Turbo KADET JWT CPU upgrade

[Turbo 510]

I am in the process of turbocharging a KADE. It has all of the goodies in it and is run by a JWT remaped stock computer. The problem is that it will not maintain a steady idle (acts like it's loading up). and after it goes into closed loop operation will not idle at all. I drove the car for the first time a couple of days ago and after a realatively mild pass at low boost the computer went in to limp mode. The computer flashes a code 55 which according to the shop manual, is "nothing wrong with the above circuits"(the ones capible of self diagnosing). The readings from the O2 sensor appear normal. The engine uses the 300ZXTT injectors and JWT has been no help in getting this thing to run. Has anyone out there had any experience with the JWT computer or ran into anything like this? Help me get this car on the road!

Well, I think this is an extremely long long-shot, but we replaced the engine in my brother 93 Z71 Truck and it loads up real bad when its idling and it throws a code, but it says the computer is bad, what we found out is that the coolant temp sensor was blown and it was telling the computer it was running at -30deg. When it did this it started to load up at idle, and when youd go to step on the gas, it would just take a crap and die. Dont know if this is the same, but its the same idea.

BTW, Your in Ptown eh? Im just down in salem.
