ECM re-program chip map data

[racerxmanvfr750]

Anyone out there for a challenge? Swapped out engines. I put a 1995 Legacy Wagon 2.2lt engine, (standard trans.), and put it into a 1997 Outback, (auto trans.). It had the 2.5lt, double overhead cam engine, with a blown head gasket. 

The ECM I am using is for the 1997, the 2.2lt engine needs the EGR valve assembly head. Is there anyway to reprogram the ECM to run the standard trans engine in an automatic? The old ECM from the 2.2lt does not work, or an ECM from a standard trans 1997.

Anyone know of someone who can reprogram the chip?

Otherwise, it's just fix the 1997 engine and reinstall.

Thanks

Ron

change the front car wire harness takes about 4 hrs if you have the doner car the imputs to ecu for trans are many and dosent like to not see its auto why not just put your auto back in ? the 2.2 would work fine behind it

find you an egr equipped intake manifold, swap it on, and read the usrm thread about tricking the ecu, I would link it but I'm on my phone at the moment

The ECU works for both Auto and Manual. The harness in the car grounds a pin on the ECU that tells the ECU if its an Auto or Manual so the ECU knows what to look for.

 

You shouldn't need to change anything to make the 95 engine run with the 97 ECU. You will have a CEL for the EGR but that's all.

If it won't run its a problem with the engine, timing is off, or crank or cam sensor is bad. Maybe ignition coil is bad.

 

EGR code can be corrected by getting an intake with EGR (get the wire harness too) and running a hose from the EGR valve to the intake tube. Or you can drill out the port in the head and tap threads for the EGR pipe. Drilling and tapping is tricky and can cut into the water jacket in the head if done wrong.

Could I take the egr intake manifold off the 97 2.5lt and put it on the 95 2.2lt engine?

Then hook up a hose to pull a vacuum to fool the egr into thinking it is on the 97?

No, it has to be an ej22 manifold, the ej25 won't bolt onto your heads

[Fairtax4me]

2.5 and 2.2 manifolds have different flanges where they bolt to the heads. Has to be a 2.2 manifold. Usually only $30-$40 at a u-pull-it yard, though some of them try to nickel and dime you for fuel injectors, solenoids, and throttle body.

 

You're not using vacuum on the EGR. Thread a pipe nipple into the port and run a section of emission hose over to the fresh air pipe before the throttle body. The EGR just needs to see airflow for the ECU to think its working. When the valve opens it will just pull fresh air from the intake pipe.
