A New HICUP to stump the panel. RSX Injectors + boosted Civic + Missing Link=CEL....
Why? You might ask.........Lemme explain.
Opto pointed out this VERY obvious point that may have been overlooked. Here is a snippett of the convo him and I had:
D: "Yup RSX injectors are installed. And I used the injection correction factor on the e-manage too."
O: "What, like 240 to 340? How did it idle? I can't wait..."
D: "With Denso Iridium IK20's and the RSX injectors it actually idles fine. Not a problem. I think any larger it would have had a problem."
O: "Good to hear - that was a concern of mine. I don't think people understand how sensitive our ECU is to change. If you put too large of an injector in - you will throw a the "barometric sensor" error code (the ecu has a pressure sensor built into it - if the MAP sensor and the baro sensor are too far apart in measurements - it throws a code)..."
D: "You know what though. I did have a Map/Baro Sensor CEL that came on. All I did was erase the code, clean out the filter on the ML and voila! Done. BTW, my filter was crazy dirty on it. So I think that had to do with it."
O: "Yeah, sounds like your sensors weren't jivin'..."
Key: D=Dezod O=Opto
So now this Hiccup seems to be the last bit to overcome. Anyone have any ideas on this panel stumper?

Just did a quick search - there were two folks on here that had the error code - C2i0v0i1C, and johnnyblaze. I think C2i0v0i1C fixed it eventually however....Not sure how (his posts don't say). Might be best to PM him.

According to the guys at HT that specific error code shouldn't put the ECU into limp mode - not sure what it exactly it does on our cars (could be different than 2000 series civics, even though both are OBDII).
For those that don't know - the error code exists when the MAP voltage and Barometric pressure sensor voltage (located inside of the ECU - IE you can't get at it. As for what it does - it is supposed to compensate fuel trims for altitude changes) vary significantly. I don't know how far they need to be out of whack to throw the code - but the injector change feature MAY be causing it. It might be better to use the MAP voltage correction map in the emanage to control the MAP voltage vs the injector correction feature....that is a possible fix.
The comment that was made about running RC injectors - that still won't do squat. The injectors have nothing to do with it - its the MAP voltage that's causing the CEL.

ok I get the whole idea about the map/baro sensors. From what you say its from the correction feature in the emanage. I believe you are most likely right on that. What I'm not clear on is what the emange does to correct for bigger injectors. I also dont understand how the voltage would be allowed to change so greatly if we are using ML. In an N/A motor, pretty much assuming you will always have a lil vacuum no matter what, maybe when the map sees that there is no negative or positive pressure the computer says WTF is going on. The only thing I can picture in my head is that when the ecu senses no vaccuum(under boost)even with the ML blocking possive pressure readings it doesnt mix with the ecu because the voltage is just a lil to far out of whack. I am probably way off but maybe I can spark an idea in someone's head. I dont have a lot of good ones today
I have a similar problem but I'm not boosting.
I got the code after I changed the intake manifold.
When I erase the code it goes away then after I turn the car off and I started again it and drivre it will come back again as I'm driving but it wont afect performance.
I did noticed that my EVAP two way valve is not connected to anything.
Is it better just to change the computer all together for a universal unit?
Radder than trying to correct ours?

huh, all my intake manifolds never tripped the code, weird. I had the evap valve connected though.
Still wonder if changing the computer all togeteher could be a better route.
I'll be boosting soon and I'll like to know.

Dezod, have you tried running the injectors with the injector correction feature off? I know that C2o1 civic (whatever the sn is) has his running without codes so we should be pm'ing him i think.
