Nice! Any thoughts on a race fuel tune for track days? That turbo would be great for that.
-
It should run, just not safely. It would definitely idle at least unless it's cold. But I forgot about the fuel trim limitations.
-
Are you logging flkc? Its possible you arent seeing knock in logs because flkc is already pulling the timing. If you log that, it will tell you where the timing is being pulled. Or do a reset and log a pull once iam hits 1.
-
Yea, but you want to catch the knock on a log. You need to know where it happened before you start pulling timing. Lv gives you too low resolution.
-
I cant believe im writing this, but we should probably stay on topic in this thread.
-
Any other symptoms? Rough idle?
And my usual first question...stock air filter?
-
When you reset the ecu, you need to give it 10 or 20 seconds before starting it. I think it's just rebooting, but it will just crank until it's ready. I just wait until the seat belt chime goes off to start the car.
I'm not too sure what's going on. If it was a major vacuum leak, you'd be pegged at 15% in the af learning areas.
-
That's a lot of knock.
-
Without a tune, you'll simply kill your gas mileage and run ridiculously rich. Why you'd waste your money on 30% more fuel for no reason, I don't know.
-
I should also specify that i get an occasional knock, but never learned knock and never during a pull. Its always during a shift or when i start accelerating.
-
I wasnt implying that. I have a stage 1 tune. No point in pushing it. So yes, in a sense, it is anemic.
-
It's been so long since I've seen any real knock in my logs, it's hard to remember.
-
Then maybe it shows up as both? I haven't logged with them in a while. I usually just do knock sum. I can tell you for certain that if I do a pull and get knock, it will show up on a learning view afterwards.
-
Feedback is usually tip in, shift knock, noise, etc. If you do a 3rd gear wot pull, any knock you get during the pull will be flkc.
-
Feedback is a knock event, its literally when the knock sensor hears a knock. Learned knock is the ecu pulling timing in an area because it has heard feedback in the same area multiple times. It says "damn, it has been knocking here a lot, lets pull timing since its obviously a trouble area" so that next firing order doesnt actively knock and trigger more feedback
But a single knock under the right circumstances will trigger fbkc. Feedback does not learn and is generally for any knock that does not fall into the fbkc category. The ecu will decide whether to pull timing for feedback or fine learning when there is knock.
-
I type too slow on my phone.
-
Flkc will show you timing being retarded from either a current knock event or a previous one that it learned from. Knock sum is just a counter for knock events, so the number will just go up every time there is knock.
-
1byte and 4byte. I think they will give you the same information though. Just make sure you are also logging knock sum so you know if you are seeing timing reduced from learned knock or an actual knock event. I use FBKC.
-
Must be.
-
I don't know that there's anything wrong with it.
-
I would never consider an off brand for something like this.
That gates kit for $250 is legit. It's sealed in a gates box and a good kit. I have the box in front of me as I type this.
-
Wow. Even more impressed that youve figured out how to modify it! Any thoughts about releasing your own kit?
-
Good point.
-
Except that the Cobb ots map is for stock injectors and intake, and the A/F learning is -7 in the +40g/s. Although they do tend to fluctuate occasionally. Maybe take some more learning views and see if there's a pattern.
Mine bounced from -10 to +10 in a day at one point and then fixed itself a day later. I started a thread about it but never really figured it out.
