Hi. i never got a spec list with my ECU which was from a retailer a few years ago that i cant get in touch with. I got it with dual knock onboard, and the signals from each sensor are wired to EC18 pin 1 & 2. When i look at the view 'analog inputs all' , ch 0 and ch 5 ,which are normally EC18 pin 1 & 2, still have changing values, is this normal? The reason im asking is that i thought that when there is a dual knock chip the analogue channels on those pins arent used anymore. Knock sampling seems to work but i havent tried to calibrate it properly yet.
I have a question regarding other analogue inputs. ....1)I intend on using an input for E85 flex-fuel sensor. The wheel speed input to EC18-8 is already wired to the OEM VSS sensor. Am i correct in saying that i need to sacrifice the Vehicle Speed Sensor to use EC18-8 for the E85 flexfuel input or have i other options??
2)I want to use another input for enabling launch control. Just a grounding switch, i see an unused input that has 5v and is unused. Is it safe to use it??
Is there a way to find out using my ECU's serial number to know exactly what spec my ECU was actually built to?? Or would some of you more experienced guys be able to tell me by looking at the board if i take off the ECU covers what i have as far as input protection etc?
thanks in advance.
