no problem
Evo3--------Evo8
pin 40(wastegate sol.) ---- to pin 11
pin 8 (fuel pump relay) ----- to pin 22
pin 71 (gound) ---- join with wire at pin 26 (ground)
pin 33 (fuel press sol.) ---- to pin 3
pin 22 (AC comp.relay) + pin 11 (fan relay) ------- pin 8 (AC comp.relay)
pin 3+16 (rad fan high/low) -------- pin 32
add pin and wire to pin 79 (flash pin)
these are the changes I've made to swap E8 ecu in my E3. I think DSM's wiring should be pretty same

Its also not necessary to connect 11 to 8 because the 8 ECU controls 32 and 34 based on A/C .
The ground at 71 doesn't need to be connected as the 8 ECU doesn't need it. According to what Thomas Dorris from ECM Link told me, this wire is for the park/neutral switch code which is in the Evo 3 ECU code even though obviously they never came as autos.

So i switched back to 96531706, the jitter was driving me nuts on Sd 2.0, i hope they eventually get that worked out.
Anyways, while setting things back up on my 1706 rom, trying to get the idle dialed in (a/c on has always been an issue) i noticed something. Without the a/c on my idle is pretty decent and generally the car never stalls. With the a/c on i have always been chasing the clutch in stalling issue and figured it was just an issue with ISCV tables getting dialed in correctly. Today though, i noticed with the a/c switched ON, my ISC steps stayed the same as they did with the AC OFF. So i decided to log the AC Switch and AC relay in Evoscan. AC relay never changes from 0. AC switch irradictly changes from 1 to 0 whether the AC is on or off.
As per my previous post the only wiring going to the ecu for ac is as follows
For the AC I have
EVO Pin DSM Pin
08 --------- 65
24 --------- XX
31 --------- xx
32 --------- xx
34 --------- xx
45 --------- 07
I guess working perfectly was an overstatement!
Any ideas or suggestions?

Ok, according to what im seeing in the FSM, Pin 24 at the EVO ecu ties to the AC Control Unit at Pin 5.
This appears to tell the ECU when the Ac is under Hi or Low Load. It just says that under Low Load (Ac load that is) it has Positive Battery Voltage, and under Hi Ac Load 0v. I would guess that 0v would mean ground since currently it has 0v since its wired to nothing.

I know this probably a dumb question but oh well. A buddy of mine said in ECMlink you can do the base timing in the software itself. My question is can Ecuflash do that as well?? Or should I just do the whole alligator grounding setup??
Thanks Alex

Meaning I don't have to do anything in the engine bay correct?? Just get the car up to running temp and make my changes right?
I'm still learning and understanding everything so pardon my ignorance haha.

Well you will have to adjust the CAS to make sure you are seeing 5* during the testing procedure just like you normally would. Only difference is the ecu is taking care of the wiring.

So I tried to start my car today for the first time with the E8 ecu and it wouldn't start. I was able to set the base timing and start my car with my stock ecu. Could it be because of the immobilzier key??
Thanks Alex
