For some reason quite a few people that I have talked with have had to scale there 440s to around 360 range including myself I dont know why and I tried running the recommended scaling but I could never get it to work I had to put it at 360.

This can also cause the computer to try yanking fuel out of the low trim too much causing lean spots at the transition point where the computer switches back to opwn loop.

Resolution:
Reset you battery for 1 minute to clear fuel trims.

Put your car's into full time open loop by setting the open loop load settings to 10 across the board. This is low enough the car will never see closed loop. Next verify your injector CC setting. Once your positive its pretty close say a 440cc injector should be rated near 416cc at 42psi of fuel pressure like we run.

If its lean drop the latency of the injectors by selecting the whole right hand side and using the "*" key to multiply it by some percentage say we see something pretty bad like 12AFR at idle lets increase the the latency to lean it out by "*" then using a value like 0.85 so we removed 15% of the latency and thus 15% of the possible fuel the injector will try to add to the engine. The opposite is true with 1.15 we would add 15% of latency and thus 15% more fuel. Once the injector is stable at 14.7AFR its time for a drive.

First try a short drive with the car in open loop. See if you get lean spikes or rich spikes comparatively to whats actually in the AFRMap value at the time. If your rich then you need to increase the CC value of the injector and visa versa is true.

Once you get it running fair in the open loop disable it and run a test drive.

4.69v--- 2.592
7.03v ---2.208
9.38v----1.2
11.72v---0.744
14.06v---0.6
16.41v---0.6
18.68v----0.144
Scaling is at 360

I can switch those right now and make another copy saying flash this here and I will let you guys know whats up. last thing I need to learn is how to tune so if someone knows a dictionary of tuning words I can learn like open loop, close loop, maf scale etc that would be great stepping stones.

thanks guys I will let you know how it goes in a week and a half taking the bike to work so the car can have a break

I know how to change the latency and injector scaling, the board thing is the hardest part for me and these open loops and close loops because I dont know what those mean. I will look at the map and see if I can grasp what your saying about doing the open load 10 settings.

Since a o2 sensor is only good at reading if the AFR is richer or leaner than 14.7 afr its not useful when trying to run the car at richer trims so the car goes into open loop. At open time it uses the maf sensor, air temp, voltage latency, and rpm to determine how much of fuel pulse the injectors give.

When in closed loop the computer simply uses the above algorithm to get close and then see's if the car is rich or lean via the o2 sensor and makes adjustments. Therefore if you scaling is off the adjustments start getting extreme and when it finally goes back into open loop the adjustments still are in effect so it goes lean or rich then.

make sense?

so this is how im thinking it is, open loop is when the throttle is being pressed down, and closed loop is when the throttle stays the same or the throttle is left off? im understanding the meanings, but if this is correct then i got it

The basic concept of pressing the gas down makes the car go into open loop is pretty true but realize it slightly more complex than that .

You know by now that airflow into the engine is basically load right? Well if you didn't yo do now. So the computer translates the airflow and compares that to the RPM and it generates a load number which is essentially the basis for fuel calculation.

Now on the open loop load table it basically defines an area on the map we want to be in closed loop. Once the loads are above the table's defined limits then it goes into open loop. Easy no?
