96 to 01 '0411 conversion; S10 4.3 newb ?

If your VSS worked on the Black Box PCM then you should be good to go. Us V-8 guys use the 01-02 Operating systems. I know they have Custom Operating systems for those years---I would probably try to use one of those years.


Hey Stealth---Whats Up

I've been driving on the '0411 for a while and it is much smoother start and idle. The start-up idles down much, much faster then the old black box that seemed like there was a vaccum leak the way the idle "searched" down slowly, but the '0411 snaps quickly, very responsive.

I do have the P0327 KS code that is keeping the revvs from producing good power, holding the timing back. I would appreciate any help concerning this issue. Thanks much.

Good times!!

You need to change your knock sensor to one outta a 2001 and up 4.3l.

Thanks a million!!! I am swapping to the marine manifold and will replace the knock sensor then. I appreciate your help!

Good times!!

the one outta a 2001 is a 2 wire design and has a bolt that goes throught the middle of it I just got a 1/4 npt pipe plug and drilled and tapped it to accept a 1/4 20 to hold the new sensor down. Once you get to the sensor you will know what I am talking about. In efilive you can change what type of sensor it is but I think the values for the 327 trouble code are not available for use to modify via efilive, because even after I changed all the values I would still get that code, thats when I just swapped sensors.

What pins (pinouts) did you use on the '0411 for this KS? Thanks for your help!!

Good times!

I seem to remember 11 and 51 on the blue pcm connector, but let me confirm this once I get back to the truck

[overS10ded]

OK! I appreciate that info and will welcome your confirmation. Thanks again!

Good times!

Okay I got it,

PCM
Pin 9 is KS signal dark blue
Pin 49 is KS 5V Reference

On KS Connector
Pin A is KS Signal dark blue
Pin B is KS 5V Ref.


Hope this helps
