Oh well at least you have a baseline. I think mpg especially in real time on the dash is a good indicator or tune, but I think I’m with @Buccaneer . MPG was something my old man cared about but I never have.

 

It's ALL good guys, I'm just busting your B**** on the mpg thing. I actually laughed out loud for a second about the mpg posts. If mine was at 14mpg, I'd be pretty happy about that with my foot planted squarely on the LOUD PEDAL. Carry on... BTW, I will be calling Bob at Dynamic EFI shortly about some ECM.questions and will ask about the small/large cap latency table. I think Bob and I have talked about this before, but I could be wrong. Have a great day guys.

 

I track it on my daily. It actually has helped to identify problems before they presented themselves... usually a small drop. On this, IDGAF. I just want it to work. And being I'm doing 6k shifts foot firmly planted and still getting that I'm all good. I will probably get it close and forget about it lol.
If you don't mind, post up what he says if he is okay with it. My understanding was small cap = points closer together, external coil so more charge time needed and large cap = internal coil more actual rotation time so less needed. but IDK.

Now a quick question for the braintrust @Buccaneer could maybe ask bob what he thinks of this too. On very light throttle, 25mph, 4% 1800 rpms, im bucking. It doesn't do it in open loop but open loop forces a slew of other things to change too. Basically what I am seeing is if I get out of async, WUD light goes off, it stops. Now I am going rich lean at this point bu my map is rock solid and the VE table in the area is pretty flat too. What I've noticed is the injector DC is going 10-9 to 0 then back up while in async... So I am thinking it is an async problem. Also I believe async is disabled in open loop and is the reason why I don't feel it there. Mind you the throttle input is so light that it is just enough to maintain speed on a flat surface. any more it accelerates and stops, any less it coasts and mostly stops. Ive flattened timing in that area to 39 degrees and it helped some but more or less than that and it gets worse again. wideband shows a jump from 14:1 to 18:1 as it bucks, inline with the DC.... Thoughts?

 

hey i like to see how much fuel i can drain per outing!
i was excited when i found i could drain a half tank with a few extended pulls!

 

Firdt, make sure you have learns set to use your wb, and that you have the wide band setup correctly in the whats up app.

second, you need to calibrate your wide band every so often.

third, remember what i said about the 3001 O2 sensor settings?
i had weird issues with open loop wide band learns.

also each learn can only learn like 12 or 16 numbers.
get a learn change, save, apply and learn again.
i rarely even shut off my engine while i apply the new bin.

bucking is usually lean.

 

I matched everything to the tb4 bin though. Openloop the learns hardly change now with the wideband too. Bob suggested to me a while back to do a few narrowband closed loop learns too because that is how drivability builds. unless I interpreted that wrong... and again. Doesn't do it in openloop. Which is why I am confused...

 

@Gibbles I oofed and didn't transfer the async values from the tbi4 file. After doing that 90% went away. DC is still dropping to zero but now AFR is only bouncing between 14 and 16. That being said it is now happening higher in the rpm range at 2400 and 8% throttle. Again though it isn't going lean now just like an on off on off... kind of like when a carb is boiling... its more of a surge i suppose. The wide band is adjusting to +12 in those areas but for whatever reason is only showing a .2 or .5 increase in tuner pro in the VE tables. Weird.

 

Update 2: fixed it. I smoothed out the fueling areas a little more and that took care of the 2000-2500 range. It just didn't like stoich and wanted to be a little fatter.

 

And so continues the endless journey
How do your plugs look now?

 

Guess I should check that shouldn't I.

 

Well maybe run it with the new map for a while. I was asking because you leaned out the fuel table a little while ago and your plugs should look pretty good now.

 

now that its warmer its getting fatter again though.

 

Yeah and also I heard that the corona is an oxygenater

 

@Gibbles I got the cold start sorted it seems. Also... i thought more rpm was supposed to tame a cam, not make the thing sound like the staging lanes warming up lol. I've attached a video for your pleasure.

 

That makes me happy

 

me too lol

 

Getting there!
I have a pretty high idle.
Lots of what I wanted was my idle to lower in a timely manner.
I think the settings are Throttle follower or "TF" in EBL

Also notice I have Idle SA fixed, that keeps my rpm a tad lower.

 

I have it higher... it did not like to start at 900 so I kept bringing it up. 1400 is nice because it only does that to ~130. So a warm day it starts at 1100 and kicks down with in a couple minutes (I hope). Helps warm it up too. I have a warm weather idle rpm ramp setup too. Having it that high hides the lifter tap when it's cold... i really have to fix that but it seems like a flow problem cold.

 

Just hit me, I wonder if that's why I have issues with hot restart...
something to play with I suppose.

 

I think it sounds awesome!! It fires right up and runs so nice! Great job!
