Crawford Performance at FRS release event - taps into ECU !

[70NYD]

i wish cobb was more accessable here in oz, tey make some great shit for the 8
is there a better pic of the one in the 1st post? i am still betting that the ecu is accessible through the usb port under the climate

Forget that USB port, go through the ODB2 port (like COBB does)

Some tuners offer torque tunes or fuel economy tunes. Not worth it in and of itself but if you get to pick three tunes, I would pick one to be more fuel economy based. Especially with E85.

50hp would make this car really fast. I'm going to be more than happy to get 200.

Wrong, if you get a proper tune you should have better drive-ability, more power/tq that is smoother and better mpg. The consensus is most people drive harder/faster after tunes resulting in poor MPG, but if you drive normal you'll see an increase.

There are other DI cars that get lots of tuner attention, so they shouldn't be too lost though.

Not performance NA DI cars, I can name only 1 car that comes to mind that's performance oriented, DI, under 30k and not turbo and it's not even out yet.. New Genesis Coupe 3.8. The ECU tuning solutions for the FRS will be a lot of money for little gains. Not to mention buying and installing 4 cams will bend you over.

There is a huge reason why the 2.0T Gen Coupe didn't get DI unlike the 3.8, but still got an increase up to 274hp. Engine Tuning.

Not to mention the port injectors are cheaper and easier to replace.

i would say it will depend on what tuners find once they can get into the fuel mapping logic as far as the split between DI duty and port injectors.

At that point though, it'd be easier to retrofit an older engine.

i can totally imagine tuners working for people wanting big boost and hp going this route

but swapping in an EJ engine will not be a simple matter, certainly not nearly to the extent that it is on past subarus (which came with EJs from teh factory). the newer FB/FA series use different engine mounting and bellhousing bolt patterns.

exactly, although i doubt they would have opted for DI on the 3.8 if it were to impose a limit on them from a tuning standpoint, even with the benefit of reduced emissions and low load fuel consumption. but as you suggested, although big gains have been seen in the DI FI engines, tuners will tell you its a total pain in the ass (from talking to COBB folks regarding tuning a mazdaspeed3 to some 350lbft, 300+hp).

do any of the direct injection engines out there now also have manifold/port injector systems?

also i believe this is on topic

from what ive seen so far, id rather have the base one than either ...except maybe the GT300

P.S. way to quote biggest picture of the year, ill change mine to the url

It is hard to make power N/A with boxer engines though just have to run through the paces, same w/ Perrin. People need to remember the BIG boys in the Subaru game and go from there (also maybe TRD will come through w/ stuff besides kits)

Perrin, the company that quotes their dyno's SAE flywheel bhp conversions as wheel horsepower? No thanks.
