the graph looks very good.

just to give you an idea on where your AFR should be - see the green line that goes up and down? The bottom of that is the safe AFR range, the top of it is the extreme AFR range. If you can get your AFR somewhere within that, or close to it, you'll see a nice improvement in power.

davefzr

Dang that does look good. I have the CZ and I am jealous of your AFR haha.. I wouldnt change a thing if your happy with it.

davefzr

Hey Jason, I was having some rough idle problems and the throtle was hesitating at idle when I gave it gas so I had to take my CZ unit out. When you told me to look at the ignition map do you mean the Air Flow map at the 0 measurement? I take it that the 0 to 100 is the throttle position and the rpm along the top is obviously your rpm. So did you want me to look at that map and change all values to 0? Or was I supposed to change this somewhere else?

davefzr

or anyone

Two maps....A/F ( the one with TP and RPM) and Ign map ( MAF Voltage and RPM)

Adjust the first column (left) to all zeros......on both maps will give you no adjustments below that RPM on the maps...and on some cars...better idle.

I had problems with mine idling before the Caps were removed...is yours up to date inside??

mysql101

in the greddy emanage, you will only have two maps to work with, one is afr, the other is ignition. In the options, you should be able to enable an option called map trace. So when your car is up and running, watch what cells are highlighted in the ignition map. If it's highlighting cells that have a non-zero value at idle, it will likely be giving you a rough idle or hesitation. Change them to zero.

davefzr

oh sweet thankx guys.. I was having really bad idle.. I'll try it out tomorrow. I was even unaware that you could perform a trace against the car while it was running. Thats why I was so confused when you asked me to do that map trace. It would have been nice to have a manual to accompany the E-Manage software.

davefzr

Hey, when you talk about the throttle position setup on your web page, are there any other parameters or settings that we need to change before we use start using the CZ? I noticed something about the AAV RPM Setup, Injector setup, etc.. Do we need to concern ourselves at all with this, or will simply setting up the throttle position on this page be sufficient? Maybe if you could post your parameter settings page, if there are other changes, that would really be a big help.

AAV setup is not used...same with sub injector maps etc....until you go FI

lets talk about this throttle calibration.

i did this on Saturday based only on the 2 sentances they gave me in the help menu.

car was tuned to on but not running.

i selected test throttle.
it took a voltage reading at 0%.
it told me to push throttle to 100%.
i pushed the gas pedal to the floor.
it said it was finished.
i hit confirm.

it gave me no indication what the 100% throttle voltage was.

i do not know if this setting is saved per map or sent to the unit. so if i load up a new map do i have to re-calibrate.

mysql101

the only thing you need to mess with in those menus is the throttle calibration. You don't need to save or export, it's saved automatically.

Same goes for maps, you don't need to export them (I used to export). When you make a change in any cell, it's automatically saved to the unit. I was doing research and found some people (with other cars, not the rx-8) were having serious issues specifically because they were exporting. With that said, I've exported without issue, but there is no need to do it.

For the record, my throttle position even at 100% with foot all the way down, only records a 99% in the e-manage software. I just changed my map scale to show max at 99 instead of 100.

davefzr

What..?? We will get issues when exporting? How strange is that. I have been modifying the map in my house not connected to the car, and then when I feel the map is ready, I export it to the CZ unit. Are you saying that it's a better practice to update your map when it's directly connected to the CZ unit to avoid any issues? Then, because it is directly connected these changes will automatically apply itself to the unit?

mysql101

i personally have not had any issues exporting, but I have read that some people have (car ran funny - and someone replied back saying NEVER EVER EXPORT).

I do all my changes in car, would take too long to do canscan runs and cz updates if I had to return home.

davefzr

Hey, thankx for your input guys! I reinstalled my cz unit tonight, calibrated the throttle and adjusted the first column to all zeros. I just got back from one of my three rides tonight, haha.. and my car now idles fine and runs great.

Thankx again guys.

So what map did you end up using?

rev-2-9k

My map is having some issues. I run in closed loop till about 5.5k at near stochiometric. When i go in to open loop at 5.5k all the way till 6.5k i am having variance in my maps between differant runs. 6.5k till 8.5k is looking good between 13.2 and 13.5. Above 8.5k (which i don't care about) i shoot above 14.

Some runs my problem area (5.5-6.5) i run a nice tuned map at 13.2-13.4 the next run on the same map i might run as rich as 12.6. It bugs me that i have this variance between runs, but i am keeping my maps so the lean runs are still safe and the rich runs are till much better than stock.

I pretty much need to buy a 10' USB extension cable to start fooling with the iginition map right? I am currently using a 1/2 scale CZ stage 2 map. I have verifed that my MAF voltages are on the same scale.

davefzr

I ended up using the Stage 2 map supplied by Jason in the "Share your Maps" thread...

RX3+5

I'm running the same map but at half scale and had to zero out the same cells. I found that the stage two map likes higher octane if you can get it!

Vince

nhk

rev-2-9k, I think I have the same problem with 5-5.5k rpm. I already zero out all my maps cell to take collect some stock data with the cz unit on.

Btw, my is 05 model.

nhk

davefzr

Yeah.. I ended up changing my CZ unit to Full RPM so I could just use it directly. It's really not that hard, just need to be brave enough to open up your new CZ unit to modify it (which I barely was)..

davefzr

Why do you have to even have ignition advance changes? Couldnt you just set all of the values to 0 so that there is never a chance of the factory settings changing?

Additional advance (within reason) will give you more power in some areas, as long as you don't cause ping. If it is really lean...it tends to ping easier...so watch that you don't advance too much in any area that tends to lean out. If you look at the CZ Maps....the advance drops when the APV opens at about 6250 rpms...as there is a leaning tendancy there for it to go lean..just before it goes back to pig rich. VDI opens at about 7300RPM...also a leaning tendancy.

davefzr

I think I may have too much advance actually. As I drive I notice the car is jerky in some rpm areas. This is probably the cause of how much advance is used with the stage 2 map. It really uses a lot!! There is almost a change in every cell. I think I am going to scale this back a whole lot and see if it clears up the issue.

dannobre

iTrader: (3)

I decreased my advance a bit at lower RPM and airflow....and it seemed to tolerate more above about 6600 and higher flows. A lot of the cells in the A/F map are not used. Set your map trace on continuous and see what I mean.

davefzr

Well.. here is what I found. I changed my ignition map to all zeros and the problem still persisted. you can really tell the difference between ignition tuning and without. With it, the car is a lot more responsive so I think I am going to add some back. The only thing that fixed my issue is applying zeros to every single rpm below throttle position 70 (60 - 0) on the AFR map. This completely solved any issues I had. The next thing to do is to add back the ignition advance very slowly and continue to increase my AFR. I logged some data tonight and the AFR is finally above 12 and approaching 13.
