Awesome, congrats on the success of getting that installed. Even happier to see vids and pics right after. That is one fast 350.

It's right on the under side of the charge piping.

If i told you, it wouldn't be accurate, because Justin from BTTW put MANY hours into this that he did not charge me for, simply because he loves his work. He came up with ideas, and would surprise me with them, and not charge me for the 4 hours it took. (ex/ the water meth tank was hand designed, welded, and carpeted as a one off project). The guy is awesome!

Go to this website and get a HKS F-conIS: http://1jzmerc.com/hks-faq/hardware/f-con-iS

I helped these guy's with mapping the F-Con and they will provide you with a jumper harness for the IS350.
I can send you a MAP.dat file once you get it that will get you to 350WHP on less boost safely

Once your there you'll have everything you need to push the limits.
Honestly just skip the Fcon IS and get the Fcon Vpro. Same jumper harness (I believe) and the software is out there to use it. PM if you have questoins about it. You would have FULL control over all fuel, timing, 2 step, rev limiters etc.

And yes I agree that your a/f are pretty lean. I just don't know the limits of the stock fuel system.

Can't be done on the HKS V-pro.

Reason: V-Pro can't control 12 injectors, you could drop the DI injectors and take full control of the PI ones but then the piston and combustion chamber design will suffer. Most likely you'll be lean without boost using stock PI.

You could piggyback it. But you'll have alot of CEL

Also you could use the DI only setup and drop the PI then run the HKS Vpro. But your just going full stand alone for no reason and losing alot of built in factory tuning that works well for daily driving.

With the HKS OSC you can fix AFR under light loads and map for the S/C setup with stock ECU. Doing everything and still pass emissions in almost every state.

I passed the NC OBD2 test 2 years back to back using the F-conIS and HKS- OSC setup and never threw a CEL.

If the OP does decide to go HKS F-conIS I have maps he can use that work.

I don't have any for the Vpro unless he drops in a 2JZ-GTE single turbo. LOL......... then I haz maps for that too.

Also your tuner will need the HKS tuner dongle and software. There aren't many HKS" pro tuners" left in the US. But you can buy outside the US and get the equipment yourself.

* The stock fuel limits haven't been hit yet. * I've hit the stock ECU map limit's with my last setup before tuning with the HKS unit. which is @ 6psi.
