    Pic's and screenshots of AEM F/IC

    Folks, I've finalized the installation of the AEM Fuel and Ignition Controller on my RXP. I built a waterproof enclosure with flange-mount sealed connectors. The harness is totally plug-n-play, with NO splices into the stock harness.

    I've posted this info before, but it's worth saying again that I can control fuel based on rpm and boost. The F/IC has an on-board MAP sensor that reads up to 25 psi boost and can adjust fuel at any boost or rpm. You can even change the rpm and boost scales you tune in. For instance, you tune in 50 rpm increments around 8100 rpm and 1000 rpm increments around 3000 rpm if you want.

    On mine, I cut fuel across the board by 40% and it started up easy and ran fine with 62# injectors on the stock ECM. This device can also retard ignition timing, modify signals to the stock ECM (clamp MAP voltage, for instance), and log data including wideband. It has 2 outputs for 12 volt rpm or boost activated switches. Not that it helps us, but you can tune real-time. I've already got some funny looks on the river sitting or idling with a laptop on my lap.

    Not too bad for about $450 total invested (plus injectors), including wiring and connectors!

    I'll post more pic's later of it installed in the ski. If I ever get my prop straight (well, bent, actually), then I'll start cranking up the boost and post results.

    What makes this different from the Rude controller offered already?

    Does it do more than that piece?

    I thought long and hard about microsquirt (waterproof) before opting for the F/IC. The challenges are the gauges (they are run by the OEM ECU), security (DESS), idle control, the ignition pickup (I think you'd have to knock a tooth off the reluctor wheel), ignition coil info, and getting a good base map (does anyone even know how much timing these things run?).

    With the F/IC, most of these issues take care of themselves (well, taken care of by the stock ECU) and the base map is the stock one.

    Yes, the F/IC does alot more than the Rude controller. I'd like to expand on that, but it's getting pretty close to biting the hand that feeds us.

    Thanks for the consideration Mike. I have already looked in too the AEM Fuel control unit.

    It looks like a great part. It is better in alot of ways. Nothing like the F/IC was available when I built my control unit.

    My controller dose have its limitations. It is limited to injector sizing.

    I will not get into to much detail. It has done everything I have needed it to.

    Good luck with the AEM stuff.

    I've been able to run up to 13-14 psi boost so far without going lean, which really isn't a surprise. I'm really struggling with a prop/nozzle to get 80+ mph at 8100 rpm, though. It's weird having basically unlimited power available, but unable to use it since I can't seem to keep the rev's down.
