That still doesn't make sense because your log is showing -4 degrees. Neither your high or low octane maps are showing a -4 anywhere close to 220 / 4000. You must have some more hidden timing maps or another function that's pulling timing.

I can't help you beyond that as I don't have any experience with the evo 7 ecu. We'll need to wait for some others with more experience to speak up. I know there's a few periphery bits that you can shut off on the evo VIII and IX, but nothing that I can remember that would pull timing mid pull.

I have a feeling you have some other hidden timing maps.

 

Yea, the timing matches pretty close until about 2800rpm 160 load, then the timing drops quite a few degrees lower than what I have in the map.

Heres another log with the changes you suggested. Still knock about the same place, and timing getting quite retarded.

EvoScanDataLog_2010.03.16_19.54.39.csv

 

I've got an excel sheet that converts csv logs into a map tracer. I'll post up the picture and the file when I get out of work.

It's still showing that your logged timing isn't matching your actual timing, and then you can see it pull ~6 degrees when it hits the knock.

 

Alright, here's your timing map compared to what your log is actually showing.



As you mentioned in your post, you can see that in the 120 and 140 load ranges, your logged timing looks to be following your timing map.

As your load gets higher and higher, the differences become greater & greater to the point where in the 200 & 220 load ranges, your logged timing could not physically have come from that timing map.

I have only logged when you went full throttle and before your log showed any knock. So there should be no timing pull for knock in this trace.

Something else is pulling timing from you. We need the ECU flash guru's to chime in.

Can you send me your rom so I can take a look at in in ECU flash?

 

Airtrek runs 2 x highoctane fuel n timing
and 2 x low octane fuel and timing maps

Timing n fueling do not match up is mainly due to the TPS setting
Notice at idle you're running 14.1%, set it to high 12 or 13%, you should b getting everything line up according to maps in terms of load column.

My DD runs the same RON95 fuel as you.
RPM / AFR / BAR:
3562.5 / 11.5 / 1.5
4062.5 / 11.1 / 1.6
4250 / 11.5 /1.6
4562.5 / 11.2 / 1.6
5000 / 11.2 1.55
5593.75 / 11 /1.5
6062.5 / 10.8 1.45

Spooling up 2200rpm at 13.9 richen to 12.1 at 3000

 

Can you help me understand how the TPS sensor being out of adjustment affects the timing being off?

I'm not saying i don't believe you because I know I don't know that much about the ecu, but I thought that under no knock & open loop that the ecu pulled it's timing from the ignition map based on load and RPM.

Is this not the only condition?

GregM, here's the map tracer I've been using. I have it saved with your most recent log from post #47. Let me know if you have any question on it.

I do not go into machine language
Its through trial n error that I found out if you increase the TPS output voltage for the same throttle opening, Airtrek ECU will actually pickup the fuel cell closer to the higher load band in the map(richer cell)

The little device I created to increase the ramp up rate of the TPS output towards 5v with a flick of a switch and its varified in the dyno the torque curve actually shifted forward n comes in earlier, thus achieving the SO CALLED sports mode in the Airtrek Auto tranny.

 

There are a second set of fuel and timing maps, just like the Evo GTA. My 2nd set of timing maps are smaller, so have removed 0-20 load and added in 200, 220 and 240, as they jump from 180 to 260 load. I then copied my 1st set of maps into the 2nd set of maps. Apparently Maps 1 control Neutral, 1st and 2nd, and Maps 2 control 3rd, 4th and 5th gear. This makes sense as 2nd gear pulls are clean, but 3rd are a mess. I would have expected with both sets of maps now being the same, that my 3rd gear pulls would be better. This is not the case thou and timing is still about 5-10 degrees lower than whats in my map. So there must be something else pulling the timing back for those higher gears.

Just to explain further, the Airtrek as 8 fuel and timing maps. 2 Hi Fuel, 2 Low Fuel, 2 High Timing and 2 Low Timing.

I thought this was the missing link, but obviously not.

 

This is still driving me crazy, 1st set of maps are sweet, so have run 19psi in 2nd gear, no problems, yet 3rd gear pulls, even with the 2nd set of maps being the same, timing still doesn't follow them and get knock even at 12psi. I guess no one has tuned a GTA or Airtrek and had this issue?

 

What intake pipe are you using?
With TD05 you can't be using the stock intake pipe which is meant for td04.
You might want to look at MAF rescaling?

You mentioned your 2nd sets of map is smaller? I think your xml is not defined correctly.
I just look at my ecuflash, both sets of maps are identical in size.

Ignition Map addresses: "3b9b" "3cfd" "3e5f "3fc1"

 

I'm running an aftermarket evo intake pipe.
Could you send me your xml and rom?
Those addresses are correct, only my Hi Octane 1 is a big map, the other 3 are smaller - 3 columns less and jump from 180 to 260 load. I have rescaled the maps to start at 30, and added 200, 220 & 240 load to them..

My rom is 89970010

 

Big break through this morning. Someone else opened my maps in Ecuflash and saw some issues that I don't. I have my high octane 1 map show 0-260 load, yet my other 3 show 0-260, but missing 200, 220 and 240 load. I adjusted my scaling to add them in. When this other person opened them up, they saw the 0- 260 load as it should be, with all 4 maps being the same size, yet the extra 3 columns for 200, 220 and 240 load are massively retarded. I can't see these columns to adjust them!!

This could be an issue with my xml or ecuflash. If anyone has any ideas, let me know.

 

Finally!!! Good news!

 

Just adjusted all the maps and uploaded, thought I'd be right, but as soon as I go on boost I get massive knock in all gears now. I even went to my initial rom I uploaded and that is all up the crap too. I really need a clean rom and then go from there. I'll keep working on it tonight
