timing is pulled, not fuel

It depends.
Near redline fuel may be cut off instead of ignition delayed.

from what i've studied, 05-06 bounce off rev limiter (fuel cut) when in manual mode, 07-09 timing cuts and will shift at redline in manual mode. if the transmission clutches, including but not limited to input clutches, are worn, the rpms will jump higher and higher between shifts, sometimes leading to a rev limit hit once in a while. key here is to cut DBW RT to 66% after 6100rpms, this reduces the chance of hitting limiter and also reduces clutch wear during shifts.

In my case both timing and fuel is pulled making the first wot shift interesting. Somehow the ecu learns though and the second shift is already much better.

If you are referring to the table "Ignition Timing Compensation AT Shift Retard" that has been available in the AP's - I've found it. From what I can see in the literature, it's only available for the 09/10 forester XT and 05-09 LGTs.

Here's what it looks like for AZ1G101N. What's interesting is that the table is also there in my 08 EDM Sti - but completely bypassed by the logic.

On my 04Forester XT, the injectors are shut off at the shift point. My wideband goes from 11 to 18 when it shifts, which leads to knock. Kinda why I wanted access to a table that can reduce the timing during the shift to compensate for the lean fuel mixture.

so i was running the manual file in my automatic..... it seems to have a minor issue with delaying the throttle opening under certain conditions. from what i read on the other post linked to this one that can be remedied with adding a clutch switch...... this is where i ran into several problems, and switched back to an automatic file

first, the pin out shows that the auto has the power and ground backwards for the neutral safety switch to what is needed for the clutch switch. the second problem is that if i just apply power to the circuit the way the schematic shows will the car start? its going to think the clutch is always out? we used a very low wattage fuse and applied power to the ecu lead after removing the wire from that circuit, and it immediately popped the fuse. the guy that was doing this in the other post is foreign and a little hard to read, and he doesnt appear to be on the site anymore to ask any questions. after all the trouble i switched back to the automatic file..... but seriously it sucks. the manual file worked so much better at shifts. i wish there was some way to make the auto file shift like the manual file. i'm seriously considering the valve body mod if it looks like this project will never take off. night and day difference in drivability with the timing retard at shifts disabled.

So far, I have not seen this on the sh9 (forester 09 to 11). Timing is reduced at shift for the turbo to keep its spool up. Removing this all together will make you lose boost after shifting. However for stock turbo, you can reduce this a bit to give a smoother drive.

Your issue may be different, could be timing just too high at shift point or your timing tables are not as smooth as it should be. Have you compared logs with another 04 forester, a stock one? You need to know if it leans out on a shift.

e-rue:

I didnt experience any issue. Does your car have a TCU? I dont understand why your car has a problem, as long as your keeping the ecu physically there and just switching the map there shouldnt be any noticable problems. Especially no CEL's. No crap with neutral safety switches or anything needs to be done as long as you keep your ecu. I really only think the AT maps do is pull timing/cut fuel for shifts, i havent heard of any other altercations

e-rue - what CAL id are you running? I've found this table in the later roms (ask MFB how he knows how it works out )

Maybe I can find it for you on your rom.

erue,

How did you manage to run the manual ecu file in your at?

you guys don't have a forester xt mt map?

All of the 04-05's have the same fuel cut at shift points, I've seen logs of others doing the same thing. Same with some WRX logs I've seen too..

its not complicated, you just flash the ecu with the manual file.......but theres something wierd with the idle and tip in stufff when i use the wrong file. there a link to another post (in this post) where a guy was having similar issues, and he fixed it, by im assuming, applying power to the clutch switch input..... although i cant verify that, and i didnt not have any luck when i tried it.

not sure i want to go back to that, unless i can figure out how to get the clutch switch so the ECU doesnt always think the clutch is depressed.

heres both of my files if anyone wants to take a look for the timing retard, and try to disable it.

FYI.....its an 05 forester xt with a fully built engine, 4" MAF and an E85 blend.

damn bro, 40* at redline, "dat e85"
