KL36 ECU PROBLEMS
Posted: May 23rd, 2007, 11:15 pm
Hey guys i need a little bit of help
i got a 92 gs with klze , cai and a kl02 mass air flow sensor , plugs wires were ordered for probe. k8 disty and o2s and stock 1.8 fuel pump with new filter / fuel lines. Probe Y pipe on with stock cat and cat back exhaust 2 1/4 " I am trying to run it with kl36 ecu but the car idles at a low rpm 630 -650 ( kinda low should be up around 700) off idle accel is really sluggish barly accelarate up to almost 3k rpm then it starts pulling . If you punch it in any gear at higher rpms 4.5+ the car hesitates pulls hesitates then starts going real hard .
Here is what i checked so far :
- idle been set to 10 deg BTDC
- TPS been set according to the site, used analog multimeter + feeler gauges checked voltage reading after all that it was within range.
- fuel pressure was 65+ psi at pump
- tried adjusting idle screw to get rpm higher at idle but it woulndt go any higher than 650
- removed vacum line from pressure regulator to see if max fuel pressure would change anything .
- no check engine light on
- no vacuum leaks
i may forgot to mention a few things but i doubt it
ask me question plz and if anyone got some suggestion plz feel free to say it im really lost and its kinda frostrating
Only thing i can think of is changing o2 from 1.8 to 2.5 L but i dont think they read differently, havent checked unless my old ones are faulty hmm.. they are expensive tho.
