Re: LT1 SWAP QUESTION

Umm........

What the hell are you talking about? Do you mean the speed limiter in the ECM? I hate to break it to you, but your 305 Camaro should have had that as well...

Anyway, if you ARE talking about the ECM speed limiter, you can disable that by custom ECM tuning on the DIY PROM section. I'm sure they'll show you how.

Or, maybe you're talking about the fact that it won't let you shift through all of the gears unless you're at full throttle?

Anyway, your post confused the f@#$ out of me...

Re: LT1 SWAP QUESTION

If you get an LT1 PCM from an f-body or vette I think the speed limiter was set at 255mph from what I remember from reading mine. As for the skipshift if that makes you shift from 1st to 4th when low rpms that can be taken out of the PCM.

You can always flash the PCM's to whatever you want to (if you get a '94+ PCM, stay away from the '93s)

Re: LT1 SWAP QUESTION

Cars with the Z rated tire option got no speed limiter and the 150 MPH speedometer, without the option you got 115 MPH speedometer or so and a limiter.
