Yeah that's why you need the software upgrade. There should not be any negative numbers in your fuel map.
A word on using the alky. Your combo is not much different than mine. Set the alky at 8 psi, that will be the point at which it starts to activate. Don't worry it's progressive. Turn the gain knob to 6 and let it do it's thing. Remember this when trying to tune with alky, you will end up trimming the fuel map to compensate for the alky being sprayed into the motor. Meaning your VE numbers will decrease under more boost. Shoot for an AF ratio of 11 to 1 to make power, above 13 psi or so. Keep the timing conservative and get the fuel map right first, you can increase timing later.
When you add methanol fuel you end up reducing the amount of gasoline being injected by 15% or so on the VE table. Methanol cools the intake charge which keeps detonation away has an octane rating of 106 which means more boost and timing.
Set up your data logger with just the parameters you need. KPA is a must, PSIG, rpm, Fuel correction. You can name the dash and then select it to data log with. You can select different sensors to trigger the datalog. Personally F8, and then the space bar works for me. Then I make my run.
Once you see where you are at you can reduce or trim the VE table to get to the desired AF ratios and get the WB corrections within 1 to 2 %. Overlay your datalog over the VE table it will show exactly which cells to adjust. Look at the correction percentages to guide your changes. If you are 10% rich in certain cells reduce the VE numbers in that cell by 10%
A note about your VE map as a whole, if you make drastic changes in certain cells and the surrounding cells are way higher or lower the motor may surge or buck. A smooth fuel map makes for a smooth running motor. I'm talking about big changes, the FAST unit can handle a lot so don't be afraid to make changes. Read up on percentage trim (positive or negative) and interpolation. It's in the HELP files.
Alky and pump gas work really well but it took me a long time to figure it out. You can too.
