Hey Mike, so automatic transmission are not affected by blowing di seals right?

Or is because you have actually changed your shifting style, which you also posted about?

I'm curious about the shifting too. I have the injector fix but can induce a knock sound if I shift aggressively and apply throttle early before the clutch is fully engaged (slipping the clutch to smooth out the shift) . If I wait until the clutch is fully engaged and then give throttle then there's no sound.

Yeah I'm catching it every once and awhile on my usual 3-2 downshift, passenger noticed last night, I'm trying not to think that the sky is falling and it's just an intermittent backfire or something else harmless, can't determine if it's from the engine or not and definitely not the firecracker vids people post up revving in neutral.

12/12, no track time, MT, 21k miles.

i also suggest reading the ecuflash thread - @stugray has posted a detailed guide for new users where i also added couple comments.

it is a smart move if you have free tunes or if you can tune yourself, or if you have a tuner who would be willing to tune with it. it definitely is if you already gave a tactrix cable.

If you're going to stay NA or @shiv's FI options (ESC and Vortech) is what you'd be willing to buy - then OFT is another good option for the money, considering support you get and discounts for other products. I would probably get his whole package if he picked a rotrex kit instead of the vortech.

i might end up buying ecutek when i go FI though as few tuners around me would only use ecutek. And the opened tuning community, presented only by @jamesm (at least at this moment he's the only one willing to share his tunes i think), also converted to the 'dark side' and uses ecutek.

^^^ IMO

I just want the ability to flash the latest factory calibs (since the dealers work.) One day I may fiddle with tuning,reduce closed loop, work on knock, etc, not interested in adding power just reliability


Anyone notice how long it takes to warm this engine up in outside single digit temps? Can't be good for the engine. Stuff like that I like to work on when tuning, but its been a while.

I thought there was a timer/delay you can adjust in the ECU for this?

Possibly. Currently on the factory tune though so no adjustments have been made.

I think it may be that the sensor is still reporting the clutch as pressed in even though it's beginning to grip the flywheel. So it's running timing for a no load situation when there is load happening. Once it thinks the clutch is engaged it adjusts the timing.

Although I thought there was a transient timing adjustment made when the clutch is pressed in, in anticipation of a shift.

Maybe someone more knowledgeable on tuning can chime in.

My old brain remembers seeing this in a MadSB post.


When spring comes I hope to make a pure anti EPA, anti-street racing tune. Technically they are called track tunes (that's what Mike has now only with FI.) Its a tune that says "screw and extra 5 hp and screw the EPA, I want reliability.) I'll share, but its going to be a while.

So basically we pretty much have to wait until the DI malfunctions and those with FI are pretty much screwed. Great.

For those with a good FI tune I think have less to worry about, the professional tuner logs I've seen show much less tip in knock than stock.


You have to remember the factory tune has all sorts of stupid regulations it has to pass. IMHO someone tuned by say Delicious won't have a problem.




That is in less the root cause is a slow clutch-in switch, that's probably the ugliest scenario I've seen posted yet.


Congrats you are a member of the Dallas I mean 2012 FR-Z buyers club.

Great forum, I knew a budget solution would pop up eventually. I thinks if you have a 2012 build a $200 tatrix cable + the above would be a smart move if you have a windows laptop.


Opinions?

Colby's Ecuflash beta works fine. Flashing the 01C factory rom to an 00C car is trivial, provided you have the rom and the correct definitions in ecuflash. Flash takes about 90 seconds.

The ways this can go wrong are: low system voltage, bad electrical connections, software and definitions not set up correctly, interruptions during flashing, etc. With just a little practice, the process is painless, fast and easy. If you are starting from scratch, it is certainly possible to fuck this up.

Speaking for myself, I would much rather show someone (with a certain minimum level of tech savvy) how to do this than try to write up a completely robust internet howto (sure as hell there will be some gotcha in Win X.y that I don't know about, etc.).

Ecuflash and OP2.0 is *all*over* the WRX and STi world. If you know guys who tune and tinker with those, chances are certain you can find someone who knows the ins and outs of Romraider and ecuflash (but they will need the less easy to find ecuflash beta to flash an 86).

The DI seal failure happens with no warning, but we have enough miles on the 2014 that we should have seen the failure by now if it were going to happen. We didn't average many miles between DI seal failures on the 2013.

Mike, I'm seriously considering the JR kit. How hard have you beat it up? Some clubs have 15-20min sessions, mine are typically 25-30min. Any cooling issues before/after adding the oil cooler? I've already had the DI seal issue and repaired around 2000mi ago.

It takes forever in ANY condition...
