What makes the 98-00 PCM "so bad"?

[N0DIH]

I am thinking of swapping the PCM on my 99 K2500 Burb to a 0411, but wonder if the 98-00's are really that bad? Nothing can be much worse than my 99's 98-00 Vortec VCM can it?

I am not planning on custom OS's, just daily driving a 454 with a 4L80E. I am thinking of using the L21 front cover and crank sensor if I can install it without removing crank to put on wheel...

Don't know about the burbs, but in the LS1 F bodies the 99 and up pcm's are the good ones. The 98's have the lower resolution in the ve tables and will not accept custom operating systems. Sorry not much help.

Maybe I missed the years, 97-98...

Just wondering if they are worth using at all. I don't really need custom OS on the burb, just wondering if it is worth using the 98-99 PCM and EFILive (looking to get soon) in my Burb vs using a 99-up PCM....

I would go for an 0411 swap if you do it, basically you can get finer control of your engine from what I understand.

I think there is info on here about the swap. Changing pinouts on the connectors plus a couple of other little issues. But the guys who have done it say its well worth it.

That is what I have heard, 4 hours of work or so. I was just thinking if the 97-98 isn't THAT bad, (I don't need custom OS, it is a truck 454 mostly all stock, not like I am racing it....) and I wouldn't blow away a VIN license for using EFILive on it.

Honestly, strictly financial in motives... But if there is enough good reason to use the 0411, then I would just go that way, just trying to be financially concious in this day....

Im pretty sure you'll blow a VIN license either way, only the 97-98 LS1s are free, all the Vortecs need to be licensed.

And....you can't tune the black box 'truck' (Vortec) PCM's with EFILive from what I understand anyway.

[N0DIH]

They 98-00's are supported now, for about a year or so...

The 96-97's aren't, but the 98-00's are....
