    Keith, I think so unfortunately. I dont have access to any of the cars you guys are talking about, Im just dumping the information Ive learned over the years. If the P12 works with your BCM, then the last thing will be to figure out what to do with the P12s exhaust cam VVT settings. Your motor wont have the sensor or ability to control it, maybe do some digging in the PCM to see if we can shut it off.

    Ok not a problem if it doesnt work. I dont think its real expensive to do this swap and if it does not work oh well. I will have learned some stuff.

    To touch a 4Cyl PCM I believe you need a V2. For a P12 you have to have a V2 as it communicates via CAN which V1 cant communicate on.

    ive got some info. apparently I can flash a Ld9 s/c tune to my s10 pcm. The ld9 shares the same 7x reluctor as my pcm. Im not sure if this reflash installs just the fuel and spark tables or the whole operating system from the ld9?? The same person told me if this flash does take on my s10(he is not 100% positive it will) that I might lose my gauge functions like the 99 earlier cavaliers do, conflict with the bcm. On 2000 and later cavaliers the reflash works and you dont lose gauge functions. So it works on cavaliers but nobody is sure if it will work on a s10, and who knows if the bcm will function with the new reflash. Anyway if it worked I would have 2 bar tuning. I guess only one way to find out. Anyone have any input on this? Thanks keith

    new info. I just read that the ld9 s/c reflash will just change like one table in my pcm. Instead of the V/E table read as TPS it will read in KPA for the map. That is the only table its supposed to change. So it changes fueling from alpha-n to speed density.

    Then you could split the table using a 2Bar MAP and be good, albeit with lower table resolution. Try it out!

    Were you able to get your hands on a LD9 file? If you don't mind, please post it.
