Default for reference, my latest ign. map

first, the table:



and a nice graph:



overall ignition correction is set to 10*, so add 10 to the entirety of the map. afrs at peak load are 11.7.

something recent that you may notice is the skewing of the load references to provide more granularity in the 2.5-4.5 g range. so far it's worked very well. i'm in the process of doing that to my fuel map also.

I would really like to know how to use EcuEdit...I can't understand how it works when I load up my map it asks for a def. file, etc.

Is there a tutorial somewhere?

the easiest thing to do is grab a copy of xmlwrite, and use that to create a def file. the xmlwrite readme will describe its use.

then install ecuedit.

then put the xmlwrite-generated def file in the xmldefs subdirectory of ecuedit's install folder.

then run ecuedit, and open your .hex image file.

Excuse my ignorance here: What do the values in the cells in the top image represent? They are too low, I would think, to be timing (there's now way you're only running 6.37 degrees at 7000 rpm).

Yeah having the whole ignition correction map at 10 makes it easy to spot where the ECU is pulling some timing.....just look at the log files, and look for where the KC value is not 10 ! I'm running a 10's map too.

as a next step i'm going to plot out some oem ecu ign maps. i'm trying to discern a pattern of map "shape" across different platforms to see if we can make some generalizations. ecuedit's inherent graphic capacity makes it much easier to visualize these kinds of things. i'll probably ante up the money and buy a full version soon.

Yeah, the uniform KC value across the entire map is a good idea. As pointed out before, it's really easy to spot where the ECU is pulling timing. You just have to do your homework on the base map and get the values right. Are you actually seeing engine loads above 5?

i see engine loads of almost 7. a 5g load is around the 15psi boost range for me. 7g (well, 6.75) takes 25psi. i've got a thread on that subject here: http://forums.nasioc.com/forums/show....php?t=1099390

i am still running the stock airbox, stock maf tube, stock maf sensor, stock maf translation table. some addl. info here: http://forums.nasioc.com/forums/show....php?t=1118038

from what i've found, i have a feeling the vf23 is an unparalleled midrange performer due to its comparatively "exhaust heavy" flow balance. see also: http://forums.nasioc.com/forums/showthread.php?t=299097

How does the VF23's P20 exhaust side compare to my Big16g's TD05?
Is it bigger and more similar to a TD06?

i think it is closer to a td06 flow wise. this is from what i've picked up on some british bbses (22b.com, scoobynet).

it's very hard to directly compare the p's to the td's because the ihi "way of doing things" seems to go with a very large, free flowing housing paired with a smaller, tighter turbine wheel. the mhi "way of doing things" tends towards a smaller housing with a bigger wheel packed inside.

You could pick up an 8cm housing and see how that works out for you.

I am planning on doing that after I get my EGBP gauge installed

I'd like to do some comparisons before and after.

i made a rough draft 10KC map. Around my 800rpm and >2.0 Load, my total Base + KC is less than 10. If i set my KC to 10, then i would have a -value for my Base Ignition Timing. Is it ok to do that as long as my total ignition timing is the same?

Yes, it is ok to have a neg timing value in the base map. You could actually run a negative value for total timing. It would just mean that your spark is AFTER TDC.

Ken, your timing map is 99% identical to mine.

Search my noob friend. You will find that Ride5000 has probably one of the fastest, self built, self tuned, low budget WRXs around. Oh yeah, and he knows his s**t.

yea, i know he knows his ****. i've read plenty of his posts. i also believe that its possible that he has added something or taken something out since he last posted his mods. Is it wrong for me to ask what his CURRENT mods are?

Morning nasioc people just like to read and write/chat to others anyway. Just like in real life, if you go to a meet and walk up to a guy that has his hood popped, is it wrong to ask him what he has under the hood to spark a conversation? Or would it be a bit rude of him to say "search under my hood, my noob friend, its right in front of you."

Also, free bump for his reference thread, that's always a friendly gesture.
