It blows my mind that a 55% increase in horsepower won't blow a stock motor. Nice numbers - be careful.

 

What about almost a 100% increase... Good job.

 

As Tuan has shown and we will be shortly, there is plenty of tuning to be had in the Unichip, especially with different exhausts and octane ratings.

 

Here you can see what I am talking about. After swapping out MAP sensors you can see Tuan's sexy A/F curve in red. Then after adding test pipes (blue), you can see that the Unichip needs a retune which should fix that ugly hump between 4 & 4.5k by pulling some fuel out of the map and pull the curve down between 5700 & 6500 by adding some fuel. The end result should have a flatter torque curve between 4000 and 5200.

 

Peter, how exactly is the Unichip the best interceptor style engine management system out there, when it doesnt drive the injectors directly, but instead...does simple MAF voltage tricks to get the ECU to enrich fuel? IMHO, its more like an SAFC with a boost pressure reference point...as a surrogate for load.

Very solid numbers...BTW..thanks for sharing. Good to see the G35's benifiting from the APS kits now.

 

Sharif I believe if you had time and knowledge to tune with the Unichip software on a true load based dyno you would soon see how quick and accurate the unichip computer is for thorough engine tuning - it's additional ability to control and map 6 aux injectors for very high powered engines, secondary timing ignition map for for high octane race fuel or NOS, and water injection control are just a few of the very distinct adavantages on the Unichip computer.

I'm sorry.

In retrospect, I sh/could have expressed my concern much better than I did. I am as concerned for your engine as a complete stranger on the Internet can be. I'm not a pessimist, but I didn't want to blow sunshine up your a$$.

That 10psi seems like a lot of boost to run on a stock engine, no matter how expertly tuned it may be. Personally, I would not settle for that on my car without a built bottom-end, encouraging words from the thundering herd notwithstanding. I would feel like I was riding a ticking time bomb, placing a sizable investment --and my own personal safety-- at risk. I must be more risk-averse than you are.

Good luck to you, friend.

 

no problem, I think there are certain ways to weather the risk as well. I badgered the hell out of Z1 with questions about how safe everything was going to be and what were the best steps to take, this is why I chose the APS kit because of their proven track record.

So far everything looks pretty good, I drove around a little bit and was able to get a feel for the car.. nothing is out of the ordinary with the gauges from what I can see.

Also the idea of water injection is the ability to turn the boost up a little bit amongst other things.

 

Your APS kit is a great start. Your state-of-tune, 1- or 2-step colder plugs, water/methanol injection, and other topical solutions will help eliminate heat, detonation, and/or pre-ignition under higher boost. Even so, stock pistons and rods were not designed to survive higher twist. I just read a post from the owner of a boosted stock VQ35DE who finally decided to build-up the bottom end of his engine. When he took the engine apart, he discovered 5 bent rods! At the time, his engine was not [yet] showing obvious signs of imminent rod failure. He was very lucky to catch it in time. Given the risks, it just seems as though an ounce of prevention is worth a pound of cure.

Like I said before, good luck with your new set-up. I am green with envy.

 

True, but I think the guy you're talking about was TRYING to blow his motor so he'd have an excuse to build it back up. He was boosting something like 12-15 psi with no tuning at all.

 

^^oops, that was the quote I was trying to post!

 

Thanks Peter....for your typical condescending reply and dodging of the question at hand.

The eManage with e-01, can store up to three maps as well (fuel and ignition), and the user can toggle easily between them. The eManage can also control AUX injectors. Maybe if YOU took the time to study the eManage, you would realize that is is not inferior to the Unichip.

BTW, I do all of my tuning on a load based dyno.

I'm out of this thread.


Back on top.......sorry for the hi-jack.

 

actually I'm kind of interested in what you guys are discussing, always nice to see different point of views

 

OK I am confused. I can swear I had read that the Unichip could only run one map, now it's 3???

 

i believe he's talking about the eManage.

 

Sharif my reply was never intended to be condescending though I do love to see how some of you guys with a marketing degree think you're experienced engine/dyno tuners.

In Oz a young tech/mechanic would spend a minimum of 4 years being taught by a highly experienced and qualified tuning tech before he was deemed to have sufficient experience to tune/map a customers car.

Why dont you come to the states, Peter, and talk to some of the best tuners and builders in this industry. Many of them dont even HAVE a college degree. I have worked on cars for many years, and I surround myself and seek out knowledge from other experts all the time. This is the reason that dozens of shops contact me weekly, for advise on their buildups. I dont advertise..how could this be?

Unlike you, I am looking out for the best interests of my customers....not just trying to push APS as the cure for cancer and AIDS!

YOU are actually quite excellent at marketing...even without a Degree. So there is no reason it can't work the other way.

 

While we are all comparing degrees and flexing our muscles, I have a doctorate degree and I vote Sharif for president of the 350z universe!!!
Sharif is one of the MOST knowledgable people that I have come across reguarding forced induction and any auto matter (for that matter). He obviously speaks from true knowledge and experience, not pushing a product to meet a quota...
Here in America, the straightforwardness and no nonsense attitude that Sharif displays is worth the most..no one likes a swanky used car dealer...

"come on down...APS TT, blown motor, no problem, want 500rwhp no problem...hell, want 600rwhp on stoick interanls, no problem, we got ya covered mate"

 

I do, face to face every year at least twice Sharif (SEMA every year and speak to many US and international tuners) and in addition they speak with myself and other APS staff frequently via email and phone weekly.

That's below the belt Sharif, APS customers always come first even at the risk of offending some US tuners who don't make the grade imho.

You can bet Sharif that if I come down with a serious illness I will seek the best specialists in that field of medicine with a good deal of practical expeience, rather than visiting a witch doctor with no degree or formal qualifications.

Have a good day my friend.

Peter

 

Subscribing....id like to see how this one plays out.
