Fuel pressure is normal in the logs attached... Where is the log of it dropping?

Been running T6 for a few days now on map5 with the N20 TMAP and so far things seem to be running well overall (no codes, limps, or any crazyness). The one thing I'm currently wondering about is the IAT resistor mod. With a BEF, do I still need this? It seems as if AvgIgn actually increased overall when I added it back in. I'm not seeing quite as much boost as I'd like, and I'm wondering if this is the cause. Logs coming shortly, probably on the commute home today.

Not needed with a BEF. Not really sure it was ever >needed< - more just a safety precaution at the expense of very few horses.

Hi Terry,

Today I test ISO7 T3 again with E45 and PI on 4th to 5th gear. I set all AFR bias to 50. However my fueling went to open loop right after gear shift and HPFP pressure was dropping. (Log attached)

*i have noticed to avoid open loop, my 4th gear trim must be above 25 before gear shift. If it is below 25, it must go to open loop after gear shift.

Could you please provide advice how to overcome trim stuck at 25 and FP_H drop? Thank you for your valuable time and help!

If fuel pressure is dropping you need more port injection or meth flow.

Hi Terry,

Thank you very much for your quick response. Here is a new log (same fuel E45, same boost and same port injection) (BMS PI controller)

I set all AFR bias to 70 instead of 50 for more fuel, you can see the trim goes to negative, but fuel pressure still drops after gear shift (4th to 5th) and car went to open loop and trim was stuck at 25 after gear shifted

Could you please help, thank you for your advice!

Just got the JB4 app update, should we worry about the new settings at all? I'm using the FlexFuel wires and have WMI hooked up, but no PI as of yet.

Thanks

Got some Map 3 logs today, things feel pretty good overall, but sometimes it seems to just cut/hang at high RPM right before shift. I also noticed with the most recent iOS app update that sometimes it seems to lose the connection and the logs go missing, so I don't have all the data I thought I did.

Oh, also, what's max boost target on map 5? 18psi still? Does it increase with the N20 TMAP sensor?

The N20 sensor doesn't give you more boost, but the stock 2.5 Bar sensor maxes out and 21 PSI and cannot read higher boost pressures. If you plan to boost more than 20 PSI you should upgrade the TMAP sensor.

Yes, I know this. I'm asking if the target on map 5 increases when using the N20 TMAP sensor, since it is able to read more boost overall. Sorry if that wasn't clear enough for you.

Just curious as to why you have dwp at 60 instead of default 80

after 3 years of adjusting my jb4, from my own adjustments and from Terry and other tuners, that's just where it ended up lol. I have no idea when it was set to 60. I'm going to flash back to my stock tune and see if I get any improvement on these logs as my current BEF is still extremely unfinished by Ricardo, then Dzenno will start building me a BEF.

The DWP setting of 60 or 80 doesn't matter much especially on the N55.

Then whats the point of it on a f series? Default is 80 so what happens when i lower it 20 at a time? I just lose responsiveness?

It's just a setting that has to be defined. Since the N55 turbo makes ~3psi with no WGDC at all where you set it has no real significance.
