so the e throttle thing has been a sticky point for a lot of "passionate" drivers. The motor has such little delay when configured properly, you CAN NOT tell the difference.
The problem is that Nissan builds in a delay between the pedal and throttle plate. I eliminate all that and do not let the motor prematurely start closing like they do from the factory to lessen the harshness of the rev limiter. The throttle response with my e-pedal mods are the first things all my retune customers notice.

Basically what happens is that if you turn on the Osiris logger to full tilt and it samples at .1s intervals, you can see a good bit of lag between your foot (throttle %) and throttle plate %. After the mods, the lag is so negligeble, it really looks like you are connected from the pedal to the throttle plate mechanically.

For the super purists I guess, I could setup a quadruple TPS switch (yes there are 4 of them) between the pedal and TB. and run it that way....

but why do that, when you can source a e-pedal for $50 from any yard and the money I charge for the harness job includes wiring it in... and the $450 includes a tune / e pedal mod / security / code removal.
