I have never written the re-calibration file for any car or truck. HOWEVER, I have done multiple on motorcycles. Most of the bikes I have done are drive by wire just like trucks/cars. I try to explain this to anyone who buys the pedal commander products. These products cannot fool the ECU into opening the throttle any more than what the ECU allows. PERIOD. There are multiple if not hundreds of throttle control tables in an ECU that are used in various modes. The ECU reverts to many many different tables when in normal driving, traction control, torque management stages, etc. NO matter what the throttle pedal "commands (% torque requested)", it ain't gonna do anything more than what the currently accessed table permits/allows. PERIOD. So when u use a pedal commander. It will ramp the 0 - 5v command voltage more aggressively effecting is "rate" of opening, but the throttle will position ONLY at where the currently accessed throttle table allows. It does not do anything more.
This is probably what the Pulsar does in regards to throttle. It cant possibly do anything more. Now that Im thinking about it, if it can do anything, it would have to have the ability to put the ECU into a mode were it can select a more aggressive ECU TABLE than the previous mode. If that is possible.
So, I changed my mind on a Pulsar. Even though I still believe its a decent product for the money. I am probably going with Livernios. IF Im going to spend 600 for a piggy back, I may just go 1000 for a replacement ECU, THAT WILL ACTUALLY OPEN the throttle plate way more aggressive and at a higher percentage, adjust fuel, add timing, REMOVE or REDUCE TORQUE MANAGEMENT and more. You get way more.
I think code P1400 or something is the code the dealers look for. (unauthorized non OEM vehicle calibration detected) Im told it is stored in the body computer and NOT the PCM itself. Livernios has assured me they don't trip that code. I go to the dealer, I just swap the PCM's out. This is exactly what I did in my 2019 Wrangler. So, Now I wait for my truck to be delivered. Get the PCM part number, and find a new replacement or a used one to clone.
