I did the AP1 to AP2 harness conversion for emanage ultimate (I have a non-DBW AP2), but for some reason I'm getting cel codes: p122 and p1121 which both have to do with the TPS and voltage. The car stumbles and loses throttle (to the point where I'm pressing the pedal down and getting absolutely no revs) but it will only do that sometimes right after I start the car and try to drive. After about a minute or two the problem mysteriously corrects itself and the car runs strong with no issues.

I didn't have these cel's prior to installing emanage, so I'm assuming it has something to do with that and the conversion. I followed this diagram:


What else could it be? I don't want these codes, and I don't want the fear that my car is going to leave me stranded.

 

Hi I'm back!
I asked about having oil leak in my car long time ago.
Been busy modifying other parts thean fixing the turbo but now I have alot of blue smoke coming out everytime I stay still.
While driving its all fine but whenever I stop for over a minute my car would become a nuclear factory.
Can anyone point out a good rebuildshop that can take the turbo off and rebuild too? (Anywhere socal)
And also good tuner in socal if you know. I've seen reviews for church and bisimoto but that's about it.
Thanks in advance

 

where did u buy new at?

 

I heard the same thing. I have a Hondadata engine management unit. It works well. I think that many people have cracked exhaust manifolds from the Greddy kit.

 

I ordered the kit new from Greddy n I even sold the emanage n got a aem version 2 to make the tuners life easier n no one still doesn't wanna tune my car . N I'm gonna order a pfab manifold to prevent cracking.

 

Finally installed the pfab (great product/service btw) greddy replacement after cracking TWO greddy cast iron manifolds. Feels great, but I noticed boost creep (up to 12psi and let off) last night. It was kinda cold too. I have the t1r 70mm dual exhaust and a test pipe. What can I do to prevent this boost creep?

 

That's Wierd? Any tuner should be able to tune any set up on aem ems

 

Port the wastegate

 

will this completely solve the problem? or is this also a tuning issue?

 

From all the reading iv done yes it will completly solve it. And I would a assume a tune would be of your bestt interest when changing anything on your set up. But I have read the DIY its out there somewhere it doesn't seem to hard at all you can do it your self. It would just take some time.

I would think you can port it and be fine without a tune. Somone plz chime in and correct me if I'm wrong, I to am looking.into getting my wastegate ported
