attention motor heads

is it possible to add resistance to TRS signal to alter timing on series-60 Looking to advance timing without laptop on 2004 epa 515hp egr engine from lousy 13 degree btc to the normal ( pre- egr) 15 degree. any help would be welcome

 

i have tried a potimeter on the ait sensor and that kinda worked. was just comparing data specs on valve covers between my ddec-v and ddec-4 motors are trucks have and was thinking of ways to get a little more out of the egr model with less timing to have a little more grunt like the older ones.

 

the 13 degree is factory timing on ddec-5 motor . 15 degree is factory on ddec-4 without egr. overhead has been done along with quarterly cleaning of all egr components including flushing cooler.

 

i've tried this and i have the resistor trick with pin connectors from radio shack to swap out with barametric sensor in case any egr problems occur on the road. Personally think for me not really noticeable for any power gains. turbo is more responsive off the line but that seems to be more with vnt being more active to compensate for thin air at higher altitude. Read somewhere in detroit literature that anything above mile high ,you lose about 2-3 percent horsepower.

 

thanks for the reply was just trying to look outside the box and alter what the computer see's. maybe santa will bring me a laptop with hardware and i can see what the computer is seeing lol

 

i'll have to look tomorrow. Could also see how much plastic is around the "eye" of sensor and shave down one side to give offset maybe
