Hey guys,
I`m pretty sure the wiring harness wiring is slightly different on my JDM Type R DC5.

I have the AEM Series 2 ECU and flashed the Base K20A2 Tune.

However, the car starts and dies within 10 seconds.

I think it's not firing up the injectors or something? Not too sure.

Or am i suppose to change a pin on the harness for the AEM to work?

i have the same problem with you...someone told me that i have to change a wire on the harness to make the fuel pump work...this problem is because aem ems series2 is for acura rsx type-s and not for the jdm...to put it on jdm you have to do some changes on the harness but i don't know what...if anyone knows please give as an answer...

i dont know if you removed the timing cover, but if you did the crank trigger can be installed backwords.

I think i may just have found the solution

JDM Harness, the Fuel Pressure Sensor is on E10 plug for JDM DC5

Since AEM Was based on a TYPE S USDM. the ECU sends signal to the E1.

In other words. Repin the harness, change the E10 wire to E1 and it will be sweet

ok thanks, i will do this tommorow and tell you about the results...

Actually, i got my car working last night. You don't have to REPIN!

What i did was inside AEM Tuner, i changed the E1 Output of fuel pump. To the E10 output. I think it was under the Others cat, Set the E10 pin to Fuel pump. and the car started straight away.

I can send screenshots later if you like. This shoudl really help someone with a JDM DC5 and wants to run the AEM ECU

 

[dc5CY]

please send me some screenshots to see what to do

do i did it correct?? i tried it on aemtuner but i don't have the car now to do it on the ecu, so i will do it tomorrow..just tell me if i did it correct to be sure

 

[dc5CY]

ok i did this today and the car started THANKS A LOT!! now the ecu needs to be remapped on my car and will be ok

Hey man!
Sorry didn't get a notification you replied!

Heh! Good advise from another jdm owner eh?

Frickin badass... Exactly what i thought a $1500 ecu should be capable of doing. I mean they only have a pin in every single slot on every plug! lmao usdm ep3 JDM k20a Using JDM harness cause it's long enough and I'm not a moron 😀🙌😱😆👏👏 one thing left to solve whys my throttle geeking out in aem tuner?.. Thanks smart JDM Dudes 👍

As we don't talk about a DBW TB, when talking about AEM Tuner (= AEM Series 2) I assume it to be the TPS which makes your TB looking like to geek out. Did you test another one for comparison or does your TB stick in a certain position?

Yeah I believe you are right, flip the outer two wires? Can't this be done in aem tuner also? It was at 100% but tried to calibrate it in aemt, now it's kinda flickering in the 30s and 40s. No I left original jdm so far. Still have a3 if fried

Do you have a log or log picture of it? Just to understand better what you mean.

Here are two shots, I hope they better explain?
Or let me know what I should snap a pic of?
Thanks so much for the help!

Not exactly what I am looking for, but interesting setup. TPS minimum voltage is 4.88 and maximum 5.08 V. To make that functioning right the minimum should be somewhere at 0.45 V and the maximum around 4.5 V. Are you aware of the calibration process of the TPS in the AEM Tuner SW?
