New bad PCM. I believe they have to do an install/update/info install. On the new PCM.
Pushed back pins on the connector to the PCM. Wire harness damage/break.

 

They just called back. Turns out one of the fuses I tapped was not for the interior lights...which i thought it was....turns out it was for the immobilizer. Needless to say that caused the new PCM to **** a brick.

I'll get the car in a hour. Thank God.

 

Good news.

 

hooray!

Got the car back...but the stock map does not like my AP pulley. So it stalls while idling...

Now I tried to put my MM map back on it...but my AP just gave me a fatal error. This is getting terrible.

Anyone know what I should do from here. Everyone seems to just send their AP's back to Cobb, but i got mine 2nd hand.

 

id swap the stock pulley back on and make sure everything's kosher before looking at other things, just in case. unless the issue with your pulley is known, im not into the rx8 aftermarket much

Try this..............turn the car on but do not start it. Tap the brake pedal 20 or 30 times real fast until you see the oil needle sweep to the right and then back to the left, then turn the car off.

Then start it and see what happens, go for a little drive, and don't shut it off cold.

If your needle doesn't sweep when you do the brake tap, then turn the car off for a few seconds and try it again.

This reset the E-shaft profile and is common that this needs to be done after installing that pulley. Maybe when they reset the PCM it set it all the way back???????

 

I'll try that if it stalls again. It has not done it. It did it once for the first 2 drive cycles. It didn't do it on my 3rd drive cycle. I think its learning lol.

 

it will take 4 to 5 drive cycles before the ecu is good at controlling the idle.. give it time. and if it is a 04 dont forget to reset the ac amp. that will smooth things down a bit.

thx swoope, it is a 04. Which amp is for the AC?

Thx again swoope!

Good news, im pretty confident that my ECU has adjusted for the AP Pulley and all. This morning, my car didn't hunt for idle at all. Which makes me a happy panda.

 

3000 mi later, IT HAPPENED AGAIN! I checked all fuses, none burned. I reset the ECU cables, nothing. And I reconnected the battery terminals...nothing.

Tow truck is on its way...again

 

The dealership replaced my RKE module.

Car worked great for a week.

Yesterday it happened again. They still don't know what is wrong with it...

 

now theyre just throwing darts.

What has to happen for the "Lemon Law" to apply?

 

I know, and its frigging annoying.

You have to have the exact same thing break four times in one month.

 

I found the codes that were illumiated. I read these from my AP:

PCM U0073
PCM U0121
PCM U0155

IC U1900
IC U2516

EPS U1900
EPS U0073

RKE U1900

TPMS U1900
TPMS U2516

I know U0073 is a CAN communication error...which isn't good...

I'm thinking it has something to do with some harness coming loose or fraying.

 

Hey francesco sorry to hear about the car, any updates yet??

 

Thx Oscar, no updates yet. They were supposed to have the new ABS module in today...but I haven't heard anything. I just found all of the shop manuals so I might try and see wtf is going on myself.

 

Wiring harness or bad ground.

 

Thx Jeff, I'll take some time this weekend to break out my multimeter and check the grounds out.

I still feel that it is a wiring harness that is bad. Because it has only happened like 1% of the time i drive the car. But I am running the car hard when it goes...

 

The multimeter probably won't catch it.
Its something intermittent.

 

Bah, well so far i have a new ECU. RKE Module, and soon a new ABS module.

 

Alright got the car back, new ABS module and fresh brake fluid. We'll see how long this lasts.
