I don't get it .............. ME is already available and proven (although it's not perfect) . Why wait for something that is in development and unproven.

derp. missed this comment. not sure if this was also directed towards me, but I have only stuck by VT because I have put a solid amount of effort into helping them bring the software to this platform that I would be an ass to just bail after all their efforts. I also like their interface, but that's the developer in me lol.

Us S2 guys can use all the options we can get lol. Just putting forth my efforts ;)

Hmm, so I'm starting to suspect that at anything over about 3V from the MAF sensor, or 100g/s the ECU is NOT using the MAF table to calculate fuel. At least, not the MAF table we have access to...

Changes to the maf table definitely do have an effect . what exactly are you doing and trying to achieve ? |

Have not checked this but , I don't think you can even be in closed loop at 100g/s ?????

I'm basically just trying to dial in the MAF calibration before messing with open loop fueling tables. For now, I've decided to just scale everything above 100g/s by a fixed amount, set the open loop AFR to 12.67 in all tables/cells and go see what happens. The car is a stock series 2 (stock intake) with a mid-pipe fitted for track weekends. Ultimately I want to end up with a tune for the track (w/ mid-pipe) and a tune for the street that optimizes AFR while keeping the cat safe. |

In 2nd gear my car switches to open loop at around 150g/s. I don't have many closed loop samples from my logs over 100g/s though, so it may be that my results are being affected by latency of the readings or throttle tip in/out.

Some of the things you guys are doing with the maf table really make me scratch my head . I've tuned multiple rx8s and it's rare that I even touch the maf table . Only when LTFT is out of whack and I know it is unlikely that some fault is causing it. I guess there are several ways to achieve the same result - the way you are doing it is the hard way . IMHO |

150g/s before it goes into OL ? Wow ! I can't imagine how you are doing that .

interesting. I will see if mine does the same thing.
|
Any updates Paimon?
|
Nothing :(, starting to give up hope. I sent an email at the end of last week for an update... no response yet.

Attachment 224946 There is a type in the notes - these were 4th gear pulls. |

Same with ME i suppose. But he is a bit abstract in his response especially when he says "hardware". So i wonder if that means if we brick the ECU we have to mail it to them to unbrick.

I'm aware of a couple flat out hard crashes with ME during flash that were all recoverable by restarting the flash.
One of which involved a lightning strike, fried hard drive, and power outage. |
must be something about the S2 ecu. not sure.
|
The lightning strike catastrophic power loss recovery happened with an S2...
|
oh interesting. Then i have no idea wtf VT is doing lol

Maybe it's because of the open port folks have been able to recover.
With my luck I'll be the guy that fries his ECU. |

Any idea how much the midpipe is adding by itself?
I will try and get a dyno run at some point, but making a back to back comparison is unlikely to happen. I do have an earlier dyno, but that is also before changing coils. btw, your dyno looks very smooth and healthy - good to see, mine was not like that at the top end. |
