Can anyone recommend a good piggy back to tune the USDM 2JZ-GE VVT-I ecu with?

 

The popular piggy backs are greddy emanage ultimate and the aem fic. If you have the money and the tuner, I would go with the hks f-con. I would go with the hks, too bad there are no local tuners here .

EDIT: I'm assuming you mean a boosted GE? Otherwise, if you just want to adjust the a/f ratio on an NA GE, an apexi safc or apexi neo will do the trick.

 

EDIT: you just swapped in the GTE. My post about the NA GE is irrelevant.
this is on the right track, but he needs a bit more than just a/f ratios.

i would go with the AEM FIC if you don't plan on putting a ton of work into your GTE. It will also allow you to tune the VVTi effectively.

honestly, without going big single, trying to put down stupid hp numbers, the f-con and emanage are a little overkill. you'd be wasting your money for features you won't use unless you plan on dumping tens of thousands of dollars into your motor.

 

Actually I think the AEM FIC is a better bang for the buck for piggyback compared to the emanage...Not sure about the F-Con haven't heard much about it.

I'm looking to put down 5-600WHP. Possibly GT35R. I'm already about mid-high 300sWHP on stock twins on 14psi.

 

get a standalone.

 

do i smell............a motec m600 or m800 full stand alone? hahaha just kidding thats way over kill but still are nice nice standalone

 

2JZ-GE's don't have stock twins, so you are actually talking about a GTE

You should give Camcon-T a try and see how many extra ponies you can get out of adjusting vvt. I know there are some VVT GTE's putting close to 500hp after going single and adding a fuel controller, or you can go BPU to keep the cost down.

 

clarification, i've no idea what BPU stands for but i've been seeing it a lot...i'm thinking the u stands for upgrade but i cant think of what it means haha

 

Basic Performance Upgrade

 

ah, excellent, cheers

 

You can make 500whp on an Safc piggyback if you have the supporting fuel etc...you wont be making that on a Gt35 on pump gas though.

 

GT35 is a bit small for your HP goals. As for piggy back the AEM FIC and Emanage Ultimate are pretty much on equal footing in terms of functionality. The only thing is that the AEM costs less. I would suggest a better engine management system once you surpass the 500hp mark though. Yes, there are people making more power than that on stock GTE ecu + piggyback but I would suggest a standalone. It's only a matter of time after 500hp when you get the itch for more power. I just cranked my setup to 30psi and I'm already craving more speed lol.

 

So you finally dyno that thing or what?

 

From what I've been told there are a few who have reached 600WHP on GT35R...Garret claims 450-550WHP I believe. If I do decide to go past 500WHP I might just sell the AEM FIC and go EMS hehehehheheheh. But I don't plan to turn my car into a trackstar but more so as a daily driver with some power. At 500WHP I should easily be able to do 11s.

 

That kind of power would be on race gas, assuming you were planing a street car you won't be running race gas driving around town. Secondly, the people that are making that kind of power out of a smaller turbo like the 35 will have full timing control etc...to maximize output on race gas, on pump gas you are going to be considerably lower.
