At a minimum, I'd switch to Map 0 and flash the actual MHD E30 tune to see if you feel an improvement over the JB4 ethanol map. That should answer some questions before you actually ditch it. |

Since I'm planning on buying a custom tune from Wedge, I hate to also pay for an MHD OTS map if I don't have to. |

can you translate the descriptions to english? I think I see engine speed and fuel pressure but not sure about the others or their units of measure.

-0.5 C ambient is going to make it difficult to do a 3rd gear pull. You'll need to wait till the temperature warms up a bit and try 4th gear? The only data point that looks useful is 6900 RPM and everything looks good for a Stage 2 93 octane map

Alright, update on the MHD/JB4 saga.
I yanked the JB4 and reflashed back to stock via MHD, then flashed to the stage 2 E30 OTS map. (side note, man the wifi adapter makes that a breeze. Wish I had known it was an option when I first purchased MHD because it's only like 10 bucks more than the K+DCAN cable from bimmergeeks. Here are the first 3 pulls at operating temp after the flash to the E30 map. Interested in your thoughts because my butt dyno didn't register much. Car felt like stock at 50% throttle from stoplight to stoplight when getting up to operating temp and WOT pulls weren't anything write home about. Do the MHD OTS maps learn/adapt over time? Do I need to do some additional pulls to see additional gains? https://datazap.me/u/tnilson/mhd-e30-pull-1-3rd https://datazap.me/u/tnilson/mhd-e30-pull-2-2nd https://datazap.me/u/tnilson/mhd-e30-pull-3-2nd Edit: Technically SC_B5X did reply to one of my earlier posts with a recommendation to purchase the wifi adapter instead and my dumbass didn't see it before I bought the cable. |

I also sent these to Ken at Wedge, he's going to do a custom tune once the Supra hpfp is installed. I'll share his comments with the group as well. Edit: No go on reset adaptations for the high pressure fuel system. Thinks for a minute then says: "Failed. Connected" Last edited by Supr3me; 12-12-2019 at 05:52 PM.. |

I know for sure, my V2.0 logs changed the boost curve. It targets 14ish psi until it peaks 14-15, and then target bumps up to 16. It still overshoots a bit sometimes, depending on how fast boost comes on. I think higher rpm pulls have more difficulty controlling boost. But again, I just don't understand how it can be so difficult to lock in an EWG's boost control. I never had these issues with other OEM/aftermarket boost controllers and normal wastegates. Quote:
How are you guys approaching it? Seems like a lot of boost and timing for a base map. Are you just slowly increasing the E to see how it responds? |
