I shift too hard lmao idk man. Maybe my sound system installer maybe messe it up or whoever installed my HIDS. But all seems well so far. Going to do a drive cycle and see if my CEL comes on.

Lol one case of a car coincidentally having the tune and throwing a CEL and you assume that it must be due to the tune??!!??!!

Scary stuff!!!

^^ I really tried to emphasize I wasn't blaming the tune. Whatever though

^Ya that is what I was getting at. But ALT BRZ thinks otherwise.

The tune is not the issue here.

Check the thread title again. Correlation =/= causation. I'm giving the OP the benefit of the doubt.

Your input was very helpful in this thread - thanks !

Please update your Tune features...

What this flash does -

Raises RPM Limit
Improve Fuel Economy
Adjusts Direct Injection / Port Injection Mixture
Adjusts Caming Timing
Smooths out Wide Open Throttle Fueling
Smooths Timing table
Unplugs Traction Control

Check out my thread for my STG1 flash - it's in my signature ..

I got a check engine light last time I put my stock intake back on because I forgot to tighten one clamp (was in a rush). There was no traction control light. As soon as I tightened the clamp and turned the car off/on, it went away. So I don't think this is true.

Unfortunately, this is relatively impossible. CEL's happen when the ECU reads certain values from sensors. Typically, this is either an "out of bounds" value (a sensor is reporting a voltage that's not within expected spec in the ECU; e.g. cam advance problem) or a predetermined condition from multiple sensors that calculates out of spec to the ECU (One sensor reports one condition that conflicts with another sensor, both are within spec separately; e.g. My CEL. Engine was receiving a lot more air than the MAFS was reporting).

So it's highly unlikely that John's tune caused a CEL. He doesn't touch how the engine receives CELs. And I'm willing to bet the ECUTek tuning software won't allow him to run a part over spec; such as cam advancement. The only exception I can think of is RPM, of course. He can tell the ECU to let the motor rev past what it can handle, but even then. The CEL would be caused by the mechanical damage as a result.

I'm willing to bet he knows what he's doing and it sounds like there was a problem with your evap system.

Psst John - I think you missed the last line that he added to your STG1 description:

Oh ahahahhahHhhh ;)

I turn my trac and slp off....damn thing turns it's self back on and wont stay off! it's like my passenger window switch & trac button conspire against me when I'm not around.

I'm not sure if it's normal for it to just turn back on and I'm not that far into the owners manual yet. "It's a real page turner" though.:brokenheart:

well the trick to keeping it off is to turn on vsc sport then press and hold traction control for like 5 seconds. That will shut it off until you turn it back on or shut off the car.

HAHA it wasn't the tunes fault that I'm and idiot!
