Probably a good thing. I'm toying with the idea of just letting Tailgate McNoIndicate sort this one. But I guess they will hit me with a massive bill.

Intercooler is not broken. There is a 2mm hole om the back of the intake manifold though.
Who decided to make those out of plastic?
Stupid idea.
Well, thats all about the daily.
I've run into a strange problem with the idle on the toyster. On petrol it happily idles at 950-970 rpm. On e85 it rather does it at 1050-1100. The idle settings are obviously the same regardless of fuel.
I suppose I will give it some time, re-check and redo/tune it.
All that is secondary when you drive it though. I really hope that I get the opportunity to get it on track before I put it in for the winter. Don't dare to book anything before its tuned on the dyno again.

And people that make the cars try and meet fuel efficiency standards (plastic is lighter, so less vehicle weight, so less fuel needed). But mainly accountants... |

It is a sad thing. Sometimes I get the feeling that most modern cars are made to last the warranty time and no more. Same as power tools really. and appliances. It is a sad state of things.

Oh, totally. I had an e30 and an e36 Tailgate McNoIndicate - if you look at the way those were built compared to the newer ones you can tell they were designed by engineers not accountants...

So, going through logs I found that the flex fuel sensor signal has random peaks and dips. Some research on the matter showed that this is a problem with the earlier ms3 firmwares (Im currently on the 1.3.4 from 2015). This is a bad thing when I plan to put down an e85 power map on the dyno in a few weeks, flashing firmwares is always pretty exciting. Not that I have done it on the ms3 before. Tunerstudios latest release have a convenient firmware loader, this is nice. Currently awaiting response from Dimitris (reverant) about if the mslabs ms3 basic uses some custom firmware. I know that some of his ecu's have done so in the past, but I don't think the ms3 basic does. In this case its best to be sure though. Hopefully, a firmware update screws up very little when going from 1.3.4 to 1.5.1, but I believe it may have changed the idle settings / algorithm. Oh, by the way, I took care of fixing my idle today. now it idles like stock, on 830rpm closed loop. I guess I'll have to redo that after the new firmware  Edit: 30 minutes later, reply by rev. MSlabs ms3 basic uses the standard firmware. Great  Now I need to get up early tomorrow. |

Yes! Firmware 1.5.1 up and running. Hopefully it cured my flex problem. Went without any problems. Had to fix idle again, but no changes that wasn't covered in the firmware release notes. Will redo the closed loop boost control when I have time to drive it. Also found a small water leak. Going to change a worm clamp to a oem typ clamp, then it should be cured  |

It cured my flex problem. Since boost control is re-made I'm running in setup mode until dyno day. I do need to keep a large delta in the closed loop activation, otherwise I overboost in between gears. .64 a/r is somewhat spooly. Sadly, this means I'm not seeing full spool on sweeps now. I may fix this and run true closed loop before the dyno, but we'll see. I need to focus on work for a bit.

A virual dyno of a run i made yesterday:  This is with sligtly less than 16psi and completely untuned ignition. Its probably a load less power than I will have with the same pressure on the dyno (when we actually tune for e85 ignition). The accuracy of VD is up for debate, but here it shows power in whp, and butt dyno agrees with the wd numbers. In second and third I actually have to tension my neck. The odd notch is some kind of artifact, the whole torque curve looks wonky at 6k and above. Oh, and the strangeness of the curves is probably a combination of bad/safe ignition and undulations in the road or something The slowly rising torque low down is due to my initial boost targets being lower för driveability. |

3rd gear run, same settings. I can't be bothered to make it smoother before the dyno. But those curves will be better.  |

Today was dyno day #2 with the new engine. This dyno is a bit of a heartbreaker, they say. I think it was about what I expected for a 9:1, forged, ewg bp4w with volvo valve springs and bp5a intake cam running e85 and 1.3bar boost. Am I happy? YES! This is a fast car now. Not quick, fast. It also started to command some respect. flooring it in the wet takes a good bit of planning, first and second gears are redundant in the dry, good for parking Nah, with less than 70% tps it runs on wg boost, this makes it ok to drive in any condition. The graph is power and torque to the wheels. What that equals to in flywheel power? I don't know, but the car makes me smile The petrol map is still 0.7 bars, 226whp although smoothed. The graph below is with >80% ethanol, any other mixture it interpolates between the maps.  |

you can legit call it a 400hp car now  400.08hp if you take the 20% seriously. nice lines from ... congrats! |

Thanks It's hellafun. I really like the 100/200/300whp rpm points it doesn't feel as dramatic as it looks on paper. As long as you are in fourth gear or above, heh. |

Woof! Need video on track now... Yup, need to drive this on track. Sadly, I'm not sure if I can, season is coming to an end here, I'm on call a lot during the weekends and the gf is very pregnant. Hopefully I'll find something |
