All toyota did was switch the pins around but everything on the engine are the same including the ecu connectors.

I am currently using the RCF OEM headers, i don't mind for now as articles says its more durable than the ISF stock headers. I will eventually get aftermaket headers, but for now i simply deleted the cats. I am using a BitEdit / BitBox software to flash tune the stock ISF ecu. I am an original haltech guy but i am now experimenting with ECU flash tunes. So i have the basic knowledge and experience to tune the car myself.
Now that's very curious, perhaps another option in tuning. Looks like a USB interface to the ECU. Working through the site, but I can't find how it specifically interfaces with the ECU?

It is straight forward, just tedious. Regarding the low side fuel pressure, i made a custom hanger by combining the ISF Hanger and the RCF hanger so i can use the stock RCF pump or a Hellcat pump if i wanted. Then i deleted the intank FPR and added an external FPR so i can control fuel pressure with a gauge from inside the engine bay. The RCF Fuel system doesn't have a return so i used the existing ISF return line for my external FPR. so now i have plently low side fuel pressure at my finger tips, it's also vacuum adjusted. The bigger HPFPs are cam driven so that doesn't affect anything, the cam speeds determine the pressure all the ecu does is provide power and ground to those pumps, the higher pressure from those HPFP is actually a good thing. The bigger Port injectors is also a good thing, that's like a simple injector upgrade so there's more fuel to play with. But most importantly since you'll now have alot more fuel than the ISF has you will need a tune to make this swap possible, similarly to when you install bigger injectors on any car. So if you're doing the swap you will need someone who can adjust the fuel or your car will run pig rich. I tune my car myself so this is why it was easy for me.
Any pics of your work? Couple ways to go about the fuel setup and I am very curious how you ended up where you did.

Did you stay with the oem motor mounts? Also, how difficult was the tuning process?

And I love this! I was a Haltech guy back in the day as well!

Nice work man. We look forward to seeing the progress!

BitEdit / BitBox is a very complicated tuning software, if you don't know what you're doing you could brick your ECU in an instant which is a very expensive mistake. It's not a new software, this is what all the other tuners for this platform uses with slaves devices like dimsport or other handheld flashers, I just figured it out on my own since I have some tuning experience. Some uses VF Tuner also which I am not very fond of.

It's a security dongle that's registered to the owner and said owner's purchased modules (ECUs) you have access to. It's online server based as well.
You'll need a tactrix/mongoose cable to reflash the ECU via OBD2

First off, nice homework and transplant!
Question, does this software allow you to see how the maps interact with each other? And can you isolate the cam VVT-i maps?

TIA!

he just rounded up nothing wrong with that 😆 🤣

I missed that other guy's question. If you watch the video all the way to the end you'll see another Dyno sheet. There are 2, the second one reads 439.44whp, it's easier to say 440.

I finally got good ethanol now so I'm at E77, I adjusted the tune and added a few more degrees upping it from the stock timing. So it should be making more power now, I'll Dyno soon to see exactly how much. Only thing left now is to add aftermarket headers to see if I can break 500whp all motor. Got my eyes on some UEL PPE headers.

Hi, here's a link to the list of the maps available in the software and what they do. See below

this is super cool, so can you adjust the VVTi and direct injector timing and stuff too?

Have you dyno'd since you got the 77% ethanol and messed with headers or any other mods yet?

Where did you get this done and how much did it cost? I have been looking to 2UR swap mine with the RC-F trans along with other components. Thought about buying a wrecked RC-F at auction and part it out.

Hi, yes you can adjust the VVTi maps and port / direct injectors. I no longer use bitedit to tune as it is a bit limited, i now use Winols, specifically since i'm tuning for boost now. I sold the RSF last year to my buddy. I have a turbo ISF now. The RSF is making close to 470whp currently on full E, still with stock headers. He'll break 500whp for sure if he installs some PPE headers. He said he's in no rush however since he's happy with how the car is currently. It's pretty strong and quick.

I did everything myself, in my garage. Took me about a week. The whole swap cost me what i purchased the engine and transmission for. That's it.

Aw man, thanks for the update, hate that you sold it. It seems like an awesome project. I've gotta look into that tuning gear for sure. Any chance your buddy gets on here?
I'd love to see this thing at the dragstrip

Any chance we could see your ISF turbo setup in a build thread? Saw your vid on YouTube and would love to get more info on the layout and how it's working for you. From your comments there you're going to be doing some additional support over the summer as well. Would be awesome to see the process and results.
