HP Tuners for 2005-2015

what I meant was you can upgrade later without penalty of not buying originally. Not free upgrade, you can just change your mind later and it won’t cost you more for not doing it initially

 

Ah okay, thank you for the clarification.

 

Get it! Do it! Love it all over again!

 

Heck yeah man! I would do it all over again too for simply throttle pedal mapping and transmission changes alone. Throw your awesome engine tune on top of that and there is NO reason to go back to stock!

 

From a component protection (cats) perspective. What kinda AFR should one shoot for under WOT loads? 11.5ish:1 ?

 

Depends on RPM/Load. But that's a fair target value for any meaningful load. N/A could go leaner.

 

I'd say 12-12.5 at wot n/a, that's how my race truck is set up for

 

Thats what I figured. Id rather be on the safe side. But I did some looking in my logs and compared to stock. With maf calibrations making absolute load numbers much more accurate (and greater), this has effected where im at in my fueling maps . So while component protection maps were leaner than stock, because abs load numbers went up the net AFR is essentially the same haha. Before maf calibrations i was looking at desired afr's around the 11.5ish mark.

I should mention totally stock exhaust manifolds

 

On a MTB ride, but just wanted to mention you should use Air Load instead of absolute or calculated load (SAE). They’re close, but..

It is the load value the ECU uses for the load axis.

 

Yeah I log both but pretty much reference Air Load in my stuffs. (i do mix up calling them the same) but good catch.

 

12-12.5 for N/A is a great all around safe range for these engines.

 

Cool deal thanks guys for the reassurance!

 

On a side note, do tacoma's have a bunch of torque management programmed into their computers like gm vehicles?

 

There is torque management, yes. And it will limit the output for even basic bolt-ons. One of the reasons why everyone thinks you can't make any power from bolt-ons with these trucks. That's just not true! Though, admittedly you're not bolting on 20-30hp intakes and exhausts.

In my tunes, it's calibrated to match the modifications. I do not "disable it" by maxing it out in my tunes.

 

On the auto side there is definitely torque management during shifting (drastic retard on timing and huge increase in fueling). I have not messed with reducing timing retard as whelp, im not trying to win any races so lets keep the trans happy.

 

OK.... I can not wrap my head around commanded fueling (desired lambda) and how its calculated, hear me out.

PE is pretty easy to see, nice flat line at what i have set of a multiplier of 1.195 (so desired lambda of .837 or 12.217:1 if using 14.6 as stoich).

Looks like there is a delay timer before component protection takes place and when it kicks in it follows what I have setup in my EQ Base graph pretty good (when not under PE throttle inputs)


BUT when multiple things I think should be effecting the desired AFR in an additive manor im not seeing numbers that i would expect, that is higher throttle to be in PE and higher load / rpm so component protection is also adding fuel adding on top of each other. Its almost like in this situation the logic is to take the greater of the two values, which if thats the case it ends up following my EQ Base map pretty closely.

 

I dont know that there is a specific "timer" but you are correct that it does behave that way. It's about ~3seconds from all the observations I've made.

The PE and COT maps are not additive. As long as the triggers are met for the activation of either, the one with the higher EQ value will take precedence. If I'm understanding you correctly, you're thinking they are additive in the sense that the PE table having say 1.5, an the COT map having say 1.5 would mean a total correction of 3.0? If so, they don't work that way, and instead will apply only 1.5 of correction.

 

Pretty sure ALL vehicles with auto transmissions have it BUT I don’t think there is TM on downshifts (which is why WOT downshifts are hard on your tranny). Maybe not even any TM from 4-5.
If it wasn’t there it’d be like power shifting a manual all the time. I know, not a perfect comparison because mechanical clutch but you get it.

Edit: if you were to install the IPT shift kit then you could probably get away with reduced TM without compromising the trans too much

 

I don’t get it. Are you saying there’s torque management all the time and not just between certain shifts?

 

There is TM on the downshift.
