Default 2.2 ecotech

ive got a 07 Ion which I bought with a rod knock. I gave my boss the VIN and asked him to order me a new crankshaft. I pulled the engine and installed the new crankshaft without checking it in detail, got everything back together and started it up. First start it kinda cranked long but thought nothing of it being i had the car apart for about a month. She ran great, no noises or anything. Shut it off and restarted. I thought it still had a kinda long crank but then realized i had to do a crankshaft relearn. I tried to do a relearn but found the ecm not picking up engine rpms on my scanner. I checked in other scan data that the rpms were working just fine and the tach was working. I was getting kinda confused. Looking into it more the pcm wasn't picking up the crank signal correctly so i just assumed i damaged the crank sensor while disassembly and reassembly. I installed a new sensor and had the same problem. So next night i decided i was going to check wiring thinking i damaged something when i pulled the engine. All that checked good. So I went over all my grounds, they also were fine. After doing a bunch of research I figured out the wrong crankshaft was ordered and installed. The crank i pulled out had a reluctor wheel with 58 teeth on it and the one i installed had the teeth built into the crankshaft lobe. Ive been told by the parts store that my engine is actually a 2.4... Im not believing that.

So i guess my question is, has anyone come across this and is there a way to program my PCM to look for the 05/06 crank and not the 07 crank reluctor wheel? Or am i going to have to pull the engine back apart and install the correct crankshaft? If i program it as a 05/06 is it going to mess with my ignition because i have 4 seperate coils and not the one coil pack/ignition module.

Thanks for any advise!
