Tuning '03 suburban with procharger, 1 bar
just a few questions.
1. truck has stock injectors, should I get lucas 42lb'ers or run stock and check duty cycle and afr
procharger kit is 7-9 lbs
truck has a rising rate FPR, has no KR, but is running lean
have not checked with wideband but narrowbands are only getting to 850
I have an LC-1 and will begin tuning next week
2. Is this the correct path for tuning?
a. injector flow rate(if not using stock injectors)
b. idle tune (if running cam with unstable idle)
c. autotune VE table
d. power enrichment tuning
e. MAF calibration (if still running maf)
3. when does the vehicle enter PE mode?
I looked at the parameters under mixture but it doesnt tell me when PE is operating.
4. should I upgrade to 2 bar map sensor and custom OS to run 7-9 lbs?
would this be easier to tune with?
5. after I reset LTFT's, how much driving is required to see the results?
are reccomended LTFT's different for a boosted vehicle?
TIA for any help
