    p38 eas system in a classic

    Ok, recently bought a 1994 classic to use/fit out for bush camping duties. When I purchased the car the previous owner had ditched the eas for coils. I hate coils!!!! to many years in p38's with eas
    Anyway I went down the track of re-birthing the system. I soon found that many of the components are getting hard to buy through my various suppiers. So i started down the track of using p38 gear, which I had kicking around the workshop.
    I now have the system working well on a p38 valve block and driver module with the ecu still being classic and even a timer delay unit out of a p38!!
    My next move is to mount the whole unit above the cd stacker unit inside the car, behind the RH rear moulding. my reasoning is that the p38 unit is not designed to be submerged like the classic, and I pursonally like electronics out of the dust/mud/sand/water.
    Regards Russell.

    Do you mean the ecu which sits under the front seat? or do you mean the valve block and driver module?

    Its a fair bit of work to relocate that stuff I guess, and the air intake on the classic is inside the car to ensure the pump doesn't get crud in it. I have had my eas on the classic pretty well underwater twice now (not by choice) and it seems fairly robust. The P38 setup is basically the same, the ECU's are interchangeable from a resetting point of view also, I put the classic ecu into my P38 to reset it via the obd2 - serial cable.

    My only planned upgrade is a pair of cheaper compressors piggy backed to my wearing out compressor (new piston ring about 4 years ago) with a second tank for increased capacity.

    yep I'm talking about the eas ecu under the seat still being classic. It's funny the two ecu's (p38/classic) different part numbers but having studied pin placement and operation they are the same. The only real difference in the way the systems work is the pressure switch.
    The relocating is going to involve lengthing the harness and air pipes, not so bad. I'm going to get a piece of harness off a wreck so I'll have the plug at one end to connect to the original driver module and compressor plugs at the chassis. Then do the same at the other end.
    Funny you sould mention the extra tank and compressor, I've got them in the shed waiting for some free time thinking the same thought as you.

    HSE.

    Did you ever consider replacing the P38 gear with the aftermarket Firestone airbag system ? Apparently their available as a total complete replacement for coils !

    Apparently the bellows are designed to support up to 2000kg's per side at maximum inflation pressures, which suits the original design specifications of Rangies.

    Cheerio,

    I've got loads of classic parts that nobody seems to want, shoot me an email if you're interested.

    By timer delay unit are you referring to the AMR1111 relay? Was the p38 part a direct swap or did you have to do some modification?
