BRZedit tuned + Bolt-on parts
 

So I was finally able to get a tune done on my car after getting most of my bolt-on parts other than the header (undecided due to FI option).

I went with BRZedit with PRE, which is a custom tune and took a long time to do but worth the wait.

Here are the Dyno charts pre tune, post tune and a comparison chart.

Bolt-on parts include:
Perrin CAI + Silicone inlet hose
Perrin LWCP
Invidia catless front pipe
Invidia N1 catback exhaust

pre-tune.

BRZedit tuned (the 3,5k dip was due to the AT converter locking up, and tuner didn't quite get the pedal timing right)

Comparison chart: Blue line is before tune, red line is after tune.

Biggest gain was the 15 torque I gained in the 4k RPM region, and 12HP top end.

My buttdyno feels that about 4.5k rpm, the car pulls harder and the power seem to be more smoothed out. By smooth, its hard to explain, but it feels as if "patches" of power loss and torque dips are much more smoothed out.

After WOT 1st gear to 2nd gear, the drop to about 5k RPM in 2nd gear pulls pretty damn good now.

I need to mess around with it more since I only drove it home from PRE, and I should be able to give a better feed back after the next AutoX event.

Over all I am pleased with the tune, and yes I know the power loss compared to MT does indeed suck. The torque converter will rob about 5 ~ 8% HP compared to MT.

This is still a conservative tune, so it is set to have my AFR to taper a bit so its not running too lean over 6k.

Get some headers on that bad boy and that dip should go away!

Interesting numbers. I dynoed at 171 there last week. Probably the biggest difference between our cars as far as the dyno numbers are concerned is I have the Nameless overpipe with high flow cat. I wonder why I dynoed so high without a tune compared to you.

Edit: Nevermind I remembered you have an automatic. That's probably why.

Auto make less power. With a tune you would prob be where i'm sitting at. 185WHP

Dang auto robs power

Yes the auto robs power but it can handle more HP and torque then the manual

I'm curious what I would dyno at... But I want headers first.

I really wish someone from PRE remembered what a stock manual got on the dyno they have. One of you guys needs to do it. Nick and I will pay for it. It's only $25, so I'll pay part and Nick will too! Come on guys! Man up! I'm sure @BRZPDX would like to see a stock automatic on the dyno as well to see what his parts did.

I'll be down in a couple weeks and mine is still stock

I could drop by most any day for a stock baseline. No performance mods currently, and I'm 15 min from PRE.

Call them and make an appointment 503-619-0055. If you need Nick or I to help pay the $25 then let us know. Also make sure you post it up here when you're finished and if your stock car was manual or auto transmission.

It should take 30mins or so.

I'll give em a ring on lunch.

I dyno'd at 189whp on a Visconti pump tune (EcuTek) with pump gas on the dyno at PRE. I only had pulleys and a muffler delete axleback at that time (I have other mods, but NOT power adders). I've since added a nameless catted over/front-pipe. No dyno update on that since I have dropped EcuTek and going to BRZedit with tuning at PRE soon! Will post updates after that happens..

I may take you up on that offer, lol. We bought a house this week and I may get in trouble with the wife if she thinks I'm spending money on the car before we get our house stuff.

Called PRE, scheduled for sunday before the BBQ.

BBQ is sat!

I meant saturday!

Cool. You should have good news for us when you get to the BBQ then! :)
:thanks:

Nice! Did they do this with a pro package or your personal?

Here you go @NickFRS and @stockysnail. I'm headed down to the BBQ but you might see this first.

W.T.F... My car is boarder line lemon. Just means I need that FI sooner than I thought

Interesting. That's 1 more hp than when I had mine. Doesn't make sense since your's is stock. Either they calibrated their dyno differently or the parts I added took away power.... :sigh:

I actually talked to them about that because he mentioned that stock they've been dynoing higher than when modding. They said that in their experience, bolt-ons like intake and exhaust will steal a few hp. Their opinion was that the limiting factor with this motor is head flow. Told me the best thing to do first is get a tune, as you'll definitely get a power boost.

We need a dyno run from Perrin of stock vs with intake and exhaust to see what they get. Not saying it is happening but some shops calibrate things to make things look bad so you buy more services like tune's and parts to get more money.

Not unless you go with a stronger tranny :P

If you compare johnnyrocket's stock car with mine that has all the goodies, my car makes about the same power within a few horsepower, so it would seem that the bolt on stuff does nothing for performance. I'm guessing when a tune hits the car the bolt on stuff will help a tiny bit in getting a few more hp.

It's the clutch that's the issue

This. Also the header on our car is a bottle neck.

Yea, it's likely that you're just missing the piece to bring it all together (namely a tune). Like I said, they told me a tune and head work are where you'll see the power gains. What you'll see more of with bolt-ons is change in powerband shape.

In the stock form the Automatic tranny can handle 450 HP and 425 lb/ft of torque... The manual can only handle 220 hp and 200 lb/ft torque before the clutch starts slipping... That's what I was referring to. So at 220 hp you have to upgrade the clutch.

The Perrin car is at 300whp on stock clutch, there are AVO cars running 250+whp and 220+wtq on stock clutch.

I said it starts slipping at 220... Not that you have to upgrade it... But its highly recommended...

@BRZPDX 10 bucks for dyno results! :D

Ok, so I got my baseline numbers and my numbers after the exhaust was installed... Baseline was 146.3 HP and 120.2 lb/ft torque... After doing my exhaust I'm sitting at 167.3 HP and 145.8 lb/ft of torque now I need to get a full tune for it and ill be good to go or my F/I kit... I like the numbers so far but still have some of the torque dip problems... They should go away when I get the full tune done.

Was the dyno done on the same day? Its hard to believe a 21hp and 25 lb torque gain from a cat back exhaust on a n/a 2L engine. Is this with a base map tune or just bolt on exhaust without the tune?

Just for reference, I have a catless front pipe, 2.5in Invidia N1, Perrin CAI, LWCP, and a open source custom tune with BRZedit, and gained about 13hp / 15 lb torque.

If your numbers are 100% correct, then your bolt on parts will be the highest power upgrade I have ever witnessed on this forum, including headers w/o a tune. A bolt-on header gains about 5hp w/o a tune.

It wasn't on the same day but the ambient temp was only 2 degrees different... I dont have a tune from brzedit or fa20club or anything like that but I did do a little tuning of the air/fuel mix and some rpm changes... Nothing major... I was surprised by the numbers on the Dyno as well... I'm gunna tun it again when I get my header and overpipe as well... Gunna do another baseline and then with the header and overpipe...

For sure, I need to see that result!
