Im the guinea and did the AEM FIC today on a 03! So far lets see, installation was total cake with the help of a boomslang harness, just plug and play. For physical installation I left the FPR and CT ESM on and tuning was done by church.

Im CTSC /w AC stock boost and all components are stock! I still put down 324 rwhp according to the dynapack at Church Auto.

It is the 1910 model because no one or even AEM has any 1912 models available and ETA is undetermined, so i got a 1910 and sent it back to AEM for the hardware modification so that it will work with a 03.

As for the actual FIC itself, its sitting behind the drivers seat for now because Im not sure where to put it....

As for tuning, it went smooth, didnt throw any codes and the AFRs got ltuned out nicely; the car is now running very safely. Power curve and band are much smoother now and it feels alittle stronger down low because we leaned it out from the pig rich state it previously was in.

So all in all, so far, this piggy is doing its job well and I will be adding some 650cc and a 8lb pulley later. Im not sure how to tell if it detunes itself, but ill keep an eye on it and it will be back at church when im ready to upgrade.

Since it seems im the first to do this, or atleast report on it, others feel free to take the dive because I dont see any negative sides to it yet.

Shawn Church will tune in here soon to add his observations and any technical notes that I am not familiar with.

 

Nice guinea pig . Excellent , keep us informed ! I may very well go this route .

 

I was in favor of the E-Manage ultimate due to the popularity of the unit in this forum but later on did more research and now I am also interested in the AEM F/I C unit. Why didn't you remove the ESM and FPR, are they even needed after the 650cc's and the F/I C?

 

I was told it was ok to leave the ESM and FPR on while still using stock injectors, but when I go with larger injectors, the FPR and ESM will need to be removed.

 

Hmm im not sure about that part, but Church should be tuning in soon to add his comments, thats a good question for him.

 

Hey all,

The ESM was left in place for simplicity. It performs the same function as the FIC's MAP clamp so it is redundant. The FIC, when properly used, reads boost from its own map sensor, so the factory sensor is not in play when it comes to the fueling curve on the FIC.

Much like any new product, the FIC is gradually beginning to realize its true potential. While I will always prefer full engine management control, it is nice that S2K owners have multiple piggyback offerings out there to choose from.

The one thing that we did find interesting is that at part throttle, despite running the stock injectors, we had to add fuel on the FIC to avoid a lean stumble condition. This should not have been the case as the stock ECU should have been more than capable of handling that (as it does with the ESM normally). We have occasionally seen this on other FIC cars of different makes (but not always), so it may be a matter of some signal voltages being slightly altered even when we're not asking for anything (harness issues, wire length, noise? Who knows....). We'll see whether Kyushin's car has any other tricks up its sleeve down the road.

Ok some slight problems have arisen seems from the FIC and the AEM FPR, I keep getting CELs which read system running too rich, sometimes idle is alittle eratic and the 4krpm hesitation comes and goes. Ill get it back to church when i can for further tuning.

 

any updates?
i just got a modified 1910 model for N/A tuning.

 

why use it for a na setup? it can only retard timing, not add any.

 

updates! i took it to autowave for further inspection and it seems i had some fuel delivery problems with pressure instability and we found my fuel filter sock was clogged with crap and pressure was eratic. we replaced to fuel pump and retuned and all is well, i couldnt be more happy with the FIC
