Once you have your tune loaded and turn the key on you will hear the fuel pump prime and shut off. IF THE FUEL PUMP DOES NOT SHUT OFF THEN THE TUNE IS CORRUPT, DO NOT TRY TO START THE ENGINE. Then set the base fuel pressure to either what we discussed (typically 55psi if you have less than 60lb injectors). Next verify the ignition timing is at 10 degrees btdc with the spout plug removed. This is VERY IMPORTANT otherwise you risk damaging the engine. | |
For EEC-Vs that have been converted from returnless to return style, the fuel pump may run constantly with the key on unless I have written
custom code and remapped an unused output pin to control the fuel pump correctly.

Base Fuel Table | I null ==1.000 so interpolated lambses don't skew my corrections |
WOT Multiplier | assign all 1500+ rpm to wot lambda (just in case someone goes WOT its not commanding lean) |
FN320A | I max it out so open loop is forced only by tprel while i dial it in since fn035 won't be dialed in yet |
WOT Breakpoint | I kick it up along with the OL breakpoint scalar so i can see how the fuel trims up top |
Hego Min Switches | I set it to 1 switch so it goes into closed loop quickly |
BYPLES | I kick it up to 60 sec for initial tuning so the hegos have 60 sec to fail if the fuel is too far out and it can't switch in a shorter period of time |
