AP Map
 

Ive had an AP for about 3 weeks now and the only map that works for my car is the 91oct Stage 2 v130. Every other map that I tried makes the car run like crap. My mods are a catless TBE, drop in K&N and an hks ssqv. Have any of you been using a better map for this setup?

Make sure you are using a Cobb-supplied map that is meant for a catless TBE and stock intake. If you have any that didn't come from Cobb, toss 'em. The exception would come from any custom tunes you had, but of course if you had one you wouldn't be having issues. ;)

That sounds like the correct map. If you read the readme file for it, it should say exactly what the requirements are for that map.

If I recall correctly, stage 2 is TBE.

However being catless may have even less than expected back pressure. I would suggest you do whatever you plan if anything for the intake, and then get a custom tune. You might also consider putting back on the stock BOV as I believe the HKS is a vent to atmosphere which is not ideal for Subaarus.

Kevin how would he have a map on his AP that was'nt from Cobb unless he had a protune!
And he could have a protune and still have issues! Stick to the nonturbo advice ;)

Actually the person I bought the Cobb AP from had a bunch of STX, chronos, and PDX maps on it. Some were made for 92 octane. ;)

Dean is right the off the self map is for there catted TBE and stock air box! You need a fuel pump and a protune for the car to work poperly!

Apparently, the previous owner found a way to put non-Cobb maps on there...

You should never use a map that was not tuned for car and sorry Kevein I for that factor of the used AP!!

Used or not, you can get non-Cobb maps for them. But no worries, I don't have to go to the moon to know it isn't made of cheese. ;)

Speaking of which there is a picture of the AP on the COBB sight!

Has someone hacked the software :?:

The only reason I tried the other maps is because the guy I bought it from had the same setup as me, the difference was the 92 octane. which I guess I can get in town here at the gas station on longley and colbert if I become a member.

Does anyone in town here have a TBE catless map they could send me?

I ran Cobb's Stage 2 91 Cali map on my catless Stage 2 with an HKS SSQV on my car for a year and a half. It ran like a champ the whole time. You can download that one off the cobb website. Maybe it's the intake thats throwing it out of wack.

It might have felt fine but If you threw on the dyno Im pretty sure it was'nt with out a fuel pump!

I never said my car is running like crap and I dont have an intake. My car runs really good. I was mainly asking if there was a better map for my setup. This thread took a quick turn left somewhere.

Eric, any ProTune map for the right ECU can be downloaded to the AP and then flashed to the car. That is how a custom tune gets there. And people are sharing their ProTune maps on different web sites.

That said, I would not use anything other than the Cobb maps which are very conservatively mapped, or one built for my configuration.

Anything from other sources is a crap shoot that might cost you an engine. No thanks.

And it sounds like the COBB 91 Octane stage 2 map is working fine, so why are you looking for another map? Without a custom tune, I wouldn't push it past that map, and as I said, that map may even be a problem without a cat. But hey, at least it works.

Stock turbo WRXs did okay without an upgraded fuel pump. Peak power is a bit lower but you can tune them safely.

Welcome to SECCS. :lol:

Werd.

I agree with Kevin and Dean. Stick with the Canned CA91 stage 2 map from Cobb, or better yet, get Protuned.

I'd never heard that an upgraded fuel pump is a viable power mod for a stage 2 WRX (stock turbo). Would you want to get re-tuned for it?

Dean and Kevin got it right. I read your post a little to early in the morning. I'm of to go get a fuel pump!

Yes. A bigger pump won't throw off your current tune, but it will enable you to run more boost and/or timing from your torque peak and up in the power band by permitting richer AFRs and/or supporting an increase in VE through other means, such as boost.

Interesting.

Remember, the max flow rate for an injector depends on several variables- max duty cycle, gamma on time, and fuel pressure. Injectors are like the spray nozzle on a garden hose. Max flow is determined by how fast you can squeeze it off and on, how big the hole is, and how much water pressure you have. If the faucet is only turned on halfway, you get less flow than if it's all the way on, even though you are opening the same nozzle with the same frequency and duration.

Stock fuel pump = faucet half open.
