This file was generated on 8/11/2009 at 9:59 PM It is a good idea to turn off 'Word Wrap' to view this file if your screen resolution is less than 1024 X 768 and your using notepad. Also, a fixed width font such as Courier New will make it a lot easier to read the table at the bottom of this report **The changes created by this program are only suggestions based upon the imported scan. ====== File information ===== The paths to the 2 scan files that were imported was: F:\My PCM Editing Files\Scans\8-11 AM.csv F:\My PCM Editing Files\Scans\8-11 PM.csv The MAF table was extracted from the binary file located at: F:\My PCM Editing Files\Binaries\7-7-09b TCC and AFR Spark Tweaks.bin The suggested MAF table has been generated and was saved to: F:\My PCM Editing Files\Exports\8-11 MAF Tweak.txt ====== Applied Filters ===== Fuel Trim Cell filtering was enabled. The following cells were used in the calculations: Fuel Trim Cell 0 Fuel Trim Cell 2 Fuel Trim Cell 3 Fuel Trim Cell 4 Only the Long Term Fuel Trim (LTFT) was used to calculate fuel trim RPM Filtering was used. The RPM was at least 700 RPM to be included in the calculations No MAF frequency filtering was used, all MAF ranges were included No TPS filtering was used Air/Fuel ratio filtering was used. The A/F ratio must have been between 14.6:1 and 14.8:1 for the data to have been used in these calculations The ECT Range used was from 70* to 100* * Advanced Fuel Cell Filtering was used The scan data in Fuel Cell 2 was filtered by TP ranges between 1% to 100% Only these rows were included in the calculations for this fuel cell. The Fuel Trim Modifier was set to 25% Variable Fuel Trim Adjustments were made based on LTFT for each MAF cell - VTA_Value = 7 The Hit Counter was set to 1. This means the fuel trims must not have been 0 for at least 1 frames within the specified range. For example, this keeps blips of +10 fuel trims from skewing the calculations. ====== Boost, TP %, and PE Information ===== RPM Cell: 1600 Average TPS: 17.75 High TPS: 18 Low TPS: 17 Average MAF: 5331.75 Average RPM: 1441.75 RPM Cell: 2000 Average TPS: 23.25 High TPS: 24 Low TPS: 21 Average MAF: 5957 Average RPM: 1938.5 RPM Cell: 2400 Average TPS: 25.5833 High TPS: 27 Low TPS: 24 Average MAF: 6327.708 Average RPM: 2456.125 RPM Cell: 2800 Average TPS: 26.125 High TPS: 28 Low TPS: 25 Average MAF: 6435.75 Average RPM: 2678.125 This is the AVERAGE TP % when the engine started making boost for each RPM cell in the PE_Enable_TPS table. This was figured by averaging the TP% in each row where the MAP kPa was between 97 & 102, the TP% was the same or higher than the previous scanned row, and the transmission was in 3rd gear. Also, there must have been at least 3 rows in each RPM cell before calculations would have been performed. These values are averages, check your scan data before making changes to PE_Enable_TPS. ====== Change Table Description ===== The following table explains the suggested changes. It contains: MAF cell - This corresponds to the cell in the MAF table Old MAF Value - the value from the imported MAF table Average FT - This is the average Fuel Trim calculated from the imported scan file Adjustment Amount - the adjustment amount to be applied to the current MAF Suggested Change - This is the calculated changes to be applied to the old MAF table Hits - This is the number of times a non-zero fuel trim was logged in this cell ====== How adjustments were calculated ===== The Adjustment Amount is calculated by figuring the average Fuel Trim for each cell in the MAF table, then applying it as a % to the MAF table value. Any blank spaces indicate no change was to be applied Either the fuel trim average was 0, a filter was applied, or the MAF cell affected was not in the scan ====== Possible problems in the MAF table ===== These are areas where the difference between 2 cells is greater than 15% or less than 2% The only cells that were checked were cells that matched the imported scan data. Because of the variations in MAF frequencies through out the table, this is something that should be manually adjusted if needed. The suspect MAF cell is shown in ( ) Note: This does not indicate a problem. These are simply areas that may need to be looked at a little closer. No problems detected MAF Cell | Old MAF Value | Average FT | Adjustment Amount | New MAF Value | Hits | Cell Variance | Adjustment Percent ===================================================================================================================================== Hertz 1500 2.296875 2.29688 0 0% 0% Hertz 1625 2.671875 2.67188 0 16.32653% 0% Hertz 1750 3.070313 3.07031 0 14.9123% 0% Hertz 1875 3.476563 3.47656 0 13.23155% 0% Hertz 2000 3.898438 3.89844 0 12.13483% 0% Hertz 2125 4.351563 4.35156 0 11.62324% 0% Hertz 2250 4.820313 4.82031 0 10.77199% 0% Hertz 2375 5.304688 5.30469 0 10.04862% 0% Hertz 2500 5.828125 5.82813 0 9.86744% 0% Hertz 2625 6.40625 6.40625 0 9.91957% 0% Hertz 2750 7.132813 7.13281 0 11.34147% 0% Hertz 2875 7.632813 -1.371429 -0.01046786 7.62235 7 6.8631% 10% Hertz 3000 8.382813 -1.519355 -0.01401012 8.36880 93 9.79302% 11% Hertz 3125 9.054688 -3.120035 -0.06215208 8.99254 3620 7.45307% 22% Hertz 3250 10.3125 -3.663789 -0.09445705 10.21804 1262 13.62806% 25% Hertz 3375 11.6875 -1.532585 -0.01970329 11.66780 178 14.18817% 11% Hertz 3500 13.03125 -1.887981 -0.03198357 12.99927 208 11.41149% 13% Hertz 3625 13.96094 -2.019524 -0.03947224 13.92147 379 7.09426% 14% Hertz 3750 15.4375 -2.028069 -0.04383164 15.39367 456 10.57504% 14% Hertz 3875 16.85938 -2.172678 -0.05494499 16.80444 604 9.1646% 15% Hertz 4000 18.24219 -2.242423 -0.06545074 18.17674 766 8.16631% 16% Hertz 4125 19.875 -2.148673 -0.06405733 19.81094 830 8.99064% 15% Hertz 4250 21.42969 -1.931985 -0.05796258 21.37173 719 7.87839% 14% Hertz 4375 23.05469 -1.831994 -0.05490686 22.99978 947 7.6178% 13% Hertz 4500 24.89844 -1.712013 -0.05115175 24.84729 849 8.03271% 12% Hertz 4625 26.85938 -1.995793 -0.07504806 26.78433 714 7.7958% 14% Hertz 4750 28.84375 -1.519879 -0.04822291 28.79553 674 7.50885% 11% Hertz 4875 30.9375 -1.632386 -0.05555213 30.88195 670 7.24565% 11% Hertz 5000 33.60156 -0.2361801 -0.001587204 33.59997 644 8.80133% 2% Hertz 5125 35.96875 0.1738184 0.000625203 35.96938 592 7.0518% 1% Hertz 5250 38.45313 -0.2116147 -0.0008137248 38.45232 353 6.90293% 1% Hertz 5375 41.03906 -0.1603351 -0.0006580001 41.03840 358 6.72544% 1% Hertz 5500 44.11719 -0.2364909 -0.002086663 44.11510 285 7.49713% 2% Hertz 5625 47.21875 0.2291093 0.00216365 47.22091 292 7.04024% 2% Hertz 5750 50.16406 -1.030974 -0.03620249 50.12786 226 6.15605% 7% Hertz 5875 53.78125 -0.4477841 -0.007224717 53.77402 203 7.27374% 3% Hertz 6000 57.57031 -0.5784994 -0.01332176 57.55699 200 7.03493% 4% Hertz 6125 60.82813 0.2120001 0.001289557 60.82942 125 5.68555% 1% Hertz 6250 64.71094 0.01111135 0 64.71094 81 6.38099% 0% Hertz 6375 69.32813 -0.5254903 -0.0145725 69.31356 102 7.11259% 4% Hertz 6500 75.45313 0.0842106 0.0006353954 75.45377 57 8.85859% 1% Hertz 6625 80.33594 0.07647081 0.0006143354 80.33656 68 6.47123% 1% Hertz 6750 85.09375 -0.3681819 -0.009398994 85.08435 22 5.90988% 3% Hertz 6875 89.5625 -1.95 -0.2445056 89.31799 12 4.97582% 14% Hertz 7000 94.39844 -2.61875 -0.4449706 93.95347 16 5.18986% 18% Hertz 7125 99.72656 -2.155555 -0.3224492 99.40411 9 5.80143% 15% Hertz 7250 105.3984 -1.028571 -0.07588685 105.32250 7 5.95388% 7% Hertz 7375 108.875 -1.04 -0.07926098 108.79570 20 3.29771% 7% Hertz 7500 114.8984 114.89840 0 5.60928% 0% Hertz 7625 121.3281 121.32810 0 5.59599% 0% Hertz 7750 128.0938 128.09380 0 5.57636% 0% Hertz 7875 134.5 134.50000 0 5.00118% 0% Hertz 8000 141.5313 141.53130 0 5.22773% 0% Hertz 8125 149.0859 149.08590 0 5.33777% 0% Hertz 8250 156 156.00000 0 4.63766% 0% Hertz 8375 163.9453 163.94530 0 5.09314% 0% Hertz 8500 170.5781 170.57810 0 4.04574% 0% Hertz 8625 178.0781 178.07810 0 4.39681% 0% Hertz 8750 185.5781 185.57810 0 4.21164% 0% Hertz 8875 196.625 196.62500 0 5.9527% 0% Hertz 9000 204.9609 204.96090 0 4.2395% 0% Hertz 9125 213.2891 213.28910 0 4.0633% 0% Hertz 9250 222.0156 222.01560 0 4.0914% 0% Hertz 9375 230.8047 230.80470 0 3.95878% 0% Hertz 9500 239.5781 239.57810 0 3.80122% 0% Hertz 9625 248.3438 248.34380 0 3.65881% 0% Hertz 9750 257.2422 257.24220 0 3.58309% 0% Hertz 9875 266.3828 266.38280 0 3.55332% 0% Hertz 10000 275.9219 275.92190 0 3.58097% 0% Hertz 10125 285.8828 285.88280 0 3.61005% 0% Hertz 10250 296.25 296.25000 0 3.62638% 0% Hertz 10375 306.9609 306.96090 0 3.6155% 0% Hertz 10500 317.9453 317.94530 0 3.57844% 0% Hertz 10625 329.2109 329.21090 0 3.54325% 0% Hertz 10750 340.7578 340.75780 0 3.50745% 0% Hertz 10875 352.5547 352.55470 0 3.46195% 0% Hertz 11000 364.5703 364.57030 0 3.40816% 0% Hertz 11125 376.75 376.75000 0 3.34083% 0% Hertz 11250 389.0469 389.04690 0 3.26394% 0% Hertz 11375 401.3828 401.38280 0 3.1708% 0% Hertz 11500 413.7578 413.75780 0 0% 0%
