and what about the stock restyling tunes, with -40degress of ignition timing when you mash on the throttle even on high loads, you think is different? you think subaru gives us engine smashing tunes on porpouse?

If you think that all that is happening is a bit of ignition retard then there is no point discussing.

what else happens then, when all you do is altering the <0.2 engine load column of the ignition timing base table?

sure a bit of fuel of those particular cycles goes to the exhaust, but that happens also when the stock tune commands a retard in ignition timings

i'm all hears

but apparently you do not want to discuss it

A backfire is definitely going to have a pop and a lot of bangs...

You sound like a fuckboi.

tomm.brz · 07-26-2019, 03:00 PM

How could you tell that?
I am a fuckboi cause i want to help a guy having innocuous pops in his car for fun?
i tuned more than 37 ft86s in Italy and no one broke his car in the last 2 years and half, and half of them track them or make drift, and everyone of them has some kind of oops availability, either with a touch in the Ecutek app, or VSC button

RToyo86 · 07-26-2019, 03:05 PM

A catless header with no muffler. :o I can't imagine how that would be tolerable to drive.

As long as OP understands it'll likely destroy/foul O2 sensors and run the risk of burning up a valve have at er

Or washing down the cylinder walls with gas so there's no oil left to lubricate the rings.

As for backfires... no one really wants a backfire on purpose.

Running insanely rich with only DI washes the cylinder, not some stupidly light brefly ignition retard

KBandz · 07-27-2019, 02:17 PM

I put in manual mode and then it gives me complete control of each gear. I usually let the rev hang at 4K but no pops, I get burbles but none actual pops.

How do you make your car like it has a poor tune, make it pop and bang.

Why are people so stupid?

Same reason marketing trumps good engineering.

I might be a bit late to this post, but I also had this issue, turns out the ECU was not switching to the B map for a while after flashing. just had to go for a bit of a drive then turn the ignition off for 15 mins or so and it was sorted.
Its something to do with it taking a while for the ECU to relearn its AVCS parameters or something.
FYI you can get a nicer pop going of you set the overrun fuel injector pulse width to 2ms or so
