Yes, EAS again..

Hi guys, nice forum. My first post here, because my p38 EAS will soon relegate me to the madhouse. Began with a leak on a rear airspring. Replaced both. While I thought it would be good to renovate the air pump so I did.Then I switched out all o-rings, and the diaphragm in the valveblock.When everything was back in the right place, (I hope), I start up my Landy, and the bloody thing only rises just on the left side!, (Thought it would tip over .)
Then tested to turn manual EAS button and surprise, when i tell it to go to the access-mode the damn thing rises even on the right side .
Someone out there has any idea what could be wrong. Is it Bill Gates who sneaked Windows in any ecu?:nospamhere:
(btw, sorry my english , just a swede.... Toby

You may have put the solenoids back in the wrong place. Rear should rise first then front. If you have one of the rear solenoids on a front valve and the EAS has lifted a front wheel instead of both rears the front sensor reading will send the ECU into. What the **** mode.

Have I misstaken the "ports"? Isn´t number 1 and 2 the rear ones? I haven´t find any good description on which portnumber goes to wich weel on the valveblock.

It's difficult to get the pipes in wrong as they are loomed and should just sit correctly. But if you had the valve block apart it's easy if you don't number them, to get the solenoids in the wrong place. Solenoids MUST go back where they came from otherwise ECU gets a signal from sensors and lifts wrong corner. Looks like you have a front where a rear should be. If for instance it's lifting the left side initally instead of both rears, you have the L/H front where the R/H rear should be. Or other way round if it's lifting the R/H side first.

Ok thank you, I belive the same, but can you confirm that the one marked 1 and 2 are for the rear and 3, 4 for front, so I can test by the connector wich solenoid is "klicking"

OK description as if you were looking straight at valve block towards where pipes go in. There are four sockets for airbag pipes. Two at right are fronts and two at left are rears. Top rear one should have a pipe colour coded RED in it. That feeds. Left rear bag. Bottom one should have a pipe colour coded BLUE in it. That feeds. Right rear bag. Top front one should have a pipe colour coded GREEN in it. That feeds. Front Right bag. Bottom front one should have a plain black pipe no colour code. That feeds. Front left bag.

That's what I call an explanation, thank you very much. I have searched for a drawing like that, now out and testing...

:clap2: I owe you a pint!! Had mixed up the underside coils.

Just have seen your pl4,as an old SAF Captain, this is how a cockpit should look...

Not quite as elaborate as that, a bit more basic. Had a few Swedes over here working in carbon a few years ago making bits for i think JAS39. Good lads. Anyway your sorted now. Good luck with it.

Maybe OT, but did you make in the 2000 hours, as of the Pazmany.com and do you realy use a vw-engine?

Think the 2000 hours is for the kit. Did not make it from a kit. Bought the drawings made all the tooling, forming blocks etc from the drawings, then made all the parts then built the aircraft. Made everything myself even the canopy and screen. Took a bit longer than 2000 hrs. VW 1600cc converted to 1835cc by myself was used to power it. Sold it a couple of years ago. Suppose you could guess from the registration what my first name is.
