That's so me ...

[iuhutch]

The turbo is in and she now has 48 miles on her with no hiccups at all! The install ended up taking us about 9 hrs and that was between not being able to get the damn turbo out through the engine bay and having an accidental removal of an A/C line (to open more room up to get the turbo out from under the engine bay), the install itself wasn't too bad. Coolant was annoying as it was definitely dripped out of every tube possible. All and all totally worth the groupbuy to get this upgrade!


The car is an absolute beast now. Havent gone too crazy with her yet as wanting to settle the changes in; also seeing some adoption in the logs, is this expected? Between my first 17psi pull and the now 19 psi peak, afr, timing, smoothness of boost and rpm curves all seem to be smoothing out.

My biggest concern is that the ecu is only seeing 4.8psi of boost and this scares me with the DCT?

Second call out (not really a concern) is that I'm only holding ~13psi at 6,200+ rpms? I'm barely holding 15 at 6k flat. Still WAY better than the original snail but per some other logs, this seems to be a bit lower?

Using map 6, I played with the PID gain (from 25 to 10) and upped the higher rpm targets to 17 but haven't change much else yet tuning wise. Would love to hear thought from others that have had this turbo and running map 6 a bit longer if there is a better config than the below. Also attaching logs too.

I own a android phone so reading your csv file is hard. 1st question. What map is this on? That boost curve looks like map 7 boost curve which is really weird.

[iuhutch]

Read a bit more on n54 and noticed T didnt mess with map 6 on the ewg pure setup.

The previous post above was an old map 6.

Had to go for one more quick ride trying map 7 and then map 6 again. Per my thought earlier, the engine seems to be adapting quickly. Overall pulls are starting to feel less jerky and more responsive on the top end.

I'm having an issue with my .csv's? Keeps saying invalid file when I try to upload WTF?

[JETmn]

Did you do a boost leak test after the install? I think it looks like you have a boost leak. It is falling off hard around 6k.

[iuhutch]

Not sure it's a boost leak. I'll double check the hot side of the fmic tho. My thought was potential opening Of the plastic DV? Also another thought I had was a lb or two of pressure loss through 7" fmic? Also seems to be holding it more the more I run it.

[JETmn]

Bigger FMIC will be less loss if the construction inside is equal. I think you have the VRSF, right? That one doesn't seem to have much loss to it.

7" fmic's usually have a ton of pressure drop... From what I've seen and read even the vrsf 5" has a significant amount of pressure drop. Prob why it's one of the cheaper ones on the market.

[PeterPure]

If your pwm is at 100 or close to it then the turbo wont give more boost.

My stock fmic does 18 psi at 6k and 17 psi at 6.5k.

The forge fmic did 15.5 psi at 6k and 14.5 psi at 6.5k. And its a small fmic.

My wagner fmic does close to 18 psi at 6k and 16.5 psi at 6.5k.

My bet is that its your huge 7" fmic. Put stock fmic on and retest.

You can always mail me your csv and i have a look.

Tnx,
Peter

There is definitely something wrong. My car didnt necessarily have to "adapt" so much to hit its new boost targets. After the first pull car was seeing 18-17psi at 6k and 16-15psi at 6500rpm

I'll check my hot side intercooler piping but my only thought would be the stock DV is potentially cracking open?

You have the forged, right? Can you post the 16psi 6500rpms please!

In 4th gear, I'm holding 14psi at >6k. I think it's all tuning related would love for PURE to chime in on their thoughts too! Car feels amazing tho

I doubt its tuning we all have Jb4 that run the stage 1 turbo and all see 18-16psi at 6k even e36addict whose logs show slightly bellow target shows higher boost than you. I have a helix fmic which I think its 4.5" or 5 I dont recall.

[paradoxical3]

Any shipping update?

[1cleann55]

You know what I think your problem is I think youre setting you boost targets wrong or too low. Either I need my glasses or it seems like you have to high targets midrange and immediately lower them to low uptop. Your boost target settings should look a little like what I posted up a few pages back

Turbo should arrive tomorrow. Also, received my flex fuel wires for JB4. I have a Cobb for a back end flash. Ordered an AA FMIC so that should I arrive this week. Might have the FMIC and turbo installed at the same time.

I have an AA FMIC on the way. Still hesitant to do intake and downpipe due to warranty and noise (I have a good audio system). I'm willing to use lower boost levels until I get around to doing intake and downpipe.

Without downpipe this turbo is useless no offense. Max boost you'll probably be able to safely run is 13psi across if that. Not saying you can't run 16-19psi with a stock downpipe the issue is that the back pressure will literally blow the turbo up.

Thanks - no offense taken. I understand the physics of the situation. My hope was to improve the high end of the rev range with just the turbo. Once I have my Vanos bolts re-done by the dealer, I'll look into a DP.

No it won't LOL

Ok I have to say, that is garbage. Please show me any evidence that not having a catless downpipe will blow up your turbo when running higher psi. Yes, having the dp will help lower back pressure and spool quicker. But you will not blow up the turbo if you have a stock downpipe. It is just insane to think that.
