Another: help analyze my logs thread (UTEC)
So I’ve just finished dialing in a new setup and could use some opinions with my UTEC log results. It’s taken several weeks to get the tune, standalone boost control, and waste-gate settings all dialed in, and I’m finally virtually knock free with a stable configuration of both Pump and Alcohol injection MAP’s:

one possible issue with turning up the wick... what's your MAP scaling look like?
from the logs it seems you transition into 100% column @ 17psi or so. you might want to make that right on the line of the max boost you want to run so that it functions more like an overboost column. i've looked at so many lines of log with wideband info. it's a bit scary to look at them without it! it sure would be nice to have some idea of your afrs. |

Yes I agree… Fortunately it was tuned with W/B including the Alky MAP. With the juice on it seems to be running a very safe margin with EGT’s below 1400 and absolutely no knock under full pulls. The pump map on the other hand is pushing it pretty hard at 19psi (1450-1500 EGT) and suffers from the occasional knock. Fortunately I have step down maps consisting of -1 timing and +1 fuel per step, for when I’m experiencing some heavy knock I can cut the pump tune back a little.

Looking at you maf voltage from both runs you can see that after 5700rpm the extra boost is not realy helping. For the alky map you should try more boost in the midrange dropping to 17psi from 5700 -7000 and run more timing up top.
This should be done after you get a wideband. |

Wow, you're removing a LOT of fuel. What did you scale the injectors to? What ECU are you running. With negative correction the whole way (and that large) I'd think you underscaled them.
The reason mention it is I'm running the same fuel setup as you with V39 and WRX ECU and run a max of -3.X to achieve 11.0:1, but you're at -15 in places! You're pushing some good air |

What were your AFRs tuned too?

are you saying you're pulling 4.6 mafv with a bigmaf and a ported vf22?

Is it a vf22 or has it been converted to an 1820? I've seen gt30's pulling that much voltage with the big maf @23 psi.

FWIW it doesn't matter if you scale them low and remove more from the map or vice-versa. I don't have my modded stockers scaled at all.

Edit! actually here is my RPM/MRP/MAF values from a run today. IAT was 12 to 13, 4th gear pull on flat ground. AFRs in the mid 10s which is also why I'm curious as to what his AFRs are. Code:
4535 -4.1 3.6 4535 -4.1 4 4604 1.9 4.2 4623 10.2 4.1 4701 15.9 4.1 4741 19.6 4.1 4782 21.2 4.1 4796 21.4 4.1 4930 21.2 4.2 5274 21.2 4.2 5005 21.8 4.2 5035 21.4 4.2 5104 22.1 4.2 5136 22.9 4.2 5151 21.8 4.3 5257 21.8 4.3 5299 21.2 4.3 5324 20.8 4.3 5411 20.2 4.3 5411 20.2 4.3 5464 20 4.3 5509 20.4 4.3 5518 19.4 4.3 5688 19.6 4.3 5678 20 4.3 5640 19.6 4.3 5717 19.8 4.3 5787 20.6 4.3 6172 19.8 4.3 5899 19 4.4 5995 19.4 4.4 6038 19 4.4 6093 19.2 4.4 6093 19.2 4.4 6105 19.8 4.4 6116 19.6 4.3 6161 19.2 4.4 6161 19.8 4.3 6301 19.4 4.4 6277 19 4.3 6253 20.2 4.4 6349 20.2 4.3 6410 20.8 4.4 6435 20.4 4.4 6497 19.6 4.4 6523 18.6 4.4 6574 18.6 4.4 6535 19.4 4.3 6693 19.2 4.4 6653 19.4 4.3 6693 19.4 4.3 6844 19 4.4 Last edited by cdvma; 11-17-2005 at 08:32 PM. |

Seriously though, TXS did the tune and I didn’t get a chance to witness the AFR’s under full pull on the dyno, for pump or Alky... The first thing noticed at the beginning of the tune was that the MAF was pulling voltage at idle which resulted in more fuel and rich conditions. It was assumed this was due to the higher flow from my filter, intake, and tube setup. I believe that rather then significantly cutting the fuel map up, the guys simply reduced the scaling on the injectors from 820 (pressure tested) to 550, then worked the fuel map from there. It was a difficult tune to begin with as I had a damn IC hose which kept popping off the pressure side of the turbo. This didn’t affect the pump map(s) much as it seemed to hold up to about 19psi, but under the alky it was leaking and popping off every couple of pulls. I replaced the hose the next day and had to completely retune my AVC-R as a result. It appears the IC host was bleeding throughout the entire tune anyway as the beast came alive after the new hose and reconfigured AVC-R. Put down 286ft-lb/309whp on the juice at 20psi with the boost leak. I’m guessing I got another 20whp (330'ish) after fixing the boost leak and reconfiguring the AVC-R at 22psi. Thanks all for the comments Man I need to get a W/B |

Cool. I put down 275whp on XXs dyna pack in the dead heat of summer but I'm not catless...are you? I know its not a huge VF22 number but I was happy with it. I never wanted it bleeding edge. What mix of alky are you running?

^^^^ 50% distilled water and 50% denatured alcohol (ethanol). I run a custom built catless exhaust. Custom cuz it’s a motor swap setup installed in this:

so are you getting 4.6mafv with a bigmaf and vf22?
if that was while it was leaking boost, then sure... but that's an awful lot of air otherwise. |

After investigating a little further, it appears the intake I’m using is the regular Perrin short-ram, not the Big-Maf version. Sorry for the misinformation… I bought the intake setup used and replaced the foam element with a paper K&N after loosing my first MAF from it. This intake setup is combined with a Perrin intake tube (regular, not 3” big-tube version). During the last tune it was “assumed” the intake was in-fact the Big-Maf due to the MAF voltage issue at idle. After looking at it up close, it’s clearly a strait MAF tube not the beveled tube like the Big-Maf. These logs were taken post boost fix. Really the 4.6 is only a blip in each sets of logs, the constant maf value is a solid 4.5… From the quick conversion calc, that equals 4.5=339hp |

that makes a LOT more sense.
nonetheless, 4.5/4.6 is not too shabby with a VFxx. |
