Map sensor issue on K24a2?

[davisj3537]

Well I installed a k24a2 into a base rsx and we are having problems with the idle. It runs exactly like if you were to tap the wrong map sensor location on a rbc for the 05-06 models. It is running the stock tsx manifold and currently I'm using the map location on the manifold. I tried switching it to the TB to check but it wont even start when plugged in there. Anybody have any ideas? Still using the base engine harness and already modified the tps sensor.

I also posted this on hondata but have gotten no response yet.

Check for vacuum leaks. Tighten IM TB TB adapter. Check brake booster hose and hose on the left side. Did you use a gasket on both sides of the adapter?

Not sure what you are saying the issue is, never heard of having to tap the RBC for the MAP sensor.

He's talking about using the port on the rbc instead of the TB, but it doesn't mater which one you use

My engine runs far smoother with the map sensor on the RBC mani. You can even see the difference in the MAP positions in Kpro and document it on datalogs very quickly and easily. The TB position creates a much larger fluctuation in the MAP reading.

It is not acting like vaccum leak. The idle dips bad and dies. I used two gaskets. I checked it all man.

Exactly....on the 05-06 rsx's you have to use the port on the rbc or it runs with a super low idle and dies like the car is doing now.

The car could die like that with a vac leak, do the rpms bounce at all?

It could be in the tune

[talonXracer]

What is the MAP reading while at idle? In Mbar

The idle is set at 1000 in kpro and it sets at a steady 500rpms and dies completely if it is warmed up.

I wont be able to check that till this coming weekend...but that is a good idea. I never really looked at it

[davisj3537]

Once awhile back on a different car I didn't drill the hole in the IMG when installing a rbc and it ran like this. But I never unbolted the tsx manifold...it would have been bolted up right since it ran good in the tsx before it got pulled. I checked and double checked the vaccum lines. I have two map sensors and tried them both in both locations

[talonXracer]

MAP and TPS connectors are not switched around are they? Is the IAC operating correctly? Connector OK?

[talonXracer]

All drilling the IMG does is allow the AAV to operate. And I havnt installed or used a AAV in over 4 years. Could the IMG's PRB spec hole be partially exposed?

See if you feel any vacuum with your fingers over the IAC hole. Do you have another TB to try?

that happen to me when i did my tsx swap. i pluged them in backwards an the car would not run unless i was pressing the gas. it was also dumping alot of gas. i also messed up my map sensor. but once i switched them back car ran great. i miss my swap

you said it runs fine if u have it connected to the manifold but not by the throttle body why not just have it connected on the manifold.
