hello

please help me with a few basics..just learning datalogit.

in Fc-edit you have INJ,INGT,IGNL,BASE MAP,and then the pages....are the numbers in the IGNL & T maps actuall timing #s or are they just reference points???

what are the numbers in INJ MAP (are they a percentage or what?)

what is the Base map and how do changes in the inj,ign maps affect it or does it work the other way around??

ok one more is there a way to change the tps voltage into a percentage

I have many more questions but thats enought for theis post

Thanks for any help

Start by reading the Datalogit docs on the installation CD or FC-Datalogit user group (must be a registered member)...

then read these...

Both. They are actual timing numbers in reference to a position of the eccentric shaft. IGN trailing split is different as it's the difference of the IGN trailing and leading.

Basically. The current cell in the base map is multiplied times the current cell in the INJ MAP and then other corrections are made in a similar way.

Ignition maps do not have anything to do with the fuel maps (base & inj maps). Nothing really affects the base map except the tuner. Everything else is a correction to the base map. The numbers in the base map are injector on times. The longer the "on" time the more fuel is injected.

It's not possible to change a voltage into a percentage. Two numbers are needed to come up with a percentage kind of like a ratio. The TPS voltage can be changed by a percentage but then the percentage must be known. Percentage equation...

N/D=R*100

The ratio is usually read as a percentage without showing the multiplying times 100.

Example...

9/10=.90 or 90%

9/10=.90*100=90%

Them was some tough questions the way they was asked. Please do some reading newb .
