at 10 psi, normally you would need a minimum of 4.5" intake pipe to avoid maxing out MAF.
I don't see MAF (Voltage) in the channels
I like the spark tables. Conservative at peak torque area.
I...
Ffv have an internal in-tank regulator that restricts fuel at wot. This has to be disabled.
you could try bench writing using Toyota ECU flasher.
I once asked HPtuners, and they said it may work using MPVI2 but you risk bricking your ECU.
Speaking from experience, you don't really...
I dont think HPtuners is capable of doing the above yet
Absolutely!
Hey Evans, please update.
Any luck in getting the Knock PID logged?
Also we tried to increase the RPM limit without luck..... :(
Thanks a lot @SlownNstock
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...
Thanks a million man, it surely shifts a lot better.
1/4 mile improved by 0.3s by only tweaking the Ignition Efficiency table.
Gonna install Water Methanol injection next week. Then I will try...
Hey @JustDSM, do you have the same spreadsheet for 6 shifts Tundra ?
would you shed light on how to use the spreadsheet? Tundra Gear ration is 4.3
Thanks @SlowNStock. I managed to amend the shift points, which are honestly not my ultimate goal.
1-2 shift is remarkably better after making it to shift earlier.
However 2-3 is still not...
I have exactly the same truck with the same setup and would be very much interested to know your findings, especially with transmission tuning.
Kindly check post 39:

@SlowNStock and rest,
Been trying to tune a 2016 FFV supercharged Tundra. We managed to get it almost tuned, but the truck shifts like crap specifically 2-3 shift. I am trying to force shifting at...
Found the offset data here:

The truck runs great at...
i have upgraded the injectors to 650cc and reduced the injector constant value to 0.063.
Fuel pump pressure is set at 60psi.
The truck idle at 20% lean. I have tried scaling the MAF without...
I am trying to figure out how size of injectors affect the injector constant value. I am told that stock tundras utilise 390cc injectors. So lets say that I decide to upgrade the injectors to 650cc,...
Thanks a lot for your generous info, very much appreciated.
My Learn Init was at 19 degrees, I dropped it down to 15 degrees. I will put it back to 19 and work from there.
I will also disable...
So 0 KFB is > -3
I have reached 28 degrees and still got 0 KFB. Does it mean that I can still add more advance timing?
I am surely missing something here.
One thing I noticed is that AFR went...
Thanks for the info.
On a side note, hptuners support could not add the torque management tables currently. However after tweaking the desired throttle angle tables, trans shifts are way smoother!...
I realised that tuners change the initial value for Knock learn from 19 to 15 degrees or lower.
The default values for both Init and Max knock learn is 19.
May I ask why do we need to do so...
I could not find Torque Management under Trans
Thanks mate. You are the best!!!!
Will try these changes later today.
You would not believe how much tuners charge us over here.....really appreciate it.
my 5-6 shift is a bit aggressive. What would you try to make it a bit smoother? Valve body is stock.
