OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

Curious if it was actually a defective fuel pump or the fuel pump controller

 

I don't know if he is actually prototyping with an Arduino but it's what I would do. It's an exciting time we live in where you can CNC a PCB on a $100 CNC router. or better yet, get PCBs professionally made for less than $0.10 each. If you haven't seen this before, here is the ArduinoOBD source code. https://github.com/stanleyhuangyc/ArduinoOBD

 

Yep. It's amazing the amount of computing power and I/O you can get in the size of a stick of gum, for about the same price!

Also, that's a cool project. I may have to play with that.

 

Would you rather see them handle these things like other manufacturers?
Wrangler frames rust faster than Tacoma frames...

 

Where do we go to check for recalls?

I have a 2018. Nothing is listed yet

 

Thanks, yup mine is on the list

 

Yes prototyping on arduino software using an high powered Atmel MCU.
Prototyping on arduino IDE makes it possible to do this so quickly.
Not using a cheapo breakout board or UNO or any of that.
Then once complete I'll write it out in C proper.

Accurately reading the signal the ECU sends out is actually rather tricky.

Let's see if you can figure it out! . I'm not going to post the secrets, but here's a hint.

What type if signal is it if you need to to measure 2 things, add them together and divide over a set time to calculate your time period?

 

Easy. That’s the signal a woman gives you when you ask her where she wants to eat!

 

That and?

 

That and If you figure this crap out in a simple formula I’ll send you $500 a month for rest of your life!

 

On time, off time, period. PWM of some kind I would assume?

 

PWM can be calculated by the amount of time measured the signal is high alone.
Something else requires the time the signal is high, then the signal is low, then back to high over a time period.

 

Dookie cycle

 

Duty cycle and Frequency define PWM. Or the other way around. They're all related, but in the arduino world you would measure duty cycle by doing what Mat said On time vs off time. Frequency can be done by counting # of rising edges over time.

 

Above my pay grade.

 

They're not doing something fucky like with RC airplane PCM radios are they?

 

You’re not talking about VFD are you?

 

I have no idea what u just said haha

 

The formula is simple, just divide by 0.
