HP Tuners for 2005-2015

@HPTuners has been phenomenal. I saw their response and that is what I call customer service. Above and beyond! Toyota fans are some of the most loyal in the world. @HPTuners Thank you for taking care of our friend @arcenik as he is also a great asset to our community.

 

There may be around 20 sets of trd injectors on the market soon after everybody gets their new flow matched injectors.. I am sure somebody on here will be selling theirs for cheap.

 

Could you provide us with some specific instruction on how to scale the stock MAF properly for us boosted guys?

 

Sure, tomorrow I can post a few useful tips

 

@loginfailed found it for me and we tried it out. It saved my ass!

 

You can download the Tundra tune for free, check it out, tweak all the settings, etc. You only are charged the credits when you upload the tune to your ecu.
That's how I got the Tundra tune for us to play with. I got it from a neighbor with a 2010 Tundra.
When you are ready for a larger intake we can help you set it up. A simple copy and paste of one table and the ecu is golden for the Tundra MAF.
Of course the MAF plug needs to be changed as well.

 

Funny you say that, another neighbor may get a Tundra and was asking me this afternoon what options there are for performance.

 

Pops just got a 2019 tundra... Mom has a 2007 4 runner with the single vvti 4.0L. I can probably grab the later pretty easy to see if the 4 runner same drivetrain has a different tune than taco

 

“So what did you do before work this morning?” Oh, went to the gym and then threw a new tune in my truck.

 

Better than coffee!

 

Yeah, I had that too.

 

@JustDSM I wonder if tuning shops have the ability to get universal Pro features to tune with wideband for anyone who brings in their own non-pro hptuner. They would need the pro features to dyno tune as usual with with their own dyno wideband sensor, correct?

 

The MPVI2 module needs a firmware unlock (when you purchase the Pro Features) from HPT to be able to long from the Pro Link expansion cable. If the shop you go too has an MPVI2 with Pro Features enabled, you could add their module to your tune as a slave, and they could flash/datalog with their widebands. Just installing the Pro Link cable into your MPVI2 which does not have the Pro Features enabled will not work unfortunately.

However, if you're doing this stuff on the dyno, they'll be collecting RPM/WBO2 data through the dyno which can then be used. The WB data doesn't necessarily need to be collected natively, just available. though it would exponentially increase the speed at which MAF scaling be done, but general tuning it's perfectly fine to reference an external source for the data.

 

How are those new tranny parameters working for you @loginfailed? Any resources you guys can recommend for getting edumacated on tuning the A750 or just A/T tuning in general? With the exception of having done a fluid flush on mine and briefly watching a valve body upgrade video on YouTube, I know nothing.

 

So the last time I was on a dyno, they used their WB sensor in the tailpipe, however that was just power pulls and not actual tuning.

 

If you're just looking to dial things in a little closer yourself, you could still use their WB setup when you're making your pulls. It'll be useful to make corrections to get your to your desired AFR. Do datalog your runs, so if you have issues or want to spice it up a little, you have data available to make an informed decision about what changes to make and more importantly where!

Have you done any dataloging yet?

 

No datalogging yet. Just got back from vacation. Playing catch-up at work and on tacomaworld...and not in that order

This weekend for sure!

 

I have the 1-2, 2-3 and 3-4 shifts to a point where I like the way it behaves. Still try out little things with the 4-5 and the TCC lock. Basically making a change, then driving it for a few days then repeat. I have the full IPT preformance trans and torque converter, so mine may behave differently than a stock one. You're welcome to try my settings if you want. Mostly, I've just raised some of the shift output RPMs at the lower scale and higher scale of the throttle positions.

I'll put a link up to my tune here in a bit, I'm not on the right laptop at the moment.

 

Awesome. Thanks man but no rush. With your upgrades, it sounds pretty far from what I can expect of my stocker but it would be cool to see what you adjusted and try to learn from it. I mainly want to see if I can tweak parameters to solve some personal gripes (4-5 flare and see if I can get the tranny to hold the current gear a little longer without dropping a gear (or two) when I move my foot into the throttle.

 

I too have the 4-5 flare. I've been able to minimize it considerably, but I'm still trying to figure out how iron it out completely. I had no flare at all on the NA tune with the UCON. As soon as I started running the TRD tune with no UCON is when it started. I think there may also be some other variable in the ECM that @HPTuners has not added yet, such as a load calculation table or something like that.
