Cold start M5 E60 mss65 160e for e85 fuel

[MtoufP]

Hi guys I have an m5v10, I installed 440cc injectors and a fuel pump to run on e85, my car starts badly when cold, please do you know where the engine cold start table is Fuel / ECT, I just have that as a problem, for the rest it runs well, but it's just at cold, it's a disaster

You probably need the injector flow constant and latency times to be changed. I'll have to check these, as I don't know them by head.

You need to have it tuned. Hit up HTE, he tunes E60 M5s.

KL_TI_SOLL_QSTAT_F = injector constant (mg/ms)
KF_TI_SOL_UB_OFFS = battery and fuel pressure depended latency times
K_TI_PHI_ENDE_ROH_KST = Fuel density (normally 0.75 kg/dm3)
Change these to your injector and ethanol characteristics

@ 5 bar fuel pressure and 13V
0.63ms latency
4.2mg/msec fuel flow
4.2mg/ms equals 336cc/min @ fuel density of 0.750kg/dm3
