yes someone has a toggle for the eprom

[lucas240sx]

whats the toggle switch for?

[curbhuggerrps13]

could be different maps for timing,fuel, alcohol. many things...maybe lasers.

[lucas240sx]

how can i find out the exact tune on this ecu?

[curbhuggerrps13]

u wont know till you have someone who has a eprom burner or programmer. they have to remove the rom and put it on a reader kinda like a sd card reader. then it should display the parameters of the ecu

well hopefully i can find someone locally
thx for the help!
