DIY fake exhaust tone

[Progeny2021]

I am looking to start a project to add a fake exhaust tone to my truck. I know … I can’t believe I am actually doing this as a purist gearhead myself, yet audis and maserattis have it too.

There is nothing I can do to my small diesel as it has a cat and a DPF with an aftermarket exhaust that would still be compliant in Europe.

I can buy off the shelf systems like Maxhaust that connect to the OBD port to read the RPM, yet I want to build one myself with an arduino, an amplifier and a ported box speaker enclosure.

I need a simple way to read RPM without CAN decoding or … to read the throttle, and I am looking for ideas.

The pedal is a potentiometer, I guess I can read the voltage or resistance, either would work. Any thoughts in this?

The fake noise will be outside, not inside.

Here ya go...not many Ladas sound like this...

May be there should be a law against stupid stuff. I would not brag about making money making stupid stuff. Another negative result of over population.

This post is so idiotic that normally I would not reply to it. This is my own project and I’ve said from the start it will be open source. Learn to read before you pour all the accumulated hate you moron!

Anyway, I’ll stop posting here. Probably get banned too, I simply cannot understand why so many of you are hating this, just because I’ve said “fake”. If I would have posted a sound-clip saying this is an aftermarket exhaust, probably it would have been different. Many colleagues have upgraded to magnaflows and borlas just for the sound, couse there is no performance gain or marginal at best. Yet, that is ok. Then a guy comes along with a bit of skill trying to do something else in the new world of electric sounds, trying to keep a bit of the past.
