Hi, I do the transmission swap from AT to MT I didn't change the ECU. Before the swap I didn't have any problem with the AccessPort but after the swap when I connect the AccessPort to my forester to read the codes with the engine ON the AccessPort said "Please make sure that the ignition switch is in the ON position". I try with the inhibitor switch plugged in Parking position and didn't work. Did anybody known why this is happening??? Any ideas??

I think you have to swap the ECU don't you?

Do you have a V1 AP? I know the V1 is tranny specific, so if it doesn't match, it won't work.

Im running with the AT ECU and works good but it limits the revs at 5,500, with the MT ECU I wouldn't have that problem.

I have the V2 but the thing is that I didn't change the ECU, is the same that I installed the AP, but now appears that message and the check engine scanners didn't connect.

Well a few hours ago I try again to connect the AP but it didn't work until I disconnect one of the plugs from the TCU and then the AP makes the connection to the ECU :woohoo:

with the TCU unplugged I read the check engine codes and with the access tuner race I deactivate the codes that appears in the ECU and I make a reflash with the AP and plugged back the TCU and now all works fine but when I plugged back the TCU the AP cant connect with the ECU so when Im want to use the AP I need to unplug the TCU.

What a strange issue. Have you talked to cobb to see if theres some sort of work around?
