Sct Xcal 3 - Error 1034 And 1016

[astroinc]

Hi Everybody,

Please Help!!!

I have a FG 6 speed auto that has been custom tuned with the Xcal 3 about 2 weeks ago. The tune was great up until I flashed it back to stock for the first time, because the MIL indicator came up and I wasn't sure if something was going wrong (I have since found out this is the second o2 sensor) . It returned to stock OK. I tried to flash the custom tune back it came up with a lost connection error message. I think the code was 1016. I tried it again and it came up with "download failure detected and will not let me progress with the custom tune.

I took it back to my tuner who suggested I try flashing it back to stock first, then retrying the custom tune.

When I tried flashing back to stock, it seemed to go OK loading the engine to 100% then to the unlocking ECU stage, then it was at the "please wait" bit and came up with "download failure turn engine off". I tried the custom tune again but I still got the error message 1034 saying to revert the car to stock if it will not start. I checked the DTC's which came up with 0100 and 1000? I am not sure what these mean?? I cleared these on the advice of my tuner.

Does anyone know how to troubleshoot this or is it a bad xcal3? It is very disappointing after 2 weeks to not even get to use the Xcal 3 and be stuck in stock. At least the car is going!!

Any help would be greatly appreciated!!

You took it back to the tuner and he doesnt know whats going on? Would have thought it was up to him to sort this one mate, especially only 2 weeks after the tune. Take it back and tell him to call you when its ready -his prob.

hook up a battery charger and try a reflash to stock , then back to custom!
