Timing Issue

For some reason its giving me a solid -20' timing when I datalog and you can clearly hear it needs timing advanced, running a map that ran perfect before, although it was 2/3 engine/setups previous on this car. Got the fuelling, etc right, it can rev, but not freely, due to lack of timing, I am missing something, or am I using wrong crank angle sensor, although the plug fits on this model and not the other?

Many aftermarket ECU's have calibration for the engine timing, but I can't find any such settings?

K20 stock with Jackson Racing charger and 500cc injectors.
Removed a K24 N/A which ran perfect, with another map and same ECU.

IAT and ET not yet connected/calibrated

If your IAT is not connected then VTC will not work.

Serial Number on ECU 37820-PRC-0232070-403586 been converted to K-pro
Version 1.4.1.0
Calibration, using the std one off the software for Jackson Racing supercharger on K20.

Ariel Atom 2
Keihin ECU
Stock K20 with supercharger, known as a Atom 300.

Gives a constant -20' Ignition angle

PLEASE I need to get this car right, I've checked everything I could on the engine.

Only error code that comes up is P1316, but its a similar code always present on Motec I also use on these engines.

You have errors from both intake and exhaust cam sensors. You need to fix these before the car will run correctly. Usually the cause is the wiring to those sensors - follow the test procedure in the manual.
The multiplexer error can be fixed by disabling the multiplexer output.
The idle value error indicates that it needs cleaning or is faulty.

I can't seem to find a "test" section?

I've swapped the cam sensor wiring, no change.

I'm not worried about the other 2 error codes, I just need to sort out this timing, what can it be?

You must fix the error codes before you do ANYTHING else
