1970 Corvette Conversion-P0452 Code I have been working on my convresion and am ready to bring it home to my house. We have been doing all the work over at my buddies house. So far everything has been going great. I have let the car run as long as a minute or so since it is indoors at this point.
I have recently got HP Tuners so I could do some of the tuning myself since I have done everything else. So I am a very much a NEWBIE on HP Tuners. The donor motor came out of an 02 SS Camaro with an Auto. The 70 Vette is a 5 speed manual.
Before I head out on the road home with the car, 25 miles, I want to be sure I am not going to be stuck somewhere in the limp mode. I have code P0452 showing on the VCM Scanner which is described as Fuel Tank Pressure Sensor Circuit Low Voltage. As you can guess I have none of this system installed. None of the EVAP, AIR, EGR etc. When I look at all of the DTC codes in Editor, I only have 10 showing that I can manipulate, P0101, P0102, P103, P0106, P0107, P0108, P0111, P0112, P0113, P0116.
Where is it that I can eliminate the P0452 code? Any help offered is greatly appreciated.

When I am looking at the current tune for the 02 PCM, there are only 10 DTC's listed and that is it. Maybe I need to take another read on the PCM and see if the rest show up. Any ideas on this?

I have learned that if a car has been tuned at some point with another brand of tuner other than HP Tuners, HPT will not read those codes. What I understand it HPT speaks in a language equal with GM speak. Other tuner stuff is a language on its own. This way EFILive or HPT or LS1Edit cannot speak together. My donor motor came out of 02 SS camaro and when I got the motor, it had SLP headers, cats, y-pipe and identification plaque on the passengers side head. I assume that SLP tuned the car before it was sold by GM. SLP must use something other than HPT.
To get my full bank of codes back, I have to get a stock tune from another camaro and overwrite my tune. I think this is correct.
