Got the plug from spoolinup.com awhile back. It came with the wires and all you have to do is splice it in. Haven't had much time since the SEMA trip but I finally had a chance today.

Before I started, I had driven the car the other day and it was bucking like it normally does with a bad cam sensor. The car would fall flat on its face soon as it hit boost.

Without replacing the cam sensor, I cut off the old pigtail and soldered on the new one. I made it longer so the wires wouldn't have a sharp bend the old pigtail had. The extra slack in the wires can only help under vibration at high RPM. After soldering the wires, I used some heat shrink tubing and new black wire shielding. You can't even tell the pig tail has been replaced.

Took it for a spin expecting the car to fall in its face again assuming my cam sensor was still bad. To my surprise I hit full 40psi of boost and no issues! Car ran smooth and I was actually spinning all 4 tires in 2nd gear at one point! HELL YEAH! I think this might have fixed the issue.

Lost my first cam sensor Thanksgiving evening. Top of 4th was taking forever to wind out- way down on power, so I let out and it died. I coasted like 1/2 a mile to a Safeway parking lot, checked all the wires (DVM in glovebox too, old DSM owner habit) before I changed the sensor and couldn't find an issue. Replaced the sensor and it fired right up.

Well it seems i may have lost a sensor last night as well. Took the car out, all seemed well for maybe 10minutes. Then at high rpm's under WOT, it would start to "misfire", I thought it was wierd as i had just put in a fresh set of plugs. I continued to drive and it seemed to get worse. Headed back towards my house and the car died. I'll be checking my harness too.

Wow. This is crazy. I've never had this issue but it might not be an Evo IX thing

I been rockin the AEM V1 and stock cam sensor for 7 years. Never had 1 problem from it. No heat shield and tubular manifold most of its life. I think these failures are either heat for wiring related.

It could be related to the two cams sensor that the IX has.

Maybe any interruption can cause issues with AEM because the software doesn’t recover well. Since the IX has two cam sensors it could help??? Just throwing an idea out there??

Good point, it's exactly what the oem ecu, or as example the power fc do, it would be a great thing to have this option on aem.....

So my car hadn't ate a cam sensor since I cut a hole in the aluminum undertray where my wastegate dumps. Been chasing a misfire for months trying different coils and plugs, tried a new cam sensor a couple times, even tried swapping ecus. Then while logging yesterday noticed the rpms spiking weirdly in the logs, but not physically revving. i.e. logging a 4th gear pull, at full load around 5k rpms it would spike up to 10k for a millisecond. Checked the wiring again and found a small crack in the cam sensor plug. I still had the spoolinup.com pigtail but it looks like the crank sensor plug instead. Luckily Kevin from jackstransmissions.com had a 2gb harness we stole one from. Soldered it in last night and problem solved. Like rodent I left the old sensor installed and just cut the wires off the old plug and it runs flawlessly now.

I <3 Jacks.
