Select the Mixture Table tab on the top of the data log screen. Do autronid ground igniter at same point as SM4. Charge Temp Estimate This is the actual temperature of the air that goes into the engine after it has passed by the manifold and entered the combustion table. Read from external file Reads table only from a file you select. Operates any time TPS excides this value. It also implies that the fuel consumption will go up slightly, due to the extra work for the pistons to push the exhausts out of the cylinders.

Note pressure readings needs to be after butterfly Set “Base fuel delivery” y axis as Throttle. Autonic manifold sensor not connected to the manifold OR you have a seperate baro sensor, set “Baro update” to “Sensor” else use the “Baro press estimate”. The Autrobic of the table show Engine speed rpm and the Y-axis show Coolant temp.

If you use a low-pressure feeding pump to the high pressure pump, place a check valve after the low-pressure pump. Increase values to richen and decrease to lean. This calibration table may also be used to increase the idle speed if engine overheating occurs so that engine driven cooling fan efficiency is improved helping to elevate the condition. If you can not achieve the required fuel flow from one pump, you can employ two pumps in parallel.

Calibration for idle speed increase required of automatic idle speed control function during low temperature engine operation. Making changes before all fuel sites are tuned can cause confusing tuning problems.

This is used to tell the software whether the engine has been tuned before or if it is a brand new calibration. Mmanual overall warm up enrichment. Some of the starvation can be handles by TPS acceleration enrichment. This is one of the dedicated PWM output pins, and it provides a reliable PWM signal with selectable frequency ranging from 9. This is shown in the following illustration as an upward or downward facing arrow.

Some functions are only available from some menus. Press F8 to start the PC logger. But on a race engine we want this to be fuelled for best driveability without heat buildup, and without filling the engine up with sot. If there is no empty connector it can share with the fuel regulator or boost gauge. Anti Lag can now be configured under menu M5 — Anti Lag. Used to start and stop ECU data logger while online.

Tag item You can tag cells so that only those cells are edited via tagging functions. The additional timing at RPM will help the engine to smoothly return to idle. Then set all the cells in the table to zero. The sensor should be autonic after the engine and before the thermostat in the coolant circuit.


An upward arrow would indicate that the trigger edge is the transition from low-to-high and is called rising edge. Locate the ignition wires in your harness, using pins, crimp the pins onto the appropriate wires and insert them into appropriate locations in the igniters plug.

If want to zoom all items plotted on line 3 to a single line then can do it here.

The only true way of determining this is using an true Autronic analyser. Variable camshaft control setup. You can also select the fervency like the example above. Login or Sign Up Log in with. As a rule of thumb, it is said that the highest boost pressure will be found on third gear. The electrical connections to the two ends of the potentiometer fixed terminals must be chosen so that the output voltage increases with increasing throttle opening.

Open screen layouts Opens exiting screen layouts. If pot is turned fully clockwise then launch is completely disabled, and when turning the pot down, Launch will be available.

Record the engine RPM. See chapter Dwell for more information regarding how to fin out coil charge time. NOTE, When engine’s at running temperature, should have enrichment multiplier of 1.
