how do you access "the codes" on a 2004 Z06. I have a check engine light on now and curious why. Installed a BlackWing Air Cleaner recently.

Is this Blackwing worthwhile in the first place?

Do the following steps to retrieve all the codes stored in your C5:

1) Turn your ignition on. The engine doesn't have to be running, but it's ok if it is...

2) Press reset to clear any warning messages
3) Press and hold the "options" button
4) Press the "fuel" button 4 times while holding the options button down. The car will enter manual diagnostics and start displaying all the codes that are set for every control module in the car.

The diagnostic codes will flash across the screen in the following categories:

PCM - Poweretrain
TCS- Traction control and ABS
RTD- Real Time dampening
BCM- Body Control Module
IPC- Instrument Panel Cluster
Radio- Duh
HVAC- Heating, ventilation and A/C
LDCM- Left Door Control module
RDCM- Right Dorr control module
SCM- Seat control module
RFA- Remote function actuation

"C" after the code denotes that it is within the current ignition cycle.

"H" means it has occured in previous ignition cycles, but not the current one.

When you get the codes you can post them up and we'll see if we can help

BLACKWING require screen MAF?

I am still throwing P0170 and P0174 codes after installing Blackwing air induction. Do I need to change to a "screen" MAF to solve this code?

P0171 Fuel Trim System Lean Bank 1
P0174 Fuel Trim System Lean Bank 2

You didn't have these codes prior to the Blackwing install? You sure you plugged everything back in nice and tight?
