Re: Jagged injection

Thank you for reply. I done this on track. MAP is a little jagged also in the next gears, but there is not the same behaviour, you can see log and calibration attached. It's seems like to me that there is some compensation in fuel. Could be? Dwell angle can do this? I have 13.3 Volt at WOT Thanks

Jagged injection

Hi, K20A2 with PRA ECU and Kpro 4 https://s19.postimg.cc/j6yagjhbn/INJ_jagged_2018.09_Imola.jpg Do you have any advice to understand the cause of this jagged behavior of the injection, for example at 3:02 The consequence is that the AFR remains rich for 2 seconds (AFR on ELD, 0 V -> 9 AFR, 5 V -> 19...

Re: Rich for long time after changing gear at WOT

I want to show you the following images with some extra lines, to show you that there is a different AFR to the same RPM. It happens after the gears change. That is why I have hypothesized problems with the tap-in parameters. It does not always happen, but often. Based on the following pictures ther...

Re: Rich for long time after changing gear at WOT

Thank you very much for explanation

Now, the original question: looking at the images above, AFR rich for 2 or more seconds when changing gear, it's normal? or I have to calibrate TPS Tap-In parameters?

What's your opinion?

Re: Rich for long time after changing gear at WOT

Yes, I read documentation, but I don't understand.

Documentation not explains what means TPS Fuel stopped and TPS Fuel moving.

Also, I don't undestand if a higher rate of change is related to a faster opening of the throttle, or the reverse.

Thanks

Re: Rich for long time after changing gear at WOT

Can you help me?

Another question, could you explain me Throttle parameters -> Tap-in -> TPS Fuel Moving

How to read "Rate of changes" and "compensation"?

And, what are "TPS Fuel stopped" and "TPS Fuel moving"?

I read documentation, but I don't understand

Thank you
Don

Re: Rich for long time after changing gear at WOT

thank you for reply, I haven't seen it

I use openloop in my calibration.

But, I would like to understand,
if you suggest to change Throttle parameters to correct this behaviour,

I would do that if this rich period can compromise performance, in your opinion.

Re: Rich for long time after change gear

Hi, somebody can help me? Just tell me if it's normal or not. Here other tests, I tried with the wideband on analog 0 (AN0) or in the ELD input. But I can not get a constant behavior of the A/F Ratio As you can see from the pictures, during tests, the AFR is ok for the first gear, then, after change...

Rich for long time after changing gear at WOT

Hi, K20A2 with PRA ECU and Kpro 4 in the attached log, 0:28 and 3:18 Why injection (ms) has this behaviour, only sometimes drop after 2 seconds after WOT, or jagged This cause my afr to stay rich long time, it's normal? My tuner cannot set fuel in openloop without this strange and delayed correction...

Re: knock problem at low rpm

thank you, sure I read this. I've read that k.control is depending from the noise detected from the sensor. So, noisy cams and spring valves can incrase k.control? Anoher question. Which is the sense of positive value in the Knock Ignition Limit Tables? This positive value are never considered. Only...

Re: knock problem at low rpm

Thank you, if you can help me by taking a look at the map. I would understand if I have to act simply by software or, by the log, it can also seems hardware. I also have another questions: 1) Is it normal that double springs supertech 80psi and drop-in cams increase the knock level? from 1.80 to 2.1...

Re: knock problem at low rpm

Thank you for reply, could you kindly have a look at the calibration, to know where you think is the problem?

Even just an indication would be helpful

Thank you

Hello, I would like to ask for help for knock detection with new calibration of my Civic eg swapped K20A2 KPro v4 ECU Pra KManager 4.3.2 I recently installed new drag cartel drop-in cams, 410 injectors and supertech double valve 80psi So, my tuner has done new calibration. I saw thousand of knocks o...
