Hello
I'm after feedback on the AEM FIC & 91-94 OEM ECU with a low boost turbo setup. approx. 400hp
I understand there's not too much adjustment.
So is there a max injector size I can run before I run out of adjustment of nice idle & cruise & full load.
any advice appreciated.
My car is a 1998 NSX and it is still a OBD-1 car because for some reasons Honda did not introduce OBD2 until 2000 in Europe.
I have added a AEM FIC after I blew my first engine with the standard Comptech box on my low-boost CTSC.
Even though I had expected the Comptech to be as reliable as every one said, it still did not work out for me, so I am much more careful now.
Together with the AEM FIC I have added the 550CC injectors from SOS to make sure I will always have enough fuel, whatever the RPM. I also added a IAT, boost and AFR sensor.
So far, the car has been reliable. My tune is very conservative with much enrichment and much retardation under boost. I'd rather sacrifice some HP for the sake of less chance of sacrificing another engine (the 3.2 is hard to come by).
For a time, I had some trouble with throttle response at low RPM's. I went back to the tuner and he changed the mappings (driving him around and he looking at the fuel maps). Once he changed that, it has been running fine.
The car might not be as fast as with the previous (non-FIC) setup, but I feel a lot safer now.
The main reason I chose the FIC was that a full engine management system was at that time not advised. Not because it would not work, but because a full after-market AEM setup is only as good as the tuner setting it up.
Since there a very few NSX's where I live, I did not want to take any more chances than I had to.
