Title: S4 M-Box: E85 - Franken Turbo- ID 1000cc - 4-bar - 044 - 95MM MAF Post by: vdubnation on February 14, 2013, 03:10:59 PM So I m new to this tuning world and have been reading my brains out
Thanks Daz i m starting to understand it a little more every day he know his s*it So we started off with a tune someone sent me and after looking at with Daz it was all wrong out with the trash and in with the nefmoto stage 3 Daz came up with a figure for Krkte for e85 and helped out with the crank fueling and the next morning it purrrrred off the wall it idled without any issues Some of the changes we made so far krkte = .04829 temin = .171 kfzw kfzw2 KSTT KFFWL kffwl_0_a kffwl_1_a We tried a maf table and every time i hit boost i buck like a wild horse but when maf unplugged it doesn't i got a code for the following 16486 - Mass Air Flow Sensor (G70): Signal too Low P0102 - 35-00 - - So as of now gonna take out my maf and drop the stock one in so we can dial in the injectors get everything 100% The car is going to be a track car super aggressive . Current Mods: 01 B5 S4 Fully Built Bottom End 2.8 Head Built Stainless Steel Braided Fuel Lines 044 Bosch Fuel Pump 95 MM Maf Bosch MAF 280 218 067 4 Bar FPR 3inch down pipe to exhaust injector dynamics 1000cc custom fmic waste gate 12psi manual boost controller franken turbos Bought the car from an auction with no tune with all the mods above except for the fuel pump . One of my old friends from high school has the same exact setup except for a the 2.8 head and his "pro tuner" he paid isnt getting him anywhere is having so many issues where the car hesitates on WOT. Looked over his BIN and its f*cked up. Looking for some insight please ! ALSO WANNA THANK DAZ !!!!

Your engine will not last long at all if AFRs are >14 @WOT. Definitely sounds like a hardware issue.
