Rev limiter
Looking to put a rev limiter on my C5 LS1. Not really concerned with launch control but all I see is the combo 2 step types. I have an automatic and not drag racing it but if I do an occasional burn out, I don’t want to over rev it. Any help or recommendations will be greatly appreciated.

that can be set in the tune, you could probably find someone to do it for less than what one of those boxes costs

I had A&A Corvette in Oxnard CA set the rev limit on my car at the same time they also set shift points for the A4 because of the new 3.73 rear drive ratio, also set fan off and on points lower.

Since you didn't indicate any mods, etc I am assuming it's stock so far?

If you get HP Tuners this is where you can change your RPM limiter. If you have a cam and what not they may have increased your limiter to take advantage of the top end power gains but this is where you would check and make any changes you wanted to.

OEM!! ALL C5s have a rev limiter programmed into the PCM from GM. As Ron said, it's 'adjustable'. A4 cars can pick up some good gains in ET and mph. The 4L60E has a very low first gear, and has a pretty large drop in rpm when shifted from first to second gear. Probably go from around 6200rpm at the top of first gear, down to 3,500-3,800rpm in second. If you gain 300-400rpm in first, you'll hit second at 300-400 more rpm. Most LS motors are making more torque/hp at 4,000+rpm that at 3,700rpm.......

He has an auto.
And yes, all tuning is done through the OBD port.
Since it’s modified with a cam, headers etc and has been dyno tuned, it may also have a stall converter. Stock stall sucks when you add a cam.
OP, just fog the bags at will. It won’t blow up unless it’s in sad shape.
6800 is fine for a rev limit on these.
