ECUflash CeddyMod v1 (EcuFlash)

[Ceddy]

Highest resolution of ANY dsm ems? How would it compare to AEM EMS? Not doubting you, but this is really making me want to go find another ECU.

I'm pretty sure AEMs maps are 20x20. Don't know if AEMs Maps or Axis are rescalable.

The Ignition BigMaps is 22x26

Ced just wondering why my fuel and ignition big maps are coming out like this when I first load up the hex file.

Also i cannot edit any of the figures in "Ceddy Mods Setup Bits" or any of the "Periphery" menus by press "=" then entering a different value.

Thanks Ced, another donation will be coming your way.

**EDIT** Found I can edit Ceddy and Periphery by pressing the "[ and ]" keys. Still can't figure out why my maps are coming out like that. I have started from scratch and removed all old XML definition files the only one in there is the new 2055011.xml file

 

[wishnfor4g63T]

wow, i so wanna jump head first into this as my dsm recently is now my play car instead of a DD =)

i've never tuned anything i have a afc neo that hasn't been touched just plugged in.

the only problem is i believe my TPS doesn't work. On the neo it says 0.001 or something like that of volts. so would this software be able to work with that problem?

You have the stock size maps rom. Need the BigMaps Patch.
I can patch you existing rom, or send you a stock BigMaps rom.

I'll email you.

You can use the +,- keys for bits also.

No this won't work with a broken TPS, the stock ecu won't work with bad TPS either.

You might just have your SAFC hooked up wrong. Check your TPS using a logger.

Well guys all I have to say is wow. Just finished taking the car for a run with big maps and big timing, all ceddy mods turned on except

-Speed Density
-NLTS
-Base timing terminal

- knock sensitivity raised to evo 8 standards
-EGR and Purge functions disabled( I accidentally threw out my evap connector when i did my mods so it was thowing cel) now no cel whatsoever even with the connector unplugged.
-Rear O2 disabled
-Boost Limit raised to 250

Did a couple quick 1st, 2dn, 3rd, 4th pulls to around 5500 and wow the car is smooth as shit knock is gone, idle is smoother and quieter than before, launch control sounds sick and works perfectly. Boost control seems smoother(might be in my head), AFR's are mint.

If you are going to use this amazing software you should definitely donate something to Ceddy, I didn't even think I was going to be getting into tuning until I purchased a bigger turbo and fuel system down the road, along with AEM or LINK. Now I am getting experience and unbelievable control for a DD car. I give 4 stars 2 thumbs up and 100% to Ceddy, EvoScan, and ECUFlash.

Focker Out


**EDIT**

Oh yah, Mods, give this man some REP...

Any chance of support for passing readyness tests and the such

Explain a little more what you mean?

 

[jrohner]

He's talking about the emissions systems tests that show up in OBDII programs. Places that test for emissions require these tests not say "Failed".

 

[jeff24680]

I cannot verify that it will say not failed. However, like I mentioned my car was showing "Evap Purge Control Solenoid Error" in EvoScan as well as the CEL on the dashboard. Once I disabled the code using the periphery bits the CEL went away and when scanning for error codes using OBDII in EvoScan it comes up clean. There is a selection of codes you can do this for in the Periphery Section of CeddyMods using ECUFlash, including but not limited too: EGR, Rear O2 Sensor, Front O2 Sensor. All can be disabled if they are reporting errors. Once scanned they do not report the error again.


Ceddy could give more insight, I am just going on what I have done to my car.

 

[the_mork]

If you can convince Ceddy or someone else who disassembles to do the digging to find the readiness tests actually fixing it should be easy. Basically the readiness tests do their work and then point either to a memory address that has a bit that means fail or a bit that means passed, simply cutting out the entire test and having the "test" then simply point to a passed bit is how the evo ecu guys do it if that makes any sense.

 

[Ceddy]

The DTCs and Readyness Test are different things.
The Readyness Test are a series of test for emissions equipment, that some States check at inspection by plugging into the OBD2 port.

I most likely will handle this like the Evo guys do, and let someone non-US post the fixes for this kind of stuff.

 

[kawboy]

Sounds good! Perhaps the worst feature about link V.3 is no more Readyness (pass) hack!

 

[mike96]

i am not sure if there are specific years of Mitsubishi's this applies (might only be for the 96 - 97 ecu) to but i know when i first put my 96 Eclipse together with the stock ecu i had the battery disconnected, hooked it up then 10 min later had it over ar the emissions test place and passed. all readiness tests showed passed. the last time i went to an emissions center to get it tested i had been having a problem with the rear O2, all i did was disconnect the battery and take it in before the CEL came on and again it passed. after it passed i talked to the emissions guy about my car (fellow DSMr) having an EVO8 ecu in it and we got into a discussion about the readiness codes. apparently there is a known problem with the older Mitsubishi's that if you were to disconnect the battery and clear the ecu it will still show all the readiness codes as passed. unfortunately i don't know if this applies to the EVO8 ecu because i had already applied the patch to have everything show good. might be a good idea to have someone try it out to see if it applies to the 98 - 99 ecu as well.

 

[jrohner]

Usually the readiness tests will say that they are not complete if the battery has recently been disconnected or DTC's have been cleared recently.

 

[jeffo]

The default in the 1995 EPROM code is to set a value of E5 into the readiness tests upon cold boot, which sets all the applicable bits to "Not Completed". As Ceddy said, the fix for the Readiness Tests is a very easy patch, but the tricky part is releasing it without getting yourself into possible Federal emissions litigation. That is why the "official" DSMLink 2.5, and the new ECMLink v3, do not have the Readiness Test fix either. Just be patient. Eventually someone outside the US will post a patched ROM or the instructions on how to patch your own ROM.

 

[logic]

And yet, none of us over on the Evo side of the house are all that worried about the Feds raiding our top-secret headquarters (my spare bedroom) for our flagrant misuse of technology to bypass federal emissions standards.

I understand completely why Tom and Dave are nervous about it; they have a business to run. But we're all hobbyists.

Note that it was a U.S. DSMLink owner who originally made it possible to reset your readiness codes.

Only because people used a "diagnostic feature" for a purpose other than what it was intended for.

My big maps are jumbled too so it will still be ok using the small ones? How do I switch from norm to big maps? Does it automaticly run on the big ones if you use that rom?

BigMaps and the Stock Maps occupy the same space, you can have one or the other. There isn't enough physical space to have both. I have one XML with both the BigMaps and Stock Maps for the sake of simplicity, but you can only use one or the other.

The CeddyMods 1.81 ROM I posted is the Stock Maps, I have BigMaps as a patch, I run a patcher and it inserts the maps and code into your current ROM.

The patches make it easier me, so I can have one ROM, but have patches for BigMaps, SD, etc. Instead of trying to code a bunch of ROMs with different options and combinations of options.


Email me, and I can patch your ROM or send new one as an attachment.

your the shit ceddy

 

[logic]

Replying for acamus, since he's apparently not able to post here yet. (Can a mod do something for him, at least for this forum? I'll cheerfully vouch for him; if you spend any time at all over on EvoM's Ecuflash forum, you probably already know who he is. He's also the reason the Evo guys even have an OBD-II readiness patch.)

As Ceddy said, the fix for the Readiness Tests is a very easy patch, but the tricky part is releasing it without getting yourself into possible Federal emissions litigation.

Cool, I just wanted to make sure that i'm not on a jumbled fuel map. I don't feel the need to use the giant maps. Thank you though.

 

[the_mork]

If the option is available then I suggest using the bigmaps. I know when I switched to evo8 bigmaps I was able to smooth out a lot of my low speed driving and increase my high end resolution for overall shit grin results of improved driveability everywhere.

 

[GSXeclipsePSI]

My car is really hard to drive without spooling and pulling with the setup I have.
(3" no cat and fully ported FP E3B16G ported EvoIII 02, Large FMIC and EBC)

I can get 20-22psi @ 2800rpms. At 1/4 throttle I still start making 15psi @ 3000 and it just keeps trying to spool me up. Is it settings on the Profec? I have changed it to slow spool up down. If feels same on quicker and slower settings.

Like I have to shift it I can't just climb in RPM's (unless really slow and lightly).

I feel like I wish I had a regular car sometimes cause it gets annoying when I just wanna cruise but will the big maps help smooth that out?

I had a safc-II before and I don't know how the difference between AFC tune and a ECU tune will be for driveability can someone enlighten me? Or what I might want to do when I get to tuning the ECU w/ECUflash.

I know when I get my next turbo I won't be complaining bout quick spool up when I got a 60trim or more.

 

[jeffo]

The AFC tune works by simply removing some of the airflow signal to the ECU. Depending upon what size injectors you are compensating for, this can result in removing 30% or more of the Karman Hz signal from the MAS to the ECU. The problem is that the ECU also uses that signal to caluculate the load, which is used to scale the AFR and timing maps, so the ECU ends up picking maps that are much more aggressive. The 2G MAPS are very conservative, so if you have good 93 octane and smallish injectors, like 550's, leaning it out can be a good thing, because that extra timing advance will make the car feel much more responsive. It gets to be a problem though when you have larger injectors, or lower octane to work with.
The AFC can only control the AFR, not the timing advance directly, which is its biggest weakness. The big advantage to chip tuning, DSMLink, or flash tuning is that you can leave the airflow signal between the MAS and ECU alone, so the ECU stays on the proper maps. Then, ECUFlash gives you full access to both the AFR and timing maps, so you can tune them individually without causing any issues. Instead of effecting the AFR at all boost levels with an AFC, you can target just the cells at the boost level and rpm where it is needed. Its true 3D tuning.
