Put the min and max WGDC at 90%, lower the timing, run really rich, strap it down and see how much air it pushes.

Ok, so here is the next question. We have timing pretty much figured out (need a little more logging, but I am doing that). There is still this laggy throttle plate where the plate angle does not match the pedal angle (lags behind) during cruise (closed loop in my logs and a little bit in open loop). Freon mentioned on Nabsico that it may be a non-issue as we can just tune the car to enter open loop at the correct time and the throttle will behave agressively like it should. His main question was, if we had the ability to run full throttle opening in closed loop (we can there is just a second delay) would we even want to do so? The car drives fine the way it is now with the limitted throttle angle until in open loop anyway.

I think most of the things we need for the 07 STI are there now. Thanks Bill.

Just PM them to me


I've created a fix for that. It affects roms 521N and up for the 05 LGT (possibly the 06, but I haven't checked that). Subaru did this to fix a "surge during moderate acceleration". Really it just hampers the car. The 07 STi has the same code, however, the constants are setup in way so that the wacky behavior is disabled as far as I can tell. With the logs of the test parameters I sent you, I'll be able to tell you if anything strange is going on.

I would see if you can get into open loop with the minimum throttle as possible and then once it switches to open loop, go WOT quickly and see if the throttle lag is really limited to closed loop.

I'll try and get a log of that. In closed loop at least the throttle lags (plate stays open at max 30 or so) until ~70% pedal angle then opens fully. I'll see if i can get it into open loop with ~30% pedal and then punch it.

Also, I need to do more testing on what the deal is after reset. If you set the IAM to 1, the ECU does some weird timing stuff (you can feel power drops) for a good bit until you have driven the same amount of time that it usually takes for it to rise from .5. I am wondering what advance maps it is using like you stated in the PM.

if you look at the screen shot for the desired torque map, I think that's the culprit when you are talking about the throttle thing

The map has a raw tps value of 27-31 ish, then jumps to 84 (WOT). If you smooth that table out some, you may find that it doesn't do that laggy thing anymore.

IF you look at the bottom table, it shows that at 71% pedal, the desired torque is 360Nm. If you then go to the top map, 360 Nm is 84 TPS.
That would totally explain his 70% throttle plate dealy

that screen shot IS the 07STi ROM

I gave Merchgod logs. He may find something in the code or have a test for me to do.

Here's a SS of that table (07 sti top, 06 sti bottom) with the necessary conversion. You can see that the 06 sti is way more progressive in throttle plate opening % (if that is what it is). This table could be the TPS target. That is, the ecu attempts to hit this target based on what we currently call the 'throttle actuator duty' table as an input. Then adjusts the throttle motor duty until it hits the TPS target (similar to adjusting wgd to hit target boost). So, changing the values in the 'throttle actuator duty' table will effectively change the TPS target based on this new table. If this is the case, then maybe this could eliminate the throttle lag all together.

lets do it!

send me the memory addresses and I'll add it to my def, if you'd like.

ooo please let me know how to implement the fix! It's so annoying trying to hit peak boost and NOT.

It requires a code change. You can send me the LGT rom and I can apply it. I only have it done for the 521N and 522N.

throttle maps worked great.
That is surely the map to fix the throttle response.

Car has awesome no lag response now. Lovin' it!

GO TEAM!

sounds good. Did you base it off the 06 sti table?

I made my own, but it's pretty close to the 06.
It's almost a smidge too aggressive, but I love it.
here's the ROM and the screen shot of the only change.

Cool, we need to get Gabe to see about working this into the Stage_0 ROM for the STI07.
