What he can see in 5 minutes takes me hours to learn. His trans tune is worth it alone! (I know your manual) I know the fundamentals, but it is worth it to pay him. Now with all that being said I still use Shane Hinds to tune my car. It’s the hack method because I don’t have the HPT Pro version to run it into HPT direct. I wire the NB output into the ECM for closed loop and the WB output into the AC pressure port. There are a bunch of widebands on the market. I pull one of them off my motorcycle and install in place of the front O2 sensor. Then when you are ready to get WOT tuned install a wideband setup. You can leave your stock O2s in to get idle, cruise, and drivability dialed in. You can pay per credit or buy a package deal. You need the HP Tuners and then credits to tune the ECM. I have confirmed the fuses related to the npp system are in place.Correct. The computer closes them and reopens based on certain parameters. The default position in the ZL1 are open. But the tuner has not responded to my question as to whether or not he disabled the valves. The following are the 5 parameters I am interested in editing along with their reported values in the last scan.Įxhaust Valve Status = Disabled Exhaust Valve Enabled = Yes Exhaust Valve Start Rumble = Yes Exhaust Valve Open Threshold = 0% Exhaust Valve Close Threshold = 0% I have set the editor to show advanced parameters and I also completed the training offered by HPTuners that was supposed to unlock some parameters.ĭo I need to buy some other particular credits? However those parameters do not appear anywhere in the editor. I recently borrowed an MPVI2 to troubleshoot problems with the dual/mode exhaust on my 2012 ZL1.ĭuring a scan, I added 5 channels related to the exhaust valve report data.
