couple of ?'s for new install

[supervert]

so i got megajolt lt. all hooked up today on my 63 ford galaxie with a fe 352. right now i am using the map download from the 440 mopar. everything is working but i have a few issues.

1- i cant seem to figure out the gm temp sensor values to input. and will it read in deg. when done? or in the 0-255 value?

2- the rpm/load is reading the right rpm, but the tach on the screen below shows the rpms double of what they should be. so at idle i have 800 rpm's in the rpm/load box and 1600rpm in the tach below.

i may be over looking all of this, it has been a long day.

thanks, jeff
