can you please copy and paste you reply or link to the thread as I have a friend with a similar issue and we want clarification on caterpillar definition of static timing

 

3406e camshaft ??

 

the difference between the available arrangements of 2WS and 5EK

software, cam and injectors for different 550hp arrangements.

turbo on his unit is a 0000 650hp borg warner so that is up to the task.

if you want to PM it that's fine. hes only making 30psi boost (normally they go 38/40psi) with the 550hp file. even if he turns the 8501/23/57/2.82kg/min injectors up to flow that of a standard 8502/24/3.07kg/min its still gutless only putting 460hp to the ground and pyro doesn't go past 430 deg C

current cam 1361157
file 1708226

 

What the serial number of the engine and what is current flash file, cam p/n, injectors, etc. Guessing this was an overhaul that you uprated HP.

 

The current cam P/N for the one you listed is a 187-9381. It is used in 5EK upper HP settings with 58's/8502 injectors. The flash file you listed is for Pre-low NOx 1LW 550/1850 file that would use 57's/8501 inj and a 139-0537 cam. Only specs Cat gives on cam is actual lift and only difference is of two cams is 0.001 lift on injector lobe, but I bet shape and rise of injector ramp is different and duration and lobe separation angle could be different on intake and exhaust. If you have 58's/8502 in it, have you tried the 170-8132 5EK 550/1850 file. This way injectors, cam, and ecm flash match.
