OFT vs. Ecutek

the load limit you can't raise? you're correct that you can hack around the problem, or you can just solve it directly. it's up to you. you can hack around the load limit too, old-school 16-bit wrx style... if you want to. but you don't.

these are real, hard limitations that matter. they matter to a very small subset of the community, but they do matter.

And swapping to an antiquated SD system isn't hacking around the issue? In all seriousness, at what HP level does the load limit come into play and what percentage of BRZ owners will have this issue?

Eta on vortech support?

Thanks

the limit is 4g/rev. do the math.

I don't understand why you think this will be a limitation.

Pretty soon. We were originally shooting for the end of this month. But right now we are testing the Phantom ESC which pushed the schedule back a little bit. Couldn't do it the other way around since the ESC only takes minutes to install vs several hours for the Vortech.

As per my datalogging process I needed a raised load limit and a maf circuit high voltage DTC turned off at high rpm in 3rd gear In cold weather with my 3.125" pulley (~12 psi)

And that can be done with OFT via RomRaider as well.

the load limit as defined in romraider now doesn't actually do anything, fwiw. at least that's what ecutek says, i haven't experienced it myself. it's very high, and most will never hit it, but it's there.

Which brings us back to the question, why do people continue to assert that there is a limit with a MAF setup when clearly it's not an issue for the overwhelmingly vast majority of people? This isn't me trolling, I'm seriously curious why this keeps coming up as a reason ecutek is a superior option over OFT?

But if you hit the maf limits you then need to alter your maf tube or go SD.

Honest question, if OFT supported hybrid SD would you experiment with it?

There are a few MAF limit tables in the stock ROM. All of them can be adjusted upwards to the point where there is no software induced limit. Same goes for the MAP sensor. But once the physical limit of the MAF sensor is reached, you just increase the housing size slightly. As long as we aren't trying to make huge increases to sensor overhead (i.e., more than 50%), I believe this approach is more attractive and functionally superior to going with an SD setup (hybrid or otherwise). SD setups were made popular back in the day when the MAF sensor element (not housing) were huge, restrictive and sometimes delicate. That is no longer the case.

two words: superiority complex

because eventually you'll run into it, and it can happen a lot sooner than you think depending on what setup you use (i.e. JR sc).

i don't argue most people will care, but for the 10% that do, it does matter. anyone looking to make more than 350whp will need sd with a 3" maf, at least every car i've tuned to that level has. the alternative is to go bigger than 3" and use a reducer to the throttle body. not exactly an elegant solution.

if you want to assert superiority based on your tuning suite, well that's just pathetic, but you wouldn't use that argument. you'd just say 'custom maps' and the argument would be over.

and how 'antiquated' is an evo x? they use hybrid setups stock.

i'm a huge fan of OFT. i think it's the best option for 90% of us. but to pretend there aren't drawbacks for the other 10% is disingenuous.
