I think we do since we need a set base point for the ECU to make calcuations from that fall under, say our lowest point, 500RPM or 10 load.

 

Holy crap is that just like the subaru ignition correction table? Were its added that on top of base timing.

 

Seriously you guys didnt see the thread? Okay I will link it but only this once since I like all of you

It doesnt work as fast as the Subaru version unfortunately. If it detects 1 count of knock it will default to the normal map immediately. Sometimes it works and others you cant see it in the map. I am sure there are other maps that we havent uncovered that determine all the variables, but until I really dive into disassembly (and get the time to do it proper) or someone else does we just dont know.

0 load must be there for limp (blown pipe for instance) and some other base calcs...taking it out will probably work still, but there is no point when you can alter the rest of the table as I showed...Even the VIIIs have plenty of interpolation and space to make it work.

 

Fine the 0 can stay,lol. But I want more dammit! I really need to kidnap Tephra at gunpoint, threaten to T-bone his new car just last the last one and have him show me some diasm stuff,lol. Or I can beg...begging sounds better...I don't like guns, or dead evo's.

 

lol

 

Now that IXs have 1 ignition map, I wouldnt mind seeing it get boosted to 26x26 or something obscene. That reminds me I need to re-up on the Tephra fund.

 

Yeah, I want one kickass set of maps. Why should the stand-alones have all the fun huh? Tephra is working his butt of with these patches and deserves quite a pat on the back, not to mention he's still browsing the threads to help us newbies out,lol.

 

This rescale was from a few weeks ago to show what you can do with the stock map if you work with it a little. Obviously its for a IX and you have an VIII but again it shows what just dropping the 10 and 20 can add. In the case of the VIII you'd be to 300 with no other changes.

 

What do you mean by the first statement ???

 

With the new Tephra v5 patch he eliminated the multiple ignition maps for the IX's and there is only one.

 

Ah, nice... My Evo's been down for a week now waiting on tranny upgrade so I'm behind

 

Sorry to keep going off topic, I am just curious. 32.7psi on straight 93?

 

Yes, straight 93. Shell V-Power Stuff only.

So I found out something extremely strange yesterday. I popped off my valve cover late last night to make sure that a few things were still good under there, and pulled my plugs to read what was going on.

Two of my freaking plugs were BR8ES, and two were BPR8ES's. What the hell? I pulled out the garbage and found all of the boxes that the plugs came in, and yeah, all the boxes said BPR8ES. I think these were from the box of all new plugs a friend gave me after he sold his Evo. He must have not put them all back in the same boxes or something. I doubt NGK would have gotten that wrong. And I remembered when I gapped them I was paying more attention to my future wife Stephanie March on Law & Order more than my plugs.

No wonder the car was running wierd. Maybe tonight I will have some really good data logs to look at then, and post up.

BTW, it's a heavily modified IX turbo.

 

So, I rescaled the maps, and the driveability of the car was immediately improved with the resolution brought back into the low end of the car. I am still getting some knock, up to 7 counts, always in the 27-3500 range, usually from a standard start off from a green light. that part of the timing map was brought back to stock, so it looks as though I am needing to take even more timing out in those load/rpm areas. I am surprised, I have taken almost 6 degrees out of that area of the map, and the car still consistently knocks. (The counts are going down as I pull timing.) Anyhow, here is the rescaled load values I am using:

0
20
40
60
80
100
120
140
160
180
200
220
240
260
280
300
320
340
360

I was able to add a lot of timing back into the 100-200 load areas, and in some cases, almost 5-7 degrees more. The car has regained it's low end pull during spoolup.

So, tonight I am going to go out for some pulls, and get the afr right where I want it, along with boost and timing. (And others as well).

Should have some interesting data logs tomorrow, or Wed to look at.

Bryan, I am sure you might want to take a look at them, as you seemed kind of curious as to my 32.7psi on 93..

 

Oh yeah now I remember seeing that.
