the commissar!

That is real car love

My EGT begins to climb when I go above the 12.4 AFR mark too but unless I have timing way low or am running too lean AND high load, they don't get crazy high. I'm measuring pre-turbo so I guess there is maybe +150-200F difference? What kind of peaks do you see? Your car is so amazing! I love "tuning in" to your threads to see what you are working on...Those new headers are sweet looking, I hope they net you something substantial beyond the obvious cool factor.

What does your EGT look like when your AFR is that rich...I know our builds are miles apart but mine climb below low 12's and if I get in the low 11's or high 10's they skyrocket. 12.2 to 12.4 seems to be the sweet spot for me, at least as far as controlling EGT.

When I say lopey I'm not talking 60/70's era muscle car lopey, I mean that you can hear a slight change in the pitch of the exhaust tone and it sort of sing-songs up and down...the RPM is steady to where it is undetectable if it is changing on the dash gauge...It was not sing-song like that with the Volvo T5 stock tune...or maybe I couldn't hear it with the stock exhaust, that seems like so long ago... I started with the base performance maps and until recently didn't realize they were different...not sure why they would not have them standardized to begin with. Adjustable sure but they should have started the same...I sense some more laptop time in my near future... I'll get things sorted out as much as I can first and once I get a way to log my timing along with the other, I'll share for input...I can't log that at the moment...and once you pass a certain point, you have to play with timing and I, like you need to see and record exactly what it is doing. The butt only takes you so far in tuning and I'm past that...

You got me on the overlap vs vacuum...I think it is harder to figure than it first appears due to exhaust back pressure and back filling cylinders etc...gives me a headache when I think about it My idle has been lopey since I got TT, same with running rich at WOT. I think I can fix the running rich in the fuel maps but not sure about the lopey idle...could it be that the ECU can't decide which block it wants to be in making it bounce around since each of the three maps are layed out on a different grid of load x RPM ?

Did you ever figure out what stock setting for turbos are? I recently (Friday) moved from EX +4(IPD) IN +3(IPD to EX +2.5(IPD) IN +2.5 (IPD) It helped smooth the power band out with the most recent revision to my TT maps. Peeking at those you posted here last week helped a lot with the ignition maps...Thanks! I do miss the raw power down low that the more advanced settings had...maybe when I get the insides beefed up I can go back...for now, my tires will last longer ;)

I feel your pain H, I am going through the same type problems trying to tune mine but at a MUCH slower pace...If I had one TT wish it would be map-trace log...It would be interesting to see your maps although I am only at ~18+psi peak on an 18T. And my goal is not necessarily high peak power but more usable low and mid-range power since this car is first and foremost a street car that's daily driven.

I'm running 18 psi on my 18T with stock internals (for now). Im running a Hallman Pro MBC in parallel to an IPD HD-TCV to help keep me out of trouble. I've been tweaking the fuel map but am not satisfied with it yet. I'm afraid to just romp on her but I rarely see >12 psi under 3600 rpm. I probably would if I just floored it but I want to keep her in great running order so I ease into high boost. Using base performance ignition timing map and it seems quite good so far. I'm interested to hear more about your (and everyone elses) TT adventures.

Consider that there are a number of different definitions for socialist forms of government (traditional) and the definition is a moving target. I never said Obama or his administration are socialist, but it is undeniable that this administration's policies, and other historical administrations policies both Democrat and Republican) are pushing the country towards socialism. Any time they begin to infringe upon citizens rights or get involved in capitalistic ventures, they nibble away at what makes America great and moves us toward a more socialistic type government. Modern Socialism. Trends toward Modern Socialism include: Infringing on the constitutional rights of citizens Interfering in capital markets widening gap on "acceptable" property takings / eminent domain interfering in individual businesses and industries and anything done with a Robin Hood mentality of take from the haves and give to the have nots in the interest of "fairness and equality"

The only bigotry and hatred is for people too lazy to help themselves to anything but the Government pie handouts! This is not about race, or sex, or national origin, or religion, or handicap, it is about responsibility to ourselves and each other.

The Tea Party is not make believe. But it is also not a "political party". It is a grass roots association of like-minded individuals with no leader, who believe that government is too big, socialism is wrong, and the law of the land should be based solely on the amended constitution of the United States. With core values of Fiscal Responsibility, Constitutionally Limited Government and Free Markets, Tea Party Patriots are conservative in nature but not closely aligned with the Republican Party. Needless to say they are not liberals or Democrats in any way. How can anyone support either republicans or democrats? These fools are converting our country to socialism and bankrupting her at the same time??? If you personally spend more than you make what happens??? Should our government be allowed to continue this trend to the ruine of our country??? Think about it... Maybe you should be a Patriot
