Just came back from a 750 mile round trip to visit ynot411...it was pretty cool but too bad I couldn't slam on it on the interstate cuz I have no hood pins for my CF hood...oh yeah I only mustered a 25.5 mpg @ 75mph totally cruising... oh well...lets get to the dynos!

Car: Steven88's 2k2 Nissan Maxima 6spd 46k miles
Mods: Berk/Apex-i, Cattman Headers, Budget Testpipe, Cattman Bpipe, Stock Muffler, V-AFCII


This is run file #6...I don't have the files with me...I just printed this one out for now...ynot411 will pick up the files later on this week...but this is my 6th run and I'm already at 245whp with room for improvement....my baseline (very first run without touching anything) was actually 240whp....



This is another run thats worth printing out...it's actually my last run of the day at 35....the AFR is a little flatter...I can't directly compare 6 and 35 cuz I dont have the run files...but I can say for sure, I know run 35 would score a higher whp than run 6's 245whp...but since run 35 my engine was majorly tired out, it only mustered out a 243whp....I'm thinkin 248/250 whp & wtq with a cool engine and run 35's AFR (my current setting on the AFC)...

Overall i'm happy...I wasn't expecting these #'s especially with the stock exhaust....I sold my cattman to Maxboost925 (hope you enjoy it)....thanks to ynot411 for the tuning....but damn, you killed my wallet driving up here .....He should step in here soon enough to upload his print outs and run files...Enjoy!

 

Nice andrew........ maybe i can get up there when i get some money...

 

Those are some damn nice numbers... I'm curious to see what the AF looked like before tuning as well. Did you do the tuning yourself? When you get those run files, you know what my email is...

 

ynot411 did the tuning....it took us so freakin long to get the AFR right becuz the sniffer was screwing around with us....like it was off by a certain margin...we didn't realize it until later....man my car took a serious beating that afternoon

my baseline was actually lean...pretty weird but I thought I was actually running rich.... guess I was wrong

dynoing is pretty fun! I think I'mma call some local shops around here and see if I can do some tuning for cheap....

 

uhh.... nice andrew...iam really happy that u got everything to work out well after 35 trys lol....iam very happy...
and bout' that CF hood, since u dont have hood pins...we can make a deal (i'll trade you for my OEM one) lol j/k
good luck man...

haha thanks huso....damn u shoulda been there watching me dyno...even with a stock muffler, that **** was LOUD as heck at WOT....I mean everybody at the shop was just like ....and so did other vistors who came...

Man the pull on this car is amazing now....I can definitely feel a nice as he!! mid-range gain....

 

did u get ur front lip yet?

 

Nice work man, gives me something to look forward to.

 

No front lip, i'm waiting for ionic dynamics to come out with their CF MT style front lip

 

teh cattmang = in my garage waiting to be installed tomorrow. jack it up high y0!

 

when I took it off, it was a pain cuz you had to keep wiggling it....that little "cave" the piping has to go thru will be a bizzitch!

 

lol, I'm assuming b-pipe will be easy?

 

oh yeah, bpipe is easier IMO....theres nothing really blocking the exhaust from dropping down...

 

Those are some really strong numbers.. I really need to get tuning!

 

What he said, still waiting on 6th gen headers before I pick up an safcII.

 

Why are you guys getting SAFCII when a VAFCII has twice the adjustment points.

 

i dunno? Maybe they are able to buy it used for mad cheaps...thats why they gonna go with the S-AFCII route....

 

I was just speaking in general. Last time I made the statement about the VAFCII being more benificial and stated the reasons the dude called BS and then his buddies came around the thread talking crap saying I was wrong.

 

I tuned the day after steven88 did. See scanned in graph below. Not as nice as steven88's but good enough.



In addition the fuel curve is not as nice because the car was cooled for about 30 mins. before the run. That is the reason for the jagged power/tq curve. However, it is my best Max Power/Tq so far.

 

I believe you were right in that thread and that "dude" and his idiot friend got pwn3d by a few others before the thread got deleted.

 

haha, dat foo got pwn3d bad....whats so hard to understand that you can wire up the V-AFCII to any car....just don't use the vtec wire and your str8....people these days

 

So um, I'm gonna get like more exhaust parts and pwn you all

 

Numbers look good

 

You need to fix the vacuum lines on your VI. It isn't working.

Also, you need to set your A/F to about 13.5:1 or close to it and keep the graph as FLAT as possible. You lose a little power every time the A/F graph makes a jump (up or down).


Set the NE points in 400rpm increments, 6400 being the top. Put a little larger space on the lower NE points as you get below.

example:
1000, 2000, 2800, 3200, 3600, 4000, 4400, 4800, 5200, 5600, 6000, 6400

Sometimes it's better to make the top NE points even closer than that at 200rpm increments.

 

Hey matt, thanks for the tips....I didn't do the tuning....ynot411 did...but he taught me how to work the AFCII so next time I'll ask around dyno shops if i can rent the rollers...and just do the tuning myself....since the AFCII is real easy to work...

I'm sure my vaccum lines are working....I mean I been driving around AS IS since i went to north cal....and when I rev above 4k you can clearly hear a BIG switch over in the VI....tq does seem a little low...but prob becuz my engine is heat soaked

 

I'm assuming you're talking about my graph. I might go tune tomorrow to fix that. I will take your advice and set at those points...concentrating on the top end. It sux just having 12 points whereas steven88 has 24 points I was able to tune. I'm satisfied with how I tuned his and will continue working on mine.

My vac hoses have been switched back. The run graph that you see is the engine cold not reflecting the run right after where the Power Curve and TQ were much more consistent.

 

Steve

Love the dyno, Im going to have to pick your brain when i get my VAFCII in the near future. Im more concerned with my bushings at the moment

 

Actually, to me it looks like your VI is fine but Steven88's isn't.

 

My VI is working....I know so becuz I can hear it...and my vaccum lines are correct....it doesn't take rocket science to figure out if the vaccum lines are working either....

And my TQ is still higher than ynot411 in the mid-range....look at 3k RPMs....my tq is in the middle of 225wtq....if u look at ynot411's his 3k tq is at 200....if anything, his VI is jacked up...not mine

 

was this 4th or 5th gear?

 

Damit i want my car back right now. Looking at that dyno isn't making me any more patient in waiting for my 3.5 swap to be done

 

i'm guessing 4th... the A33B has a speed limiter that would not let 5th finish @ 160MPH +.

 

haha Chris, your car will be much more powerful with the 3.5L and s/c!

Zack - 4th gear fosho...both 5spd and 6spd maximas ALWAYS dyno in 4th gear to get the closest results....always been like that and always will be...

 

Cool just out of curiosity do you know what your 4th ,5th and 6th gear ratios are?

 

From the A33B FSM:

1st - 3.153
2nd - 1.944
3rd - 1.392
4th - 1.055
5th - 0.809
6th - 0.630
Final - 3.812

 

Wow your numbers are awesome. You guys have some healthy max's. Congrats on the #'s

 

awesome times andrew.congrats.. i remember you where expecting less!!! so lets goe break 13's or what???
