More downpipe troubles

[FreePenguin]

On phone right now. I talked to them a lot in past when I was doing the Cobb stuff. nice guys

Cobb just said, they discontinued their downpipes, and removed all the stage 3 tunes, due to CARB EO. he said that just now. pulled all stage 3. he said, even if you find stage 3 on the internet due to the Cobb access port update, there's a strong chance, it will be greyed out and unable to be used. (the update should of nulled it) but he said there's a slim chance it may work.

cobb stage 3, peaks 26psi, and tapered down to 20psi. so 24.5 stage 2, and stage 3 was 26psi

he said, it was immediately after the carb stuff was pushed, he said the company made us yank the downpipe, and the tunes immediately. he said they "may" come back with a new revised downpipe, but he said its doubtful, too much heat.

do not update your Cobb access port, you will lose that stuff. and I think the tunes you get, will also lose certain capabilities to alter things. I wouldn't chance it.

Oh wow. Good thing it's been like a month since I updated it. Lol. Welp. Guess I'm running with the S3 that no longer exists lol.
Looks like I need to find a tuner.

yep, a lot of pissed off people on Mustang EcoBoost forums updated, there was no notes. it altered the current maps, etc. people do believe they reduced power a bit, prob pulled back the power to meet closer emission specs. they can only guess but they are probably smart enough to do so pretty quickly on 2 maps per car. otherwise they wouldn't of updated. and if you was reliant on stage 1/2/3 maps. can you imagine how mad you'd be to log in and find out your tune is gone, so you cant reflash back to it if you changed?

yep. quite a lot mad.

here on out, ford etc will make $$ on future performance pack upgrades since they will be the only ones honestly EO certified. ie ford perf tune, which is equal to like stage 1 on Cobb.

Man that would suck. Thankfully I'm lazy and I barely take my AP out of my car. It's usually plugged in all the time. Well I guess that helps local tuners lol. More Business. I wish ford would pro tune.

if it isn't eo certified, they would never touch it. it takes them like 2 years to get the ford perf tunes released and they are a big $$ fish.

Yeah I hate taking my car to ford because of the cost. I had my ac compressor go out and they wanted 2k for everything. Lol.
That's why I do everything myself. Jeez.
Well it sucks I have to go spend a lot more money to get the car running amazing but I guess it will be worth it.

your case though intrigues me, it sounds like that very first boost, hit its target, of 25psi or whatever. then it never did it again.

now you are getting less boost entirely. dont rule it out, just double check the end clamps on both hot and charge pipes, make sure nothing may of gotten loose or maybe pushed back a little from the higher boost. tighten them a hair if not. then try again.

check the oar im sure you know its already -1.00 and the car is fully warmed up and in the green on the dash temp.

Yeah to be honest when I felt the loss of power the first time I put the DP in the first thing I checked were the chare pipes and all of the possible air flow areas. All the hose clamps and everything are tight and flush.
S3 has never hit it's mark I don't believe. S2 hit it's mark and it also over boosted once.
What's weird is the DP is meant to increase power if anything and I'm losing power lol. But I think it's because of that boost not hitting target. I'm pulling close to est. Hp and tq on the new DP with Les boost. So if It actually hit peak boost I should see the gains I'm dying to see lol

 

[FreePenguin]

no, you should be hitting higher boost. you didn't lose any power with DP. look at the chart, the torque comes harder than any previously. something is a miss with yours. its not reaching its target, which means its struggling to get to it.

drop down to 1/2 what you was at before, and try to replicate. if it hits those targets "easier" and holds them, then im curious, but it may also be stuck at the same levels, meaning a small boost leak

Have you tried flashing the stage 2 tune back on? I may have missed that along the way.

Nah I briefly went to stage two for a couple of days. It was acting kind of strange but so was stage 3. Mainly because the DP wasn't seated right. My brother said to try stage 2 again and see but it's a lot of work for the ecu to relearn the new tunes. So It would be hard to see if it's running great until I give it some time to learn.

I get what your saying about a leak but every other stage reached peak boost and I didn't change anything. I didn't mess with the turbo or anything. I just reseated the downpipe. But before and after reseating the DP I wasn't reaching over 20lbs on stage 3

KAM reset. disconnect both battery red and negative terminal, touch them together a couple times (not to battery) but too themselves, leave battery disconnected for a few minutes, like 10, touch them 1-2 more times to discharge any possible voltage left. I also turn my headlight on when I did it, just to make sure sucker was dead dead.

anyway, then reconnect battery.

car will be slow as fuck for a day, dont romp on it, just drive it around as you would. it'll relearn all the octane, and relearn all the new map fuel trims.

its a CLEAN slate for your car. just like factory, it isn't actually factory, but it will be relearning alllll the fuel trims. takes a day or two to fully do. I did it, and it ran so much better. I will do this each time I do a major service., ie like changing plugs every 50k etc. or major mod change. which im done with now.

I think you will lose your FM presets though, downfall. Lol

 

[FreePenguin]

it fixes a LOT of peoples issues with stuff.
After I went back to OEM downpipe it was running like shit, I had to do a KAM reset, and it fixed my issue. it was running the fuel trims learned from when I had a aftermarket downpipe etc. by resetting it, with the new mods, it lets it learn the correct adjustments without altering old ones.

 

[CorvZ061]

You can do a KAM reset from the AP, it's faster and easier. I would for sure flash back to stage 2 and drive it a little, see if you're still getting boost like you expect and have gotten on that tune previously. That'll narrow it down to being a tune issue or a boost leak.
