Today I set the air suspension back up on my P38. It had been driving me mad as it was just not right. Bad ride even though it sat right. The setting the EAS using a tape from wheel centre to wheel arch is no good as you have no way of knowing how much pressure is in the air bag. So the car always ends up feeling like it has a broken spring.
Solved this by making some calibration blocks. Using the blocks on just one axle at a time and taking the reading from sensors with body sat on the blocks gives 100% accurate reading. I recorded the readings and did the same for the other axle. Then imputed the new readings in to the EAS ECU and saved the readings. I did this for the different hight's.
The difference is remarkable the car drives nice and balanced and drive over the rough roads like it did when I first got it.
So then it was off to fill it up with fuel and find some bumpy roads
