Default Re: RPM surge at start?

Okay, I was looking through the changes again and came across this:

Quote:
Fuel/PE/Open Loop Base AF by Coolant Temp: Modify all between 86 and 158 deg to 11.7, then go back and modify all between 176 and 212 deg to 11.6.
I did notice that the car smelled very rich at start up. I think this may be my answer. I'm going to go back to stock in that table. If that fixes it, maybe I can find more reasonable settings as I may be nearly flooding it during start.

Any reason this table is like this? Some pointers with it?

Edit: Never mind, that's PE mode. Way off base. To help everyone out, here's all the changes made in the fuel folder...

Quote:
Fuel/AE/AE_TPS_Re-Allow: Set to 30 (This is the value the TPS must be below to allow AE mode. Since we will be changing the PE to 30%, we don’t want AE active when PE is engaged.
Fuel/AE/AE_MPH_Modifier: Change all values to 1.
Fuel/AE/AE_Enrichment: Change all values by 108%. Now I like my tables with a clean look, so I only have 2 decimal places. I delete everything after the 2nd decimal place, but this is personal preference.
Fuel/Fuel Injector/Injector_Flow_Rate: Import the file needed for your setup. If you are stock, leave it stock. If you have 42.5 then import that file.
Fuel/Fuel Injector/Injector_Skew_Percent: If you have checked your plugs and have a skew % already, use that value. If not set 3 and 4 to 100% and 1,2,5 & 6 to 96%. The idea here is that since 3 and 4 are in the middle of the engine and are the pistons that crack more often it could be due to higher cylinder temps since they have more surface area bordering other cylinders than the other cylinders. You should check your plugs and set this according to what the plugs show and not use a generic figure.
Fuel/MAF/MAF_Airflow_Table: If your stock, leave it stock, if you have an aftermarket, import the appropriate file.
Fuel/PE/Open Loop Base AF by Coolant Temp: Modify all between 86 and 158 deg to 11.7, then go back and modify all between 176 and 212 deg to 11.6.
Fuel/PE/Base_PE_A/F: Modify all between 86 and 158 deg to 11.7, then go back and modify all between 176 and 212 deg to 11.6.
Fuel/PE/PE_Enable_TPS: Set all to 30% TPS to enable PE
Fuel/Torque Mgmt/Torque_Abuse_A/F: Set this to 11.6
Fuel/Torque Mgmt/Torque_Abuse_Differential_Score: Set this to 11.6
Fuel/Torque Mgmt/Traction_Control_Desired_A/F: Set all to 11.6
Fuel/Torque Mgmt/Torque_Abuse_Drive_Injector_Disable: Set to 0 (we never want injectors to shut off)
Fuel/Torque Mgmt/Torque_Differential_Score_Injector_Disable: Set to 0
Fuel/Torque Mgmt/Traction_Disable_Injectors: Set all to 0
For the High MPH, I set the numbers for a natural progression. Even though we will never hit 252 mph, I want no complications later on down the road.
Fuel/Torque Mgmt/Disable_All_Injectors_High_MPH: Set all High to 255. Set all Low to 254.
Fuel/Torque Mgmt/Disable_1_Injector_High_MPH: Set to 252.
Fuel/Torque Mgmt/Diable_2_Injectors_High_MPH: Set to 253.
Fuel/Torque Mgmt/High_RPM_Fuel_Cutoff: Set High to 6250. Set Low to 6249.
