So, I read that a special circuit is involved with your PnP harness for the FIC to understand and modify the MAF. I know this is a 4G Eclipse forum, but I have a Lancer Ralliart 4G69. The ECU plugs are not the same for both (I believe), so I don't think that harness would work for me and I ask:
I have a damaged Lancer Ralliart 4G69 ECU laying around. If I read correctly, you're the creator of that PnP harness(or the one who distributes them, I don't know). What if I mailed you that ECU? Would you be able to replicate that PnP with the circuitry to modify MAF for my ECU? I can provide the ECU pinouts info for it, as well as a pic of the plugs. If this is possible, where could I buy it? I'm searching for "BilletRacing", but I'm not sure what I'm looking for... Since I would be sending an ECU, my 4G69 could be the guinea pig for this harness...
I'm not looking for the timing advance option just yet since I see that your fuel is being modified via the injector harness. It's nice, but I want to do this bit by bit. I just want to be able to modify the MAF signal, and maybe O2 sensors, using the FIC 6 for now.
Let's say the harness can't be done... Would I be able to use the circuitry for the MAF by just using what I need from your harness? Meaning, using your harness without the plugs to properly connect the MAF to the FIC.
Sorry to ask this much... Like I've read a lot here through other threads, evolutionm.net does have a lot info on the engine, but it's the modifying or electronics that they don't say too much about because of "secrecy" between the people who know, and ignorance from others(like me).
Let me know...

Got any high res pics of the connectors that plug into the ECU? That would tell me the most about whether or not I can do a PnP.

As for the MAF sensor...is it the same sensor as the 4G? If so, then yes, I can interface it. If it's a frequency based sensor (karman vortex) then you'll need the FIC8 as it's the only one with karman based compatibility...
