If I make a change in the PS vs Diff TPS should I also make an increase of some sort in the PS vs Diff MAP? Maybe an entry level question but I'm an enrty level kind of guy.

thanks,
Lars

 

Good question. I'm also curious to know what conditions and when it is proper to change the Pmp Shot VS diff MAP.

I'm also curious as to what part, if any, of a Carburator the PS vs Diff MAP emulates.

 

Nope, they are totally independent for when you use what. They are like the discharge nozzle size, but don't change the duration of the shot like nozzle sizes do.

On some cars a change of "1" makes a ton of difference, so go slow. When first tinkering I tried 3 one time. Made it about 4 blocks and had to put the old chip in.

BTW, ALLOWS carry your last chip with you just in case.

 

Thanks for the advice. I scaled both by 1.125. I gueess I'll be changing them back.

Thanks

I never make over a 10% change in anything unless I really really sure about what's going on.

 

Depending on the scale of a table, if the total of a table is 100, i usually change things in .4 or .8 increments, if the table is in percents i change it by 1-2, maybe 3-4 if its way off.

IE, tables in 100(VE tables), i did the .4-.8 changes

tables in percent(open loop clt vs. afr) i did the changes of 1-4percent.
