Gen 3 5.3L ON3 turbo, my first turbo tune, any help
#1
im working on a XJ cherokee, with a 5.3L/4L60 .. this is my first turbo tune so any help will be great, its my own truck
-Engine is completely stock
-Transmission is a 4L60E i got it from monster transmission
-turbo is a On3 76mm turbo
-3Bar map sensor ( im runing this one because i already have it and maybe will add more boost later)
Fuel system:
-Stock return type fuel rails
-Ford lightning green injectors
-Walbro 255 intank fuel pump
PLANING TO RUN 8-10 PSI of boost
As this car will be used as offroad, i want it to keep it simpler so i want to run it in custom OS Speed density, in Open Loop, ( No o2s sensors)
Im working on a 2003 truck tune as a BASE..
changued the C6301 to 283.5 , Key on engine off shows 101, it has to show that right?
The other question is about the injectors; i look for the flow rates, on a ford forum they say they are: the lime-green ford lightning(ford motorsport) SVT M112 are 440cc@3.0bar , using this info and the injectors.xls, it shows me : 6.2987 , is that a correct flow rate for this injectors?
-----------------------------------------------------------------------------
i found that the injectors flow rate at 58 PSI is: 6.1108
MY MAP looks to be measuring right
does my starting base tune looks sane??
ill be using LM1 wideband, will work on both VE tables. i will start playing with timing then.. does this looks ok? or im totally lost?
------------------------------------------------------------------------------
started the truck, it looks to be working right, idles normal, i changued the values on B3647 and B3649, think im going to control fuel with Power Enrichment..
