I just had the ECU reflashed by RSW yesterday (the dealer wiped out my old map when installing Sirius) ALl I can say is... WOW! The tune is more aggressive. I am seeing 20psi on Map B. I haven't flipped it over to Map C yet. Will try that today. Here are the logs for each parameter with a 4th gear pull at redline:
Timing - 11 deg
AFR - 12
Ambient temp - 70
IAT - 84
Boost - 20psi
this is on a K04 turbo and the rest of the mods are listed in my sig.

Combination of more boost, humidity and fmic that doesn't seem to be performing to spec. Before the spray I was pushing 40deg above ambient at 20+ psi. The spray has been great so far.
#756
I'm curious as to why your FMIC isn't performing up to spec. I was thinking of going with the Tyrolsport FMIC myself. Is it build quality that is making it underperform, was it damaged somehow, etc? It's a pretty-penny for those and it's a shame yours isn't working that well.

but isn't IAT measured after the IC but before the turbo? granted, i don't live in humid conditions and i'm not tuned, but i was seeing IATs at 3° above ambient consistently, as long as the car was in motion. this is stock car with a black alta fmic.

Mario, You may be right. I really don't know for sure how well this IC performs. I never had the opportunity to test it against stock or another IC. What I see is other IC's (helix) that seem to run cooler IAT at similar situations. Don't really know for sure because there are so many variables. The only real way for me to find out is to buy another FMIC but I'm not willing to do so. I'll run another smaller jet perturbo before I do that.

IAT is measure after IC and before intake mani. IAT is not measured before the turbo. Not sure what kind of driving conditions and load you are running at 3deg above ambient. At stock psi levels and redline, I was seeing 6-20 deg above ambient before I hooked up the spray. It varies with the weather. Now with more boost, those temps climb significantly.
#762
3°F above ambient is typical for cruising and NOT in boost.
Typical IATs for stock configurations while in boost is 20°F - 40°F above ambient after the intercooler. Aftermarket intercoolers generally give 10°F - 20°F above ambient while in boost.
#763
I was referring to EGT, just to give an example of how hot the turbos can get

So I have been running mode C on stage 2 for the past week or so. I recently swapped out my Forge atmospheric BOV with a Forge recirc valve from Forge. I was getting a couple of fault codes from the car looking for the air that was being dumped into the atmosphere versus being recirculated into the system. My main reason for doing this was to get rid of thee fault codes but the more I read, I realized the atmospheric valve was causing the car to run rich as the ECU was looking for the missing air.
The temps dropped dramatically here in Texas overnight and I have to say with the colder air, high 50s and the new recirc valve, mode C is crazy. Car feels amazing. I am looking to schedule some dyno time but I need to find an AWD dyno.

With the KO4 at 20 psi you should be moving 30 lbs/min at a pressure ratio of 2.6. That puts you in the 74% efficiency island on the E45R. Crunching the number puts the air temp out of the turbo at 232 degrees. Your temperature drops is 232-84=148 degrees. Another way to look at it is your 14 degree over ambient at 22 psi (considering a 2 psi drop across the intercooler) so yep I'd say your intercooler is working fine. BTW the ECU doesn't pull timing till IAT is over 100.

I have been playing with Map C. The tune is just a bit more aggressive than map B and sure does rip on the highway. Heres what I was averaging on the Log at/near redline:
Timing - 12 deg
AFR - 12
Ambient temp - 82
IAT - 97
Boost - 21.5psi
The spray seems be doing well with respect to fuel. I don't see any loss. I am running 350cc/min. I may add more volume for the purpose of cooling though.

This is from a countryman page on FB. This guys is supposedly running a Manic tune with aftermarket turbo. Playing with fire in my opinion. Only a matter of time before boom, pop.

It also looks as though he's running headlong into a wall at that boost. Yes, I kid. But boost this high on pump gas is certainly going to cause knock and detonation. And even if running very high octane, I'd suspect this is too much airflow for the stock connecting rods to bear.
#772
I would hope he is running meth or race gas on map C.

Those damn weak rods. I know it's a reality, but like most of us, we just hope it won't happen to us. I did blow my modded R53 twice, so its always at the back of my mind
