NS Pajero fuel cut-off, EDS gauge.

Thanks RMD. The GPH information normally comes from the vehicle, but is not shown as supplied by the NS so I can't call it up. The manual says that I need to see how the GPH changes between idle and 1500RPM to determine if the EDS should be set to diesela (engine with cut-off) or dieselb (engine without cut-off). I'll try a drive around this afternoon looking at the TPS readings when I lift off the throttle, but whilst the TPS might indicate zero when I lift off, that doesn't necessarily mean that the fuel has cut off to the injectors. I run 300:1 2-stroke mix in the car which lubricates the injectors so they make almost no noise at all; very difficult to hear injection stop!!
I might try setting the EDS to imperial units and see if GPH appears as an option, which should then enable me to confirm diesela or dieselb. I just thought someone on EO might have the answer already.
If diesela, I then need to input a cut-off value into the EDS. The EDS factory default is 24, but the manual gives me no clue as to what this number means.

Not sure what the EDS is asking for but if the throttle is shut and on decell, then the injection will stop until the predetermined/pre programmed speed of idle is reached. Probably, haven't tested this, but the injection in a petrol engine resumes around 300 above idle speed so no dead spot. The diesel would be similar unless dropping down to idle speed. The ECU will read the TPS and resume some injection if the throttle is held a portion above idle and take up from that point. Speed , load and boost level will all have a bearing on it. Can't imagine it will be "B" as you mentioned. I am under the impression all the sensor and delivery of fuel quantities used for injection purposes is what most readers use from the ECU and the data is fixed by the program. All the reader has to do is present it to you.

With the 24, it seems to be a value of the total TPS value. Not sure what yours will show with throttle fully open.

Thanks again RMD. The TP spends a lot of time at 100 under load, but reduces to about 19 at 80km/h in 5th. It never ever drops below 12. The instantaneous LPK never ever drops to zero even on over-run, so I'm not sure what is going on. We are about to hit the road for the long drive to Coffs with the van on the back so I'm looking forward to playing around with 4th or 5th and different towing speeds to see what is the most economical. We have a lock-up clutch kit fitted which has improved our round-town economy by at least 1 L/100km so we'll see how it affects us when towing. We also suspect (somewhat strangely) that we get better economy at 100 than 80 km/h. This could be that the engine is happier at higher revs, or the air flowing over the Pajero doesn't have time to drop down into the gap between the Pajero and the van, but flows straight over the roof of the van??????
