OFT vs. Ecutek

i've never tuned one, but i do believe @nelsmar hit 5v rather quickly on the JR kit. again i havent experienced this myself, but based on my experience with a 3", and looking at their maf tube, it seems very reasonable to believe.

This is good info for me because if I ever do pull the trigger I'm going for a smooth operation not big numbers.

I would like for my internals to see 100k inside of my motor.



Evo uses a hybrid SD/MAF so what about other cars.... GTR, STI, and GTI? I honestly think tuners should use whatever works for them. Long as the user experience is good and everything is running right.

Can't find the info, but I wonder if the FRS factory tune is a MAF/SD hybrid...

Yes
Soft rev limit
Launch control
Flat foot shifting
Rough idle fix
DI Seal fix

Just check you ROM type supported

Why would the FRS be any different than the BRZ?

It only has a MAF stock. That's why there is all this talk about ecutek based SD conversions and wether it's necessary or not.

The Frs/brz? They have MAF/MAP sensors stock

If you knew then why did you ask? I can only assume it was to make someone look like an ass. Congratulations

No, you read that completely wrong. I am trying to determine if the FRS/BRZ uses a MAF/SD hybrid tune from the factory. I'm not sure if the MAP sensor is for a limp mode if the MAF sensor is faulty, or if it uses the MAP sensor for fueling at high rpm. You were the one who jumped down my throat.

Obviously there is intention lost in a text based means of translation. I apparently reacted to an assumption that was faulty just like you assumed I was jumping down your throat (not intended). Regardless, it's quite apparent that I do not have the knowledge set to answer the question but why would several of the aftermarket ecutek FI kits include an MAP sensor if it used one stock?

Possibly because of the same reason people swap to a larger diameter MAF tube (the factory parts are insufficient to deal with the increased airflow).

TLR, I need to stop talking about stuff I don't have first hand knowledge about.

The FRS/BRZ has a map sensor that can read a few PSI above atmospheric, so boost in the 4-5psi range I think (someone correct me if its higher/lower). I'm not sure if the FRS/BRZ uses MAF/SD hybrid, but it would not be out of the question since the cars have both sensors stock and many OEM's use a hybrid MAF/SD.

I have noticed that the vortech (possibly the JRSC/Kraftwerks as well) carb tune kit does NOT include a MAP sensor... is this because you can't swap emissions sensors and still get CARB approved? I really don't know, and the info is hard to find.

Hell, if I didn't already have ECUTEK I would have been looking at the OFT because of the price

the stock ecu only uses the map sensor for fueling calculations during cranking. there are some necessary comps (like port mrp compensation) that use it, but generally it's more useful as an iat sensor in a blow-through setup lol.

Good info!
