Hello again,
Thought I would post up my current stored height values for the experts to give me there opinion on,
FL , 133, 108, 92, 64.
FR, 132, 107, 91. 63
RL, 126, 107, 96, 74
RR, 126, 107, 96, 74.
These are the figures that were stored into the EAS ECU when I purchased the car last June , first time I plugged in the software I wrote these figures down for safe keeping. Still having my half inch higher on passenger side front issue. As you can see the front left stored height value is very close to the expected ECU limit and if I try to bring down the difference the ECU does not like it and reverts back to its on stored values. Do mine look ok or are they a little to low.
Thanks in advance and determined to fix this.

Looks about right although im suprised the rl and rr are identical
Get yourself a tape messure and check that
 
The numbers don't mean a lot as long as they are within limits, all that matters is that the car sits level and at the correct measured height for all levels.

Here are mine for a comparison with the actual taped measurements

 NSF OSF NSR OSF


Access height: 730mm +/- 7mm

50 48 53 51

Low 770mm +/- 7mm

81 77 73 75

Standard 790mm +/- 7mm

93 89 79 81

High 830mm +/- 7 mm
112 118 115 116

Hope this is of some help

excellent, thank you very much, might just put in your values and see where she sits.

Which is a daft thing to do. All those numbers are is a digital representation of a voltage output of (or resistance of - can't remember which way round they work) the potentiometers which are the height sensors, height sensors are variable in their resistance, they can be fitted slightly differently, the arms can be slightly bent - there are so many variables.

My settings looks quite like yours, do not recommend using someone else settings.
You must do something wrong or out of range if ecu won't accept changes you make, has this not been debated once or twice before btw?
Raised the RR yet?

Ok, understood, just at my wits end at the mo and will take any suggestions to sort this problem, have taken sensors of a number of times and checked them together , bothe exactly the same ( brand new), have swapped them over but nothing is working at the mo:mad:

Wouldn't do that if i was you, many of his readings are below the limits for the heights. Something is wrong there. Access: Front must be between 50-110. Rear 50-100. Low: Front 75-100. Rear 75-120. Std: Front 95-150. Rear 85-130. Extended: Front 120-180. Rear: 105-150. You should not be able to enter any beat count lower or higher than those for each height setting or the ECU will default. Your FR setting is actually lower than your FL setting no wonder FL is higher.

Ok, have been trying again for 3 hours today still no joy, what ever height I take the car to still can not get FL to come down that half inch. I can get all other corners to move either up or down but front left will not adjust wether I change it by 1 bit or 10 bits, am I doing this correctly?
Start engine,
Plug in laptop, car beeps.
Connect comms,
Iniatalize,
Wait for FF
check for faults,usually vehicle has moved,
Clear fault,
Unlock EAS,
Go to callibrate tab,
Press read all,
Then try to callibrate?
Is the correct order of things?
Am thinking of purchasing another EAS ECU, I understand they are usually robust but cannot think of anything else to try now:mad:

Try without starting car, key in pos 2

Not correct, you plug the cable in and connect to the laptop, start the EAS software and select the correct port if necessary, turn the ignition to position 2, clic on initialise on the EAS and wait for the green "Good Idle" if you do not get the green good idle you do not have comms.
When you calibrate, do one level at a time, if any level is out of limits all levels will go to default, you do of course have to write the new values back.
Other than that, correct. when you have finished, stop the EAS software, turn off the ignition and then unplug the cable.
You could always raise the other side to match.

Half inch trench, more like an 8 foot trench and drive it into it, what difference would not running engine make? Bit worried about flattening battery.

So you disagree with the creator? FF is good idle and he can see the vehicle moved fault no sensor or other faults, ie connected

Creators how to videos in the link in earlier post

You can gett FF and not have good idle.
 
Would one of you kind gentlemen have a spare EAS ECU that I could borrow for a short while? Will happily pay for postage and add a few beer tokens. Could be worth a try because I put in some way out of range values into mine at the weekend and it did not revert to factory settings? Also I think I will remove front bags and swap them over just to see what happens.
