Lantis with KLZE using KLK1 ecu - just transplanted in

kfze · 10-07-2008, 11:12 PM

Guys,
I just put in my KLZE-curved neck into my Lantis. The engine uses a KL68 throttle body, KL47 MAF airflow sensor together with the heat temp sensor at the airbox, as well as full engine wiring harness.

The curved-neck KLZE has a higher intake manifolds, but it fits the lantis perfectly, although the engine now is slightly nearer to the firewall. The engine comes with the KLK1 ecu. I have rewired all the harness and using the KLK1 ecu on my ride.

Initially, I have few complications i.e. no reading on speedo, no reading on RPM meter, aircon as well fan, as I have difficulty locating the exact wiring point for all these. After spending about 5 days, I have managed to wired up everything.

All the important sensors are working as it should be, means water temp, ignition, fan switch, VRIS.

How do the engine feel ? Well, its sluggish ! It feels like the engine is running lean, means the throttle response is lagging. I am using my original KF 2.0 fuel pump in my setup (a mate of mine also using the same fuel pump on his MX3 KLZE).

Complications :
1) Idling without A/C is above 1k rpm. With A/C on, the idling DROP to 800rpm. I have tried to adjust the TB to set the idling speed at 750rpm without A/C, but when I turned on the A/C, the idling rattles (means its hunting to stay idle). At the end the engine just died....

2) I have driven my buddy's MX3 with the same engine but using KL31 ecu and JE50 airflow. I can tell its a world of difference. His MX3 runs like a water, very smooth and fast ! While mine feels like I am pulling a bull. I can say my KFZE type R engine is much lighter and quicker than my KLZE now...

I believe my engine comes from Mazda Eunos 800 or Millenia (both these cars using curved-neck KLZE in Japan).

Has anyone that transplanted the ZE has the problems that I faced ?
Based on my description, can anyone offers me some suggestion on what to lookout for so that I can release the hidden powers of the KLZE.... as well as to make the car idles properly ?

Any suggestion is much appreciated.

Thanks.
