Alpha-n or speed density ??
Posted: Mon Apr 16, 2012 1:36 pm
Hi everybody,
I have some issue, i have been running my bike for a year with a good tuned Alpha-n ve table and ignition table. Now i have added turbo and what i can read in manual i should change to speed density, should i use my old tables or should i make new ones from start?
Tryed to use the ones that Tunerstudio generates from start but the bike hardly start when use them. When i start the fuel load on idle is about 70 % then it stops direct, when i use fixed advance i can start the bike.
Would be wery wery nice if somebody could help me out to understand or if i have some setup problem and point me in right direction and/or if somebody have a base tune to start with
Thanks /Jonny
Some data for my bike
Honda 800cc RC46 engine Vfour 90 degres 180 degres cranc MS3 with MSX 1,1 beta, 255 cc injectors, Garret turbo, -0.2 Bar at idle, full bost right now is 0,5 bar, max Vacuum is -0.6 bar when i go from WOT to close, 15degres ignition at 1200 rpm and about 38 degres at 10 000 rpm(without turbo) Max rpm 12000 , 200 HP crancHP is goal. I have connect all 4 inlet vacuum house(4 mm) to a vacuum collection box with size of 1/5 of liter to ensure there is a stable vacuum for the MS3,
