Build Meet "Billy"

[pappy]

I also upgraded my controller from a 30A PWM to a 40A MPPT.

As of yesterday the solar panel is NLA. Glad i bought when I did.

When you think... this will be enough..., double it and it still will fall short - powerwise that is.

Dyno tune day. Some of you met @CAMTuning at the breakfast. He has a business where he mostly custom tunes Subaru, but has branched out recently into the Gen4 Tacoma. Saturday, after the breakfast, he came over and did a minor tune on Billy. Today, he did a full dyno tune. He increased the factory HP from 235whp to 274whp, and torque from 291ftb to 336ftlb. Look at how jagged the factory torque curve is, and how he not only raised it, but smoothened it out. I was pleased with the minor tune he did on Saturday. I was very impressed coming home after the dyno tune.

So what are the negative implications of this tune? Reduced fuel economy? What will wear out faster (Besides tires)?

Fueling is way safer than stock. Higher rpm can cause faster wear if you’re on it all the time. The other implication is extra wrinkles along the side of the face from excessive smiling.

Considering the advanced age of the owner, I doubt the extra wrinkles is a concern. I'd be willing to gain some extra wrinkles if I could increase hp and torque on my 26 year old 4.7L in my '99 LC.

Cam can correct me here, but I think he said Toyota tuned the engine to run lean, which doesn't sound like a good idea with a turbo. From my memory, running lean is harder on the engine than running rich. One change Cam made that I really approve of was raising the red line. On the manual tranny trucks the redline is around 5200rpm. That redline was stupid and frustrating since the rpm was rev limited. On the automatic tranny trucks the redline is 6000+rpm. Cam raised my redline to the automatic spec. The engines are the same auto vs manual, so it doesn't make any sense to have different redlines.

This time next week I'll have an answer if the tune changed the fuel economy.

this is great info, thx for explaining it in this manner.

I'm curious, how does a tuner tune Toyota ECUs since they're supposedly "locked" down, unlike the GM PCMs.

Voodoo is the only answer I have.

100% Voodoo.

They are locked down, but have been RE'd by Cobb Tuning. I've been a Cobb Protuner for many, many years, and when support was going to come out for these trucks, I bought one to do my own R&D on. We have full access to load/torque control including boost control, fueling, variable valve timing, spark advance, etc.

Ya, I'll just stick with my answer ... voodoo, black magic, wizardry, witchcraft, alien science.

Don’t know about the last one, heard it’s rather invasive…..

Is he able to target the "rev hang", as in, get rid of it?
I had to install a device in my corolla to rid of the rev hang. New cars and their emissions programming have really ruined the experience
of a manual transmission, especially if you are used to the older throttle cable equipped toyota manuals.

Rev hang elimination on manual transmission

I've never liked the way my 2010 Corolla S 5sp shifts compared to my older manuals. If you have driven manual from the past before drive by wire you did not have to deal with "rev hang". Rev hang is programmed into the ECU by car manufactures to decrease emissions. What this means is that when...

You mean rev hang like the old school dash pot would do? Keep the rpms up between shifts? On my truck there isn't any hang between shifts. It does have a button called iMT. If I hit the button, which I always do, it rev matches the shift to the truck speed. It's not the default setting. I happen to like this feature.

Yep! Rpm artificially kept high after letting off the gas.
Rev match is nice…had it on the FRS and loved it

Yes, MPG went down quite a bit.

it's not due to stomping the gas pedal with a smile on your face?

 

[pappy]

It has everything, well, mostly everything, to do with that. It's actually fun to drive ... for a truck/camper. I mean, if I had a chance to pass, any reason to pass, I hit the gas and watched the speedo, tach, and boost gauge climb.
