Drive By Wire is a painful upgrade. But SO worth it

If you need anything brother don’t hesitate. I so love this system

“Something is loose” *everything rattling while the car shakes*

at this point, you should just integrate that laptop into the dash

I speak for everyone when I say - we want more street driving footy. Get follow cams. Get drone shots. Interior shots. Even for a test drive like this, would be epic Rob. I already feel like I'm watching Fast and Furious 1 irl.

ECU based pedal tuning is a BIG step but you might want to take a look at the spring load and/or friction of the pedal itself.
You can tune the pedal response up to a point but if your foot is blipping a lightweight, low friction throttle and setting up a kangaroo effect it'll be nearly impossible to tune out fully in a car with such a responsive engine without creating an overly dull throttle response.
I drove a supercharged Arial Atom and was amazed how heavy it the throttle pedal seemed but it makes sense in such a light responsive car for exactly the same reasons.

A bit like the brake issue, you can have great pads, rotors, brake lines calipers and brake balance, but if the master cylinder is loose... its gonna feel weird!

the amount of attention to detail to everything is amazing, anytime there's a dahm video, it's going to be a good day.

Rob: **Puts kill switch in literally the most inconvenient (or should I say, convenient for thieves) location on the car.**
Also Rob: "If you see this car, do not take this."

I am one of those calibrators at a big oem Rob. So many people have no idea how much time we spend on the smallest calibration. I also do the throttle to position curve, so I know the frustration. Keep it up

[arcadiagreen]

The amount of learning you've done to get you to this point makes me glad that I didn't abandon you way back when the 4 rotor was a shell at SEMA

[andrewable]

Transmission sounds so good man. That "clunk" is so satisfying

[ItsJustFeel]

I am so glad you were able to capture the pure emotions of yourself being frustrated by the initial drive by wire! (The flash forward definitely got me to chuckle) If only all of us could just have a glimmer into the future for just a second to know it'll all work out!

[clarky]

Geez, the tuneablity of that fly-by-wire is magnificent.

[anthonyciccariello]

Without the lows the highs are not the highs. I admire your work sir and your fortitude. Keep up the quality content

[KrKrypton]

Now that you have drive by wire with a sequential dog-box you can potentially do auto-blip clutchless down shifts.

0:37 😄 *Rob's opponents noted*

If I was him, I'd keep at least 3 of those keys in different locations throughout the car and on my person.

When I race RC cars we have a setting on our radios called "exponential throttle".. Its basically a setting that can adjust the sensitivity. The speed controller is very similar to your electronic throttle body. Picture a graph of your throttle output where the X axis is the ECU throttle output and the Y axis is the throttle input. If you apply zero adjustment you would see a perfect straight line at a 45 degree angle on the graph. If you apply a positive number it would in effect make initial throttle input more sensitive (very little input to more output). A negative number would do just the opposite. Racers use this feature for better low to mid throttle. I think that "graph" you were adjusting for throttle output is similar to what I am talking about. The curves I see that work well in your case is a parabolic curve starting from 0, 0 (x, y) its very low slope that gradually curves upward almost like a logarithmic curve. This will automatically cure your throttle bouncy feeling. Some racers sometimes have an "S" curve where the very bottom and top of the curve is horizontal in nature. A curve like that will do both better control at very high and low throttle settings so you can have better driveability and better control at the limit to control tire slippage at full boost.

Hope all of this rambling helps. Good luck.

[gavinford]

Wow, drives like OEM by the end of the video. Went from undriveable to perfection.

[krazymann]

Rob, you should see how much test and analysis goes into just getting a modern window switch assembly into a vehicle.

Have to proof the everything AND the manufacturing line. If you move the assy' line to make room for more stuff in the building, you have to re-validate with testing again.

Many teams. But for all the frustrations and hell we put ourselves through, we do it for the end result you showcase here. Having hair left is just a bonus

I dont know if this mentioned in the video just yet, but idle control with ignition is very good to get things smoothly idling, you basically put a "hole" in the ignition timing table where you want it to idle, and put more timing below that rpm. That way the extra timing will push the revs up when idling too low and the ignition cut will stop the idle from running away.

Ignition timing can adjust idle speed part way through an engine rotation (basically between every ignition event) but idle air control can't really do that because air has momentum/inertia, even if the throttle blade closes theres all the air in the intake.

It's mixing computers/technology and internal combustion I love it. I like watching you mess with everything learning.
