I am still working this 60 Corvette Correction Vette. With the 05 LS2 GTO drive train.
I have been unable to get the CASE relearn to function. It faults out with an
' FI or Ignition fault' present (thats all it says).
While looking at live data I came across an interesting reading.
This may seem like a 'No Duh' question but when you are looking for an odd issue you have to check all the basics.
Under live data and at idle the cam sensor RPM is almost correct @ 1/2 of crank, but as you increase actual RPM's to over 1000- cam and crank RPMs read the same!
Please tell me this is not normal!
Last time I came across an issue like this was on a cup Porsche that had a cam sensor shield wire in contact with the crank sensor sig. wire. Thus when looking at the output you saw two crank signal RPMs- causes poor running.
Also I have noted that there is no Relay Feedback circuit at C1 18 also known as accessory voltage.
