Be aware that at WOT, your fueling is no longer determined by LTFT numbers, but by the reading from your O2 sensor. I think the LTFT locks in at whatever value it has been using for part throttle, then the PCM uses O2 data for fueling on WOT runs. That'* about all I know about it.

Bob, did you swap your old knock module over from your old PCM when you installed this new one? I seem to remember you did, but I need to ask. If you didn't, I would suggest a CASE learn as your first order of business. Even if you did, I would still suggest a CASE learn because it'* easy to do. I know there'* a simple procedure for doing it, but many dealerships are unfamiliar with someone simply walking in and asking for a CASE procedure. I'll try to find the link for the procedure so you can print it out and take it to a dealership for them to try. Many dealers will do it for free because of the simplicity of the procedure.

Thanks! Yeah, I remember that'* how LTFT'* work now that you remind me. And yes, I did swap modules over between PCM'*. I'm a little leery of my rinky dink dealer in P-ville here, but I'll make damn sure they don't reflash my Intense burn.

Here ya go! CASE Learn Procedure Instructions

EDIT: Of course, ignore the part about entering 1998 as the year since you have a '97

Awesome! Why does it say "make sure they enter 1998 as the year?" Is that just an example?
What'* the story on LT4 modules too?
Thanks again.

See my edit about the 1998 year. It'* just an example.

You'll have to wait for Jeremiah to comment on the LT4 module, as I have no experience with them.

I wonder if there is any chance that Intense programmed too much timing into your PCM when they flashed it. Perhaps you should use your Aeroforce to read your timing numbers at the throttle settings where the KR spikes up. I don't know if I'll be able to interpret them properly, but I'm sure Jeremiah, Todd, or Scott Cook could browse this thread and help you out. Maybe we'll even get Foghorn to poke his head in here.

Here'* the thread I had asking about my timing numbers. (this was only a moderate acceleration from a stop, not WOT)

I know the '97 displays as negative, but both PCM'* seemed to display similarly, so I don't think the Intense one has anything to do with it.

Ok, I looked at timing numbers a lot more closely today. At WOT I'm 23* - This is the Intense PCM with added timing selected. If I get out of those lower rpms quickly - as in a roll from about 10mph I see NO KR. I'm still seeing a little KR at the bottom of 2nd though.
On the highway with cruise on and going 70, my timing is 37* - as soon as I get KR it drops into the upper 20'* and see about 6* KR.
(Basically, I'd like to say the sum of the KR and the current timing roughly equals what timing is supposed to be - but that'* the way things work I assume )

I would recommend a CASE learn.

Definitely try the CASE procedure first, Bob. Your WOT timing is where it should be. I'm not sure about the part throttle numbers, but they're probably good. Get the easy things out of the way first, and then try the harder stuff. Hopefully Jeremiah comes back and elaborates on the knock sensor he mentioned.

I wouldn't worry about driving the car right now. I have to assume the KR is false, and is merely your PCM trying to limit the low-end torque going through your tranny. You won't hurt anything by driving it.

I would have to think it'* false too. This same thing happens with the stock PCM so this is nothing new. For I know the car did this its entire life and I only found out now due to a scanner CASE learn will be the first step though...thanks!
