Is there a way to run V7 with an older version of ecuflash, such as 1.29?

The reason being, as I'm sure many of you have heard about this, the older tactrix cables are not recognized by newer versions of ecuflash (((((

 

First, let me start by saying I'm fairly new to this calibration work on my 06 Evo IX MR.

What pulled me towards V7 is the ability to simply simulate the rear O2 sensor (signal and heater) and the large maps.

Here's my scenario: I have taken rom 88590715 and modified the immobilizer to match mine. There have been no issues with starting, but I can not build boost over 1 bar. With the stock rom, I can build up boost to 1.5 bar with a service engine soon light on the dash. I compared all that I could from the stock rom 88590015 and came up with a couple questions.


I wasn't sure if this had anything to do with it or not. Let me know your thoughts.
It is interesting that when I change this to match the stock rom, my vehicle doesn't start.


I also thought this was interesting. The value in the field is neither of the recommended values.

Let me know if you have any ideas/suggestions/requests for additional screenshots.

Thanks in advance.

First, 88590015 is correct and on 88590715, the scaling or address for TPS (the left side of the map) is wrong. If you go to the correct one in ecuflash, right click, then edit map, you can see what scaling and address the correct has. Use the same scaling and address in the incorrect one and then close and reopen the table (you may have to close and restart ECUflash).

The second one I dont know, because I havent messed with the monitor patch on the IXs.

 

no old school love??? im gonna see if i can get V7 fired up with the 1.38 hack

i

 

Is it possible that the egr patch and o2 patch on the v7 can create a conflict with the obd ii inspection patch, thus giving the heater catalyst, egr and o2 as n/a instead of ready?

In other words do you need the patches activated or disabled in order to show the obd monitors as ready and not n/a.

Has anyone come across this issue?

For the history I am using the 88590715 with option 2 from the first page...

 

I finally took the leap to tephra last night. I copied over everything, used the bigmap translator, and took my time going through everything to transfer everything over.

Running an evo IX with the 88950715 recompile modified map.

Now at WOT it is incredibly lean - high 13 low 14 AFR compared to mid-low 11s pre-v7. Also stutterbox is way different and gets over 20psi but the knock cel starts flashing.

 

Hey man, easy way to make v7 workable with tactrix 1.3:

You have to install 2 versions of ecuflash, 1.42 (or newer if it exists) to use and modify v7, and then install another instance of ecuflash (1.39 to use tactrix 1.3) to be able to flash your rom.

Very important though! You need to go into options in v1.39, and set it's rommdata and metadata access locations to the folders used by v1.42, or 1.39 won't be able to open the v7 rom at all.

Let me know if this makes sense. This method has been working just fine for me.

 

v1.39 works for you with the tactrix1.3 cable? I know there is a hacked v1.38 floating around, is that the one your talking about?

I was going to modify my tephraV7 on v1.42 and than open it with v1.29 to flash onto my ecu, but it seems like v1.29 screws up the data tables on tephraV7.

I'm gonna try doing what you just said, but I think ecuflash v1.29 is the only one that seems to work for me with the cable.

 

I owe you a 12 pack

ecuflashV1.38 reads tephramodV7 perfectly and with the hack the tactrix 1.3 cable works as well


thanks man

happy tuning guys!

 

Good deal!

Edit: v7 related question (maybe general tuning, map is still mostly stock tho), and I'm putting it here 'cause I don't want to start a new thread or clutter one less related, but on my way to work today, I was having a bit of fun and got a bit sideways in a corner in 2nd gear, I let off for a brief second, and then once the car corrected, jammed it. Car bogged badly, almost like I didn't hit the gas at all. It's only done it twice (same brief drive to work), and only since I flashed v7. Ideas?

 

I can not find Map Sensor settings for the 96530706 rom, but they are in the 9417 rom

I don't want to use boost control, just logging through evoscan, but need to be able to adjust the settings for either a JDM map or the omni map. What do I need to change in order to use the 9653 rom to log boost?

EDIT* If anyone cares or reads this post, I was informed on the answer. The 9653 doesn't actually use the MAP sensor, because teh car it came on didn't have one. There is a Speed Density rom available that uses the MAP, and the MAP still sends data to evoscan when you check the proper address, but the MAP sensor just isn't "used" by the car in calculations. This is partially why some people use 9417 if they can, as they don't see as many idle issues. I'm pretty sure now that you can just swap the map out if you have 9653 with out doing anything to the rom. Can't wait to log boost....almost wish i hadn't even bought a boost gauge now.

 

Nothing... the 9653 roms are just plug and play...

 

Anyone have any info for guide lines, for decel fuel values if you're getting rev hang?

Am I supposed to move all the values in all the maps?

From reading this thread it seems like some say to just move the main maps... afr, timing, injector scaling and latencies, but than it looks like all the other maps have different values in them as well.

I'm just going to go map by map and adjust the values to how I had them in my original map.

Some maps have different scaling for different maps going from my old ROM to V7 so I should just edit the scaling to read the same as V7 and move the values over and than edit the scaling back to how it is in V7?

If I do this than the values change compared to how they were originally in V7, which means that I have to change more than just the main maps( timing, afr, injector) because the values are different in other tables as well.

One last problem I am having is that my original ROM goes up to 7500 rpm for all the "loop" tables, but the V7 goes up to 5750, because after 4000rpm in V7 the tables increment by 2500 instead of 500 rpm like they do in my original ROM.

Should I just manually change the V7 RPM values to reflect those in my original ROM.....

In my afr map I just interpolated the 250rpm values to fit in.

Heres a pic of what I mean.


Original ROM is 94170008 V7 is 96530706

thanks guys
