Anyone having issues with O2 Sensor where its bouncing off crazy numbers on idle with E85. We added E85 last night and on pump, the idle was 14.1-14.7 range and after we added timing and fuel to compensate for the E85 and idle was super smooth but the AFR was all over the place, the analog gauge was...

I use to have somewhat of a same issue but after lowing my frequency range and raising the stepper motor, it's not doing as much but it still does it here and there. sometimes when i put in the clutch pedal and let go ( not in gear) rpm bounce a little for 3 seconds from 700-1500. It's weird. I need...

Thanks Zach, We lowered my Frequency range and raised my stepper motor higher and it helped with my weird idle bounce at 1st gear roll off, but it seems to act up still, here and there when it's warmed up, I'm guessing the Table will need adjustment and well as the After start "RPM". I will have to ...

for Idle motor setup. there is a frequency setup and would like to know what the frequency should be and how is that determined and what the stepper steps range should be and how is that determined. For Example, for the TPS, there is screen where it tells me what the % is at "Zero" throttle and what...

Can someone explain to me what the frequency ranges should be on the 2JZGTE Single Turbo motor should be?

How is the frequency determined?

Thanks

frequency 100hz
stepper steps rage 150 .... or 100 I don't remember

Issue is fixed from a help of a friend

Kisielisodd you were on the right track about the frequency and Stepper Range, those numbers needed to be adjusted and fixed the issue.

Hello Is there an issue with EMU and Idle Air Control on the 2JZGTE? we have been having some issues where the 2JZ is idle hunting and have trouble starting at start up. Also have some RPM drops and acting up when coming off from first gear under 1500. Was wondering if there are some known issues o...

I will try to post logs and screen shots of settings I have in the system.

Thanks

Wiring is not an issue for the IAC,

Just need to know what the settings should be?

My car would bounce RPMs and I can hear my IAC turn off and turn on and i m rolling off First gear

hey Korn, See below The way I have my relay wired up 87 - 12V constant connected to the Battery with a Fuse by the Battery. 85 - 12V Switched at Ignition, (mine is wired to my HKS Timer, Power Wire) 30 - Ground Wire - Connected to my EMU, Connected to Pin #5 on the Grey plug, See chart below 86 - Co...

Hey OP I posted a reply on Supraforums for you. You only need to run one ground wire from the relay, and that's directly to the EMU. You should have gotten a Chart from EMU with your ECU and they should have told you where to wire in the fuel pump. If they didn't, I will look at it when I get home. ...

haha.. even though your problem didnt actually exist sometimes it can exist!! I had a car once that when you turn on the thermo fan with the engine stopped the rpm would start and even injectors sometimes tick because the crank sensor was mounted on the front of the engine close to the fan motor an...

Do you know if there will be a software version for MAC in the near future? Microsoft Laptop I have got a virus and hate dealing with PC stuff since they are a lot slower and tend to break more often.

Just curious.

Hey Jadzwin Disregard my post, I clearly can't read. The whole time, I was reading my log incorrectly and I thought I had RPMs showing on ON position but wasn't. It was my MAP sensor reading….. I m so dumb but anyways here is a video of my car running, Enjoy! https://www.youtube.com/watch?v=lnxkwAi7...

Hey Jadzwin, I already have a Resistor on the car, I have a 2JZGTE swap with a resistor.

Is this the values or something I would input in the computer ?

Hello, Was wondering if anyone has had this issue. I m reading RPM when my key is ON position. This happen to me about a year ago and I grounded one one of the wire and the RPMs were gone but now its happening again and I havent touched anything. However, I m curious if one of the wiring are switche...

Hi! We have startup map for 1JZ/2JZ engines so it will help to start your engine. If you have any issuse just wrtie here we will help you for sure. However there should be no problems. The software works only under Microsoft Windows. Hello Jadzwin Where Can I be able to find the start up maps ? Tha...

Hello Everyone, I bought my EMU almost a year ago and was able to get my car started. At the time of the start up, I didn't have my Intercooler kit installed and revs were all over the place. Everytime I tapped the gas pedal, the Rmp would drop and then rise. It was being weird and I know I need a t...
