-I don't know what tunes Shiv has given you, but I would hazard a guess he will have to adjust it if you are planning on using injectors and header. I would also guess that he can also tune it using either the TMAP that comes with the kit or any aftermarket MAP sensors. Again, you will have to get a custom tune from Shiv.

-The CARB tune is based on ECUtek and not OFT, so if you are trying to be CARB legal, you'll have to switch. As far as specific parameters? I have no idea.

Thanks, that all makes sense. Yeah, I want to stick with an OFT based tune and I'm trying to figure out what I need to do. I'm a little interested in tuning it myself, but it seems like having someone else do it initially is a better idea for now. I did read the CARB tune was available online somewhere, but I guess there's no guarantee I could see the maps in it. From what I've been able to find about the other tuning stuff so far, the OFT stage 1 base timing maps, and maybe other things, are too aggressive for FI. Oh well, no use overthinking it since I don't have the kit yet. I might practice tuning the car on my own in the mean time.

Anyone have part number for the 2.5" pulley?

This isn't a case of tweaking the maps from NA, there is a fair bit of work involved. There's no way that I would consider using a NA stage 1/2 as a base, unless you literally wanted to spend days getting it to run well and then a few paid hours on a dyno getting the final setup sorted. TBH you'd be better off starting with a stock tune.

The CARB tune is ECUtek, you won't be able to flash or use it using anything else. Nor can you view the maps.

At this stage, why the appeal of OFT? Most of the tuners that have done loads of stuff on the E-Force use ECUtek, who already have time invested in making them run well.

^this. I understand why folks would want to use something they already had but there is just so much more support and knowledge base on ecutek it would be very silly not to.

It's like insisting on using MS paint since you already have it instead of just buying Photoshop.

The main appeal of OFT to me is that it's an all in one solution that has most gauge values as well. Although Android tablets are pretty cheap, and wiring up to my car just to run Torque wouldn't be difficult.

I definitely don't want to spend days getting things running smooth in my garage just to take it to another shop. I'll consider if something like an EcuTek tune is better for me. There definitely seems to be more support for it.

Switched from the Edelbrock CARB v3 tune to the Delicious V21 tune and the car's idle behavior is much better, with no more surging as you clutch in coming to a stop.

I haven't explored much of the top end of the RPM range but things feel pretty smooth at the low end for daily driving.

Same experience here...nice and stable.

What's the CARB V3 file name? I'm still on a CARB tune (ZA1JB01D_6B83D0_EForce_EO.bin); still experiencing the mid-range hesitation ever since it was flashed from the original tune. Hoping Edelbrock will release a version that fixes that as I want to stay with the CARB tune.

ECU_DongleID_EForce_EO_V3.bin

And verbage from Edelbrock on the changes

We noticed the rpm fluctuation seemed to follow a sudden ramp in exhaust cam timing at a specific range in engine load. We softened that ramp slightly an are hoping this will address the “bucking” issue you are experiencing. As for your fuel mileage we do not understand why your BRZ is performing any different from other vehicles with the same ECU version at this point.

We're on CARB V3 also and still have the bucking issue. Can't seem to figure it out but glad I'm not the only one. I really wonder if it's something mechanical with the supercharger or the intake setup. It just isn't smooth at all. But still no MIL or anything.

i don't think so because it was fine on the initial tune before the EO one.

I assume edelbrock knows about this issue and is working on it? Be nice to see a response from them here...

Likely answer is it's a side effect of having to tune for emissions controls.

Yes, they are, but not enough folk are providing data logs to actually change the CARB tune. They don't know if it only affects a small minority, or more. They're addressing them on an individual basis. One of the factors is that many people are just buying tunes so they don't get as much feedback on the CARB tune.
