I keep getting 68, which isn't a cel at all. Anybody else able to get something I may be missing? It comes on at 5500rpm right after a fuel cut.

What ECU are you running?
What's your setup?

 

P28 ecu, Gsr basemap

Gsr block, LS crank, LS eagle rods, wiseco 9.5:1 pistons, b16 head.

 

Your ECU has gone nuts, try burning a new basemap, or try another ECU if you have one.

Keep in mind the GSR map is tuned for secondary intake runners.

This should probably be moved the Engine Management and Tuning forum.

 

I switched to a b16 basemap, and all was fine. I think it was the secondaries causing some problems.
