I think that's an estimated upper limit. The car they tested had a PS2. But low 400s seems in line with some custom tune data with upgraded HPFP. I honestly dont think you would gain much by doing a E50 custom tune compared with the new E30 OTS maps on stock turbo, certainly not from a HP/$ perspective. But i think it would be very interesting to see someone with BM3 who already has a Exx custom tune flash this new OTS map and provide back to back datalogs (can use virtual dyno), or even better, dyno runs (wishful thinking). |

this is great.... just curious why E30... I still feel there is a little more to extract from the stock turbo... did he test E50 etc...? or is this just a marketing thing... in a few months we'll see E50 etc...

Stage 1 enough for stock turbo but why not future proof is my opinion. If i ever HPFP it will be a stage 2 or equivalent flow (FX150 is around there). Several options for HPFP out there to consider now. Black friday sales might be key to save $$$.

Eh, I wouldn't look at it as a marketing this because he's targeted E30 for quite sometime now including the B58 both F and G series as well as S55 and S58. I could safely assume that if it hasn't been done for the others especially the S platforms, why would the N55 be the one outlier to the group? Wouldn't you find it odd if an E50 map were made for the N20 but none of the others?

@FastF30 Ah, didn't realize you were MHD. Was just stating from a historical perspective across the line up its consistency using e30. I can't answer on his behalf but I'm sure would could come up with a number of reasons such as demand for e50 vs e30, support for e50 across the board , etc. I'm sure there is a valid reason and I trust Halim@HCP and his reasons.

Just posting 1 to save some time. |

The variability in pump gas quality/octane is just another reason why I will basically never go back to pump gas over E85 mixing. |

Hey guys,
My tuning experience has been quite the journey to say the least lol. Went FBO and BM3 Stage 2 91 (CA) the same week my extended warranty expired. Everything seemed fine... until I went BM3 OTS E30 and basically my car had terrible timing and clutch slip. Here is my updated log with the Spec 2+ clutch upgrade, and NGK plugs gapped at .0023. I did this log on a whim. I don't even think I was keeping track of my RPM's correctly due to timing constraints lol. https://www.bootmod3.net/log?id=5fb8...90c64d73a0a4fd Mods: CTS Turbo Intake, ERW Charge Pipe, CTS Turbo Catless DP, Wagner EVO 2 Comp FMIC, AWE performance midpipe and axleback, NGK gapped plugs and SPEC Stage 2+ clutch upgrade. |

Quite a few timing corrections. What E% did you target? Did you measure ethanol content from the pump? At the time same, you are getting some dips in HPFP pressure so i dont think you can go any higher in ethanol content to help. Any more ethanol and you will probably crash the HPFP. |

Not sure if this is relevant, but I also have access to 100oct that I could work with.. Is CA's 91 that bad that a ~12 gal of 91 and 2.5-3.0 gal of E85 just isn't cutting it? Thanks for checking my log jeremy! |

As strange as it sounds, i actually tried adding ethanol (2-3 gal) and running the 91 map but still had timing corrections. When i switched to the E20 MHD S2+ map, which targets way more timing, i had fewer corrections. Of course, the E map runs lower boost, but not by much, and i was running more ethanol, but it just shows its a little tricky. If you are committed to running ethanol and really want to make power, i would suggest measuring the ethanol content, going for a E25 mix, and running the BM3 E30 OTS map. Log to check timing and HPFP. Read the "E30 fueling" thread for a good discussion and how to do that effectively. The other tricky thing about adding ethanol to a pump gas map is that the pump gas maps target higher boost than the E maps. So, you can actually add more ethanol to the E map because the boost target is lower. Your log was showing upwards of 18psi, which is more than the HPFP can handle with any significant amount of E. So, you might not be at your ethanol max if you were to go to the E map. 100 octane would be fine if you were going to use it for a track day or something, but you probably wouldnt want to pay for that with every tank. And yes, our fuel quality is terrible... I am in SoCal, and i used to run the 91 map. Once i went to the E20 map (MHD) and started mixing ethanol i never looked back. WAY more power and way more consistent timing. That's why the ACN maps exist in the first place, because our gas sucks. |

For kits, order this one: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 You want the large tubes, with etched markings, and you want two tubes so you can easily do E85 and pump gas in the same stop. When doing the testing, be as precise as possible adding in the water to water line and fuel to fuel line. The easiest thing to do is bring a disposable cup, dispense from the nozzle into the cup, then use the pipettes included to transfer exact amount of fuel from cup into the tube. |

I'm really going to have to measure it. because I want to stick with Ethanol mixes. The loss in power from going back to stage 2 would eat me up inside lol! So going by your last reply, it would appear that I need more ethanol? Bimmerbloke estimated I had around E23 which is undershooting significantly. I'm going to go by your method and try for E25. Man, all this talk of MHD makes me want to make the switch. The Fueling is becoming quite the hassle man. It feels like I have very little room for error. Reason I brought up 100oct was to compensate for our shit soCAL gas, i.e adding a gallon or 2. But I don't want to make 2 trips lol, and the price of 100 is insane. And yes, I was at the BM3 E30 OTS map in that last log. sorry for not being more descriptive in my initial post. So for clarification, more boost requires more E with these E maps. And if we base it off of the E85/E10 assumption, it's safe to say I'm undershooting. In the end there's no true way of knowing until I start testing the content. Back to the lab I go for more logs lol. I'm determined to get this right. |

Anyways, I just took another quick look through the log. Given that your IATs are over 100F, my main concern with upping E% would be HPFP crash when its cooler outside. Having said that, i think the best approach right now is to get the test kit, test the E%, run your tank very low, then do a target mix of 25% and log that. In the meantime its not necessarily dangerous to run this map or anything. You could also just run the tank low and switch back to a pump gas map, up to you. You could also assuming E10/E85 for pump gas and E85, target a E30 mix based on those concentrations, and log that to see if its too much for the pump to handle. Depends on how patient you are. |
