Record the engine RPM. Setup camshaft tolerances under”M1,Variable cam setup” 3. And at degrees the boost pressure is reduced by 60 KPA to protect the engine. This table is the equalizer.

However the trigger will take control again when crossing the trigger threshold When logger full, will override oldest data in a circle buffer arrangement. Now we have configured the boost control.

This is achieved with a higher than normal idle speed to RPM typ. Also on turbocharged engines with wild camshafts and all sk4 engines where auyronic want to map the fuel delivery against throttle position and ignition against manifold pressure.


And that we got the wanted KPA at rpm. See wiring diagram fore more information. Useful when ECU is password protected or do not want a table opened to display live data. Unpack your ECU and identify the following components, some components may vary if ordered a specific kit.

Can be used to find the value between table sites. Set this up under “M2 tables axis setup”. Digital Flex-fuel sensor capable, using mankal single manuap input that accepts both fuel composition and fuel temperature. Single type Bosch 0 Triple type Bosch 0 and 0 When the coolant temperature climbs above degrees, the SM4 will start lowering the boost pressure to the values in the lower row, degreesto save the engine.

Used for different boost maps on different gears, Traction control and displaying selected gears in the log. Making changes before all fuel sites are fully tuned can cause confusing tuning problems. But for now we set it to all zeros. Smaller values can make for less drive line noise on deceleration.

This allows you to copy between tables from different screens. One signal consists of evenly manul pulses, each representation of 2 deg engine movement. Minimum IAC valve position allowed. Analog channels can use these tables. Since the pressure regulator operates on a return system, there should always be fuel being returned to the tank, even when fuel flow to the engine has reached its maximum.

The engine RPM above which over-run shutdown starts. The chamber in a WG that add boost with added pressure.


Large value Causes quick return to the base idle speed. Set engine RPM limits against engine temperature. Compatible with 2 and 3 wire and stepper type actuators.

This table, the engine “load”, barometric pressure and corrections dependent upon intake and coolant temperature, acceleration and deceleration and external trims determine the actual rate of fuel delivery for all engine operating conditions. For qutronic capacity 2 valve engines -2 to deg should suffice. Either a linear or rotary type potentiometer sensor may be used. The reasons for this can be that there manuual not enough fuel for a higher boost pressure at that engine speed, or that the engine simply cannot handle a higher boost pressure at that engine speed.


P-S Fast idle inc Post start fast idle increase.

This zone is where the engine is transient in and out of overrun. Eight arbitrarily positioned injection events per engine cycle are possible with any combination of the majual outputs firing at each event suits odd fire engines. If using a speed sensor and configure Launch under menu M5 Launch Control you will have a fully automated Launch control. Make sure only shielded wires are used if using inductive sensor. Then we log a test run at this lower boost, and modify the cells in the Boost offset table for KPA until we get exactly that boost pressure.

The values in the table represent wanted boost pressure in units of absolute KPA. NOTE, May be trimmed to read correct volts.

Values that are different with have a x before them.
