What are you trying to say

 

where do you see the delay? I cant make it out.

also, I guess the delay will happen with all WB and its normal ?


LEANSPOOL = the ECU leans the mixture from spool to redline?
how does this make tunning more difficult?

 

The WBO2 delay has a little bit to do with the combustion and exhaust process itself, but likely more to do with compiling multiple data sources (likely running at different speeds/rates) in to one file. Depending on the order and number of the items you are logging, the delay may change slightly.

The delay is prominent during spool up when you jump across load cells very quickly. Your log may show 13:1 @ 260 load, when the 13:1 is really coming from the 180 load cell. So, you richen the 260 cell based on the log which causes a rich area after the lean spot.

Lean spool leans the actual mix in comparison to the map. So, a 10 in the map at 2500 gives the same result as a 9 in the map at 3000. That part of it is just annoying, but disabling lean spool makes tuning fuel more logical and map smoothing easier.

The big issue is that lean spool is meant to lean the mix in a different amount depending on a few different factors ... gear (or engine load) seems to be one of them. So your AFR from say 3rd to 4th gear will change.

I've also seen odd occurrences in higher gears where AFRs will suddenly jump rich by a full point or so for no reason. Disabling lean spool got rid of this.

 

Can you see this happening in my log?

 

Not in the log, but in the images you've posted ... you've got 9's in the map but you're seeing 13's in the log in that area with a rich spot afterward, right?

 

so ill disable lean spool and run the log.. tune and then enable it and im done>

I need the link to the disable mod.

 

No, you don't re-enable lean spool ... if you tune fuel and then enable lean spool you'll run really lean through the mid range. Disable it and leave it off.

 

IMO you need to stop tuning your car, put the stock map back in it and preserve it for whoever is going to buy this thing from you. Judging from your comments in this thread, you're heading down a slippery slope. You should do more R&D before toying with the ECU.

The car has the stock map on. Thanks for the advice
In any case however, I dont undestand the movite for your response. What do you mean a slippery slope?

I think its funny how some people get frustraded when others want to learn. Im sorry but tunning A/F was not one of the things i was born knowing how to do

IMO you havent contributed at all...

 

^ Tuning is not something you learn in a blink of an eye...You need to research alot more basic techniques before considering what your doing.

Tread lightly or your in for an expensive end result.

 

subscribed....great thread

 

Wanting to learn is all well and good, and I fully support your endeavor in wanting to do so. However, looking at some of your comments and goals, I'd venture to guess that you don't have a solid understanding of what to look for in tuning your IX ECU. Normally, I really wouldn't care ... if you want to risk your engine, that's your business, but when (presumably) that same car is up for sale, putting any potential buyer at risk, I feel obligated to hoist the BS flag. Sorry if it offends you ... seems like common sense to me.

I also understand that you are trying to learn, but I do somewhat agree with Ludi on this one. Tuning is more than changing a value in the ECU. You need to know what value to change, what it should be and, even more importantly, why that value should be what you are changing it to. You should learn all of this BEFORE you start playing with values in the ECU itself.

None of us were born knowing stoichiometry or minimum best torque principles ... we all took the time to read and learn. Personally, I probably spent 30 or 40 hours just reading and learning about tuning before I even pulled my ROM off the car. After that I've probably spent another 100 hours or so learning what I did wrong after I started changing stuff on the ROM.

So, I would agree that it would be a good idea for you to step back for a few days and just read and learn ... study the principles of lambda and AFR values and their respective targets for forced induction engines. Look in to the comparison of increasing boost or timing for more power and the ups and downs of both methods. Read up on the MIVEC system and how intake overlap can help or hurt your HP and torque.

After that, come back here and work on tuning the car.

 

thanks to both of you for your help.

Ludi you are right about the car being for sale. however I have decided to keep it for another 1-2 years , but if someone wants to buy it by all means. I wouln't sell the car to someone if it were "broken" as I know it would come bite me in the butt.

I do understand the concepts, but you both will agree that theory and practice are 2 different things. You learn by "hands-on"

I will also HAPPILY say that, all these logs and map I have been working on (since using ecuedit - since I started to post on this thread) were never flashed, why? because ecuedit seems to not want to flash my car. How do I know this?
well simple, last night I went to disable leanspool and the stock fual map. I flashed it with ecuedit and I was not getting richer value at all.. if anything the same 11.XX I alway have gotten. So I decided to open ecuflash and retrieve the map on the car, and guess what it was an old old map, lets say "5 - 6 tunes ago"
NO WONDER ! so then I used ecuflash to load the stock map, logged it, and then loaded the No leanspool and it saw richer values by almost 1.0 a/f until right before redline, then it both logs hit the same mid 9.x's

Point in hand is, all my frustration and stupid questions were cause due to my ecuedit not flashing.

See logs attached,
my only question is, if we know the leanspool will lean me 1.0 a/f can't i just tune to 11.x and let the lean spool bring me to 11.9 - 12.0 (and just let it taper afterward back to 11.x)

 

I hope this works !
