I also wonder if a full blown stand alone ECU would help to gain even more HP and a more reliable tune....If I was going to go with SC I would look into this, just because I would want to buy more mods and make sure I am milking all the HP out of them in a safe manor.

Hmm... i'm thinkin Greddy E-manage ultimate...not a pure standalone but functions as one

HKS FCON PRO - AEM - win if you want a stand alone

I would be happy with free ware flashing software and rom editing and an appropriate cable.

Haltech FTW :tup:.

But i think Osiris tuner should be enought, it's not a TT with 600rwhp +.

Stand alone cost - $3000 installed
Extra tuning - $800
The laughs from friends when you only gain 5hp - priceless

A direct comparison to GT-R's is not apples to apples because the G/Z platform is not factory turbo, but look how far the GT-R can be taken on just the Cobb. I doubt on one of these Stage 1-3 kits that a standalone will be any safer or gain any significant power. As is often said with mods, the increased performance is from lightening your wallet.

I'm not sure how that answered the question, but it is interesting that you are going for TUV approval. I don't know much about the specifics, but I assume it is a very difficult thing to do. Probably harder than CARB approval since they look at so much more than just emissions. Hows that CARB approval going anyway?

Numbers are looking good GTM.

Mine is on the way, woo!

Agreed. When good quality reflash software is available, standalones are probably only necessary for high-boost/built engine applications.

A good reflash will be light years ahead of a lot of the stand alone options out there with in limits. We aren't talking about some of the lame "power programmers" that were available back in the day that offer simple tuning options. We are talking about being able to reprogram all or 90%+ of the factory parameters. In this situation until you are well beyond what the factory sensors (mainly maf/map) can handle in terms of airflow, you will probably be better off with a stock ECU on a reflash.

When the time may come that the mafs just aren't able to meter the much larger volume of air coming into the motor, or you need so much fuel that your injectors are too large to be able to idle well w/ in the stock ecus capability, or similar, then a stand alone is going to be the better option. However to achieve the same level of driveability, plan to spend some time, and some money. The factory ECU can compensate for almost any change in atmospheric conditions, duplicating this ability w/ the tables offered in most stand alone options is where a good tuner with experience will shine.

Agreed on stand alone in terms of cost, personally I would not go that route if I did there are only a couple of units I would personally consider.
I would reflash a stock ECU everytime generally (with a reflash that is easily removed , i.e. uninstalled if needed) but stand alones do have benefits in terms of add on module support, EBCS direct control , WBo2, EGT etc etc

GTM

Are you going to monitor EGT's when trialing different exhuaust set ups? maybe give some data with a stock, HFC, TP, CB - 2.5 / 3in , what ever you test?
I assume most customers who upgrade will already have or will install at least a dual CB, but data to show the benefits other then HP and TRQ would be interesting, especially when timing , fuel and EGT are involved at key rpm areas.

With our turbo system we have made over 600RWHP without any problems, and we have many cars ruining 500 WHP+ on the HR and VHR for last couple years worldwide with stock engine with our GTM flash and still running strong to this day . I think tuning, having efficient system has a lot to do with it. I personally feel 450 to 500 hp is the sweet spot for any street car . and with good driving habits you can get a lot of usage and mileage out of the setup .

Running straight water or water/meth injection system has a lot advantages especially to high compression engine like the Our VQ37VHR. i personally like to use those system as an added safety net more then just a power adder, unless you are doing direct port system witch is the only way taht you really can control and make sure your injected an equal amount of water or water/meth in the engine .

it a lot of fun

Hi, Sam. What amount of boost is good on the VQ37 before 91 octane pump gas starts to cause detonation issues?

It is a very effective solution, reasonably priced and widley used in the oem turbo german cars. It had worked very well in all the testing that we have done.

Sam

We have not played with E85 yet for a couple reasons, lack of gas station that supply that fuel and also the E85 requires some huge injectors 1000cc+ to keep up with the fuel demand that E85 requires. sense we are utilizing the factory ecu that option becomes more challenging .

As for C16 it is a great option for race cars, very specific fuel that likes running lean and loves timing, not for street cars application.
