Message: <blockquote data-quote="wiramax" data-source="post: 1064201446" data-attributes="member: 45897">hi zthrian,I need an advice on my recent haltech issues. Previously my tuner installed haltech s500 on my 93 sohc NA with no flaw at all. It was wire tap method where he still maintain the stock wiring & all been done in 2days. No issues at all until my Haltech got stolen :( The f***ker cut my harness & stole the unit. Recently i bought back the unit from one of the seller in Sunway, not Haltech dealership. This time around i told my same tuner (who installed the previous haltech s500) to properly minimize the wiring coz since my car now is full time drag race car. But then prob start to arise. I bought the new haltech s500 with complete harness brand new inbox & pass to my tuner. He do as what been told & this prob start to trigger:-a) When we rev carefully the car will rev normally, but if we step hardly it will cut the fueling @2-3k rpm. When we connect the unit to the laptop all the sensor runs fine but when we press hardly we can see clearly the sensor readout fuel cut.b) We suspect the tps faulty, but when we swap from other car tps (same unit) the problem still therec) Then we thought it was grounding issues, so we add more ground cables etc, prob solve for few hours but when we want dyno run the car, the problem still there.d) My tuner pull the wiring more the 5 times to recheck the whole wiring, but the prob is still there.e) When we connect the haltech unit to the laptop- all the sensors can be read. We thought our haltech unit got problem, but the readout seems normal.f) My tuner recently check my 275cc eterna injector with multimeter & he said all 4 injectors reading is 3ohms. I understand haltech s500 required 8ohms onwards for injector , but from my experience eterna injector is high impendance, & previously i been using the same injector before my haltech unit been stolen.Here are my question:- 1.Do u guys think my haltech s500 unit is faulty?2.Or is it a wiring issues?3.Or my injector issues? But on my previous haltech, it has no prob at all. 4. Is there any fakes haltech unit? ( if u guys ever heard of it)Sorry for the long stories, but i still facing this problem & my car stuck for almost 2 months now :(</blockquote>
