I've bought a cz stage 1 recently, after i installed the unit in my car, it seens losing hp at the low rpm, and it goes up slightly slow, dun know what happaned....... plz give me some adives guys....

 

Post your map please.

Sorry , didnt have time to do the map yet. And also i just wonder if i really have to turn the unit before i can actually get the power?

 

This has to do with the 2 capacitors that some of us needed to remove. And then change the ignition map to have 0 value at the lower left corner. I can't believe CZ still continues to sell it with that setting. Hey CZ! Ignition changes at lower RPMs causes lowers power for this machine! If any modifications are to be applied down low, it should be airflow only or nothing.

 

Thx guys, hopefully, i can make it happen by ur advises^^

 

I get the some behavior when I finally installed my CZ : my car is slower with the CZ even with the latest stage 2 map. My CZ is part of the GB #2. I follow all the instruction from JasonHamilton web pages (cut the 2 capacitors and move the brown wire to the full rpm mode). I'm using the CanScan tool from Harrison to log the infos from the OBD II plug. As you can see on the maps, I'm running richer with the CZ ??! It seems also that the CZ is doing something under the 5'000 rpm ...
I did some 0-100km/h runs and I was slower of about 1 seconde with the CZ
Any advice ?

 

Wow thats very rich. How about removing some of the fuel in the stage two map say -10 in the worst spots and try again.

I was thinking using the stage 2 map will at least increase performance. But now, I think the european RX8 have not really the same settings, regarding the mixture table
Maybe I can try to make a graph with everything to zero (AFR & Timing) and I should have the same graph as without the CZ. So, that way, can I be sure the CZ is working well ? What do you think ?

A dummy question : on the e-manage AFR map, a positive number will make the mixture richer (in %) ? Is that correct ?

 

The higher the number is, the less fuel is added to the car. It tricks it into thinking that their is more air going into the engine so it cuts back fuel.

Thats the way I understand it. The higher the number, the higher AFR in that data range.

 

Ok guys, thank you for those explanations ! I'll do some more tests during the following days and post the result.
