Yes your correct.
I remember having the bubble trace on and it was in the 100kpa field at idle.

Was that in the idle spark table or the main spark table? Would assume it would match up anyway.

Just a couple of basic things that come to mind. Other than the wideband reading does the car run okay? Also, when you calibrated your wideband, did you remove the sensor from the exhaust? Not doing so could cause the calibration to be out.

Hi guys.
Yeh motor actually runs and starts better then with the active manifold.
Plugs have lost most of their colour which suggests its got no fuel.
Manifold come off last night, confirmed no mechanical issues.
Will put it back together tomorrow after work.

i'd suggest just start changing the tune and see, if you can get it to correct AFR's and the ve table looks ok then its probably right, but if you have massive dips or rises it might indicate something is wrong!
