I think Peter is saying anyone who is qualified or experienced in tuning FI cars whether its Greddy, PE, Vortech, etc.etc., should have the know how to tune an APS TT with the unichip provided he can get or have access to the software. Question is, do you have to be an authorized unichip dealer to get that software? I was lucky enough to find an authorized unichip dealer/tuner in my area, if needed.

 

From my understanding you do have to be an authorized unichip dealer to get the software. How you become an authorized unichip dealer I don't know, but judging from the fact that there are very limited unichip tuners in the US it must be pretty hard or EXPENSIVE.

 

Perhaps this may be a contributing factor to FI 350Z engine failures. There are lots of guys around who reckon they can tune - there is a huge difference between those who can really tune FI engines and those who think they can tune FI engine, food for thought.

Do they have true load based dynos? If so please forward me their shop name. If not imho I'd say don't let them near your engine or it may well end up in tears.

Buying the tuning software is the easy part - having the knowledge, experience and right equipment to safely tune a high powered FI engine is entirely a different issue.

Assuming that the tuners are experienced with tuning FI engines, how hard can it be for a customer to ask them to order the software? The ordering and delivery is a straight forward procedure for any tuning shop - all one has to do is to ask.

You got it one, wasn't that hard was it?

I'm not sure though Unichip Nth America can clarify this for you.

Thanks

Peter

 

and all they have to do is say "Sorry, its too expensive/hard to get/etc." Sounds like it might be easier said that done.

your site shows a stock engine fitted with APS test pipes and exhaust producing 470.2 HP. Are you now saying this is not recommended unless we also upgrade the internals, therefore requiring a complicated tune to the locked unichip program?
Not trying to be argumentative, just want to figure out which TT to go with. If I want 450 WHP with the potential to increase, Im not sure if your system or Greddy's is better.

 

The reality is the APS TT system is no more difficult to tune than any other FI system with a built engine (forged internals), the base APS TT system on a stock engine does not require engine any tuning.

All built high powered engines require tuning by a competent dyno operator with plenty of computer mapping experience, this is not easy to find in some parts of the US.

Simply put what applies to the APS twin turbo system in terms of high power tuning also applies equally to any other brand of twin turbo system, what is it that you don't understand about this issue?


I've always stated that engine power above 400 WHP should have at least stronger forged con rods - there's nothing new about that fact.

I believe that the APS TT system has superior technology and is far more complete that the greddy system (no disrepect to Greddy) though the reality is both twin turbo systems will require dyno work and custom tuning to produce 450 + WHP, (forged internals would also be a wise investment) that's the exact reason why the APS twin turbo system has tuning data to support a maximum of 400 WHP - we don't want to lunch your engine.

Thanks

Thanks Peter, PM sent.

 

Pm sent to you.

Peter

 

Yeah expecially if the engine management comes with a unichip piggy back like the APS TT.

 

Peter,

You sound like a politician. You answer the question without answering the question and then you turn the focus on something else. With all due respect you are full of chit.

Why don't you tell brittian what his options are at the moment if he wants to build his motor and push 450rwhp safely? If he does not have an authorized unichip dealer in his area he will have to drive the car to Tuan at GRD, which in his case might not be as bad as me driving from Miami. Either way stop hiding the fact that there are very few authorized tuners of the unichip in the US. This is not the case with the other TT's systems. Stop trying to make it sound like it is just as difficult to find a tuner for Greddy TT's and other TT's system as it is the APS TT.

 

Brittain,

The APS TT is the best and most complete TT on the market right now, but if you don't have an authorized tuner in your area you won't be able to hit your power goals. If you are going to build your motor and want high hp if no authorized unichip dealer is available you will have two options.

1. ship your car to the nearest unichip dealer.
2. Drive you car to the nearest unichip delar.

I was going to buy the APS TT and build my motor but when I found out that there are zero unichip tuners in FL, I went with the greddy tt. What good would it have been to have the APS TT and superior technology like Peter states, if I could not acheive the power level I am shooting for?

If you have an authorized unichip dealer with the software in your area and you are shooting for 450rwhp or more then get the APS TT IMO. Also if you are willing to ship or drive you car to the nearest tuner then get the APS TT.

The reason I went with greddy is because with such a high hp car things are going to go wrong. It is the nature of the game and when things go wrong I can't have my tuner 2500 miles away from me.

 

I hear you. I'm looking into a TT system now. Driving is not an option for me and shipping would be $2,000+ on the low side.

As Peter had stated before, there is a dealer to be opening up in my area, but I do not have any idea of their mechanical and tuning skills. Plus I don't want to turn my motor into a time bomb, so I'm still looking (as opposed to buying).

 

Well if you don't plan on building your motor you don't have anything to worry about as the APS TT comes already tuned out of the box. The people that should concerned about the availablity of unichip tuners are the people that are planning on building the motor with forged internals.

If you buy the kit from Tuan at GRD he will map it for 91 or 93 octane and you are set.....you just have to find a qualified shop for the install.

 

Actually, if you later decide to replace or add performance parts like Cams, cats, plenum, you will still need to have it " tuned ". Basically anything that will improve breathing for your Turbo, tuning is needed.

 

And there is nothing wrong with that. I am just trying to inform everyone that is looking into this kit to keep that in mind......if no unichip authorized dealers around....no tunny.
