On the stock turbo you'd be hard pressed to need anything that small. The m4 gts runs the same plugs and coils making near 500 whp and still is fine on the stock gap. |

Sadly the new Bootmod3 IOS version 0.40.022 is unusable. All the gauges are running crazy in dashboard. Can't make logs for now. Anybody has the same issue? |

according the custom cary jordan map I was running, It should be rich. Now I don't know which problem should be taken care first. Plugs? HPFP ? or maybe LPFP. Dangle will be arriving by the end of the day. I will pump gas to full tank (eliminate fuel starvation) and try to do some pulls with the new 0.028'' gap first. Meanwhile checking if HPFP pressure still drop like crazy. Update Logs later. |

I think we can move to next issue now. Driving around https://www.bootmod3.net/log?id=6363...90c66e2106cbe9 3rd Gear WOT https://www.bootmod3.net/log?id=6363...90c66aae9556bf I know fuel pressure crashed like mothertrucker! It's not like I don't want to rev all the way to 7k rpm, I think throttle closed by itself at 5.5k ish. I left gas pedal as soon as I hear burbles(brrrrr) from exhaust. I assume no more fuel incoming. @AmuroRay Last edited by ericlr1225; 11-03-2022 at 05:37 AM.. |

Fuel pressure drops could be due to colder iats as it is winter now, this colder iat means denser air which means more fuel required. So the HPFP can't keep up.

All I see is a car with fueling issues. Everything else looks great, fantastic really, at least to my amateur eye.
I dont see what you mean by the throttle closing by itself. Throttle was 100% the entire time accel pedal was 100% with the exception of a teeny tiny dip as boost built (normal and expected). I'm guessing what you felt was the car simply running out of fuel pressure and struggling to pull beyond 5500rpm or so. Here's my car on stage 1 - HPFP requested vs actual....

Tomorrow I will change all new coils to see if it's the reason which caused this fueling issue. Hope it won't get too far. Really don't want to upgrade HPFP/LPFP/EPKS just to run a stage 2 acn:

very beginning of the log has a section of WOT. the last 95% of the log is just random noise.

sorry for late reply, are you asking if the HPFP in my log is upgraded? No, bone stock. Only mods are intercooler, charge pipe, stage 1 BM3.

enable long term fuel trim (LTFT) and log again.
your STFT is high, indicating that your car is pushing more fuel to compensate for something. possibly the fuel you use is really high in ethanol? or you've got a vacuum leak? or your MAF or o2 sensor is malfunctioning?

MAF o2 are working well, daily drive fine, no cel, no any codes. HPFP hit target during daily drive. only dips hard when WOT. Already changed back to OEM plugs and all new 6 coils. flashed back to stock tune. https://www.bootmod3.net/log?id=636d...90c66e2106ec36 https://www.bootmod3.net/log?id=636b...90c66aae957259 It seems no one in this forum can figure out what exactly happened. So I ordered the entire fuel system including EKPM. I'm gonna change one at a time and do logs to see what exactly it is. |

Car is 21k miles, it's too new, generally no way that fuel system is weak like this, sometimes I think if my DME got some problem.
Everything changed afterNGK 1 step colder /base map tune from custom tuner. After that HPFP keeps crashing no matter what map. put OEM back in, flashed stock tune didn't get any improvement |

Swap all new OEM Injectors today, did some logs, hpfp crash remain. It looks like has nothing to do with injectors, old ones are clean as new.
https://www.bootmod3.net/log?id=6381...729b3bae0d2ac3 https://www.bootmod3.net/log?id=6381...0b43f7e1943e2c STFT high, some knocks, HPFP keep crashing. Right now, brand new sparkplugs, coils, injectors. The only piece I haven't put back to stock is 3.5bar Tmap sensor which I bought from Amazon https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 |
