i've tried loading the file so far its slightly better. About the AC idle side it still misfire when its turn on. AFR is around 13.5-14.
Coils ad new plugs has been replaced but same issue occurs.

I see in the log file the lambda goes quite lean at around 2500RPM, but it is hard to tell if it is going lean because there is a misfire, or if the lean mixture is the cause of the misfire. You will have to try richening it up in that area to see if it improves or not.
I have made some idle adjustment to your map and set the fuel pump speed control to switch to medium speed earlier in case that is the cause of the lean condition. Idle likely still wont be great but hopefully getting closer.
thanks adam will try this out and update.

ok ive setup the map and config all the required settings. i still have issue with misfiring when revving & also when AC was turn on its stumble and idle not right. attached new logs and map.

Idle control is not active because your MAP is above the MAP lockout. Cant tell much about the fuel tune with no lambda so there may be other issues, but start by getting idle control set up. I would enable idle ignition control, use the idle ign settings below and fill out a suitable idle target RPM table. Then tune the base position table so that idle ign timing bounces around somewhere close to the ignition idle target during normal idle conditions.
You've got no accel fuel since the cold correction table is zeroed out and you have warm-up enrichment adding fuel even when warm so likely the fuel tune needs a lot of work before idle will be good. VVT needs to be calibrated before it will function.
ive done a relog one with AC on and one without can you help me check thanks. is the ethrottle correct after i did a calibration.

hi can someone have a look at my log. i cant seem to get my idle to stable down.

Attach your tune and dash config.
here's the setup

Upload the log file as well.
But what sensor and controller are you using and how is it connected to the ECU?
Also where in the exhaust is it fitted?here's my log.
im using AEM UEGO which is wired to the CAN in the ECU.
Fitted just at the downpipe

hi guys would like to ask if someone can have a look at my log and why my afr isnt smooth? i've tried adjusting its still the same.

You'll need a variable resistance level sender (like most OEM sensors), a 5v supply, and the signal from the sender with a pullup-resistor to 5v (usually much lower than most temp sensor pullups) on it feeding into an analog input on the ecu. It should be possible to set up a custom stream to send this information to the CD7 dash once you're reading it and have it calbrated in the ecu.
I've done with wiring but im not sure how to setup the can setup in the AEM software.

Have you purchased the AEM injection kit already? Because unless you want the physical buttons on the controller to change your settings - all the functions of that unit could be controlled directly by the ECU.
Yes I have the whole kit with the controller. How do I set it up to the ecu to control the kit?

22 hours ago, koracing said:Page 5 shows two wires going toward the top of the page - a yellow +12v Arm and a green boost safe wire that is listed as a low side output when there is a problem. I would wire the boost safe output from the controller to a spare DI input on the ecu. I would also set up a relay to power the system via the ARM + via a relay controlled by the link as well. Then you can use a combination of an arming switch in the cabin plus logic from the link before the system would be active.
Is there a simpler way to let the ECU control when the methanol start doing its work.

What is a AEM methanol unit?

hello i also need help setting up the AEM CD7 dash for fuel level link to the ecu. what setup can i use ?
thanks
-
hi i need help wiring the aem methanol unit to the ecu. which wire should i use? or how did you guys set up for this.
many thanks
-
hi can someone help or guide me in setting up the config for fuel level in pc link to aem cd7 dash. i've wire the fuel level sender to volt 7 in the ecu.

Every time the knock threshold drops out it says it's due to TPS Delta - this setting is on the Knock Setup window. It seeems odd to me, however, that sometimes when the knock threshold isn't saying it's dropping out due to TPS delta, knock table level 4 and 2 are often dropping to zero. I assume this may be due to the sampling rate of the PC log being on the slow side. I would increase your TPS delta lockout first and see how the logs look after that.
thanks i will try this first

I believe he's referring to the knock threshold and reported values intermittently going to zero. Probably has something to do with TPS rate of change lockout or some other parameter locking out knock detection during that log. Posting the actual log would be helpful to trouble shoot.
yes this is what i meant. thanks for clarification.
On 5/26/2023 at 5:25 AM, Adamw said:If you are in fact talking about the threshold dropping to zero and the threshold table doesnt have zeros in it, then you can view the "knock system status" runtime to see what is locking the system out.

Hi i encounter dip in my knock counter logs. is this normal or is there something wrong with my setup? im currently using Bosch sensor.

Yes possible.
But unless you have a STI 6 speed swap you are going to grenade that 5spd transmission in no time!
Ok thanks and last question what's the proper way to tune a pop and bang settings?

Thanks for the information guys but how about launch control ? Possible on a wrx v4?

Hi anyone here able to guide to setting up basic guide for road anti lag? I've tried alot of setup but doesnt really work.
Attached is my map for reference.

Yes, try some more gain. Ideally Id like to see typical knock level up around 200 at WOT.
Ive got high gain at table 4 how do i lower it down? more fuel or less ignition on the cell?

It doesnt look bad - at least there seems to be some resemblance to engine noise in the shape of the knock level logged. I would typically like the levels to be a bit higher to give more resolution and I would also typically have more margin between the average knock level and the set threshold than what you have. But overall it doesnt look a million miles off. Have you still got room to increase gain?
hi apologize again for the late reply. should i increase the gain for clearer view?

hi did you manage to resolve the misfire issue? i ve the same issue.
