[E36 PNP Injector Pulse Width Drops to 0 in Boost]

No.  You could probably do something with a math channel in a 3rd party logging software but not directly in PC Link.

It still doesnt make sense if it was a 100Psi sensor either.  If I back-calculate your voltage based on the 150psi sensor, and you actually have a 100psi sensor, that would mean you had 111psi fuel pressure instead of 166psi.  But the sensor was maxed out most of the time so you had even more than that.  It should be more like 40-45psi.

So two things:

1. Verify your fuel pressure and adjust the reg to something suitable.  
2. Set the RPM limiter to something suitable.

 

Thanks for the help Adam. 

 

I ordered a new sensor (150Psi) so I can verify that my sensor isn't bad, and I can up the RPM limit as well. Next time I'm at the car I'll go over my vacuum lines and see if I can run a line directly from the manifold to the FPR, bypassing any T's I have in place now. I am using the stock FPR and fuel rail (FPR is brand new OEM) though, so it's completely vacuum controlled unfortunately.

I took a look in the tune and realized it is calibrated for a 150Psi sensor. I have a 0-100 sensor installed, and I have the values to input into a cal table to fix it. Is it possible to change the sensor to a cal table within this log? I am not physically near my car and won't be able to capture another log for at least a week.

After going back and forth with my tuner (and eventually being ghosted by him), I'm coming here in search of advice. 

I am having an issue in my tune where it seems my injectors are cutting out as soon as I get into boost. I have replaced my fuel pressure regulator, lines, pump (255LPH), fuel pressure relay & wiring, and have genuine deka 60lb injectors. My tuner thought I was not getting enough fuel to the rail and it was leaning out, but judging by how Injector PW drops to 0 and fuel pressure skyrockets, I think the injectors are stopping fuel delivery entirely. 

I don't know if this is caused by the overrun fuel cut table (or the temperature cut table, since it seems the values there are below operating temp), but I'm not comfortable making my own changes without seeking out advice here first. 

I moved my oil pressure sensor to the fuel line (pre rail), so the Oil Pressure graph in the attached log is actually fuel pressure. 

Thanks in advance!

Yeah that looks like a bit of a mess, I have changed many of the idle settings back to how they should be, try the file attached below and do another log if it is still no good.

 

There is very little advance in your ignition table so that is going to make it feel very flat.  Your lambda looks nowhere close to target.  You also have the boost cut set at 130kpa so you are hitting that a lot.

Thanks Adam! I missed this as I had email notifications seemingly turned off for the forum. I'll try this out and come back with my results, and I'll send it over to my tuner as well.

[E36 PNP Won't Idle (Turbo M52)]

Hey all, been working with a remote tuner to get my M52 dialed in. I'm running 750cc injectors (though apparently I ended up with knockoffs so who knows what they really are), 8.5:1 CR, M50 manifold, and a precision 6262 turbo. 

I pulled out my ICV, cleaned it, and confirmed it opens and closes when 12V is applied directly. The car dies when I let off the gas (even just if I don't shift fast enough) so I've got to pop the clutch to restart it every time, and it barely idles. 

 

Is there something glaringly wrong in this tune? I'm not sure what the issue would be since I know the ICV works and I haven't poked much around the configs in the ecu myself. 

 

Additionally, I've got my MAP and BOV running off the same vacuum tee into the manifold and I noticed today in the manual you aren't supposed to do that. I unplugged the bov line and plugged it (since I was just idling) and it made no difference. I also unplugged the ICV from the harness and that made no difference either, so I'm wondering if it's just configured completely wrong in the ecu. 

 

Thanks!

Unsure if this is related (but adding it just in case), the engine seems really unresponsive as well. If I blip the throttle it takes a second before it actually revs up. Putting the throttle down a bit (not 100%) results in the car bucking and stumbling quite a bit as well.
