The prime pulse "squirts" when the very first primary trigger signals will appear, not after the device powerup.
That allows the fuel pump build the pressure.

Ok, thanks for your advises

Hi guys, I have a doubt.

When my map hose is connected, I have misfire about 2000rpm (neutral acc), but when disconnect map hose (always read 100kpa) runs fine. Can to be tune the reason? I think that when map its connected any time run lean.

Hi, fix your fuel cut
in Fueling -> fuel cut
set
fuel cut under pressure = 0
fuel resume below rpm =10000
fuel cut above rpm =11000

after tuning the engine go back and setup the fuel cut properly

Emu dont allow this settings. In Any case think that the problem its related with map. When map hose isnt connected, engine run perfect, but when connect this hose, tps like on/off switch and there is explosions and fire by 8 throttle bodies. Lightly loaded (20%) map readings quickly reach 100kpa.

What can to be the reason. I"ll try tune without map.

try to run this engine with ALPHA-N instead of speed density

[SUKHOI]

try anything above the limit that you can reach n normal driving check you log for fuel cut
do you run ITBs! if yes, what is your vacuum source?

Edit: added attachment

In Alpha-N run good.

I take vacuum to map from jack under individual throttle bodies.

Hi guys,

Could someone tell me correct knock sensor calibration? Its stock BMW sensor. 4.0 V8 Engine
Are ok my actual settings? I haven't idea to set engnine noise.


Thanks

[RHD]

on m50 bmw the gain needs to be about 0.7 and you will have to play with the frequency.

open log traces for both the knock sensor value and knock engine noise, set the noise so that when you free rev the engine up to redline the engine noise trace stays well above the sensor signal trace all the times, it increases as the rpm rises.

[pepifebles]

Ok thanks. We were mapping and did't saw knock sensor action or value.

Hi, I'm having issues with my iat sensor location. If I have intake throttle body, (v8 engine), where can plug iat sensor? Any idea?

[RHD]

any part of the intake ducting or aurbox seems to work ok
