ej22 into l series related
1:Radiator fan control .Do you use the ej ecu to control or the l setup?is one better than the other?Any tricks?
2:Fuel pump.Is the L mpfi fuel pump up to the job for ej22?
3: A/C.any one got it up and running after the conversion?How?

1: I used the thermoswitch from the L-series to switch twin electric fans (the slimline ones from the MY-series): works a charm.

2: Yes, the EA82 MPFI pump is sufficient.

3: I have not got the AC running yet, will be getting this done within the next few months. I will be replacing all hoses, getting new fittings and re-gassing the system (I will get a professional to do this).

Are you planning on using a ej a/c style harness hooked into the ecu or a stand alone harness or hooked up the ej compressor to the l series a/c wiring thats in place?

I plan on using the L-series harness with the EJ compressor, not using the ECU whatsoever.

1 - EJecu does mine
2. - yes it will run it.
3. EJ compressor with EA electrics with full throttle shut off. custom hoses.(prof made.)

Love the idea of the full-throttle shut-off Chris. Just using the standard TPS? You're a damn genius.

nah the auto pedal box has a switch on it. I looped the compressor through it.

The EJ computer has an ac cut output which will also cut the compressor under high load.

true, I used the old method.

What do you guys do about the absent rotational sensor if using the EA controller with the EJ compressor? Does it just work anyway ?

Chris_Rogers · Post by **Chris_Rogers** » Thu Jun 08, 2006 7:55 pm

all I have done is power the clutch. I left the rest out.

Craigus · Post by **Craigus** » Thu Jun 08, 2006 8:04 pm

Chris, do you have something cycling the compressor clutch on and off?

is this the kickdown switch?

Chris_Rogers · Post by **Chris_Rogers** » Thu Jun 08, 2006 10:07 pm

yup. looking at the EJ harness it seems to be TPS based so I used the switch for this instead.

yep original A/C system is still in place bar compressor which is EJ.

That was my original question - does the EA controller work OK without the rotation sensor connected ? (sounds like it does)

PeeJay · Post by **PeeJay** » Fri Jun 09, 2006 9:35 am

I thought the rotation sensor was only for the fuel pump cutoff on the EAs?

Craigus · Post by **Craigus** » Fri Jun 09, 2006 7:23 pm

No, I mean this rotation sensor:

Or does this not do what I think it does?

stamp_licker · Post by **stamp_licker** » Fri Jun 09, 2006 7:57 pm

its a speed pulser.heres what it does, picks up a signal as the clutch rotates compares it with engine speed and if the clutch is turning to slow shuts off the compressor. i guess there is a way to bypass it or the ej compressor has its own pulser that you could wire in.Ive seen the amount of wires pulled from Yarneys a/c system [alot] and it still worked.
