LOL! My car arrived with a Sanyo CD player, and the same thing happened.

I got my new head unit, wired it all up (correctly) and now it only goes up with radio.

Might want to check your wiring, the bodgy person who put the first one in ran the antenna wire to the head unit's remote wire. (used for switchin on amps) That made it go up each time.

omg lol wtf!

Ditch that head unit! What kind of HU doesn't have a power antenna wire??

My first ever headunit was a Kenwood, bought for $40 from Cash Converters... about 6 years ago, and it was already a few years old at the time. IT had a power antenna wire!

Did you install it yourself? Have you checked the wiring?

Make sure your remote wire is not touching anything (unless you run an amp, in which case it should only be connected to the amp remote wire)

I'm pretty sure that Pioneer wouldn't design it like that, and i'm very sure that R33's antenna's don't do this on their own.

I will re check everything. When you mean make sure the remote wire isnt touching anything, do u mean that is should be connected to the remote power antenna wire coming out of the head unit?

or should i wire it so the wire for the antenna coming out of the car goes to nothing.

Umm.. the remote wire FROM the HU:

If you have an amp, make sure it's connected to the amp's remote wire.

If you have no amp, that wire should be taped up and tidied so that it doesn't short on metal or anything. It should NOT be connected to your antenna wire (factory loom side).

The HU should have a "p.cont" or "antenna" or something wire... this is the one for the antenna. I'd be shocked if a modern HU DOESN'T have an antenna control wire.

I might have made that unclear...

HU "Remote" wire -> nothing

HU "Power Antenna" wire -> antenna power wire in the factory harness

ok so let me get this striaght. The wire that powers the antenna goes to nothing.

And then the actual antenna wire just plugs into the head unit as normal.

If that is the case i dont see how the antenna will power up at all???

What i have done for the mean time is just wired it to the switch next to the a/c unit.

I might leave it like this so i can control the antenna even when i have the radio on.

ok after reading it agian it makes sense. My bad

But that is how i have wired it but the antenna still comes up when playing a cd.

Ah ok.. and yeah, the wire that you referred to is not actually an antenna power wire, it's the remote wire for an amp.

The antenna itself is powered via wiring in the boot.

Very odd that this would happen. 100% sure that you haven't got the remote and the antenna wire switched around?

    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
