New guy, new build

[madmike]

Hey,I've only cracked a couple cylinders and I think all were 'Used' my buddy gave me,, Yea I probably had some detonation(supposed to wear hearing aids) but I drive this on the ragged edge of insanity,,, my foot is always 'in it', that's what I built it for,
and IT RUN'S 11's and GET'S 26-28 MGH
can't beat that but it does take me a few hours to swap out the cylinders,, but I 'm retired and having fun,, don't mind wrenching, I build a few VW motors once in a while to pay for new parts

Is it normal to have EGO and AFRs so jumpy just cruising? I have ego set to 10% authority 2% steps and 32 ing events. My afrs seem to swing way more than when I was carrbed.

I don't think I've ever ran ego.

Really!? I thought everyone did for just cruising.

[buguy]

Everyone might! Just not me. I do think many people get their tune super close then turn that on.

[chriswillrise]

anyone know how to fix these lean spots when you just barely open the throttle like from a stop light and taking off.

You can try accelerator enrichment should be TPS or MAP based not time so it should clean your stumble up.

I posted a picture of what my AE is set up like in the post above

It could easily be your lambda delay is not set up correctly.Log your accel enrichment and see if you are actually getting any extra fuel there. That is a pretty small tps change and your fuel table should be able to give enough fuel for that.
That is why it's important to have the lambda delay close....so the correct bins get changed when it needs more fuel.
Most small throttle changes should be table adjusted so you are not dumping a bunch of fuel in for every throttle movement and causing rich spikes instead of lean spikes. It's a fine line on when to use accel or let the fuel table take care of it.

I do log my accel enrich. That pedal press wasn’t enough to trigger it and I went way lean. How do you set up the lambda delay? I really have no idea how to do it

[Clonebug]

Lambda delay is setup by watching events on your logs.
You can also set up an event or two by setting certain table areas rich to be able to log the event.
You can also watch the log and check for events that have a delay from tps or VE to AFR.....
You then left click and drag to highlight the area from say a tps movement to AFR change....or VE event to AFR reaction.
When you click and then drag to the end of the event you can see the time frame at the bottom of the screen. It will give you milliseconds or thousands of a second and you can input that into your lambda delay points.
Check the rpm and map area that it happened and input a new number......if you happen to see another event you can set the rpm and/or map line and change that too.

Think you could help me? I can pay for your time
I have a bunch of logs just from driving back and forth to work all saved on my laptop

[Clonebug]

Send me your project folder and a few logs from a fairly long drive and I'll see what I can do.
Actually the project folder will have all your logs in it so I can check them......just make sure it isn't too big to send over email.

You might have to compress it into a zip file. Just make sure there isn't a whole bunch of logs. The latest two or three should be enough.

Either that or make a new log without Autotune running. That way I can see what it actually is running like and not the Autotune chasing itself.

alright ill send over the project file and 90% of my logs are just dated so itll be east to tell which ones are recent. I also havnt run auto tune in about a month so the recent logs should be ok.

i dont understand how im hitting 190 intake temps with water meth. its so frustrating. Im getting detonation at 13 lbs of boost and 16 degrees of timing because my intake temps are so damn high
