune and now you have "matched" them yourself.

Re: Moates Quarterhorse BE Questions
I began making progress with MAF tuning by making small adjustments, then taking the car out for a drive while monitoring the wideband sensor. Suddenly, it switched to open loop, started running poorly, and became very lean. Does anyone know why it would suddenly switch to open loop?

Re: Moates Quarterhorse BE Questions
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 happening. Assuming it is a GUFB (or similar strat), I'd want to see both the tune and the datalog with the following payload items, at a minimum, logged:

Re: Moates Quarterhorse BE Questions
I don't have the log showing the moment it switched, but this link will take you to a few data logs. Additionally, my KAMRF 1 and 2 are not learning, and I don't know why.

Re: Moates Quarterhorse BE Questions
I've started reading the Moates Quarterhorse book and am currently focusing on adjusting the MAF curve in open loop. I'll provide updates as I progress, but I believe this is a strong initial step in tuning and refining the car.

Re: Moates Quarterhorse BE Questions
Most likely because your fueling is way off. It needs to stay in closed loop long enough for KAMRF learning to take place. When fueling is far off, the eec keeps going back into open loop and never learns. And engine temp needs to above 170F and below 226F (stock values) for adaptive to learn.Swhitney wrote: ↑Tue Jun 18, 2024 2:34 pm I don't have the log showing the moment it switched, but this link will take you to a few data logs.

Re: Moates Quarterhorse BE Questions
hey there... just wondering if those temps are the norm for various ecus..|
im chasing an issue where im not getting adaptive LTFT .. id like to know what the temp setting is but ive not got it in my def..
what catch code bin are you using and do you know the memory location for those temp values?

Re: Moates Quarterhorse BE Questions
A9P using TunerPro. (aka GUFx)
AFECT1 is minimum ECT,
AFECT2 is max ECT.
What is short term doing?

Re: Moates Quarterhorse BE Questions
Maybe you need to clear kamrf's as soon as the vehicle is started..
Go to find and put kamrf. Pick the upper one then go to Dash 1 start the vehicle start a logfile hit tuner hit clear kamrfs hit update then switch back to normal and hit update again within 5 seconds and you should be learning again..
If not somethings too far out of whack so what I did to see how far was to raise the kamrf learning to 24% by changing the values to 1.25 and .750.

When I did it I found that my adaptives were responding and were -22 and -23% out of whack so I changed my highslope by raising it 5 points which brought it down to -11% then I forced Open loop and found out that I needed to tweak the injector timing for my camshafts valve events and that cleaned up the huge offset alot more ..
After I got the fueling dialed in to within 4% I did a MAF autotune.....

I think I got the tune looking and driving as smooth as it ever can be...

Having a fuelpump thats rated above stock and setting the fuelpressure above 39 with vac line unplugged will cause issues too..
When you go to hardware settings tab does the wideband you are using popup on the screen?

As I remember , when I got my QH it came ready for an Innovate brand wideband but I told the person I ordered the QH from brand new I already bought an AEM and because of the issue it caused problems for my wideband readings until I was sent a dongle update..
Good Luck
