Big Map translator is in post #3 (https://www.evolutionm.net/forums/7597112-post3.html).

But where is the Big Map AFR calculator posted?

I just converted a JDM IX to 88580714. It seems to work okay except that the launch rev limiter and possibly the launch maps do not work. Anyone have any insight into this?

With the 90550001 v5 ROM that i have the most experience with, there was a seprate launch limiter tab within the tephra mods, as if the launch limiter was moved to a different location, but I don't see this in V7. Maybe it was moved but the XML was created without pointing to that location?

Thanks for your help.

make sure he knows to manually do the timing map, the big map sucks to convert the timing map, but does a ok job with the fuel map.

the calculator works for both... i use it for both without any issues. A few minor quirks to work out with cell formatting, but after that... piece of cake.

nah the rev limiter does not work i had 8858 on my JDM IX early last year i believe its the ecu pinouts.

i recommend you go with 8857, until V7 comes out for 8857. EVERYTHING works on this rom. PM me if you want my copy i put together for 8858 or 8857.

well, w/ all of the comp. issues Im having, (getting ecuflash to load up a completely fresh app) I finally got what looked like a clean rom, swapped all of my maps, and I can NOT for the life of me, get my gears to recognize themselves... (88590715)
I have rpm_speed_ratio logging, and is almost dead on w/ whats in my gear map...
Every time I think things are good, somethin else pops up...
Heres what I have im my map...
1-6
30-5
43-4
55-3
75-2
110-1
1801-0
the value in the MUT table for 40(gear) = 8447, and yes, I have the correct request ID in evoscan.

am I missing somethin?

After crawling under the car and listening, I found that the intercool manual button actuates the EVAP purge solenoid on my US '04 with 9653706.

This kind of thing is the reason why I went with 94170015 V7 or 94170715 if you like...

Hey dude,

Thanks for your rom file.

I've tried the "Knocksum Required for Slow CEL" and "Knocksum Required for Fast CEL" and it does not work in my case.

Any idea why?

At the same time, I'm wondering if the V7 for 8857 will be launched anytime soon?

rolly1818

it should work, always worked for me, shoot me an email and i can look at your rom. i am sure your missing something.

i am patiently waiting for 8857 V7

I had asked this question in a different thread but didn't get any feedback on it.
I just recently installed 88590715 and all seemed to be well apart from the map switching function. I've got the JOT harness and the problem I'm having is that the alt map activation is stuck at "4" no matter if I'm on the alt map or normal map.
The actual switching function is working based on the logged idle timing (I set the alt maps a little higher) and also the logged volts (0 volts when off, 4.58 volts when on)
The funny thing is, when I load back my V5.10 patch it works just fine (0 when on normal and 4 when on alt)
Has anyone had any problem with V7 in regards to this?

I've noticed an issue lately, while running on ALT maps the car idles 500 rpms higher cold or hot. Im not sure if its e85 related or not.

Also Im not sure if its something to do with v7 or the fact im running 9653, during deaccel throttle AFR's go super rich! Like almost 2-3 points lower. Im wondering if I need to work some fueling in the deaccel.

I hope for answers.
Thanks guys.

Sorry if this is redudant and has been covered previously but, I searched all of this thread, Mr. Fred's direct boost control thread and the GM 3-port thread and couldn't come up with answers. I've finally decided to ditch the tried and tested MBC on a few cars and am currently working on a '05 MR running SD ad e85 with a Perrin 3-port EBC.

I read over Mr. Fred's directions on direct boost control and have a pretty good understanding of how the system works. I have setup the system to be a PSi based system.

The issue I'm having is the I cannot get more than 22.4 psi of boost pressure (as measured by an Evo X MAP sensor). I am only in the initial stages of tuning the boost so all my correction values have been zeroed (BEC table, TPS WGDCC, Mac WGDC v. coolant temp is maxed above @ 127.5 above 176 degrees). I'm trying to achieve a max of 28 psi gauge pressure so I have the Boost Desired Engine PSi maxed at 24.6 throughout all gears and the Boost Adder PSi set to 18.1 which should give me a target boost pressure of 28.

I've fiddle with Main WG map with values ranging from 90 up to 127.5 but, cannot seem to achieve 28 psi.

Also, in EvoScan I don't think Boost Error, WGDC or WGDCC are logging properly. The Boost Error remains unchanged at -3.087 and I get no date for WGDC or WGDCC.

I am using 96531706. I couldn't seem to find the MUT values for Boost Error, WGDC or WGDCC in any threads to confirm I have the correct values in the MUT table. Currently the table is showing 8D1B for Boost Error, 8D23 for WGDC and 8D21 for WGDCC. Are these the correct values? I believe the Boost Error and WGDCC is correct as these are the values that are inputted for the Global Boost Control Type for PSi but, just wanted to confirm as I don't understand why they wouldn't log unless one needs to be in front of the other in EvoScan....

If you have error correction off (zeroed) then the Boost Desired Engine PSi and Boost Adder will do nothing, you will run purely off base WGDC.

127.5 in the WGDC will do nothing, 100 is max. Sounds like you have the 3 port installed incorrectly.

The MUT (to change to) changes in the current 96531706 are incorrect in the XML. If you change them to what is shown in mrfreds "direct boost control" for the 96 rom then it should work correctly
