0411 swap Issues?
I am in the process of buying a 98 c5 that has already been 0411 pcm swapped. The issue is the gas, oil gauge do not work, speedo 20mph off, traction control, abs and brake light is on. The message center flashes door ajar, traction control needs serviced, check gauges and check engine soon. I was wondering can this all be fixed in the pcm or is there somewhere else to look?

Why would you do the 411 swap on a LS engine ??? The 411 swap is used mostly for cars or trks that are pre LS engines--If your car is a 98 corvette it aleady has an LS LS1a computer in it
There is NO reason to convert a 98 corvette to a 411 swap as a 98 corvette is already an ECM that is LS1 compatitable

I did not do the swap. I am looking at a car that does have it with some issues. From what I understand the 0411 pcm opens up tunabilty for higher horsepower car. If I can't have the issues resolved I will put aftermarket engine management in the car and do what I want with it. I have no experience with the stock operating system.

Most of all on engines with cams/headers/boost/better heads/better intake manifold there are tables to aid in simple issues like start up (warm and cold) engine surging---engine dying knock retard--MAF relocation etc
