Do I Need a CASE Learn?
You DO need to perform the Crankshaft Variation Learn procedure if you physically install a new PCM, replace the crankshaft, camshaft, timing chain, crankshaft position sensor or balancer.

You DO NOT need to perform the Crankshaft Variation Learn procedure if you have new code flashed into your current PCM.


The crankshaft position system variation learning feature calculates the reference period errors that are caused by slight tolerance variations in the crankshaft, the crankshaft balancer interrupter rings, and the crankshaft position sensor hall effect switches. The calculated error allows the PCM to accurately compensate for reference period variations. This enhances the ability of the PCM to detect misfire events during a wider range of engine speed and load conditions.

The crankshaft position system variation values are stored in the PCM non-volatile memory after a learn procedure has been performed. If the crankshaft position system variation values are not stored in the PCM, DTC P1336 will set. The learn procedure is required after the following service procedures have been performed:

PCM replacement
Engine replacement
Crankshaft replacement
Crankshaft balancer replacement
Crankshaft position sensor replacement
Any engine repair which disturbs the crankshaft or the harmonic balancer to crankshaft position sensor relationship.


97's don't need a case learn with a PCM swap, just swap the Knock Modules and you're all set.

Service Manuals for 1997 GTP

The crankshaft position system variation compensating values are stored in the PCM non-volatile memory after a learn procedure has been performed. If the actual crankshaft position variation is no within the crankshaft position system variation compensating values stored in the PCM, DTC P0300 may set (refer to Diagnostic Aids for DTC P0300).

The crankshaft position system variation learn procedure must be performed when replacing the PCM to clear DTC P1336. The crankshaft position system variation learn procedure is also required when the following service procedures have been performed, regardless of whether or not DTC P1336 is set:


PCM replacement.
Engine replacement.
Crankshaft replacement.
Crankshaft balancer replacement.
Crankshaft position sensor replacement.
Any engine repair(s) which disturbs crankshaft/harmonic balancer to crankshaft position sensor relationship

I have the prj LL cam it has a real nice lobe and its very vavletrain friendly and built for stock heads contact sales@prjperfomance.com he can answer some of your questions I have a link to my exhaust clip in my sig

how much did u pay for it?

FWIW, when I did my cam install...IF you do; do everything at once. I went with the Comp Cams XP Cam, got the #105's and retainers. Had it installed curtousey of Green Bastard Products.

In the long run, it all depends on how far you are gonna mod. If you don't want to really "break" into the motor...I say rockers and headers...that'll be pretty quick too IMO

when i mod my car im going to buy everything at once and do it at once. hey bluegtp how does that port and polish thing work?

Step One...Take off Blower/Other Misc. Parts

Step Two...Ship to Green Bastard Products

Step Three...Wait Until it gets shipped back and then enjoy!!!

lol sounds easy enuff

Think I am kidding...it was that simple...good thing I live close to the company
