tscompusa -

What is your load and timing at peak torque? I use good ol fashion 2 byte load so it doesn't clip, but I'm old school and don't bother with the 2->1 byte conversion thing.

I run around 0 degrees to 4 degrees of timing at peak torque, and this is based on conversations with JohnBradley and GST, and lots of pulls and logging. 12 degrees out the top is safe for sure. You may be able to get up to 17 or so.

 

Im a little confused on what this will do? Could you explain it a little bit more?

Two side notes as well. I was getting gas this afternoon and I happened to check my oil level. It was a bit low for some reason. A little below the low level notch. I had about 1/4 a quart of mobil 1 kicking around so i put that in. it will most likley need another 3/4 quart of oil to get back to full. I never had a problem loosing oil before. And I dont see any spots under the car when i move it although its tough to tell when its so wet out. Could low oil level cause knock? I feel like it prob could...?

Another thing I just realized is that I still have a Turbo XS UTEC installed on the car from wayyyy back. I never actually used it and kept it on map 0 all the time which is supposed to be "bypass mode" Ill try to take it out this weekend just to be sure but could it be causing problems with knock and maybe even effecting my data logger?

A bit off topic, but I just wanted to add a little side note to this. The top mark isn't a full mark, it's a max mark. Ideally, you want to be between the two marks, especially if you don't burn oil. Too much oil is as bad, if not worse, than too little. You can aerate the oil, causing foaming and oil starvation.

 

the logs i have really aren't telling me much, on some pulls i see 300 load at 3200rpm, and others around 3900rpm is where it maxed and was clipped at 306.

according to the log the max load was seeing 6* with 2 counts of knock. ill knock it down some around 4 as you suggested. another member on here sent me a map to use to test, but i thought it looked to aggressive ill post it.

cars down atm, since im fixing phantom knock issues but will be taking it back out and doing some base pulls but i want safe maps for base pulls and i really need to know which LOAD is the best to log and go by since that is very important tuning the map

heres 2 the one with the smoothed negatives is the one i was given to try and the other one i was messing with based on another e85 map i seen here.






im going to do the initial tune with the 9417 rom since i already know how the car acts with that rom. let me know what you think.


isnt the 120-140 load columns a bit much also?

-- edit ---

i was viewing your build thread, very impressive car you got. i seen your e85 timing map and im just going to copy it since we got a similar setup and its mild. the ones i posted are a bit aggressive for a starter map. my old maps were all 7's and 8's it doesnt get much more aggressive than that at pk tq, so your map should be 10x safer.

I cant find this section in EcuFlash...

I have seen on a recent cruise log what i believe to be "phantom knock" Can you confirm this? I have posted the log look around line 650 I have highlighted it in red so you CANT miss it.

And what the purpose of this "Idle Stability timing control"

Thanks

that looks like a typo. appauld told me to do the same and it was called the knock sum decay timer .

 

I dont have that either though??

 

its under Knock control. id imagine its "knock load"

 

Ok so under my unmodified EcuFlash XMLI dont have the knock control section. But when I open my ROM in my modified version of EcuFlash with the XML file the tscompusa sent me for the tephra mod I do have this section. Is that something you have to add to the "stock" XML file in ecu flash to see?

-ethan

 

yes, but why are you still bothering with the non tephra xml?

 

Because I couldn't get it to start. with the tephra rom. I was going through the original v5.10 release. Since the car didnt start with that rom im trying to find the information on here of how to setup the v5.10 mod.... Your xml had quite a few extra tables defined then the originally released v5.10 xml file?

There has to be some direction written down somewhere on how to setup the Tephra V5.10

 

ill take another look at your rom. it probably didnt start because the immob hex is for a 2004 evo and 2003 is different. if you search the forum you'll find stuff everywhere.

 

Shoot me a PM with your email.....I will get you going in the right direction with 5.10.....Too Easy.

 

ive been searching on and off for a few days now. But im no t giving up yet!

Also if paul happens to come back to this thread I saw something he posted on another thread about "Idle Stability timing control" and posted this table

<table name="Idle Stability Timing Control" category="Timing" address="174e" type="2D" level="2" scaling="uint16">
<table name="Settings" type="Static X Axis" elements="3">
<data>Sensitivity</data>
<data>Timing Limit</data>
<data>Untested</data>
</table>
</table>

You were saying something about raising the sensitivity from the stock 128 to 146... My idle is a bit more unstable now compared to how it was with more timing at idle. Maybe I should change that back as well. It was at 14* idle and not its 10 to 8* at idle.....

i already gave him the rom already done. ethan send him the rom / xml i sent you or ill forward it if you give me your email appauldd. its funny how my car fires right up with the rom tho.. and of course i set his immobilizer hex to match his original rom.
