In Latvia we have extended network of LPG filling stations, im thinking towards building liquid LPG injection for same reason - lowering intake temp and reduce knock risk. Company called AP Chemicals. Pure ethanol.. not e85 :) 10 hours ago, Simply Volvo said: Post up your ignition map. How are you monitoring knock? I don't have my ignition map at the moment, as i'm at work, but i have knock gauge which i have also connected to ecu, so when it hears something it retards ignition automatically :) Link to comment Share on other sites More sharing options...
Vykis199009 Posted August 4, 2019 Report Share Posted August 4, 2019 try more ignition with such boost on e85. i gained 30hp just by going from 19-20 to 23-24 at 1.5bar. now runing 20 at 1.8, all fine. I even think past 6k rpm, whiteblocks should need even more timing, at least looking to stock m4.4 maps. Link to comment Share on other sites More sharing options...

When i was tuning the ms3 pro knock system for my whiteblock I noticed the bosch wideband knock sensors are suppeerr sensitive and pick up a crap ton of engine noise. Im using the second resonant frequency and only 1/4 gain. Filters out all of the engine noise but still picks up real knock very easily. Link to comment Share on other sites More sharing options...
Mooseworks Posted August 12, 2019 Author Report Share Posted August 12, 2019 I can't try more ignition at the moment cause my injectors are fully used and while more ignition might get some more power.. it wants to have more fuel also so that just won't happen 😄 Anyway, another raceday behind us and time to write a little rundown😎 Since the last race, my bmw has "new" gearbox, which sadly is worn enough to not go into third gear when trying to change it fast.. but still better than the old one because that one wouldn't go into any gear. 😅 Also went back to the hx50 turbo i had from the beginning and new tune for it also. As i got a chance to do few pulls on the dyno, i used the opportunity and the results were quite what i expected according to my hunch - 473hp and 519nm at the wheels with 23psi of boost. All that was left, was to go to the track and drive fast. So did we? Welll... no. The track was very slippery, and i still don't know how to change gears.. pushing into third goes straight to a wall so yeah.. so no personal best for me.😁 But i managed to run 12.8@197kph with reaction time of 0.0012, so it is my best speed and also best reaction time i have ever done.🥳 But the car is fine and running good, so i'd call it great success. Next weekend, in Haapsalu, will take place One mile challenge 2019 by Audiclub, so lets see what the beemer is capable of. After that, I will try to fix the gearbox problem. 😄 I'll keep you posted. http://www.youtube.com/watch?v=vjGf-c0WcZc Link to comment Share on other sites More sharing options...
