Yeah it nice . Still lacking down low compared to the old setup . Running same boost but is missing quite a bit - can't understand it .

+1 Nice work

When you say missing, do you mean that its miss firing or that its missing what you were use to with the old turbo setup.
If its miss firing, it could be that the D585 coils are not getting enough voltage to them when under that much load at high revs.
I belive the standard wiring ( specifically the main 12v line ) for the coils is not really good enough for high load, its too small for high current load, which the coils may need when you are putting them under that much load.

Anyway that just my two cents.

I meant missing power - feels like it is down around 20whp at same boost in the 3000 to 6000 range . The coils are working fine :)

Brett --did you see that the centerport sleeve doesnt totally seal the rotors from each other?

This could be the timing being pulled. Unless this is after you fixed the knock scale

That was why i was messing with it :) maybe helped a little .......

Brett---there is a hole at the top lip of the centerport sleeve between the sleeve insert and the iron---i started a thread ( with pics!) in the tech thread.
See what you think

FazdaRX_8 04-12-2013 05:49 PM

post a link silly old man :)

Anyone notice that strange blip in the log around 7200 rpms?
The Maf reading takes quite a dip backwards.

I've gotten a couple of logs that do this, at first I thought it was just anomalous data.
Now I'm not so sure, thoughts?

Brettus 04-13-2013 02:14 PM

Yeah , I've seen that often when I use rpm as the x axis instead of time . Not sure what it is but my guess is it is caused by the wheels going over a hump or hollow and suddenly decelerating/accelerating.

Brettus 04-15-2013 02:48 PM

Have run out of injector at 400g/s and 8000rpm

This is with the yellow/yellow/blue = 380+380+480 = 2480cc vs stock 2100

FazdaRX_8 04-15-2013 03:07 PM

time for blue blue blue!

Brettus 04-15-2013 03:21 PM

if i could get some easily i'd do yellow blue blue . But might have to throw some uncapped yellows in there .

FazdaRX_8 04-15-2013 03:52 PM

I am doing fine with mine, the scales just don't work out how you think they would though. I mean mathematically vs real life testing

Yeah - have seen that on other tunes . They usually end up scaled at around 750 to work properly which translates to somewhere around 600ccs.

FazdaRX_8 04-15-2013 04:11 PM

they must be lucky mine are scaled to 608 to get things lined up on my personal tune.

That's the way I like to tune

Um both of those would lean it out....

true . Was just remembering how high your maf readings were and didn't think that through
