3 Codes after Dyno ???
Yesterday, I had my Vette dynoed for the first time to get a baseline with my current (minor) mod's. The Dyno results: RWHP 313.7 TORQUE 322.7. I checked codes before the runs, and had none. After 3 runs, she showed 3 codes: 28 TCS C1221H, C1222H, C1248H :confused:
Could you please help me here, and tell me what these mean?
Also, misfire occurred, and the air/fuel ratio reading showed 11.7
Thanks a lot!

Re: 3 Codes after Dyno ??? (icom)
Those codes are common when you dyno. They are traction control codes. Your rear wheels were turning and the front was not.
C1221 LF Wheel Speed Sensor Input Signal is 0
C1222 RF Wheel Speed Sensor Input Signal is 0
C1221 LF Wheel Speed Sensor Input Signal is 0
C1222 RF Wheel Speed Sensor Input Signal is 0

Thanks Bigtoe!
I assume the 3rd code (C1248H) is also a traction control code?
Any thoughts to the misfire, and A/F ratio (11.7)?
Thanks

Re: 3 Codes after Dyno ??? (Buckmaster)
Your email was returned for some type of problem.
That is the dyno we use for our dyno days I & II. I have my base line established from them. They are fine, I was just curious. The guys that dynoed at magaflow came up with about 4 hp less and 8 lbs of torque less. Even at Morgan Motorsports they came up with lower numbers than R&D. You need to use the same dyno to really get a true picture.
I want to go back and dyno there again, but $7? is a bit much for three pulls. I am trying to wait on another dyno day, it costs us $22 each for three pulls.
