Ecu/Vaf testing
Ecu/Vaf testing
This is just an FYI. Ok well I have a 92 Mx3 with a ZE in it. It is time for emissions testing so I have to get the car to pass. I have both the K8 vaf(JE50), the KL vaf(KL02), the K801 ecu, the KL01 ecu and the KL31 ecu.
Ok first off the best ecu/vaf combo for performance on this engine was the KL31 ecu and JE50 vaf.
Not suprisingly the K801 ecu/JE50 vaf was the worst. The wierd thing is that the K801 ecu and KL02 vaf ran the motor better than the KL01 ecu and KL02 vaf.
So long story short if you are going to invest in an ecu on your ZE the Jspec is still the best route but if you just don't have the money go to the junkyard and pull off the air sensor on a 2.5 liter 93-97 Probe/Mx-6/626.
This is all just by how the car felt there was no dyno testing so I cannot verify my findings to be true, yet. I am going to the track tommorow night so I can give you track numbers at least. Lata.

Re: Ecu/Vaf testing
I think mx-3's generally run pretty clean. I hollowed out my cat and I still passed.
Re: Ecu/Vaf testing
yo! lazzie what is this 2.5 air sensor are you talking about?,can please post a picture so when i go to the junkyard i can get one.thanks
Re: Ecu/Vaf testing
this question is for lazzie. which ecu would you run with the 2.5 air sensor?

Re: Ecu/Vaf testing
The K8 ECU, Most MX3ers run K8 ECU with KLDE/03 VAF when they swap to a 2.5l. Some though have gotten their cars to run better on the KLDE ECU & VAF combination.

Re: Ecu/Vaf testing
The 2.5 liter vaf looks just like your stock one it just says kl-02 on it hence why I posted the part number :p

Re: Ecu/Vaf testing
best combo with kl-ze engine is kl-ze ecu and stock vaf or 1.8L ecu and 2.5L vaf
Re: Ecu/Vaf testing
so which one is the best set up for klze, the 1.8 ecu with 2.5 vaf or the 2.5 ecu with 2.5 vaf.
Re: Ecu/Vaf testing
Sorry to double post just wanted to know what combo lazzyie used topass emissions, i dont think you ever got tothat Shawn
65 shot > V8
Re: Ecu/Vaf testing
Haven't done emissions yet. As for 1/8 mile track times I ran a best of 9.6 on the Ze ecu/vaf, a 10.0 on the k8ecu/Klvaf, 10.2 on the kl ecu/vaf. I didnt bother with the k8 ecu/k8 vaf. Ran 5 runs on each combo. Just more fyi... I'll let everyone know how emissions go next week.

Re: Ecu/Vaf testing
i though that the klze ecu and the 1.8vaf was the best for performance?

Re: Ecu/Vaf testing
The 1.8 vaf is the same as the ze vaf
