You can't log real knock with Zietronix, either. The only real knock is calculated inside the stock ECU. No knock buffers, adapters, extera sensors, or even applications that log the stock sensor's voltage tells you anything about real knock.

Real knock is corrected by knock retard, or knock correction, which pulls specific amounts of timing. The ECU already has complex lookups and algorithms to calculate this. This is what real knock is and this is what you want to log. Why do you want to try to manually interpret one piece of data, like a knock sensor voltage, and correlate that into real knock, when the ECU is already doing that and has been designed and tested by the Mitsu engineers over years of research?? The software being developed for ECUFlash should be able to log this knock retard value, since ECUFlash communicates with the ECU.

NO product that doesn't communicate with the ECU can tell you where the ECU is pulling timing (knock retard) due to knock and how much timing is being pulled. Voltage fom stock sensors or additional sensors is just a waste of time and money. But, if you think you are seeing real knock, all the power to you.

The only product that I have ever seen that can do this is DSMLink. Why? Because DSMLink does exactly what ECUFlash lets you do. You control a stock DSM ECU and their logging capabilities logs directly from the stock ECU.

Yes you can log knock.

This guy did it by connecting a wire to the ECU. That green line that you see in the screenshots, that is the knock being logged. Sorry, but you are wrong.

 

You forgot to add the price of a lap top to your calculation Good luck carrying a lap top with you wherever you go so you can log whenever you want. With my LM-1 I can log whenever I want and wherever I want since at the push of the record button. No need to carry a lap top with me all the time.

Another feature of the Innovate is that it give you an error message when the wide band sensor is out of calibration. With other widebands they keep on measuring the AFR and give you wrong data. With the innovate you know that something is wrong. You can either re-calibrate by free air or from the button on the recording box or get a new sensor.

Does the Zeitronix do that?

 

Who much is Innovate and can you put a pic of it. Sounds good.

 

There will always be trade offs. I have had and used both; compared with the zeitronix 74 sample/sec the LM-1 the averaged 12.5 sample rate is pretty useless for logging timing, too many events get smoothed out. Now for the cost of the laptop; still needed to use ECUflash....

 

Damn,

YOU CAN'T LOG KNOCK by just hooking the stock knock sensor to the user input on Innovate products.
People do it but that doesnt mean anything.

ONLY ECU+ knock circuit and Vishnus Knock buffer can log knock.

Also, like Jorge T said, Innovate products only log at 12.5 sample per sec. That very weak. Your engine spins somthing like 200 times per sec when @ 6000 PRM. That mean you Innovate only logs about 6% of the engine activity @ 6000RPM.

Also, stop saying "oh you neeed a labtop". If you gonna use ECUFlash (Or most other form of user Engine Managment), then you need a laptop anyway.

 

Nope. Thats not right.

Your talking bout loggin Timing, and weather timing is gettin advanced or pulled, depending on the knock retard or knock correction.

Im talkin bout knock. The stock knock sensor is a microphone and if you take the signal, clean it up and amplify it, you can use it to LOG KNOCK, reguardless of the knock correction. The ECU+ and knock buffer do just that, clean and amplifier the sigal so you can Log it.

Your right about the timing, I can't log my timing. BUT I can log knock.

 

No, that's not what I am talking about. Loggin a knock sensor voltage is not logging knock, it's logging knock sensor voltage.

I don't want to explain it again, but if you think you are logging knock, then you should be fine with that.

When I said you need a lap top, I meant that it is TOO cumbersome to carry a lap top with you ALL the time in order to log. Believe me I tried logging with a lap top with my Xede and driving at the same time. It is a PITA. With the Innovate the LM-1 unit is right there attached to a suction cup on the windshield. Press the red record button and you are logging. Press it again and you are done.

I do TWO 3rd gear logs per day. One on the on ramp to the freeway on my way to work and one on the on ramp from work. Imagine what a PITA that would be if I had to carry a lap top with me EVERY DAY.

Do you have your lap top in the car every day? Would you leave your lap top in the car like I leave my LM-1 every day?

All I am saying that it is a hassle to log with the Zeitronix. That is all.

 

And all we are saying is that if your using ECUFlash you have to deal with the "hassle" of a laptop to get a MUCH BETTER data sampling from Zeitronix.

 

I never said that the LM-1 logs timing. That is news to me if it does. I know for sure that it logs, AFR, RPM, and boost. That is what I currently log. I also read that it logs TPS and Knock. Evo-Kid says that this method is not accurate. I cannot comment since I did not try it.

 

If you do not have either unit and you have an ECUFlash and you know that ECUFlash is going to integrate Innovate into their software, which one will you get?

 

Until I see it done, it's about whats more important to me. Your talking to someone who has has an innovate LM-1 and the XD-1 with LC1 so its not like I'm blind to Innovates products. But I know if I am using ECUFLASH and I WILL need a laptop to use it then I would lean toward the item that gives me a far more accurate assesment of whats happening in the car. Zeitronix does that. Not a pissin contest, I like Innovate its cool stuff.

 

 

A knock sensor (aftermarket or stock) is just a microphone.

Yes logging just the knock sensor voltage does nothing.
Thats why you need a knock buffer or some type of circuit to process the voltage.

Yes, you were talking about is knock correction and timing. DO you even know how a knock sensor works???

It's just a microphone, it listens to the motor. When there is knock or det., there is a spike in the noise. This is knock.

The stuff your talking about is what the ECU does when it sees that spike. The ECU can see the spike because it doesn't just read voltage. It processes the voltage (just like the knock buffer and ECU+), so it can see these spikes. Then it changes timing using knock correction.

If you dont understand, go read a book.
