fans run in diagnostic mode

Hello all, I have just finished up my ZE swap and it runs but needs a few bugs ironed out, ones that i cant figure out. Upon initial start up it ran and idled high, i let the car warm up and it still had a high idle, around 2000 rpms, I adjusted the tps with the fan method, topped off the coolant, and adjusted the disty more in the center. When i started it up the idle was high then came down to about 7 or 8 hundred and sat there until i revved it then it rose to 2000 and stayed there. After a drive around the block a CEL came on and when placed in diagnostic mode the fans came on i tried adjusting tps but it had no effect on the fans. no codes were produced, i have a probinator chip and i think the no CEL comes from that, the light comes on stays on then goes off. Has anyone found a way to pull codes with this chip? I appreciate everyone's help i tried a search and couldnt produce any results.

Thanks
Bryan
