JDMlyfestyle

My car has been running perfect until yesterday. The idle got really jumpy and stayed at 1500 and it would bounce between 1k and 2k. today i started the car and the idle is fine. But i noticed My Vtec isnt Engaging at 56 anymore its going at 62 now. and i have no idea. why. the only thing i could think of is that i added a Infinity bass link to my car a couple days ago. could that be the problem.. Please i need Help

since you think it's the ecu. Have you tried a known good one just as a process of elimination?
