Will be changing mine to a better range

Also for the record I checked my error codes. Every single one is enabled except boost control solenoid due to me running evc

Bruce turned off my cat efficacy below threshold code on Friday. It was logging up when on cruise, rev zone had it disabled but it wasn't on my new tune

Fixed!

Let me know when you'd like to meet up to reload your map.

Mick out of curiousity, why would you turn off that code even if you were running an EVC?

Does the EVC have it's own alert system to advise of a max boost limit being breached and then switch to a failsafe mode?

I would've thought it would be best to leave the code enabled incase the EVC fails, or a hose pops off etc causing a boost limit being reached and the therefore you'd feel the jolt of the fuel cut. You'd plug in your tactrix, check the code and reset and then know exactly WTF happened and where to start looking for a fix. You're effectively doubling your safety system and making fault finding easier.

Disabling the code would see you get the fuel cut jolt, log in with your Tactrix and see no code. Leaving you scratching your head.

Also can you advise if you have a Boost limit (Fuel cut) set in your map.

Thanks

Couple of things Bruce

The overboost code is not disabled and unrelated to boost control solenoid

Secondly the evc does have an overboost function but more importantly, its the ecu via map sensor that detects overboost for fuel cut.

Mine is set at 22.8psi, which trips only at the track / drags if I'm flat out in fourth (about 4500rpm).

Edit - also have the secondary precaution of my defi gauges and controller showing peak hold boost an overboost buzzer (and flashing red light )

Hope this and the previous posts helped

Mick I have a disabled CEL on my tune and from what Matt has told me it only prevents the car from going in to limp mode after an overboost, however it will still fuel cut or whatever it does when it detects overboost. I'm yet to actually experience it yet other than one time when I first had the tune and had a boos tleak.

Is that the same thing you are talking about?

[KiDo_Tuning]

this is maybe why some people are having a spit at matt's tunes after looking at LV because they can see it broken down whereas a broader range like GB's will not show the finer load ranges and thus may mask some flkc

Mick

Putting FLKC into such a wide range has the engine running through the zones for longer hence the ECU can self learn on its timer to go back to zero. ECU self learns by the time spent in a specific area etc. So if you had knock at 6000rpm at under 1.3g/rev for example, it might takes MONTHS to spend enough time in that region where the ECU uses the FLKC Advance value to try and return to 0 etc

Pro-Active FLKC is better for safety than Reactive FBKC

Try going for a twisty mountain road drive, getting a CEL halfway up the mountain and no where to pull over safely. Boost cut is a very unique experience... is there really any doubt? Also, for those who do not have a Tactrix, $25 or more for a reset fee from a mechanic...

Also, open any of the earlier models ROM's for 05 onwards DBW and find me the P0244 CEL to turn off

Here is a Dyno Tuned car with the D Range in negative affecting the high rpm fuel pulsewidth as previously discussed(wideband was showing 12.2:1 on 16psi boost)

Owner left with a CEL flsh on Knock detection patch, which also allows him to check IAM as well by Press & Hold the clutch Pedal and then press the cruise control "resume/accel" button with Cruise Off. CEL flashes once for IAM at 1.000, 9 times for IAM at 0.500 and 17 times for IAM at 0.000 but also does inbetween(IAM at 0.875 is 3 for example)

Also have this one which was a stock standard MY11 STI Auto which came along with the above car for a tune tweak

Put it this way, would you have have knock and be running lean and generating massive heat or knock and know it is safely rich?

Try setting boost cut at 12psi and you will quickly get the cut but no frustrating CEL lol.

all that knock those lv's could be caused by the fuel being pulled out of the d range in the a/f while in open loop?

Exactly. I have had a tuner tell me it was not possible...

$25 for a reset ECU. I can see why your mate Sharpie is loving you...

On another note if I had boost cut on a twisty mountain road, I'd already be both pretty worried and pissed. And I'm not sure I'd want to have further unique experiences such as that whilst driving so best the CEL come on, and I get off the mountain safely.

I'm glad I stopped when I did as these unique experiences aren't for me.

I guess each to their own on this one though.
