Discussion and questions related to the course EFI Tuning Fundamentals
New to HP tuners and I have a question about the fuel trims. I'm running a p01 pcm in my turbo Silverado and the previous tuner disabled the long term fuel trims, is there any reason behind this? I question this because I've already found other issues with his work like fuel injector data that wasn't even close to the data given by the company. Thank you for any input!
I can understand disabling as a temporary/troubleshooting measure, but I wouldn't hand that over to a customer as a long term solution. It basically means he couldn't get the tune dialed in or there was something disturbing the fuel trims that he couldn't figure out.
Okay thank you! Definitely something I need to sort out.
