    2µF Suppressor, what type can it be or must be?

    Mine is a "Gage Pressure Transducer" not a "Absolute Pressure Transducer" but to test back pressure I think it's ok. What kind of back pressure should be expected at 250/260 RPMs? I also have a 4bar/60psi transducer if more low resolution is needed? But it will max out on compression.

    Yes, I see that now, to save the .rfc it has to save individual channels, and I saved both channels at the same time and the only options it gives is .txt, .xls, .doc or images. I didn't know it wouldn't reopen them on the software, I'l do it again the correct way. I have a 20bar/300psi 1000hz transducer I'll wire it up to do the tests you propose.

    It's a HANTEK. Link for software: http://www.hantek.com/en/ProductDetail_2_31.html Go to the download tab, search for "Hantek6022BE Software"

    I've done some oscilloscope logs and It doesn't look so severe as it did on the built in oscilloscope, the delta voltage (its reading from negative to positive) for the 360 step, more or less 3.7v and for the 6 step is 4.2v. 16 mhz +-5900RPM 220kpa.xls I'm not allowed to upload more files Link to other files https://drive.google.com/open?id=1SsyXaEMiMCZRBJrAXUc4HDycpeEHgECC

    Compression test yes, I get around 168 psi(11.59 bar) plus or minus 3 psi(0.21 bar) across all cylinders. Leak down test, no.

    I understand what you are saying, but if it were so linear or so bad by 3000 RPM and above 60 kpa I'd have to increase VE to compensate for the ECU removing fuel calculation and this is not the case, in fact that's the most stable part of the map, and from my testing I get better AFR stability with fuel pressure compensation option for every time the fuel pump changes speed and FPD changes. But this is in my case/experience/logs, can be different for others. If you don't mind me asking, what is your line of work, is it automotive related?

    No, I still run the stock 3 speed fuel pump controller Idle gets 305 to 310 kpa differential fuel pressure Second speed stage has the following condition (more than 2100 RPM and 14% inj. Duty), AUX 9 activates as DFP is dropping below 296 kpa and moments after it gets back to 305 kpa Third speed stage has the following condition (more than 2700 RPM and 22% inj. Duty), AUX 10 activates as DFP is dropping below 300 kpa and moments after it jumps to 330 kpa here yes it gets temporarily overwhelmed, but by 4500RPM it tapers down to 315 kpa and +- maintains it to the RPM limit. look at "ECU Log 2018-09-24 9;18;56 pm.llg"

  10. Hi to all, I'm looking for the 2µF Suppressor to wire close to the coils but I'm not certain of what kind can or should be! Can it be like this? https://pt.rs-online.com/web/p/condensadores-de-aluminio/1085440/ Or can it be like this? https://pt.rs-online.com/web/p/condensadores-de-pelicula-de-polipropileno/3887664/ Ho, and to put some perspective as to why I'm looking for a suppressor, I'm having some misfires on my Z32 has I increase boost above 5 000RPMs, and the logged RPMs are a bit unstable unless I apply max filter (even with max filter I get repeating RPMs on log, ex: ... 5 000, 5 050, 5 050, 5 050, 5 200...), also the voltage on the trigger scope drops from 4.1v at idle to 2.3v at 5 000RPM also visible on the log some times teeth aren't registering well but it doesn't report trigger errors. I've re-gaped spark plugs (no difference). I've replaced the stock coils with new Audi R8 more powerful coils (no difference). I've increased and decreased dwell time (no difference). On the most extreme case, if I insist on accelerator pedal to the floor when its misfiring it completely shuts down ignition and whets the spark plugs for a 4 to 10 seconds the car is all rough and and doesn't ignite well, after a few moments it's ok again. It's a scary sensation as it feels as the engine blew up! Any help and suggestions! Very much appreciated. Thanks in advance.

    Custom trigger setup

    No I don't, I will just measure a stock one and have it laser or water cut.
