Custom E30 Tune & Data-logging

BMW DRIVEN · 08-27-2021, 03:33 PM

Custom E30 tune was reworked and now complete. Let me know what tunes you are running and if anyone has upgraded their hpfp.

Yeah, it doesn't really make sense to get a custom E30 tune with stock HPFP. But hey if you enjoyed the process for $600, it's your money

Also, operating as close to the HPFP limit as you are (well actually, you already exceeded it) is problematic for a number of reasons, especially without an ethanol sensor. Variability in pump gas or E85 content between gas stations or fillups, or just imprecise mixing (by increments of less than a gallon) can easily push you into hull HPFP crash territory.

Yeah, I agree with the variance in gas. I do test my E85 every fill up, but for 91 who knows. At this point all I can do is trust Cary Jordan when he says we are nearing the limits of the hpfp and can't push it any further. If I run into any issues I'll just run the E30 OTS map.

Get a HPFP. You can even max out the fuel pump on regular gas

Yep, it's on the mod list. Are you running an upgraded pump?

Cary’s a moron.

Instead of him being straight with you and saying that the E30 OTS maps will max out the HPFP and that a custom E30 tune is worthless on the stock HPFP (which you could have figured out with some research), he’s happy wasting your time and taking your $600.

Why are you accepting a tune where HPFP dips below target? Does it do that on OTS also? I dont have access to E so I am running WMI (FYI).

Being new to the N55 platform and not as educated as I was with the N54 motor, I would have just ran the OTS map. But I will say that my custom tune does feel stronger and more dialed vs the OTS map. Is it worth $600 bucks? No, but I didn't mind spending the money and go through the custom tuning process.

Yes, it dips below target but still within the safe range. I have not had any misfires, stuttering, or any issues whatsoever, so I feel okay about it for until I upgrade.
