Should I consider AEM FIC?

 

I wouldn’t. I tried and couldn’t get it to operate with the factory ap1 ECU in closed loop, too many hiccups. Eventually it fuel washed my motor, destroying it. There have been some better but mixed results with the ap2 ECU for some reason, maybe less sensitive to external inputs. Seems like Emanage is more sound, even though its old school tech. Finding a good tuner is the key. You would be much better off sticking to the factory comptech system up to 7psi. After that, go with a full EMS.

 

Here's what you need to do / know:

1. Verify that the blower unit is infact a Novi-1000. You will need a source a smaller pulley, the AP1 size tha came with that kit will not spin the blower fast enough for your lower redline. Science of speed is a good place to start based on how much boost you are looking to run. A 4.2" will give you approx 6-psi. They offer a variety of sizes for you to choose from but you will definitely want to go to a smaller pulley than what came with the AP1 kit to make the horsepower gains. $89

2. You will need a different drive pulley belt. $25 - $35

3. The air-box bracket. It is slightly different in the AP1 version vs the AP2, but can be purchased directly from CT-Engineering. Or you can make one of your own. The CT-Engineering one is $14

4. The Piggy-Back ECU with the AP1 kit needs to have the voltage output increased to 2.93 this can be done by putting it on a voltage meter that reads a constant DC voltage, and turning the small set-screw on the side of the piggy-back ECU until the metere reads 2.93

5. Under normal circumstances, the fuel pressure regulator would need to be recalibrated to output more fuel / higher volume, but if you have the K-Pro or AEM setup, you will not even be using the fuel pressure regulator as part of the system.

6. You will still need to purchase a High-Flow Fuel Pump. This can be purchased from CT-Engineering for $135 -or- there are other aftermarket ones available.

That's pretty much it.

 

Rob regarding the piggy back, this is an old Comptech kit, it doesn't come with one of the piggy back Fuel/Vtec controllers now offered in the CT-Engineering and SOS kits. Just the Electronic Signal Modifier for the MAP is used. Are you saying the ESM has to be recalibrated for an ap2? If so I wasn't aware of that. Not sure why it would.

Looks like from the pic it has a fuel pump included. Who knows if its Stock or high flow though.

 

I should have said ESM....and yes, I believe there is a voltage difference. The AP1 is where around 2.88 and it will need to be readjusted for the AP2 up to 2.93 or it will mess with the AP1 signal.

 

Thanks for clarifying, and good info right there. I didn’t realize the ap2 ecu changed in that regard, good to know its adjustable. I’m still using an ap1 ecu with my f22 so I guess that’s why I never encountered this potential issue. Go figure though, I’m running the stock system and MAP at 13psi and that doesn’t matter lol.

Didn’t Ray help design this ESM for Comptech back in the day?

 

Wow thanks so much for all of this information.

 

Gentlemen,

Will 4" Pulley really produce 7PSI on an AP2 F22 2004 S2000? I just made a purchase from one of the members who was on top of his game and shipped it as soon as I paid. Seems like a stand up guy. However... I got off the phone with CT-Egineering and they told me that the 4" Pulley sold to me is in fact a 9PSI pulley and not 7 and they offered to sell their 4.1" Pulley with the belt.

Since I am running stock injectors and 7psi is pushin it... I don't want to find out the hard way when all of a sudden I hit 9 PSI. Can a few of you confirm that 4" Pulley is in fact an actually a 7psi Pulley. IF not I guess time to contact Compteh again and buy their last 4.1"

 

According to charts here, 4" should make somewhere around 7psi on a 2.2L, if the blower is a Novi 1000. Still, HOW the pulley is measured matters, too.

Yes different brand pulleys are measures differently which makes it confusing. In my experience at sea level, the 4" SOS pulley will make exactly 7psi at 8k rpm. You should be fine with the stock set up. Just make sure to increase fuel pressure. Your likely only going have 2-4 threads showing above the lock nut on the fpr. Its going to run rich in the high 10's -low 11's under vtec to run proper afr above, this is ok, but you will gain some power/response leaning this area of the curve out 12.5/13afr with a vafc. Aim for 12-12.5afr above vtec and you will be golden.
