  1. Need known good air fueling readings

    Range Rover Mark II / P38
    Troubleshooting a problem that just came about this past weekend. It's a 2001 4.6L HSE. Was hoping someone could provide known good values from their rover that is all warmed up and idling. What I'm looking for are the following from the "Air Fueling" section on the Nanocom: MAF Sensor (g/s)...
  2. Second engine rebuild - compression readings

    Range Rover Classic
    Ok so for those that remember, I recovered a low mileage 1983 original Texas import Range Rover (3.5 Carb). It has not run since 1997 when the PO removed one head and it had been sitting since (mostly in a closed garage). PO bought plenty of spare parts and I bought the lot for cheap from the...
  3. 4.2 supercharged maf readings

    Range Rover Sport / L320
    Hey guys. Since I've owned my 2007 rrs supercharged, I've always felt like it had slightly less power in higher revs than another one I test drove before buying this one. I now have an iid tool and can see that it has no fault codes. I've tried cleaning the maf sensor with the proper cleaning...
  4. 2010 Bouncing instant MPG readings

    Range Rover Mark III / L322
    I have noticed this for a while. But I am now getting an occasional CEL Code P0420 for bank 1 catalyst inefficiency. It’s 2k for a new pair.. and the light sometimes goes out itself. I replaced downstream O2 sensors and problem stayed away. Anyhow, holding steady throttle on a flat surface, the...
  5. Nancom live battery voltage readings, GEMS

    Range Rover Mark II / P38
    Hi I recently upgraded my nanocom and started using the live capture feature One thing which stuck out was that my battery voltage seems all over the place! I have a voltmeter in my dash and it is fine, so is the screen reading on the nanocom. I have attached graph and I wondered if anyone...
  6. Gearbox hydraulic pressure readings

    GAP Diagnostic
    I've been monitoring/logging gearbox behaviour these past few days using the live values logging and then analysing on on an Excel worksheet. The tools logs a lot of valuable information that has allowed me to check that there is no slip in each gear, the TC clutch seems to be working fine and...
  7. Battery/Alternator Readings

    Range Rover Mark III / L322
    Looking for some info re what are normal voltage readings for a L322 battery and alternator. Background: Yesterday I got the ABS Brake and HDC fault, and the radio switched bands which lead me to believe there was a voltage drop. Turned the truck off and back on, no faults. The Truck is used...
  8. Querying a couple of sensor readings - GEMS

    Range Rover Mark II / P38
    Evening, Trying to get to the bottom of some running issues, one of which I probably have the answer to but nevertheless... I've done some searching and couldn't find any definitive answers. Need some of your expertise :) Throttle position sensor - in the gearbox ECU through the nanocom, with...
  9. Any hack for TPMS Readings?

    Range Rover Sport II / L494
    Is there an easier way to read our tire pressure? Like how about when the car is on? That whole process of hitting "OK" over and over while the car is off so that I can get to the service menu is really a pain.
  10. EKA code problem and lockout, and Nanocom codes strange readings

    Range Rover Mark II / P38
    EKA code problem and lockout, and Nanocom codes strange readings Hi guys, having a big issue getting my Range Rover P38 2.5 Diesel to start after a flat battery, the problem started after reconnecting the battery after fully charging it, I had the key in position II in the ignition without...
  11. P1171 and P1174, MAF readings are normal.

    Range Rover Mark II / P38
    Everything I have read on this indicates that its an MAF issue, but my MAF readings are totally normal; 5/6GPH during idle, going up with throttle. What else could it be?
  12. Altitude readings are inaccurate. How to calibrate?

    Range Rover Sport II / L494
    I just noticed under the 4x4 menu that the car gives altitude readings. However, my car is consistently reading about 100 feet below the actual altitudes for any given area. For example, my home is ~ 150' above sea level but the car tells me that we are ~45' above sea level. I don't live on...
  13. MPG Readings

    Range Rover Mark II / P38
    So today, out of the blue, I noticed my MPG dash reading just starting to crash from 12.9 (my usual town mpg)... it drops by tenths in seconds.. 12.8, 12.7, 12.6, and so on... then stops around 9.5 and occasionally will start to climb back up to mid 10s. During this erratic behavior I...
  14. Emissions MAF p0102/03 & low g/s ODB air mass readings

    I have a 1998 P38 4.0 which has seriouslyfailed it’s MOT emissions. The vehicleshows no sign of a performance problem apart from recently, when sooty blackdeposits have been evident on the garage floor and fuel consumption hasworsened but it usually isn’t good as my journey to work is only 2.5...
