First, I just rescaled the table as shown. I also created a couple tables with Fuel Mass on the y-axis, one measuring error between commanded AFR and wideband AFR and the other showing LTFT.
68215...
Regarding the injectors. You might have better luck if you rescale the tables. It makes no sense that just three datapoints define basically the entire operating range of the engine. Take a look at...
Still tweaking the injector PW. I think I've been chasing the fuel trims around too much, so I'm going to let it ride for awhile and then hopefully make one final tweak. No big deal.
For...
I took the leap and tried it out. HPTuners won't let you add data points so you just have the 14 points to work with. I kept the first and last data points and a few in-between. I made an excel...
At idle, cyl 1 fuel mass is hovering around 10 mg. WOT nearing redline and it's peaking around 85 mg. This is what I'm seeing consistently in my logs, and the numbers make sense based on the Pratio,...
Hey, sorry for the delayed response. It was a 2bar MAP included with the Procharger kit.
Following up on this comment. I noticed in my custom tune that the tuner dropped the OEM threshold from I think 3.4V to 3.0V so power enrichment starts sooner. What could be some of the reasons for...
Cool. I think I will start there then. This project is a learning exercise more than anything. I might as well take the time to learn how all of the different tables affect the actual performance.
Mods are cold air intake, ported throttle body, long tubes, high flow cats, and corsa exhaust. I have seen changes by modifying the commanded FA, but when I'm commanding 11.5, I'm actually seeing...
It's a 2012 Charger SRT, and I have the NN turned on. This is the first time I've tuned anything so I'm figuring things out as I go.
Sounds like step 1 then is recalibrating injpw vs fuel mass so...
Here's my tune. 2012 Charger SRT with P1SC Procharger.
Open up your list of parameters. There will be an option for Serial and LC-2. Add that to your list of recorded parameters and the software does the rest. I've noticed that you need to plug in your...
Trying to understand how this works. The FA Power Enrich vs Aircharge vs RPM table represents the desired air/fuel mixture at a given cylinder aircharge and engine RPM. The ECM takes these values and...
Here's my first crack at a correcting for the voltage offset. I have a custom math that calculates percent difference between analog and digital. This graph shows digital AFR along the x axis.
...
What size cap are we talking about? I've noticed during periods of rapid transition (say dumping the throttle after a WOT pull), the analog signal lags and looks more like a staircase than a smooth...
I'm interested. I added a custom math parameter to contantly calculate "error", but I have a feeling this may not be the way to go as I'm guessing there's some level of latency between the digital...
Good to know. I always buy Top Tier gas (92 octane around here) and run an injector cleaner through every 6 months or so. I feel better knowing it's common to reduce the sensitivity, but 56% seemed...
This particular tune was a custom CMR tune and tweaked on a dyno (tune attached for reference). It's three years old at this point, but I'm not sure if that'd make any difference. The computer pulls...
I guess as a follow-up to this... Are the offsets typically even across the range or do they follow a curve? In other words, is my 0.1V offset likely to be constant across the full range (0V = 0.1V...
Don't mind me then. Just a newbie making obvious statements. :hi:
I'm using the MVPI Pro interface, and I have an Innovate LC-2 tied into it using its 5V analog output. The innovate controller is configured to output 4V while the sensor warms up and before it...
Logically, what you're saying makes sense. More fuel should be required for a more free-flowing setup. In comparing the OEM tune to my CMR tune though, the tuner actually removed fuel. Take a look at...
I've got a 2012 Charger Super Bee with a full suite of bolt-ons (cold air intake, ported throttle body, long tube headers, high-flow cats, and Corsa exhaust. I had a Diablo CMR tune done for it, and...
