Hey man,
That log was waay too long. Can you shorten down your logs to just a WOT 3rd to 4th gear pull and start your pull around 2000 rpms to 5500 rpms. Searching through all that data is too much effort for me, lol. 19 counts of knock is high but I want to see if it is consistent.

 

Also, I wouldn't' be running the 93 map. Run on the 91 map and if you are still seeing crazy knock, run the ACN 91.

 

Lol, my bad. kinda new to this . just did this log about 15 min ago. started as you said in 2k r.p.m in 3rd gear shifting to fourth @ 5.5k r.p.m all the way till redline. I think it looks better now, but not sure about the knocks still seemed high. btw this was still on the 93oct. betamap. using Q.T. 93oct gasoline. Thanks for the reply RAPTR.

you need to configure the logger to log the items we need

rpm
load
boost
knock
ignition timing
wdgc corr
ltft used
MAF V
IDC (injector duty cycle)

then drive around a bit (20 min) @ cruising speeds logging
then end the log and re log a few 2000-7000 pulls in 3rd gear

 

Curious why you're suggesting the 91 ACN map for him when he's burning 93 in the tank.

 

all acn maps are just slightly less timing and a lil bit more fuel
4th gear pulls in 100° heat are most likely going to knock a bit

 

Since '11 GSRs make 27 PSI on Stage 1, and I would imagine Stage 2 would have similar targets, too, do you guys think an FMIC would help more to '11 models than the previous year GSRs with Stage 2?

Speaking of which, why does Cobb not have OTS maps for FMIC? Is it because Stage 2 OTS should work, or is it because Cobb does not believe in any gains by FMICs (which might b true anyway)?

 

^^ this

 

Typically the stage 1 map will Work on stage 2 cars and just make more boost (2-3psi max) Some wont make that much boost.

I start all (stock turbo /inj) cars out on the EXACT same map and tweak from there. Once i make stage 2 maps for 2011 there will be some more happy people.

 

I wasn't asking about that at all, though

Fmic dont do much except cool air better maybe flow a psi or more.
10-15 whp max no need to "tune" for them

 

Great, thanks for the reply! This is what I was suspecting, too and thanks for confirming it from your experience. Companies that sell FMICs show untuned EVO numbers with intake + FMIC installed, which is clearly very misleading, and I personally believe it is borderline 'false advertising'.

A few friends and I came to a conclusion that in real driving conditions (read a lot of wind), stock FMIC is adequate for the stock turbo, and there's no need for an aftermarket FMIC; would you agree?

What I'm personally thinking is maybe just changing the intercooler piping, and that's it as long as I stick with the stock turbo.

 

I would love to see what kind of gains are achievable after tune since that power difference might be a result of the changed variables, leaned conditions ..etc..
maybe Cobb didn't offer any maps for the FMIC for the very same " no gains after tune"..

 

I asked the very same question over and over again. The reply was "No, it makes about same". I looked at all '11 results for GSR's at Cobb's dyno results library, and what I see is, yes, they make similar numbers, but all dyno runs (including OTS maps and Cobb's Stage 2) also make only 24 - 25 PSI max! We all know that at least Stage 1 OTS map makes ~27 PSI, and when Stage 2 gets released, it should do the same, too, if not more.

It makes me wonder: Perhaps Cobb's dyno does not generate load numbers similar to what we get on road, so it never made ~27 PSI on the dyno and they only saw those boost values on the road? After all, I don't see any dyno result whatsoever with the boost values we see on our cars. I am fairly confident we should be making substantially more than the 290whp cars make on the syno at 24.5 PSI.

FYI, I hit 26/27 range on all 3rd, 4th, and 5th gears, so it doesn't require much load to do so. It does about 25 PSI on second as far as I remember.

The results below all make < 25 PSI. Stage 1 does only 23 PSI max to reach that 290 whp / 301 wtq:

 

Sometimes cars make more boost than others :-p
Also, a slight spike to 27 is not the same as holding 24 for 2000 RpM

Sometimes the "peak" you see is just a quick blip.

Regardless i have tuned the 2011 basemaps from 24-28psi so whatever it runs its AOK !!! The 2011 Maps i have also include some boost pill maps (not released yet)
that run 28 psi from 3000-5500/6000 and drops to like 22
Thos e maps run the same timing and fuel maps as the regular basemaps the boost is just different
