2009 Tundra Stock 5.7 non-flex
2009 Tundra Stock 5.7 non-flex
Hope to get a good result.
Wanted to share with you the latest datalog I have got for my supercharged tundra. Actually the query pertains to the injectors duty cycle reaching 97% at AFR 11 (WOT). I will try to trim some fuel to reduce the DC but is it time to upgrade the 650cc injectors? Any thoughts are welcome.
My engine is not supported, so I am taking matters into my own hands. I see some great knowledge on this forum, so I am here seeking some beneficial insight. Can anyone comment on these original ignition maps (see the attached image)? They are from a 2007 Camry ECU, 3.5-liter V6, dual vvti. They are found consecutively in the binary. Is there any similarity to maps in your HPTuners definitions for your engines? Can you identify the function/purpose of the individual maps? I am working on releasing some open-source (free) definitions and would like to make them as useful as possible. In case you are wondering the tools I use for analysis are WinOLS and TunerPro. For re-flash I use Tactrix Openport 2.0 with PCMflash.

Note: Could not fit them all in one screenshot so I split it in two.
PS. For reference, these are the dual VVT maps, target angle, exhaust and intake.

Can you attach the source file you're working with?
I will try to sign you some cards.
You can write me a Private Message.
Thank you for offering to help. This is the binary file.

Sending you a pm.
I am interested, in particular, if it is the same strategy with the same maps outlined in Post #10 of this thread.
https://forum.hptuners.com/showthrea...l=1#post598929
Qualitatively the ignition maps I have shown from my ECU seem to correspond to the ignition maps listed in that post. Can I get confirmation maybe based on what you see in your tuning suite?
By the way, I have also decoded the PID's for the knock learn and knock feedback - just used simple can sniffer and Techstream to do that.
PID 21 B2.
Knock Learn = (A * 256 + B) /32 - 64,
Knock Feedback = (D - 256)/32
So anyone with Torque Pro should be able to monitor and log these.

Disregard the timing strategy in that post, after doing more detailed logs, it's not correct - I haven't had a chance to follow up on it yet.
While leaning out will give you a little more injector headroom, at a glance, more fuel pressure or a larger injector would be a wise choice. Note how logged AFR goes leaner proportional to engine RPM here: Fueling.PNG
Assuming a good airflow model, injector data, boost-referenced FPR, etc., that trend is indicative of losing fueling authority (injected fuel mass isn't increasing linearly with increased pulse width) - even with a conservative target, it's not desirable to be operating in a range where actual AFR cannot match commanded AFR.
FWIW someone else who claims to know the Toyota ignition strategy gave me this vague explanation:
It takes the most retarded timing value (except the two tables you have which are modifiers for cold ECT)
Then it takes into account all compensation values, multiplies by KCLV, reduces by KR value,
and there is your base ignition.
Then if it is D4-S based, it will select table based on if port injection is active or not.
The entire ignition strategy is well defined in the tech manuals and explains exactly how ignition is derived.
does anyone have injector data for the 2011 TRD injectors? Hp tuners cannot confirm if the file I have is for the TRD or ijenot, and I cannot find any injector data online

@ViktorG i see you found it! There is def some good info on here for your truck!
Here is the stock file that I managed to pull from a client's vehicle that came in for tuning.
I have been leery about making changes to this calibration as when I write the flash it only gives me the Write Entire option on the VCM Editor 4.6.4 and
I do not want to brick the ecu.
Do you guys only have that option when you go to write a file on a Tundra?
Hey korbians,
Is that file "oem" tundra your 2016SC FFV?
I have a 2016 FFV that ive supercharged and they are telling me (HPT) that they can only start me with a base n/a file. I need to find a SC 16' file or at least know where to modify the stock file to get it running the SC safely.
Are we able to easily import tables from a differnt year truck? Can i take a 2012 SC table(ie: maf and injector tables) and port it over to my 2016 file easily with HPT?

Yes, you can easily copy tables over to your NA tune and overwrite them. There will be more to it than MAF and injector tables though if you want it to run like it is supposed to. Shift points, rev limiter, speed limiter, torque management etc. tables will be all different.
But in the end, it shouldn't take very long to create a working tune for your SC by copying everything over.

I was wondering the same as grannysshifting?
from what i remember I had the file from when the calibration was written to my truck from factory the dealer, then just saved it as an .hpt file, ive been out of it for a while now due to a human S/C now crawling around the house. so if anyone else can shed light on this.
