    When scaling injectors or ve, do you make all ve and fuel multipliers 1?

    Ve multipliers like iat,ect and fuel mass multipliers like fuel rail temp ext? does this not skew the scaling for injectors and ve?

    When dialing fuel you want a constant ie injector characteristics. Get your flow data for your injectors and plug that in from there you will dial your VE tables. Do NOT set your VE tables to 1 the engine won't run... you do want to get rid of any fuel adders that will be in play. You want it to run on VE tables only, so turn off PE and use your narrowbands to dial your VE tables until your LTFT's are around 1-3% then worry about PE and WOT.

    Make sure your narrowbands are OEM Mopar sensors anything else skews their readings, also no plug in wire extenders, if they need to be extended you must solder them.

    yeah but his question is about 44279 44280 44281 44282

    i think?

    i always tripped on this table:

    44281

    why does it have the little extra down low and 1.4 above 4200???

    All four of those tables are VE modifiers. If you want to dial fuel right I set all those to 1 and then after both VE tables are dialed I revert those back and make small changes where necessary. For the most part are just failsafes to protect the engine in high IAT conditions and compensate for actual VE with low ECT after cold start
