It's just what it does. There are different regions where LTFT is set, it's not a single figure for the entire range.

post up the datazap log, it probably need some maf scaling, f your not on stock intake

Ya it's not stock
It's the ace takeda intake
I'll post the data log in a bit and maybe u guys can help me take a look

[Dragon780]

i was playing around with romriader and compared the stage 1 and stage 2 UEL tune,

with the stage 2, why are alot of the values for everything 0?

here is the data log, i did some regular driving at the beginning shifting around 2-3 rpm and after i did a pull reaching close to WOT

this time my LTFT is always around 14, i believe i do need to change the MAF scaling.

thank you for checking this for me,

if you're comaring them, it shows you the difference so 0 means no change. The menu of the open table has an option to turn that off to see the actual values.

I also opened the stage 2 up alone and those were the values
I meant compare just as in opening both maps up to look at them indivicidually

Sorry for the misunderstanding

if you post your logs up to www.datazap.me they are much easier to read in graphical form.


Yes look like maf scaling would benefit you ltft varying from -6 to plus 10 or more.


could not see any full throttle run to redline in that log though

Is the template added at the bottom of the first post still the most current? I am having the 0 IAM issue and am wondering if cal file "F00D" isn't current.

Edit: No MAF voltage either, probably need an update. What would be the best way to contact OFT where they aren't swamped with messages?

I'm having the same problem with my cal 'F00C'. I sent openflash a message through their website 2 weeks ago and I PM'd shiv on here over a week ago. If anyone can help with this it would be greatly appreciated.

A potentially dumb question, but with the IAM not registering, wouldn't I be able to just monitor the timing to determine if knock is occurring? It would go negative right?

If IAM monitor is not working, then you can derive the value from the KC Learned parameter. The latter is NOT knock, but the knock correction learned ignition advance. It is derived from the "Knock Correction Advance Max A" table in ROM and multiplied by IAM and subtract FLKC.


So, you'll need to monitor Engine Load, Engine Speed (RPM), KC Learned and FLKC. You'll need to have also the table values of "Knock Correction Advance Max A".

Thanks for the information. So while driving, FLKC and FBKC should stay around 0. FBKC will register over time but FLKC will be instantaneous. If FLKC is less than 0, the negative would added to the IAM (I can't currently see) to show the KC learned?
