Vitesse Throttle Controller - Wow!
After several weeks of having this piece, I am still amazed at how well it works.


Now, I have been read post after post where people were blown away and now I see why. I read where people said it was like a totally different vehicle but their description still left me with some doubt, so let me describe what it feels like to me. You know the feeling the car gives you when you give it about 2/3 throttle? You get that at about 1/3.
I did this with just a few miles from home. I'm sure tomorrow I'll dial it back a little just for comparison. I can easily say just as others have said, that if you want something to make your car fun....this is it. I really like that I can dial it back instantly too.





I think this unit has enough benefits to make it a better purchase than the others on the market.


There's no 'lag' built in at the gas pedal -- all it is is a rheostat; actual response and throttle body plate opening is controlled by the ECM, beyond the reach of the Vitesse device.
I'm guessing it just changes Gas Pedal signal to simulate a higher value than actual?
30% gas pedal is reported as 50%
50% gas pedal is reported as 70%
70% gas pedal is reported as 90%
Etc
At the end, you're still at 100% max, so maybe it just front-loads the sensitivity to the first 1/2 of the gas pedal travel?
I have a COW Booster/tune and am considering getting this thing, as it is adjustable. The Booster has been the best add on 'mod' I've done.
For me, with the Booster, the throttle will down shift, as well as hold onto a gear longer, as well. Stock my car peddle felt 'mushy' and I had, like others, to get into the push to get the lower gears. It felt like I was starting out in grandma 2nd gear and just pokey. With the Booster it starts in 1st (it started in first stock as well, but shifted to 2nd straight away), and time in gear is longer, and shift down via the peddle is less travel, as well.
Since the Booster is coded into the PCM, I'm thinking this would 'add on' more 'ease'/throttle aggressiveness, even though I don't really want much more aggressiveness, I would still like some, and the ability to be able to self adjust.
Perfect.

My experience is that for those that think there is no delay, you don't know until you know. Trust me. There is a delay. With this unit, you can adjust it to your driving style. They're is about 9 settings and the highest setting is wild wicked, allowing the throttle blade to open fast. You can hear the intake breathing in a lot more air.
This unit also has a Eco mode. Where it limits the throttle body blade. So no matter how hard you step on it, it opens slowly to save on gas. Overall, it is a great mod and at a great price.

The Best of Corvette for Corvette Enthusiasts





If he can sell sell more on lower cost forums, then he may have enough left in the budget to advertise here. Low volume and high costs are why the Corvette tax exists.

Both harnesses connected
No power on the controller with all connected
With car in the On position, this is the message on the display
I would disconnect everything, run the vehicle some as normal, then follow the Vitesse set up EXACTLY. If still issues I would disconnect the battery for a couple minutes, then drive, then try again with install.
