IP timing -1.94
 

I would sure like to learn more about this timing that member Crazy has in his sig



1997 3500 Ext Cab 2 Wheel Drive 300,000 plus miles
New Trans with up grades for towing Rebuild Rear end 4:11 with
new axles,newjectors, 4" Exhaust , 5" tip, PMD Moved to front
bumper,IP time to -1.94,new LP,boost,EGT and trans gauges and
pull a 38ft 5th wheel with 3 slide wgt 16,500lbs

it turning pump to the right for max power with out setting SEL off it retarding pump

I understand that part, its just different than a 12 valve cummins by a long ways

can you give us detail on how to get to the -1.94 and what all it takes

just have my buddy part on his tech2 scanner he did the timing he set all up for me lost 1/2 mpg though but get more power and great when towing i know cummins total diff from chevy could tell you if do anything for that pump on not

Correction not retarding

advances the timing basically tells the computer where the best spot to inject is better mileage, throttle response and make engine a bit louder but i didn't see better mileage
