when logging it is super important to be consistent. Also, this is why I really dislike tuning tip cars (kick down etc.) and i was hoping to keep this thread restricted to 6sp .... |

I have a TCU program I use that restricts downshifts when in tip mode. Makes it more akin to a 6 speed. Won't help here though. |

No we appreciate your help, but if the car isn't 100% mechanically good (and that boost leak is really killing you), then yea, it is kinda cluttering  |

To get this back on track: I don't think this is a HBN problem.. My thoughts: * 160 req load with very low IATs will have a pretty low boost req - we should consider maybe requesting more load * I don't think we should express LDRXN in boost, since the load->boost conversion is very IAT dependent (although we could counteract it in the spec load -> cor spec load path with KFTARX) * req boost isn't tapering because of IAT rising from stock ICs... that is pretty much canceling out the spec load taper |

Something is wrong. Likely a boost leak. |

I'm rockin a TIP with a mod from Daz, wish I got the kick-down turned off lol... makes the car more like a manual plus logs are hard to get like at 3000k or below, you gotta roll on it low part throttle and then do WOT like my logs show.
Gonna suck for dyno guy. O well he don't get it correct they should have to do another run to make up for it. My last car then stopped dyno at 6500. My turbo was pte6152e didn't make 20psi to 4500, and the cams where ready to go already hks272's but I had it tuned to 7500rpms. I felt I got lower reading on dyno and seen and felt more like 370awhp not 345awhp on a 4g63

My understanding of the requested boost table (LDRXN) is that it approximates what the requested boost will be, but is not a direct determinant. The boost curve that I log should roughly follow the shape of what is planned, but the magnitude of the boost value may not match what is in the table. What I'm finding odd about the resulting boost profile is how it climbs where the 'requested' values in the table are decreasing. That's the part where the other factors come into play, and illustrates how the table is not the sole driver of the resultant boost profile. Here's a chart with the new variables:  |

Yep. Nye and I spent quite some time talking about how to best approach this.
We decided to just try increasing LDRXN by an arbitrary amount and ditching the PSI conversion.
Care to give that a shot Jeff?

Sure, here's the revised profile.  Do you think timing is ok or should I try refining it some more? Care to explain what those extra variable I logged are telling us? |
