I just installed the AP and cobb is sending me a new vaccum line to replace the line with the secondary restrictor pill in it. Right now I dont have a boost gauge (which I should be getting one in like a week) but I know I'm not hitting target boost with the stock boost line. Does anyone know how much you will useually under boost with still having the stock restrictor pill in there given I dont have any leaks or anything? I guess the reason I ask is because right now I feel like I wasted my money because my butt dyno is not too happy with the gains or lack there of so far. It feels about the same as it did untuned with a tbe and intake. So has anyone seen the difference first hand from going from stock pill to no restrictor pill on the stage 2 93oct map? Thanks for the replies sorry for the lengthy post

 

I don't think your boost will be lower with the restrictor pill still in. I think they have you remove it to control boost taper. At least that's what I think they said is the reason for removing it.

I haven't seen much of a gain from my flash either.

 

Pretty interesting chat.......

stage 2 91oct here in AZ at High Elevation.........took my evo from "i'm used to the power and bored now........to I love this car again!!!!!!

AKA...my car totally changed.........to not see any gains or little gains from these flashes then either there are leaks (which I think you have both said they are none), or the lines aren't on right or somthing.

Not only was my secondary pill taken out....which at that point with just that pill out still the gain were very little....it wasn't until Stephen at IA Performance took out the main pill....redrilled it a different size did the car come to life the way the new maps said it should......

My car went from let say the averages of 242 hp/tq (mustang) stock to 289tq & 285 hp on stage 2 91oct.

The gains are there.....everything just needs to be re-evaluated....now since I am a mechanically inclined idiot I take my car to people that know what they are doing....not to say either of you don't but maybe you should take it to a shop nearby and get another set of eyes on it

Just my take

Good Luck Guys

 

CPA5,
You're correct. There should be a noticeable gain from the flash or something's probably wrong. But I think you left out one option: The AccessPort itself.

When I had my 1st Evo flashed (by Dynoflash) I didn't even need to do my normal testing to know my power had increased. The car "felt" 500 pounds lighter the first time I trounced on it. When I then tested it on one of my testing grounds (an onramp) my speed went from 80 to 86mph. (I had a 3" TBE on it previously. No gains seen from TBE until the flash). The flash was for 91 octane btw.

My new Evo did the onramp test at 81mph when stock. After the AP flash it was 82mph...at most. (93 octane flash)

I eventually tried the 91 octane map thinking the 93 map was screwed up. The car boosted about 1.5psi over the 93 map peak boost. One of the guys from Cobb said that was weird because the 91 map is more conservative (should be lower, not higher if anything).

I know flashes work, but in this case it's not working enough. I asked Cobb if they knew any shops near me to take my car to and they gave me a name. I haven't called them yet (it's two hours away) and I thought I'd wait until I get an answer to my "Boost fluctuates" thread. I'm wondering if I created a boost leak when installing the new vacuum lines. But maybe an answer to that will explain something about my lack of new power from the flash too. The stock lines with the restrictor pill removed held boost just fine.

As far as being mechanically inclined, same here. That's why I asked a friend to come over.

 

I agree....it could be something with the AP or maybe the maps loaded on it originally....my memory isn't that great...but I thought you were one of the individuals that needed the new 93oct map because of idle issues ....

One thing is for sure...COBB will make it right by you and help it get resolved.

Hopefully allot of these issues will be non existent to the AP users who want that custom tune.....I am waiting on that then I'll put on a boost hose line I got from GST Motorsports and have a go at it.....of course I bought that boost hose line prior to COBB giving them out for free.

Once again I hope you get to the bottom of it

 

I dont know of any shops around where I live that tune with it but i've felt little to no gain from mine what so ever I fell like I wasted my money and I could have just drove somwhere and got tuned for the amount I spent on this thing. On my subaru the gains were very noticable. I'm not really sure what else to do.

 

CPA5,
No, that wasn't me. I'm at stage 1 93. I think the idle problem was stage 2 93.

I see you bumped my boost fluctuates threads. Thanks.

ethompson,

I feel the same way at the moment, but you know a flash worked on your Subaru and I know a flash worked on my previous Evo so I'm sure it's just a temporary glitch for us because this is nothing more than a (expensive) flashing device.

 

When I flashed the stage 1 i felt the same way, didnt feel the power gain but only noticed that boost was smoother. The Stage 2 gained way more power but thats with the TBE and intake.

 

ethompson--

I would think that the stage 1 gains aren't going to completely transform the car as much as stage 2 does.

when we did the install on my car IA dyno'd stock vs. stage 1 vs. stage 2 ........stage 1 only seemed to smooth things out much better than stock and the gains were like 10-15 each if I remember correctly...maybe a little more.

I'm sure that COBB wouldn't create a stage 1 map that does absolutely nothing...you should feel a little more power and definitely it should be a smoother delivery of the overall stock set-up.......I would be on the phone with them ASAP to get it resolved.....I still think something is not mechanically correct with the car or the AP....cause you should be noticing something.

Remember the AP is more than just a device to flash with.... there is the live data, check engine codes, performance time readouts.....it does more things that I would assume you bought it for besides just getting a flash out it.

Good Luck in getting this resolved!!!

 

Well that is the thing I AM running a stage 2 93 oct map currently and yes the tq curve feels smoother but not that much stronger. With my subaru the gains seemed much more noticable with the stage 2 map anyway I dont know though I should be removing the 2nd restrictor pill in a day or so and going from there I am also getting a boost gauge installed to make sure I hitting about what I should be. thanks for the insight though

 

CPA5,

The stage 1 93 map is supposed to net a huge gain; 17%. Stage 2 93 is supposed to up that to 24%.

 

Just so I understand....so far AP is uploaded on stg2 93 and you have left the original boost lines intact?....so no restrictor pills have been touched at all....is that correct?

If that is the case I would assume that since COBB made the maps with that 2nd pill completely out that that must be why it feels lackluster compared to how it should be.

Earlier you said that COBB was sending you a new line...have you got that yet?....Cause I would just wait until then and just swap lines and don't even bother with taking out the 2nd pill

 

It may say that on the website....but we didn't see the exact gains with my car as per each level stage.....I think maybe all that talk about each car is little different could be true...but who knows Im a car idiot....

And just to clarify If COBB says it should gain that much then it should at least come close....I think that my car didn't hit the % gain on HP that was claimed...it came close...but it actually did exceed the % gain on the tq side.

once again maybe each car is smidgens different and that matters

but if the gains are marginal at best I would still think something has to be amiss somewhere in the setup process...either car or AP....cause I can't imagine that some EVOs will respond absolutely positive to the base flashes and others not at all

So...anyways have you guys been in contact with them further and working on trying to troubleshoot this stuff to get resolution?

 

Damn. I just lost everything I wrote by minimizing this window for a few minutes while I did something else so I'm going to just make this a short answer this time.

Done with troubleshooting with Cobb. I plan on taking it to a shop they recommended.

 

Yes I have the stage 2 93 oct map loaded right now with the stock lines still in place. The other line that cobb is ending me should be here by tommorrow and ill be switching it out then. I hoping I will see a bigger difference after that
