i recently purchased a turbo kit which contained a garrett gt28 turbo n internal wastegate set at about 5.5 psi, e.l mani, charge pipes, oil lines water lines, bov, intercooler, 2.5 down pipe, generic air filter, map management unit( black box ) , 2 additional injectors which come installed in a 3 inch tbody spacer n a fuel management unit. this has been installed in a 2001 civic non vtec 1.5 ( d15y3 ). due to tax n the duty structure in this country the non vtecs are a 1.5 n the vtecs are 1.6. with the kit i got a 10 page manual which had the installation details n the last page had instructions for the fmu n this is how its printed; 1. MAX P +0.53kg R=5900 2. RPM PRESET =8500 3. DEL TIME =060 S ( TURBO TIMER ) 4. BOOST IJ p=0.0kg , t=1.8ms p=0.1kg , t=2.8ms p=0.2kg , t=3.2ms p=0.3kg , t=5ms p=0.4kg , t=6.6ms p=0.5kg , t=8ms p=0.6kg , t=10ms p=0.7kg , t=13ms p=0.8kg , t=14ms p=0.9kg , t=15ms p=1.0kg , t=17ms p=1.1kg , t=19ms p=1.2kg , t=21ms p=1.3kg , t=23ms p=1.4kg , t=24ms p=1.5kg , t=25ms p=1.6kg , t=26ms p=1.7kg , t=27ms p=1.8kg , t=28ms p=1.9kg , t=29ms p=2.0kg , t=30ms 5. RPM IJ rpm=1500 , t=0ms rpm=2000 , t=0ms rpm=2500 , t=0ms rpm=3000 , t=0ms rpm=3500 , t=0ms rpm=4000 , t=0ms rpm= 4500 , t=0ms rpm= 5000 , t=0ms rpm= 5500 , t=0ms rpm= 6000 , t=0ms rpm= 6500 , t=0ms rpm= 7000 , t=0ms rpm= 7500 , t=0ms rpm= 8000 , t=0ms 6. ADJUST RATE =68% 7. PRE LIMIT =0.8KG 8. ACYC=17 , T=1.8MS now if i insert these numbers in the fmu the car just sputters at 4000 rpms n doesnt go beyond that. if i increase the time, t , at every boost point n the time, t , at every rpm increment then the car gets better. i havent changed the adjust rate n the ACYC since i have no idea what they mean. the boost time n rpm time can be increased by 0.2 ms till 51 ms being the highest point. what i dont understand is that sometimes the car performs better at part throttle than wot. what is the correct way to tune with such functions, now i know that having the car dynod is the best way to tune a car but since we have no dynos in this country i am left with no other option but to ask ull. forgive me for this awfully long post but i thought it was best that i explain the whole scenario. any feed back will be much appreciated. thanx in advance. btw this kit was bought from a supplier in thailand.
