^^^If you need a harness made, this is the guy to talk to right here^^^^
He made a few of mine when I didnt feel like messing with it. He does very good, clean work, knows his stuff, and is more than fair with his prices. He has done a bunch of 3.5L, and a 3.7L stroker motors on "the other board". He has also developed the same thing I am doing but using an older M90 supercharger. He fabbed the entire kit from scratch. Look him up if you need something done.

I've seen a bunch of his projects online and he most definitely has some serious skills...!

A standalone ECU is always an option on anything. You just have to set up the system properly.

I am more than likely going to stick with the AEM FIC-6. I have really poured myself into understanding how the FIC works and talked to many people about it and found out that my tuner did not really know how to set it up. I will set it up correctly without the Comptech ESM and see what happens. I have about two more weeks of R&D left to do before I can say anything concrete. EMBlue is still not off the table.

update,
I have been hearing a sound coming from the motor at 6-7K RPM with the blower that I thought was knock. It is the same noise I had when I had the MP62 on the car with the 4-5 psi alternator pulley near the end of the 30,000 miles I had it on for. There was no noise when I first installed the blower. It almost sounds like an intermittent sparking sound that is loud and can easily be heard inside the car only at WOT. It happens about 5-10 times with each pull through a gear at the 6-7K RPM in any gear.
I removed the blower, put the stock injectors back in, reinstalled the stock crank pulley, and removed the AEM FIC-6 and the noise is still there now. I am going to remove the accessory belts and then run it through the gears to see if it is an accessory related bearing. If the noise goes away then great, I know it is accessory related. If it doesn’t go away then I know it is one of the pulleys on the timing belt or the main bearings/crank bearings are toast, or there is a problem on the top side of the motor.
Most of you don’t know but I was a tester for a new set of race cams for our car but they failed miserably to make ANY power, 150WHP max! I put the stockers back in, adjusted the valves and the power came right back. That was long after the noise started with the old blower and I currently have perfect compression, 240-250psi on all pistons. If the motor ends up being the culprit I will get a new one week after next and swap it in and go from there.
With the stock crank pulley installed I got back all the timing the ECU was pulling and am now getting the full 28+ degrees advance from the ECM at WOT. I have also notice that the hotter it is outside the less timing advance the ECM will run. At 79 degrees outside I saw 28+ degrees of advance and when it got up to 93 degrees outside today the advance dropped down to 26 max advance. Since it was 103 outside when the car was only showing 22 degrees max advance I am wondering if it was just temperature related. I think the UR crank pulley had something to do with it but I am not sure. I will know for sure if I end up having to pull the motor when I inspect the rod and crank bearings. Whatever the noise is I am also wondering if the stock knock sensor is thinking it is knock and pulling timing but since it is not now and the noise is still there, who knows?
I think I have figured out why the AEM was causing so much of a problem with the MAP sensor and know how to fix it. It was just a tuning issue, setting up the AEM FIC correctly. I now know how to work the damn thing and tune it myself. I just have to eliminate this noise before I can move forward with the blower project. To 3.5L or not, oh the decisions?
I will be out of town for a week so I won’t give an update until I get back and can turn some more wrenches. Jim

tt, we need results. FIC just aint cutting it Jim?!
To be honest, we've already gotten to the point where we can use the Emanage to tune and make a supple amount of power. Most guys aren't even gonna buy the FIC and to cut to the chase, the only ones that are even seriously considering this upgrade are the ones that already have the emanage hooked up [& already tuned] and ready to proceed. I just don't see how the FIC will yield any potential "benefits". I mean it has about the same /or similar qualities as the Emanage.

I am pretty sure I have the FIC cracked. The FIC is a better unit and I understand why you think it won’t do much that the Blue hasn’t done already. Even Shad Huntley, who co-developed the Comptech kit, agrees that the FIC is better and is the way to go. I speak with him on the phone sometimes.
I traced the noise back to the alternator bearings. It was the passenger bearing on the alternator. I have a new one on the way and will install it tomorrow when it arrives. If the problem is gone I will start work on the blower again immediately.

I just moved into a new house and am changing careers. I have not even driven the CLS in three weeks. I will get back on it shortly. I still have everything…just need the time to put it all together properly.
I just read the entire thread, figuring there was an amazing conclusion, it was like reading a book, turning the page and finding the remaining pages gone!
Amazing work, now I really want to know how it turned out!
