Lantis with KLZE using KLK1 ecu - just transplanted in
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. |

IF you can use the ECU diagnostics you can then work out where your going wrong. Sluggish sounds like igniton retard and that could be a number of reasons.

Problem solved. The problem related to aircon wiring and compressor grounding (something about there as I did not understand some of the jargons that my mechanic used) Now I really feel the power of KLZE. I remembered testing the car after rectifying the problem and I came out of the car laughing and smilling all the way. My 2 other frens who droved turbos after came out and smiling.
It pulls like a turbo. Really wonderful and fully satisfied. |

You will be laughing too after u taste the power. By the way, what engine and ECU are u using ? Are u gonna rewire the whole thing too or u just plug n play with your original KF wiring
I think based on your 1060kg weight, u may be using a MX3 instead of a Lantis. |

no its going into a BG Astina GT ,so 1060kgs
using a MX3 loom, KL28 ecu and KL01 AFM as its all i can find so i'll be down on some power untill i can find the correct ECU combo no need to splice wires as the MX3 is the same dash connectors as any BG based mazda
