Pull your ROM and see. The different model lines don't always get the same changes in the same years.

Yea, that's kind of the problem. I don't have my stock ROM anymore. While opensource tuning, I used a base map from online that said it was for my car, but wasn't quite right. And like an idiot, I lost my stock map. All the ones I've seen from 05 so far are a linear increase to 100 requested torque. But what if my car is supposed to have requested torque numbers like in the 200s. My car is really slow right now with the current map, and I'm wondering if this could be the reason.

No. So long as the Pedal Angle>Requested Torque table has the same max RT value in the 100% pedal angle column as the Requested Torque>Throttle Opening Angle table has for max RT in the column that gets you 100% TA, you're getting everything the engine has to offer.

Basically, the requested torque numbers have no meaning. All that matters is that both tables max out at the same requested torque.

Of course, cruise control seems to care, but engine power output doesn't.

Well, there's no question in my mind that my car is down on power, and I'm fairly certain it's related to the map it has on it. My 2.5i baja with 257k miles would completely smoke my legacy in a race. I also noticed that when I logged data, percent engine load never gets near 100%. At WOT, it hovers around 50%, and even near redline it's like in the 60s at best. Also my peak airflow is down like 40-50%.

Never look at percent engine load. Only look at engine load in g/rev. The percent engine load is a meaningless spec that the car actually isn't capable of reaching 100% of.

Log Throttle Opening Angle. Does it reach 100% when you put the accel pedal in the carpet? If TOA doesn't reach 100%, does pedal angle reach 100%? If pedal angle doesn't reach 100%, you have a physical problem, not a software problem.

Throttle does say it's opening 100%. I even checked the butterfly valve physically just to be sure. Nothing is mechanically wrong with my car.

Take the torque box off so you can see the throttle directly. Have someone step on the gas (key on, engine off) and visually verify that when the logger is reporting 100% TOA, you actually see the throttle plate 100% open. If it opens all the way, you do not have a DBW problem. If you see that the throttle is not physically open all the way when reporting 100% TOA, you need a new throttle as the sensor and motor are not available as a separate part.

This is exactly what I did, and it did open all the way.

Ok, but something else is wrong, probably with the map. I've tried 3 or 4 2005 legacy 2.5i maps, and they all keep my car slow. Now if I could only get my hands on a PZEV one.

Whatever's wrong has nothing to do with this thread.

Um, yeah, so you're being an idiot and doing exactly what a bunch of us repeatedly told people not to do when the idea of tuning these cars first came up.


NEVER USE SOME RANDOM ROM OFF THE INTERNET


You pull your stock ROM and save the damned thing! Then you, or your tuner, start from that stock ROM and make changes to it, and finally flash that modified ROM WHICH CAME FROM YOUR CAR back to the car. Downloading random ROMS from the internet, even if they're "supposed" to be for your car, is just asking for either a blown engine or the kind of problem you have now.


Pull on your big girl panties, suck up the cost, tell a dealer what you did, and have them flash the correct stock ROM for your car back to your ECU, then start over.

I know, I'm an idiot for not saving my stock map. But I didn't know it was that important then, I was a NOOB about tuning at the time. I guess I've gotta go to the dealer and learn the hard way.

This is a really interesting thread. I've got a few questions regarding my WRX(I know wrong forum).
So one of the things I hear about Cobb AP on stg 1 is that it requires more gas to get going (similar to.what was described in op.) My questions are
1.) Is 2013 wrx dbw?
2.) Is this throttle remapping common in tuning; like would Cobb stg 1 smooth out this peddle /torque response?

Thanks

The 2013 is dbw. All wrx from 04+ are dbw AFAIK.

Throttle tuning is common but not always done, necessarily. It only changes feel/driveability not actual engine performance.

i change the throttle map on my 09 2.5i almost every month lol. I have one sportsharp, sport and economy lol. I wish there was a way to install a map switching mechanism like Si drive on my car to switch between throttle maps easier. Laptop and Tactrix is getting too annoying. I know the ECU supports it.

Been reading through this post and looks like the 08 throttle maps are similar to the 06 from the first 2 threads, 08 has throttle angle a, b, c which look almost identical and Requested torque a, b, c, which seem identical and d, e, f which seem idential to each other but different from a, b, c. I've been driving this car for a few years and quess I just got used to the throttle. But after studying the tables it looks like if running off of requested torque a, b, or c when at idle of 800 rmp and depressing the peddle to just 35% = requested torque is 129.6. The throttle blade angle called out for that torque @ 800rpm is 100%!!! I knew it sucked but didn't realize how much.
My big question here is by remapping the throttle how could this affect other fueling maps, mainly tip-in enrichment and accelerator enrichment? If these cars are programed for such drastic throttle movements guessing that these 2 tables might be a little aggressive.

DBW remapping has no effect on tip in. DBW remapping MAY have an effect if there's actually a table in the new cars that enriches off of PEDAL angle rather than throttle angle.

Thanks, after chewing it over I realized that tip In goes off of tps delta. But accelerator runs of of tps %. So as it stands stock. Idle to 35% peddle travel @ 800 rpm = wot + full accelerator enrichment + tip in for that delta of tps. Seems like a lot of fuel being dumped in for no reason! I see how this throttle remap will improve the feel not only from a smoothness standpoint but also from reducing fuel being wasted at low rpm and high throttle blade angles.

drivebywire has effects on transmission behaviour though. shiftpoints, lockup time, etc...

Yeah, I'd love to have access to the TCU ROM just to look at it. It behaves stupidly enough I suspect it's looking at pedal angle, which is just retarded.

Well the throttle remap is going good, I'm much happier with the engine response. The only issue I'm having now is the reason I stopped using the AP in the first place. I have an earlier 2008 MY built in 2007. The ecu likes to rev the idle when clutched in gear and coasting. Revs up to around 2300 and drops to idle and this keeps repeating until I cone to a complete stop or take it out of gear. I brought it to subaru and they reflashed the ecm to stop this, but when I reinstalled the AP this same rev issue came back. Not sure if anyone has a way to stop this or tune it out with accesstuner, I would like some input if anyone on here has this same issue.

I thought this was some sort of assist for shifting /engaging clutch at low speed. If you select a higher gear, it seems to rev higher. It's stupid no matter what.

Ya it's stupid and I quess that is why Subaru patched the software. After I brought it in for that update it stopped doing it, until I reinstalled the AP. That is why I stopped using the AP a few years ago. Now that I'm using it again I want to find out how to either build my maps off of the factory ecm image or see if there is a way to shut it down with the AP.

Is your car supported by the OS tuning stuff? Early 2008 should be. Ditch the AP, start from the base "fixed" ROM Subaru flashed into your car, and retune it for your mods from there. That way, no revving issue.
