Inliners International Forums General Discussion Hi Performance Help needed to change 4 piles into 1

Tom,

Warm the engine on the stock ECM
disconnect the set timing connector and using your timing light adjust the distributor so its running around 20* BTDC base timing. Leave the set timing connector disconnected until you have the idle/low speed fuel set up.

Plug in the MS

Crank and see if you are getting fuel sprayed, if not check on the laptop if you are getting RPM displayed. No RPM means no tach signal ->> no tach signal means no fuel sprayed. The tach signal is what triggers the whole meal deal. If you don't have a tach signal you have something mis-configured and you MUST fix it - nothing will work until you do. Also the fuel pump will not turn on past the inital 2 second prime period unless you have a tach signal.

- you may need to open the throttle a bit while cranking - it may take some diddling to find the right throttle position where it will start and run the first time. The amount of fuel injected during cranking is controlled by the cranking fuel pulse width ONLY not by the fuel table.
- once it starts, if its lean you may have to keep stabing the trottle to activate the "accel" pump.
- if its rich generally the engine will run but you will know if its burning your eyes out...
- as soon as it keeps running say at 1200 RPM open the 3D VE MAP (fuel table) and move the red dot using the arrow keys to where the engine is running indicated by the blue dot. And then either richen or lean the fuel until it idles - remember to adjust all 4 corners around the operating point.
Then let off the throttle a bit and adjust the next operting position. Repeat this process until your at curb idle and the engine will idle normally.


the Q key richens the fuel the W key leans the fuel

Also remember that if it floods open the throttle past 70% and crank - if the throttle is open more than 70% your in clear flood mode. Almost no fuel is injected. As soon as it catches let off or it will die from no fuel.
