hi guys...moderators..
i'm Jai (aka Jai Bluebird)..i'm a professional/expert category drifter..have been entering drift competitions seriously since year 2007...can view my drift car spec in my website
Jaimarketplace
my car..powered by Silvia S14 sr20det engine...estimated around 370rwhp at 1.5bar of boost. mainly, all mods to my car concentrates on engine response..suitable for small drift tracks in Malaysia..i've no dyno chart..no NAFSU to dyno my car because dyno chart won't give me anything..actual result in drifting and in drift competition that i enter tells me everything
i'm not a PS guru..i'm just a user..i've tried SAFC neo, SITC, HKS evc 5, PS spark energizer, PS boost controller, Power FC
my humble & constructive comparison..
SAFC vs PS fuel enhancer = quite same function, tricks the main ECU..both can't adj ignition, i presume both can alter ecu physical output signal in order to increase or reduce fuel by 50% max value. But....PS fuel enhancer too expensive..i really don't know why. Last time my engine blown big time while using safc..i ditch it and go for PFC. vs emanage..(i'll get myself an emanage anyday..)..emanage = superb cheap piggyback..yielded good results with my friends cars.totally worth every penny.
HKS EVC 5 vs PS Boost controller = i used HKS evc 5 for 1year..it hv many functions..really2 love the offset function (its called gain if u use Blitz dual SBC & greddy profec B spec 2, duty something i don't remember if use Apexi avcr)...if i set offset to 200% in hks evc..the wastegate will not open until it reach my preset boost level..super responsive and i like the punch when the wastegate opens at slightly close to 1.5bar. Recently, sold my hks evc, install ps boost controller (because it is highly recommended by my engine builder & tuner...i follow his decision because i trust him 110% with my engine that never failed me in competitions so far..helped my get 3rd place in recent MICCOS drift challenge..). My findings with PS Boost controller..
-at 1st, i find the level of easiness to set it is quite illogical..if comparing with the sophisticated hks evc 5. no need to run 3rd gear WOT to get the boost right..just dial in the potentiometer & wala..off i go..somehow..boost very stable at every gear (i'm boosting at 1.5bar)..response is much better than HKS evc..my assumption:
1. i think the solenoid design and the PID tuning for the solenoid control is superb..the solenoid response is very fast, my 38mm tial wastegate becomes restrictive..sold it..now using bigger one..solved problem.
2. at MARDI, serdang drift track, previously with EVC5..my entry speed is 110km/h... (starting from the same start line,same dry condition,same tire size/treadwear and i initiate drift at the same exact spot)..with PS boost controller..my entry speed increased to 130km/h. zyful can confirm this,he was there during this drift practice.
My comments:
-i love the PS boost controller..from my actual experience..excellent!! try it..u will know what i mean.
-my engine builder/tuner recommends PS boost controller & spark energizer. i also recommend these two..because it have significant function..to control boost accurately while increasing response/stability n etc...and to ensure optimum spark energy at WOT.
-for PS fuel enhancer & other PS products..my honest opinion as a consumer..too expensive,better get used safc..bang for the buck..n get quite similar gain
-or....there's no replacement for a standalone ecu..i'm using a PFC..really love it..gives me the gain and result that i wanted. never failed me...
last but not least..for standalone ECUs...a tip that i always give to my friend... "An ECU..is just as good as the tuner..always select the tuner that you are comfortable with based on your own research/study...and select the ECU that he is capable and competent in tuning for your engine calibration purposes...in Malaysia, there's a very high tendency that it might not work as per your expectation if u do it the other way around"
Khalas...my 40cents opinion..many will agree, i'm sure some will not...just reserve any comments for your own thinking. TQ.
