I installed an injen throttle controller and if i turn it up or down, it wont let my rpms exceed 2500 Mechanic's Assistant: What is the make/model/year of your car? 2013 hyundai elantra coupe Mechanic's Assistant: Are you fixing your Elantra Coupe yourself? What have you tried so far? Yes, and i have contacted the manufacturer, ive tried clearing the codes with an OBD scanner, and checked all wiring harness connections both with the OEM and aftermarket Mechanic's Assistant: Have you checked all the fuses? Do you have a wiring diagram? Yes all fuses are ok. and no, it was a pre made harness, direct plug and play

Hello, Welcome to Just Answer My name is \*\*\*\*\* \*\*\*\*\* I've been an automotive engineer since 1996 and together we're going to solve this issue. I would say the new throttle controller has offset the pedal position sensor output so it now falls into the 'failsafe' level of operation for opening the throttle as this function is so safety critical it is very difficult to modify anything by using a 'bolt on', normally any throttle pedal reshaping has to be done within the ECM Do injen have successful test data from other users with the same vehicle ? I'm assuming when you return the car to stock the issue goes away ? do you have a scan tool that you can read the fault code with when you have this issue ?
