hi, does anyone have any data which would help me understand what my ecu monitor is telling me? i have worked out some of which is boost showing 1.02 bar peak holding at 0.98 which i guess is about right. olts showing 12.2 (engine off) and 13.8 (engine on) maf showing around 0.13 idle and just over 4 wot. afr is reading from 0-900 which i think is m-volts? 0 on deceleration and WOT. if anyone has had experience with the scooby monitor and knows all the other functions and data i would be forever greatfull thanks richard.

my98 uk standard.

 

will translate where i can remember

The parameters available for display:

Engine Speed* (RPM)
Vehicle Speed* (MPH)
Coolant Temperature* (C)
Manifold Relative (Boost) Pressure* (Bar)
Battery Voltage (V)
Ignition Advance (o) ==== ADV
Knock Correction (o) ==== RET
Air Fuel Ratio (Lambda V) ====MV
A/F Correction (V) ===== +/- AFC
Injector Pulse Width (m/s) ===== MS i think!
Injector Duty Cycle (%) ===== IDC
Mass Air Flow (Sensor V) ===== MAF
Engine Load ==== LD
Throttle Position (%) ===== TPS i think!
Boost Solenoid Duty Cycle (%) ==== %DC
Idle Control Valve Duty Cycle (%) ==== ICV


i think thats about right *from memory*

 

what is the lambda showing you at full boost/load ? 900mv is a good figure, mine hits 875mv most of the time, higher the volts richer the map


afc should rock backwards and forwards at idle +1 +2 +1 0 -1 -2 etc etc this is the ECU keeping the emissions in check

knock retard, i believe id this starts going up while you are flooring it on boost, you engine is about to explode this can go up while driving around normally from experience

anything else drop me a PM as i have the hang of most things
