i've done multiple 3rd gear pulls running the Stg2+ FMIC agressive map...and haven't experienced any codes. strange....

B_davis · 11-01-2011, 10:02 AM

I use to get 30FF on cobb until I installed a STETT CP w/ forge DVs, it's a boost leak thing

This is what I'm going to try next...I get the P30FF with Cobb but it goes away when I run stock boost. My DV's have 100,000 miles on them, idk if they can "wear out" at all.

I have the ER Charge pipe, and Forge DVs, have run 18+ PSI multiple times with the Procede no issues. And I can build boost just fine where the most boost is happening (2500-5500) no code there, it comes down to when it tapers.. so makes no sense to be a "real" leak.. but I could be wrong.

mithiral67 · 11-01-2011, 11:11 AM

I had no issues with boost leaks on stage 1 and stage 2+ caused me to get a leak at the fmic and chargepipe connection. We are only talking about psi jump of 3-4 psi, but it was enough to cause a connection that was fine to start leaking. I would check all the connections.

nitehawk · 11-01-2011, 11:11 AM

Only datalogs will tell the story...

understood, and before I even emailed them I checked, and re-checked all my FMIC/DVS/Charge connections.. cleaned them from some little blow-by oil. Did a bit of do-diligence and still getting that code (only on 3rd gear) which I find funny.. 4th gear builds more boost 18+ compared to 17, 17.5 on third.. and 4th has no issues so far...

edit: Cobb has a bunch of my logs, and according to them all looks fine there..

Running Stage 2 with Dp's and intake. Since it's gotten colder and moved to Stage 2 (don't know if it's coincidence) I will randomly get a shudder under load with partial throttle. It throws the following codes:
P0303
P2AAF
P29CF
P2C77
P29D9
H2FDB

Service light comes on, I reset the codes, and it runs fine for a while. This has happened 3 times since installing Stage 2. I ran stage 1 for months with no issue and the plugs were changed ~ 1k miles ago. Any ideas?

HPFP

Devas · 11-04-2011, 09:49 AM

Any more updates on stage 1 + FMIC?

Glowin · 11-04-2011, 11:06 AM

How can you tell if it's the stock DV's? How do you test them to see if they're not able to hold the boost?

I'm getting a 30FC (Exhaust fume turbocharger, Density - Turbocharger, boost pressure too low) on the v203 Sport map, when doing a WOT pull in 4th. Didn't get it when doing the pulls on the v301 map...

We are working hard on it! Hopefully we'll have some good maps for you guys in a few weeks!

We'll not exactly, your fuel pump was on its way out and the increased fueling demand just expedited the process. Im at 41K and still on the original pump, i'm curious as to how it will hold up to the fueling demands of stage 2 myself. Hopefully the currently available HPFP will solve the problems, but that's the same thing that gets said everytime a new one shows up lol

That's great news, really looking forward to it.

Devas · 11-04-2011, 12:22 PM

I wonder what the estimated power will be like for stage 1 +FMIC..

At the Cobb meet yesterday they said their Stage 1 535xi (Intercooler only mod) made 328 whp and 402 wtq on their Mustang dyno here in Austin.

And for Stage 2 with required mods only!

So basically a stock car with DP's, running stage 2 maps, so we can tell exactly how much JUST DP's would add in terms of HP.

remington109 · 11-04-2011, 01:50 PM

Ok, so to update my findings from earlier.

I can replicate the shudder issue at will on Stage 2 Aggressive.
Shows the P29CF cylinder 3 misfiring every time

Change it to the Stage 2 Sport...no CEL's

Still think it's the HPFP?

In that case i would lean more towards a coil. Try swapping the coil to a different cylinder and see if the misfire follows it

Thanks. I sent a datalog over to Cobb to see if anything's amiss. I'll swap the coil tonight and see if the problem follows.
Appreciate the input.
