car starts good, idles, but doesnt rev
So been working on adaptronic for a while now, and by modifying the base map, with the help of other maps, and the instructions, I was able to get it to start up fine, and idle fine, but now I'm having two issues, and I've pretty much hit a wall. Car runs super rich around 9-11 @ idle. The idle keeps fluctuating from about 900-1100, it keeps revving up and down without any throttle input from me. It's also really hesitant reeving up. If anoyone could help or point me in the right direction it would be awesome, also if anyone knows a place where I can read more about fuel maps and how to tune them, that would also be super helpful. Attaching my current ecu map to this, thanks in advanced.

Assuming your engine idles between the 26 kpa and 40 kpa bins, you have way too much fuel on these cells and probably on higher loads. If you are far away from the optimal numbers, rapid learning mode is not going to help.
12ms @ 56kpa is a lot of fuel even for stock injectors.
Is your map sensor properly calibrated?

First things first, did u try using my map from my guide?
Seeing that you're in ms instead of VE, I'm guessing you took one of the files in the Instructions folder and those are crap/wrong..
Next you might want to add little bit of background on what you're running.
As said above if your map sensor is calibrated properly, you're flooding that motor.

Yeah I ended up using the stock injectors file that came with it, but I ended up changing everything because it wouldn't even start up on that.
-the car has I/H/E other than that its stock, I figured I should get the car running good on stock injectors before I install everything.

Ok so I tried to re-calibrated the sensor according to the instructions. Made the lower 16kPa, then hit learn, that worked. For max I hit 300, but when I disconnected the vacuum, and it doesn't read 100kPa, it just keeps fluctuating from 16-300, never stops just keeps moving rapidly. Could there be something wrong with the sensor? Or is there something I'm missing? I rechecked all the wiring, and that seems good.
Instead of the low ADC being 154, and the high ADC being 3384, mine reads 1208 and 1210.
I tired your map again too, and it refused to idle, only way I could get it to idle was to lower the fuel map by 60%, then it idled, but it was real low at around 400rpm, and I couldn't get it normal no matter what I tired. ahhh this is so frustrating. Just wanna drive haha

No your recalibration is wrong.
You need to apply the correct pressure/vacuum to the sensor and then hit learn, same with the high 300kpa and then hit learn. I'm assuming you just clicked learn with the sensor at atmospheric pressure. The sensor is a range. If the range is off it wont read 100 while at rest. For example your vacuum is correct but the pressure is wrong, your atmospheric pressure will be somewhere within the range but not at 100kpa.
What map sensor did you order the 1 bar or the 3 bar one?
Did you do what i did on the harness or are you using the adaptronic ecu to idle?
Also you're tunning in ms NOT in VE so my fuel numbers would be VERY different.
60 ve is not 60ms of fuel...

Did not do what you did with the harness.
Yeah I understand, I used your map, didn't override mine with your data.

Personally i'd save the map u have now and then over ride the settings with my map. I've done everything you need to tune the ecu. The reason why it didnt want to idle is that my settings are set to idle with the stock ecu controlling the idle (YOU WANT THIS IF YOU WANT TO KEEP YOUR BRAIN SANE)
To make my file idle with your settings, copy your idle settings into my file at the idle tab, change the aux 1 to idle control PWM @ 1kHz in the aux out tab. This will enable the adaptronic idle control.

Calibrating the sensor is simple however not many have the tools. You need a vacuum device that has a gauge that says how much vacuum its pulling. You need to vacuum the sensor to the correct vacuum. Say you want 15 to be the minimum, set that as minimum value on your adaptronic screen and click learn.
Calibrating the high. You need a pump that can put out 200kpa over atmospheric pressure so thats 300 total absolute kpa. Pump the sensor up to 300 absolute kpa and hit learn. That will be 300 kpa.

latest map, with the help of triple88a, we got his map setup to where it should work, but it cranks up, and dies immediately after, can't seem to figure out why. I've tried to add fuel in the master trim but that doesn't seem to help. I'm attaching the file to this. So ******* frustrating, if anyone have any ideas let me know it would be greatly appreciated

Tried to set my idel min value realy high, also upped my ms for cranking. It still does the same thing, can't seem to figure it out. The weird thing is, now when if I'm blimping the trottle after starting, it seems to be fine, and looks like will run file till I let go, once I relece the throttle it flutters around 500 and then dies. I also changed my plugs and wires out with new NGK ones, just incase it was something random. Took a log this time of a couple of attempts. Also took a log this time attaching it to this. Any ideas?

Open up the idle valve more. Go up to 110 minimum and 110 on the maximum.
The motor is idling at good afr however too little air is getting by. My guess would be the idle screw is closed up too much which is why you need such a high idle air control value.
If 110 works better you can try opening the idle screw on the passenger side of the throttle body. My guess is yours is almost closed.
Whats happening is for the first few seconds the effort after cranking is keeping it idling... when that goes to 0 (normal) it dies.
One more thing, go to the corrections tab and change ignition corrections mode to open loop.

Thanks dude, I opened the idle screw, and that did it! I was finally able to idle it for like 10minutes straight.
