I just came back from the dyno and it was an interesting day (to say the least) . My car has been modified with the following (you can ignore my sig ):

Invidia G200 TD exhaust
Helix Test Pipes
Strup Headers
UR crank pulley
Nismo Cams
MD 5/16" Spacer
UpRev Osiris reflash with the following maps tested:
1. Stock (-2 Degrees global timing. I'll explain later)
2. 91 Tune + ETC + 7200 RPM
3. Stock + ETC + 7000 RPM (-2 Degrees global timing. I'll explain later)


I have a 5AT BTW!

Just for reference I dynoed @213 whp/215 ft/lbs when my car was bone stock .




Here are my dyno runs





For reference (b/c the 1st pic is very blurry)




Also here are charts comparing my car to a modded 6MT revup



And to compare to a modded AT (only had Intake, exhaust, and underdrive pulleys but ran pretty well for a 5AT)




Here is my analysis (feel free to comment):

When I ran it was a little below 80 (not dyno friendly, but not 90+ which AZ is known for). My first run I dynoed @ 238whp/220ftlbs for a number of reasons. This was my first run (the light purple chart on the sheet) on my 91 tune and my car was pinging & pulling timing (actually the closed loop knock control was pulling timing in the midrange & after 6k and the topend fell on its face). The pinging was very audible so I decided to take 2deg timing from the global map (via cipher) so I could complete the rest of my runs without any concerns. I attribute this to AZ's finest 91 octane gas . Sometimes I sware these gas stations should be sued for false advertising. Putting that **** into your tank is no different from putting 87 into your tank . I'll end my rant. The rest of my runs were done using the bone stock map & the stock map with a 7000 rev limit.

 

pics don't work

I fixed them

 

My 2nd run, actually on the bone stock map, my output improved to 246whp, with no pinging thank god , but my car did not feel like its normal self and ran like crap IMO . The topend pull just wasnt there. My 2nd, 5th, and 6th runs were done using the stock map and the 3rd and 4th runs were done using the the stock map with the 7000 rpm rev limit & ETC. I think I am going to fill up with 100 octane and return to the dyno on friday and do this again. Honestly, I believe this may be costing me @15-20 whp (The osiris tune alone, on better gas [91 oct with 20% xylene), improved my ET by 0.6 & increased my trap speed by 3mph on the 1/4) . On a good note the osiris tune smoothened & improved (richened) my afr. I was running at least a point leaner on the stock maps .


Compared to the modded 6MT revup my car has noticably less lowend torque but noticably more topend power & torque. Its @ 10-12 whp in some areas and the torque doesnt taper as much (I'd like to thank all of my breathing mods for this even on crappy gas). Compared to the modded 5at the lowend torque is similar but my car has more topend punch.

My car did sound wicked on the dyno above 5k. It caught the attention of everyone . I was asked by everyone what was done to the car to make it sound like that.

I'm definately going to fill up with 100, add the 2 degrees timing back (and add another 2 degrees for ***** & giggles) and see if I can break 265 whp (I wish ). Just to think if I had a 6MT I would easily be dynoing @ 20whp higher.

 

Forsty,

Did you reset the "Learned Fuel settings" before doing your runs?

I ask because I recently went to the Dyno with my car and initial Osiris Tune. My car was also pinging and pulling timing above 6k, even though I was using 93 octane gas. The Dyno guys thought I had a bad tank of gas (BP brand). Also take note that the car progressively gets better as more runs are performed. I think that you will never get the higest numbers after resetting the "Learned fuel settings," but it is good to see how good their A/F target is for tuning purposes.

My mods list is:
Borla True Dual exhaust
RT high flow cats
JWT Popcharger
z-tube
Kinetix V5+ plenum

I had my car on the dyno in 2004 with all my current mods (minus the plenum) with these results:



I got the Kinetix plenum and Osiris reflash at the same time about 2 weeks ago. My butt dyno tells me that the car defintely pulls much harder and the midrange has increased a good amount...but that doesn't mean much.

I did 4 pulls on the dyno (different location than the first).

The first graph is with the "Learned Fuel Settings" reset. This is basically resets the ECU so my previous driving doesn't affect how the car performs and I'm guessing runs only based on what the guys at Osiris coded.



Here's the second run, done right after the last:


On the third run, I switched the maps so I was back to my stock ECU settings before Osiris and reset the "Learned Fuel Settings" again.


For the fourth run, I went back to the tuned map.


All numbers were SAE corrected performed on a Dynojet.

 

I think that plennum needs to come off and you need to run a slightly richer tune if your pinging alot

Considering how rich the stock ECU settings are if that A/F is accurate 14:1 13.5 is pretty lean....maybe richen it up another half point down to 13 flat and see if that cures the pinging a little

My A/F's were in the 12s/high 11's Still cant believe how rich the stock map on my 06 is if my charts are accurate

 

I didnt do this before my runs. I did this after I flashed the ECU. Do you think this may be worthwhile. I was pleasantly surprised that UpRev's AFR targets were excellent.

 

Richer than high 12's ? I think the plenum is fine for my tune. I just need a less aggressive timing map so the ECU is not pulling timing in open loop. Actually, my AFR on the tuned map started out in the high 12's and went down into the low 12's towards redline. My the AFR on my stock tune was at least a point higher everywhere but I was not pinging .

 

Why do you think the plenum needs to come off?


I agree that UpRev's AFR targets were spot on. IIRC most tuners try to get a 13.5 A/F across the board...my first run (after I reset the learned fuel settings) had an A/F spot on. I reset the fuel settings because I was told to do so for tuning purposes. It doesn't give the highest power output right off the bat by any means.

 

Another intelligent post by Serg-why would the plenum (spacer) come off? OP-FWIW my car NA made awesome power given the mods at 13:1 A/F across the board.

Same here. My AFRs hover between 12.8 ~ 13.2 under load... Seems to run the best in that range.

 

yea mine is low 13's across the board...im full bolt ons with utec tune, and depending on the map im 270hp-280hp...

 

Havok: Sweet Moses, dude. Those numbers are almost impossible to read with that baby blue text. What am I looking at?

 

This is interesting...I don't know anything about tuning but it seems that as I did more runs and my ECU "learned" during those runs, it leaned out the AFR a bit from 13.5 to 13.9 and I made more power across the board. You guys think the AFR target should be at ~13? How does this work with the trend my graphs show of AFR 13.5 to 13.9 --> more power?

I apologize about the light blue text...the printer at the dynojet facility was running out of ink. Maybe you can save and adjust the contrast?

 

Well, I'll try my best to decipher it:

Run 1: 238/212
Run 2: 242/222
Run 3: 244/229
Stock: 246/225

Do I win?

 

Btw: Havok, you have the portable Osiris reflash system, right? How easy is it to use? I don't want any downtime and shipping my ECU out, so this seems like a great solution. If you could give me some impressions on it (good and bad) that'd be great.

 

I don't really understand WTF is going on with all the dyno plots.

You need to explain each one better...

Where is the "before" and where is the "after" ?

Do you have a "before tuning" and "after tuning" or are these all just different osiris maps?

 

Which shop do you dyno your car at? Curious? I got mine dyno'd on Saturday for the first time at AZ Dyno Chip. Mine numbers were way low for my mods (239@ 222ft. lbs.) I think I need the reflash bad.

 

I just got my 06 G35 sedan dyno tuned at uprev in Austin, TX last saturday.

06 sedan 6mt revup, pop charger, z tube, mrev2 + 5/16 spacer, and a borla cat back. I will try and scan my dyno sheet later.

before tune
Max HP-246.65
Max TQ-233.92

93 oct. tuned
Max HP 255.37
Max TQ 239.55

The best part about the tune is the 16 Ft lbs I picked up from 2800 to 4000.
