1) Fuel multipliers are not "Enabled/Disabled". The option in TurboEDIT GUI is for auto-detection of fuel multipliers. Basically, so TurboEDIT will calculate these multipliers on it's own without you having to know what they are.

2) Here is the explaination I wrote on PGMFI to the same question..

--- begin cut ---

Multipliers are easy to understand..

Think of it like this, the ECU can only calculate 8-bit values 0-255 (0x00 - 0xFF).

The fuel multipliers give the ECU a way to calculate outside that value range.

For example, say we have a fuel multiplier of 0 representing no multiplier at all (in an example equation).

10 * 0 + 10 = 10

Assuming 10 is the "max" value we could use in the ECU, we add a multiplier.

10 * 1 + 10 = 20..
10 * 2 + 10 = 30..

See how the same "max value" is able to be used, but the use of a multiplier lets us get higher values?

Same goes with the fuel mutlipliers. Simply put, they allow us to use higher values in the ECU for the pulse durations.

TurboEDIT doesn't have fuel modifers. It has Fuel Multipliers. :P

Ya well, he's talking about TurboEDIT. :P Get that OBD1 crap out of here.
