We'll I'm waiting to get the graph e-mailed to me. However the net result after about 2 hours of "leaning out" some of the fatness is 358WHP.

On tip in I have slight pinging with the base config, however my power is really low then, and it only pinged on the dyno... I never go 5-100% throttle in 4th @ those speeds. (I started my pulls @ 1750 RPM)

So on the road I have never created the situation of ping.

Now that I've seen the Unichip software... I'm not that impressed. It has 12 load points, you can use fractions on the fine tune, etc. It does smothing, and some other nice stuff. It gets the job done... Its not aweful, its not spectacular. (The boost control table was especialy "lacking")

We didn't do too much other then lean it out some. Pulled slightly more timing where we leaned just to be safe. I wasn't too concerned with getting an AWESOME tune. I just wanted to roll it on the dyno, get a base number, check my A/F, run @ differnt loads watching temps/knock etc.

APS added some timing @ cruse speed and low load. We removed all that... We were sub 10 on A/F past 5k, I had them bring it up to 11s and still drop off by redline. Fighting the stock ECU past 5k is what we were dealing with.

The result was a bit wider peak TQ/HP and on the ol' massage numbers I gained 30hp peak, and 40+hp is some of the vallyes where the A/F was really bad.

Not bad for 2 hours of dyno time, made sure everything is running without knock/ping.

When I take it back in... I'll have the EU in there, as well as new exhaust system, pistons, etc. Then I'll worry about getting the perfect tune. For now, its just pice of mind.

358 is nothing to scoff @.

Is this the APS ST or TT? Im guessing ST?

 

It is TT. Self install right?!?

 

Yes... This is a TT, that I installed myself.

 

You definitly have to get a duel exhaust on that thing.I was 360 out of the box with 10.0/1 a/f.This was with stillen exhaust and h/f cats.I put in test pipes and got 397hp and still rich. 400+ is around the corner with a little leaning out and still safe.I've been running this for 6k now.

 

i have stock exhaust....377 rwhp and 320tq with a ati procharger(7 psi pulley)..hope you didnt spend too much...3 grand for me..hehe

 

I may end up with Exhuast before long.

I was lucky enough to only get charged for Dyno time on the tune. The software is really simple, and I had 2 sets of eyes watching everything.

Unichip is big with the Subi guys, so he was a bit shocked at the timing they were running on the VQ. Because neither of us are familar with tuning the VQ we did some conservative measured increases (Decreases actualy... Fuel and timing) and left it.

This is my 1st project car, so I'm taking some measured steps. I'd LOVE to get out of this without blowing an engine and producing somewhere in the area of 600whp by the end of next year. (Right when the trail blazers eclipses 800whp)

I'm waiting for the new Greddy exhaust for the 350z. If I remember correctly it will be dual 3". That will hopefully be the only buy there... And then a re-tune.

Then the rest of what Shairf and others have figured out by the time I get there.

It really depends on a lot of things... I was 358 on the DynoJet here in town...

To put this into perspective...

Another guy pulled 430 on this dyno, and pulled 490 on the dyno @ unichip. No changes at all.

So there is a 60hp swing based on dyno, and how much correction etc... (These dyno numbers were taking 1 day apart.)

377 is great!!! I'm sure it feels a lot better then stock... But I wouldn't make an apples to apples of our numbers.

 

wow, you're so cool!

 

Hey spd....good work.

Couple of points for you.

As mentioned, get yourself a very free flowing exhuast. 2.5 inch true dual for about 8-10psi, and 2.75-3inch for anything above that.

Curious why you retarded the timing at cruise and low load. Timing advance under those conditions is desirable, as it results in a more complete burn, better mileage, and less emmissions. Since there is little to no load on the motor, you can run very high ignition timing advance without any chance of harm.

Looking good so far...and congrats a successful self install. As you know, the APS TT is a very challenging kit to install, and you should be very proud of your accomplishment.

 

This thread is a good advertisement for the turbonetics kit, due to its similar numbers without tuning. out of the box power can't be beat.

 

One more thing...you numbers are about inline with what we got on a G35 APS TT customer car. Made 360whp without any tuning, on a stock exhaust with only test pipes. Exhaust back pressure is killing these numbers.

 

I didn't realize I was going to get heckled by some...

As always you've been very helpful Sharif.

With how the Unichip tunes... We were not sure where the tip-in ping was coming from. As I'm sure you're aware one way to find out where you are on the map is to do a pull... Tapping that button every 500 RPM to color the map. Without a DynoPak/Mustang? (Load dyno) I have to do a pull... tune... do a pull.... tune... repeat... I can't dail it in and tune.

Well right when I went F/T it would ping ping, and then clear up. However we wern't sure where on the map it was doing that... We knew the RPM but didn't know the load site... Because the load site can chang so fast from 0--> 100%. So we just cleared all the advance they added. (It was 1-3 deg only @ very low load numbers 50 etc.)

I figured since I didn't have a tuner who knew the VQ well, and I didn't have an infinite amount of dyno time. (AKA $$$) I'd error on the side of caution this go at it.

Once you get those new exhaust kits in... I'll have to go back to the dyno for a longer period of time. However I'm tempted to wire the EU before I do that. Just cut out the Unichip right here and now... That way I can blow up my own moto, instead of paying other people to blow it up.

Well it does cost less to tune and blow your own engine, though signficantly more to rebuild the engine.

Maybe it's smarter and more cost effective to find and pay a professional tuner.

Because I'm doing my mods in stages... I'll have to get retuned at least 1 more time. (After the engine build.)

Because some of the mods I want to do before the build are sub 1k things... I want to do those over the winter. Most of them will require at least a sanity check on the dyno. (Exhaust, Injectors, Boost Pressure)

Getting a tune in Cali or some other state really isn't a viable option. And since no one anywhere near me knows VQ. I see two reasonable options.

A) Get it good enough, and safe... Then do one holy glory tune after I have saved enough money to do it all. (Build, etc)

B) Do it in stages, re-tuning every 1 or 2 months as the parts go on.

Being an instant gradification man... I'm left with no choice but B.

I love your kit, I love the intercooler, the turbos, the piping, the POWER, everything... But when going for more then what you kit offers out of the box I need more tuning options local to me. I don't get enough "holiday" to make a trip to cali everytime I add a part.

 

Well what's the problem then?

It should not take more than 45 minutes on the dyno to tweak the computers tuning maps after the mods.

spdkils would still own you in a race, because its the AREA UNDER THE PEAK numbers that matters, and his TQ comes on much sooner than you, his hp does to till the very top of the powerband. If you knew anything about dyno's, you'd know peak numbers dont = faster car Decent numbers spdkils, your obviously very rich, I look forward to seeing what you pull with the Greddy Evo turbo exhaust-I thought it was already out?

 

For some reason I thought it wasn't out yet... Is this it?

Can you beat that price Sharif?

I'm not there yet... The only debt I ever keep is a car payment, and my house payment. Not living on credit cards has its benefits.

If people are seriously stupid enough to compare dynos from two completely machines, in different cars, on different days, etc go ahead and buy the kit with the best marketing department. Untill then let me know when any ST or SC kit traps over 119 on stock internals.

 

This isnt the new 2.75 inch EvoTT. This is a modified version of the Evo2 exhuast. Mark at SGP racing removes the Y-Pipe, and makes this new section in house...nice work. The piping is between 2.25 inch and 2.5inch.

For the big boost cars, Mark and I both agree that 3 inch dual is ideal.
