I have a 99 GSR with a Greddy turbo kit (RC 310cc injectors) and still utilizing the Blue Box for now. All was fine while running the OBD2 computer. After converting to OBD1 using a converter harness I get a CEL code 16 at the top of 3rd gear. The code will go away after I shut off the car. The car will be normal so I can drive and boost as I please but when I reach the top of 3rd gear the car falls flat on its face and instantly goes into limp mode (3500 rev limiter). The blue box was initially tapped into the factory harness then I retapped the converter harness and the problem did not go away.

I've read a couple of archived threads and see that I'm not the only one with this problem. Has anyone run into this problem and figured out for sure how to resolve it? It seems like nobody has found a solution for this in the archives. Any help would be greatly appreciated. TIA.

 

Someone's gotta know the answer to this.
