What he said. Worked for me as well.

thanks guys. God bless this forum! Now I just will have to wait for a can scan and cable/software etc to get here. Man I miss the old days when I could just turn the distributor and mess with the carbs to tune! (other things too of course I m just keeping it simple). Course in those days we didnt have a forum like this to share all this great info either.
i appreciate it guys.

Does this also apply with the stage 1 map? I just turned my unit off and the stutter / hesitation went away. I have the canzoomer software & special usb-type cable, but not the CANScan yet.

 

If there is any advance on the first column ( effects everything below 4.4K) on some cars it will not like it. Make the first column on the left all zero's......should get rid of the stutter at low throttle/RPM.

You can try decreasing it a few deg at a time....but I tuned mine down in this area and it worked better

 

I don't know about this map. I have been running my car with this map. It is doing okay w/o knocks and ping. Using shell vpower gas 93 octane. seem to be leaned but I'm not sure, is there something wrong with this map. give me your input please. .......... hopefully I'm doing the maps and chart right so you can read them. 1st time. also I had to write the last column because I could not get it all on the paper. .............1/2 scale for rpm. these are zipped files copy them then open.

 

sorry i dont know how to post pictures

 

What map are you running and how does the car run?

Vince

 

i used a stage 1 map that i got from canzoom then I adjusted that map. the car run good I would like to put the graph on the thread but when i try to upload from the computer i get a message that say i dont have authorization.

 

I have the graph, for some reason I cant post it on the thread. I would love for everyone to see it. Maybe if somebody can instruct my on the proper way to do it.
When i made a copy of the graph, the damn thing is 10mb. that is big. it is in jpeg format

 

I just copied the image into paint using print screen and then saved the file as a gif image. It will be less than 100k.

Here is mine..

Ha! thank you guys I got it now. the file was too big. hope it work now

 

Damn thats aggressive

I dont think I am going to push mine that far... I liked your graph Jason.. It was very linear and predictable... Did you share that map earlier in the thread or are you selling it on the parts for sale page... :p

 

Jason Hamilton
If I'm running too lean. and I do feel more power. I drive my car aggressive shitfting gear in 6000 rpm range. I burn more fuel but I like the feel. You say that this is not good what do you mean. Will it blow my engine or something like that. I'm a newbie at this stuff and I do like the feel but i don't want to blowup anything. if it reduces the cat's life only , than i'm not worried. the car is running fine,idling fine, no pings, knocks. using 93octane shell vpower only. 13k miles. using this map for 2 months. what happens with a RX8 running too lean.

 

ok I will make it not so lean. Iwill try to go out tonight and adjust my map

thank you for the info. I have not driven the car in 2 weeks

 

His car went lean at the end of his graph most likely because he got off of the gas. I would make another run and see if that repeats - my guess is it won't as i don't see anything in his map that would cause a spike like that.

I would tone things down a bit around 6600 rpms when you get the teriary ports closing and an instant of very lean conditions. Your timing advance is also pushing the limits so make sure you always fill up with some good gas.

 

That is correct about the graph i did take my foot off the gas. See i have the laptop,in the driver seat and trying to push the stop button ,watching traffic,looking at rpm gauge, ithink Iwill have to do this with someone in the car with me. I have been running alone at night.

 

I would check 3rd gear....I agree with Jason....overall too lean..esp 8K area. I tuned mine to give me 13.6 and 13.2 above 8K. Watch 4th and fifth...they seem to run a leaner map under load.....they may go very lean on you with second that lean

 

Oh you already did in this post.. Got it.. thankx

 

When you say you changed the scale from half RPM to full RPM...are you talking about the scale when editing the CZ map itself using the EManage software...while plugged into the CZ unit itself?

 

He's talking about the daughter board inside your Canzoomer unit. His write up explains how to do it.

Rev_2_9K and I have been experimenting with different maps for his CZ box for about the last 2 weeks. We’ve gotten pretty familiar with the canscan software and the emanage program, but we are having issues with getting consistent logs of our runs. We use the same map, but yet its like the ECU somehow learns what were doing and overrides the emanage. So in other words, we could get the A/F in the nice 13.xxx’s and then two days later its down in the low 12’s, with the same map.

1. Who else has been getting these kinds of inconsistencies? Do most of you guys get a good map to be stable and log consistent A/F’s?
2. We have been getting a A/F spike in the 17-18 range at about 6200-6400rpm, that we can’t seem to dial out. Even with the map set pretty low (in the 10-15 range) this is still an issue. How much of an effect do you guys notice from the port opening.
3. Rev’s unit is currently operating in the ½ RPM mode, would altering the unit improve our consistency issues (can’t really see how but….) or just make the math in our head easier?
4. Can the ignition maps cause issues? I believe Rev is running the most aggressive ignition map from CZ while we are trying to tune the A/F.
5. How important is the partial throttle portion of the map?

Our biggest issue is really getting a map to return consistent canscan logs over time. I know that the emanage must be able to work consistently, or the greddy turbo kit among others would have real issues. Its really frustrating to spend hours tweaking a map to only see it made useless two days later in our logs.

I appreciate your insight on this.

 

Same problem over in the auto tuning thread. After the ECU undoes your map, what happens if you turn off the unit? Does the A/F really go into the toilet?

 

I can't really be much help here, as once I got the map to where I liked it, I haven't done much monitoring of it with my CanScan. Guess I need to check it.

Damned if this blasted PCM doesn't seem like it's too smart for it's own good!

 

I would be very appreciative if you could log your car and see if your map is still holding true. Are you tuning at half rpm or full?

I'm wondering if you get to aggressive if the car somehow changes the mixture, I don't see how thats possible if your in open loop and your able to change the maf voltage, but who knows.

In addition, the base CZ maps seem really weak given that to get our results, we were using 35-43 at one point to get our results, is that them just being conservative?

 

I did today, recheck. Mine catscan graph looks identical to stock car with no CZ. Bummer, I am wondering if I am doing something wrong, or perhpas it is true the PCM is sensing the change, and adjusting the fuel. Now I have 0 gain. I am wondering how long it takes for the PCM to sense the new maps? We need Maurice's help on this one.
