Yesterday I made a few tests: I burn the actual image again to the ECU (no changes made so far) and drive a little bit around (one time till 245 km/h :D ) but there is still no change at the AF Self Learn value. It stands fix at "100 %" the whole time. :cry: What can I do? Should I do a re...

I know that GRomer copies a lot of chip-solutions from Nissans and other brands! He sells e.g. copies of Horsham Chips for the S14 and S14a (I know of Stage 1, 2, 3 and 3a) with minor quality! Take only a look on his ebay feedbacks what he sells... I know from someone how contacts me that his engine...

did you tick the injector duty cycle in the consult display registers window? "Injector duty" is ticked but not shown as there are no space left for so much gauges. The maximum of 12 gauges is shown as: RPM, MAF, Temp, O2, Speed, TPS, inj time, Timing, AAC, AF Alpha Learn, AFR and Boost. ...

Okay, thank you again!

One thing to the same issue:
If I select AFR and Boost in "Operations - Select Display Gauges" there are also no Updates to the needle as the values itself are updated.
Perhaps this helps to find the bug.

Thanks for quick fix! Now I don't get the error message about the translation file anymore and I can read, which question NIStune asks me. :D It asks me if I want to merge my readed bin with a base-bin because some maps are not ok in it. After the merge and saving the bin the question do not come an...

One thing more I found: If I open the AFR wideband tracer there is no more the possibility to chose between "actual", "minimum" and "maximum" for the shown values. The good thing is: I am now able to open more then one window with AFR wideband tracer and can chose in on...

Thank you very much for the new release. I installed it (with the new adress files of course) and when I start NIStune there are 2 error messages and when I try to open a bin I where asked a question where I do not see what question it is. :D NIStune itself looks very well at the moment, no problems...

I guess to prove the bandpass theory just get a mp3 file from that site i linked before and play it back through winamp and adjust the EQ.. There is an easier solution! Get the freeware Audacity here: http://audacity.sourceforge.net/ Install the software, load the mp3-file and go to "Effect - ...

I have found some websites again with some informations about engine knock: Engine Knock Theory Listen to your Knock Sensor Knock Sensor Sounds A post from a subaru forum: engine noise vs knock detection Perhaps it will be possible to build an own knock monitor with these chips (at the moment I do n...

I haven't try it with NIStune yet but I use NissanDataScan 1.4. This is the last free version of it. There is a button where you can fix the timing at 15°. Then you can use a timing gun to check if the 15° that the ECU see is 15° in reality. You can use the same data cable as for NIStune. Here is an...

So the conclusion is that I do not come around to do the last bits on a dyno.

A few weeks ago I have asked the same question for my SR20DET. Perhaps the answers are okay for your ECU too.

Ah, thanks. I will look if I can mount the additional sensor in the near area to the original one. Here is an engine knock calculator which says that the 86mm pistons from the SR20DET will produce a knock signal at a frequenzy of 6.7 kHz: http://www.phormula.co.uk/KnockCalculator.aspx Does this mean...

micha ... nothing going on in those recordings however it is where your peak torque 3000 - 4500 rpm depending on setup.. is not so much low load / hi / low rpm driving.... find a hill and a tall gear give it a boot and dont break traction and then listen.. best not done from drivers seat.. get a ma...

Just an update: The solution works pretty good. The most difficult thing is to find a good place for the knock sensor without having too much noise from the head. For my test drive I bolt the sensor onto the intake. Sample Sound: Engine_Sound_S14a_SR20DET_Test1.zip http://forum.nistune.com/files/img...
