Induction parts + ECU reflash dyno results

DannyGT · 05-17-2009, 12:27 AM

5k for 40 to the wheels not BHP is actually not that bad at all!!!

Also, i would like to add I ran on a DynoJet 7 times stock and my last 3 runs were IDENTICAL 282whp and 241wtq...Do I have a special Z? Not at all!

Really, I dont care if this dyno said you had 350whp, I'm just interested in the before and after gains that seem to be fairly consistant for the mods you have and other members across different dynos!

I'll be going back to the dyno this week to see what my difference's are! I'll be happy with 20-30more whp...

We noticed the same thing. The 370Z is so tightly regulated that it nails the peak HP within something crazy like .4hp every time. Insane control. These ECUs are amazing, and we're working to figure it all out.

Glad your see'n similar results...Now, give me your ECU!

No, but seriously, if you need me to do some testing here in the NYC tri-state area let me know...

I would hate living in California!!!

I think the gains are great. Congrats and thanks for the testing. It really helps the rest of us out.

whats the diff between a reflash and a tune? The only reassuring thing to me on looking at these graphs is that the reflash helps with low end torque loss with these parts.

Reflash is the term for what is being done. You have to flash the memory on the ECU.

You're talking about the difference between a Base Tune, and a Dyno Tune. A Base Tune is an off the shelf tune that was done on some other car on a dyno. If your car isn't exactly that car, then your gains will not be the same. A Dyno Tune is your car specifically being tuned.

I agree with original poster that a supercharger is the only way for us CA people to go. I have a bad temper and if some cop wants to take my TT370 I would go ape chit on him. CA does suck with all its laws but hour and a half to the beach or the slopes isnt bad.

ok I just read all of that and all i can say is we really need to have a process for just going in and indiscriminately just deleting the last four pages.

Other than that I picked up the same stillen headers for $470 shipped, I have some $300 test pipes lined up, and i have some extra throttle bodies I'll be using as cut-outs from there and doing some muffler mods(free). So you can either call that ~50hp for < a stack, or just that I'll have 4G's left to throw into suspension which won't add crap for hp. Oh and I can install all my own parts.

Edit: found the same ss304 test pipes for under $200

I didn't want to start a new thread on this so I figured I piggy back on this thread..
I have a 2009 370z Touring with Sport. I installed the Stillen G3 intake, Stillen HFC and Stillen CBE..Now is an ECU tune absolutely necessary to get the full benefit of these bolt ons?
Man, I'm so freakin confused with this stuff! Yeah, I'm a total rookie! I just got into this modding and man, it's so addicting! I don't know what to do next. Anyway, I hope I didn't piss anyone of you off with my rookieness!

I dont know IMO it seems like a lot as well.
Forced induction guys I think are a little spoiled to begin with especially the EVO's guys who can make lots of power for cheap.....us Subbie guys have to spend a little more (FTL).
Either way dyno's are cool and all but lots of factors play into it(high reading- low reading- correction factor etc.) Good to see base-line and additonal power but when it comes to the way the power is delivered it is literally about driving the car and how and where the new found power is.
Nevertheless if the driving characteristics have changed and it [put a **** eatin grin on your face.......then it is money well spent.
I have to agree with Brazilbro if you are going to mod the car and want gob's more power just cut to the quick and throw a snail on that whale.

Good luck with it

What reflash is this?

Blue line: Stillen parts + Technosquare ECU reflash + dyno time.

In summary: $3,200 in Stillen parts gave a 26 hp increase over stock to bring it up to 328 compared to the original 302.

$700 for ECU reflash and dyno time ($500 for reflash only) gave an extra 15 whp for a total of 343 whp.

In total, it was nearly $5,000 including installation of the parts to gain 40 whp over stock. The throttle response in now extremely precise. The sound is wonderful, the over-rev to 8100 rpm is phenominal. The "Buzzy" engine vibrations that car magazines have been talking about are no worse above 7500 rpm. If anything, it smooths out a little.

One last thought: Lets pretend I gained 2 hp from removing the stock rear exhaust section. This car would have made 300 hp in this dyno. If the stock engine was 332 crank hp and it made 300 hp on this dyno, that's a conversion factor of 1.1066 for frictional loss (332/300). After mods, this car is making 343 hp on this dyno, which would be roughly 380 hp at the crank (343 x 1.1066). Not bad.

Dude!!!! Your return on investment (ROI) totally sucks!! In terms of a "biggest bang for the buck" you just got got laid over the railing. I hope they at least gave you a jar of free vaseline for the rape you just got.

You just paid between 3 to 4 times over the average cost for HP per mod-dollars spent. The acceptable average cost of a mod per HP gain is $25 to $30 per HP.

To be considered a "good" ROI for car modding the general ratio for
mod-money spent per HP gained is $25 to $30 for every 1-HP gained. You paid $125 per 1-HP gained given your configuration!!

did you figure in that he cant go turbo......?...... some of us in more modern states have a hard time passing emisions.

Not to mention this is pretty much near stock reliability, something boost just cant claim. Coming from a 350 myself gains like this are pretty awesome! Even a Vortech kit for the 350 turns into near $10K when you factor in install, tune, extras and supporting mods like I/H/E and thats a headache Id rather not go through again.
