LOL the F/IC probably costs $100 total to manufacture, what a profit margin.

I'd be curious to see if that would work. From what I understand, per AEM, they use "the software" to calibrate the sensor. Would be an awesome post if it was able to be swapped. The only downside is not being able to send it to AEM if the hardware was tampered with.

Mine used to fluctuate a lot, so basically I did the same thing that Crush did, but went a step further with it...Right now I am bypassing both fittings, the one that routes inside the FIC and the "stepper" vacuum fitting that changes the diameter of the line inside. It goes like this now...

Basically just two lines with the vacuum filter in the middle. Got rid of all fluctuations that I had and it is way smoother when tuning.

To be honest, I really don't know why they skimped out on THAT sensor. It is the only thing to tune the damn thing off of, besides TPS...

Why not just add a harness and use a real MAP sensor. Or at least have that as a future upgrade. Ah well, enough ranting.

now thats doing it up hardcore style...good job...there is got to be a way to calibrate the software to the sensor unless the sensors are made with tight specs then may not be necessary.

Go HARD or go HOME!!!!

LOL...

It was very frustrating tuning it with that stupid onboard sensor, this basically fixed one of my big problems I had with the F/IC...

I'm pretty decent with solder Crush. Did my own LED swap no problem. I'll go pick up a solder-vac and bust out the grounded 25 watt pencil tip soldering iron and hope for the best!

Well, long story short, the new MAP sensor wasn't going to fix anything. The whole MAP sensor circuit is shot. Do you know how I know? Because when I pulled off the little vacuum line going into it, water came out... WTF?

The car ran perfectly whilst untouched and unchanged for over a year and then one day, no MAP reading. You would think it would slowly become less accurate or something but nope. So now, it's just a VTEC modifier lol. Everything else works perfect except the MAP circuit. If anyone is interested, let me know because I'll sell it for 100 bucks plus shipping to a Honda guy or something that wants to play with his VTEC tables or change the A/F since they have an onboard MAP that could be tied into one of the Aux inputs. I have everything that comes with a brand new one still in the box.

id say just try it out since you got the stuff to do it and just see what happens...if you screw up no harm no foul but if it works you just saved yourself some molla.
