I am trying to determine if there is any way to hold the engine at 3000 RPM while I am sitting at the line with the clutch depressed and the throttle at WOT. What I want is the drive by wire throttle to hold the engine steady at 3000 RPM and then as soon as I dump the clutch I want it to snap open to WOT. The car is a 2002 Z06.

Thanks

Get a two stage shift light.

First stage holds the rpm at the tree with pre determained setting.

Second stage is when the light comes on the shift light to shift, to the next gear.

You need to get a 2-step from Lingenfelter. You can set it to limit your launch rpm anywhere you want. If you want to launch at say 4000, just set it for that, then you can mat the go pedal once you stage and the 2 step will hold that rpm until you launch, then it'll allow you to go wot and shift at whatever rpm works best for you. While not a cheap unit, most guys that use them do get pretty good short times and are pretty consistent. One of these is almost a must for bracket racing, especially for a manually shifted car.

I was hoping to program this into the stock computer instead of using a spark cut device. I have a 2002 GMC ENVOY with the I6 and it will hold 3000 RPM in neutral at WOT using the drive by wire throttle. Does anyone know if this can be done the same way on the 2002 Z06?

If it cannot be done I will use the spark cut devices.

a tuner would be able to answer that question, that would require to have the rev limiter based on vss, 0 mph= your set rev limiter.. idk if thats possible, but the gm ECU seems pretty fussy, coming from the honda world were a chipped/tuned ecu can do almost anything, like antilag (for turbo cars), TPS based two step (using gas pedal), full throttle shift, using the CEL as a shift light, etc, all this stuff the factory ecu can do using, neptune & hondata tuners..

I don't believe it can be done with the stock computer.

I have/use the LNC-002 from Lingenfelter. It wires in line with your coil packs and is a pretty easy install. It makes cutting consistant lights/launches easier. It is adjustable in 100 rpm increments from 1000 to 9900 rpm.

Depending on the track/tire/race I set it between 3000 and 4000. It is triggered when the clutch pedal is on the floor. When I release the clutch, Race On...

I only use it when bracket/index racing as an aid to cut a good light. I do not use it for all out ET chasing.

there are aftermarket launch control kits ( computers & clutch release ) but expensive.

i bought a lingenfelter launch controller. its causing a bad misfire at idle. sent the unit back and trying to get my money back but they want a 20% restock fee. apparently it doesnt work with different plugs or plug wires...

im not the first case, check ls1 tech. there is however another brand that makes a 2 step that is more compatible and has caused less issues than the lingenfelter unit
