Data Logs! Post them here.

[Tor]

Thank you very much for your help. Will play with it tomorrow and go for a quiet drive with varying low load rpm on back roads.

[BXRCHTR]

Can someone tell me if this looks right? If not what are the things I should change on this tune to better suite my car.

Ps. Correct me if I'm wrong but isn't e85 supposed to have a different afr than gas? If so, why is it still trying to get 14.7:1 afr?

Still a huge difference than stock!

It's running rich.

You need to tell us how many km since flash. The log means absolutely nothing if we don't know that the ecu has dialed in the fuel.

Repeat this:

And log LTFT and MAFV.


The AFR is directly converted from O2 sensor after combustion, it doesn't show AFR before combustion.

And read the threads in this forum section.


If LTFT which isn't shown has been fully adapted by the ECU then it looks like you would need the "US.Lean" scale from here:
https://docs.google.com/spreadsheets...R3Y/edit#gid=0

That will make it up to 3% leaner at the very top.

Here I just did a 3rd gear pull literally 10 minutes ago. Let me know if this is good.

Edit:
Ps. Above 500 miles since flash on this one.

Your LTFT is crazy high. Are you on a 93 tune with some E85 in tank?

You're missing most of the useful parameters... AFR, Commanded AFR, FLKC, IAM. Log those and come back.

[BXRCHTR]

That's why I'm here. I have the e85 stage 2 tune but I'm not sure why LTFT is that high. I'll log it tomorrow and do a couple road dyno 3rd gear pulls and let you guys see whats going on.

You're either running a 93 tune or you've got a big leak. Double check that tune.

[BXRCHTR]

Oh shit... Now I'm scared. I will check right now.

[BXRCHTR]

So it is on stage 2 e85 el. I just reflashed it just to make sure. So here is a tiny run I did.

Try stage 2 e85 UEL and see if the LTFT changes any. If it's still the same, chances are it's a car problem, if it changes, it's a tune problem.

Hi, running an E85 EL @Wayno tune, looks OK but high LTFT?
Any issues I can fix?

BTW, D00G rom so IAM etc don't work

looks fine , the ltft is only high at very low loads/idle
AFR and commanded afr are good, KC Learned shows no sighs of knock, got full 33 degrees at high rpm/load




IAM, FLKC MAF V don't work on D00G oft logging


you could add about 7% to the maf flow numbers called MAF if I remember correctly , not logged in that log) at/around idle maf flow rates to sort it but not really necessary

[CZ6T]

Ok, so I posted a log a little ways back, asking about why my AIM, FLKC, and MAF voltage don't work. Seems like its bugged for my ECU, Z00C, or something similar I think.

Anyways, I've had maybe 5 or so fillups now, and have also changed my headers to a catless EL, and the exhaust(which I don't think should change anything).

I've gotten Romraider downloaded now, and checked my KC Learned against the Knock Correction table A as suggested by @steve99 , and aa far as I can tell, everything looks spot on.

But, I'm wanting to know how concerned I need to be about the 4 dips for Knock Correction in this log. It happens around 2500-3600 in each instance, but this is the only log out of 3 I took that day that shows timing being pulled at all.

Any insight is definitely appreciated!

P.S. this is Shiv's OTS E85 EL tune.

I see 2 instances of actual knock retard in that log, however it's not worth worrying about. It's only happened once.

You haven't logged engine load anyway so even if you wanted to pull a little timing then you wouldn't be able to.
