Hi Tom,

Yes I have tried that.

The figures I am getting back don't match what is indicated on the boost gauge.

I will post up some figures from the datalog later, however if I start the datalog with accessories on but prior to turning the engine on, the datalog for the AEM boost gauge (with the equation applied to the RAW 0-5 v) returns a value of around 13. Obviously with the car off this value should be 0.

I will re-check the wiring tonight however I don't see this being the problem. I will also complete a datalog of all analog inputs 1 to 4 to see if it is somehow being picked up on one of the other analog inputs. I don't think this will resolve my problem either as the analog input 2 is reading between 0.5 and 4.5 volts as AEM advise the analog output fror their boost gauge should.

I've had no issues datalogging the AEM wideband by applying the formula through livelink.
