HP Tuners for 2005-2015

Like stated we can definitely change the overall downshift curves so that the downshifts will occur quicker into throttle inputs at higher speeds.

But the functions like auto downshift due to riding the brakes on a downhill, or hanging to gears on an uphill (AI functions) is not something that we have tuneability for.


Id be happy to work with you on a "sportier" downshift curve over the v12 that we can put into your tune! shoot me a PM with your latest tune and we can go from there.

 

Yes, yours has v11 or v12 in it, I believe I did update it to 12 but I’d have to check

 

@12TRDTacoma Confirmed, V12 with some pressure tweaks from previous work we've done.

 

Awesome brotha. Thank you! That would explain the feeling like it wants to "go" more now that I've gotten the more updated 3.5 intake version of the tune. I got my laptop hot and reasy to go when you are for the next tune file.

 

From my most recent log, I am up from the previous 42.83 lbs/ min or 341.7 gm/ sec at WOT that 3" intake configurations allow. I am quite pleased with the added change which the 3.5 intake allows.



Yes throttle % max out is at 81.2.

 

FYI, if you use "Accelerator Pedal Position" you will get a proper 0-100% reading.

 

Oh I just use the basic layout which was sent to me by Justin. I don't really monkey with the tables and when it comes to toying with this stuff I am a total amateur. Hahaha. I am not super PC saavy enough to know how to change things around like that.

 

So VCM Scanner you have channels you record (the ones that Justin has sent you) and then have graphs, gauges, chart vs time that are based on those channels that are being recorded.

If you would like some cool gauges / graphs / charts vs time let me know and I can send you my setup.

 

Any one with a bench harness actually put resistors in there canhi canlo circuit?

 

120ohm

 

Yeah i stole some out if a cat haul truck.
Nice molded deutch plug jobbys. But did u actually put them in? Ive made bench harness’s for caterpiller stuff with straight twin core from the service tool the the ecu and no dramas

 

Is there a resistor in the taco schematic?

 

Shoot them over my way! I like observing the datalog info for personal reference just so I can see how clean, or dirty I am running, and if something is off that a normal scanner doesn't pick up.

 

I will take some as well please.

 

There is. The location depends on the year. 2005 for example has the resistors [they use a low pass filter (capacitor to ground) to remove noise] one on hi and the other on low terminating to the capacitor as part of specific connector. 2015 on the other hand has that exact setup as part of the cluster.

 

I'd imagine it would work without them, but I went ahead and put them in there.

 

You ran them through to a ground or buffer between hi and lo like i guess a traditional Canbus circuit is

 

I didn't ground them. They do in the OEM harness though.

 

Mk cheers. Any one thats interested
The caterpillar Pn for these is

174-3016
and would be about $10usd from your local dealership

 

Hey folks.
I have a set of 550cc flow matched injectors for sale.
Brand new.
Don't need them. Will throw in a HPTuners tune with them if you want them. (If you already have Hp tuners cable and credits).

$540 new, will take a decent offer on them.
