best 1jz engine management options...
im working on a 1jz swap currently. Its going into a sc300 auto. im staying auto.
my goals are 400whp on pump. daily driven.
what are my ems, piggy back options?
i know safc is used by many.... but is it plenty for 400whp?
some have said emanage blue... how well does this work with a 1jz?
is there a map ecu option for 1jz?
i know full standalone would have the most tuneability, but i dont feel i need to go that far for 400whp.
any input would be helpful. thanks

Raw HP is one thing, reliability is another. You can aquire 400 with simple tuning items I am sure, but it probably won't be as reliable as a fully tuned vehicle. No point in wasting that kind of money if it might fall apart on you.
On another note, what transmission are you sticking with? 400~ HP is pushing it with the stock Sc300 A/T.

If 400whp is your goal, you should be fine with the stock ECU and a simple piggyback A/F controller, e.g. AFC, FIC, etc. You don't need a standalone or high end piggyback for 400whp. Reliability shouldn't be an issue at that horsepower rating.

btw- you dont need a map ecu. the 1jz already uses a map sensor

HKS F-Con is always gonna be a good choice, but as stated above. The only true downside is going to be finding an HKS Authorized Dealer for tuning depending on where you're located. My tuner loves tuning with AEM EMS. Many of the Supra guys love MAP ECU. I've never used it, so I won't even try and dissuade you. If I could make one solid suggestion, that's avoid GReddy's E-Manage. Many tuners I've talked to have had negative experiences with it.

bro keep it simple for your pocket and sanity
my friend i have 2 buddies here with 1jz , one putting down 467 with a mines ecu ( a reworked/reflashed stock ecu ) and a super afc and been running it at 21psi for over 3yrs and the other put down close to 500 with a blitz access ecu (again a reflashed stock ecu that raises rev lim eliminates fuel and boost cut) and super afc
thats all you need for your power goals , nuff said

A mines or sard ecu plus safc would be your best option but those ecu's are hard to find and sometimes it's not known what they are tuned for. Outside of boost/speed cut removal some of the other stuff is unknown. For now I say boost/speed cut controllers and safc II. Also check the tuners in your area to see what EMS they work on.
