running too lean/ DATALOGS?

Post by garrett »

finally got it to start but now seem to be having a problem with it running lean. read the tuning section and din't really find anything. it ask for the map KPA in the table generators. This engine is not available in fuel injection so how would I know what those tables are suppose to be.

As well we tried to do a datalog, i can find it in my megasquirt file but canot open it. ???????

you can open the datalog in exel...if you want, then spend hours trying to work it out.
do you have a wideband controller hooked up...if so use megalog viewer

How did you generate the initial VE table? Under Basic Tables\VE Table 1\Tools\VE Specific there is a Generate Table tool that can be used to create a best guess initial VE table. If you used that and are lean across the board, you can adjust your injector rate lower under Fuel Set-up\Injector Control (to increase the required fuel), or, in the Basic Tables\VE Table 1 area you can adjust the required fuel directly to make the whole table richer.
