99 C5 rev limiter questions??

[LostCause]

Is it possible to only pull spark to limit rpm.. If so how do I accomplish this..I dont want to fuel limit the motor on the bottle. Thanks

Hello LostCause,

Believe LS1-B PCM rev limiter is fuel or ETC (throttle) only - no spark option.

E38 & E67 have fuel / ETC / spark as rev limiter options.

Taz,

he could do what a lot of the E38 truck ECM's do with the HOT, just drop timing down to a minimum value at the rpm limit(?)
