NefMoto

Hi, all
Thank you very much for this NEFMOTO tool because I could flash a ECU at the first time with 180HP!!!

I have two questions. 1: The checksum of this bin file was "compatible". Does it means this edu CAN not have any checksum forever, if I do not make a mistake to edit??? When I stop to flash this ecu and I go on using this car, maybe after a year/day, could I have the checksum error??? Once the checksum is checked as "compatible", don't I need any scare of stopping engine because of checksum itself???

2: VW1.8T 150hp engine as stage 1, how much HP as maximum can one get only with ECU flashing??

Thanks!

I could get 180HP @4200rpm, if my calculation is right.
Today, Japan has now a typhoon and it is raining, then I could not drive more faster.

It will probably be fine. There are some cases with errors popping up later, but normally, if it works, it stays working.

2: VW1.8T 150hp engine as stage 1, how much HP as maximum can one get only with ECU flashing??

Around 200bhp

Thank you so much for giving answer!

I could not start this engine after this test. By writing ECU, Nefmoto said to me that ECU will be reset.
I kept the engine idling in ten minutes and started as test in this time... I have also VCDS. How can I recover this???
This is also the first time to reset ECU for me. I am confused by many factors(Checksum,Reseting ECU,my tuning)..

I didnt fully understand your last post, sorry.

- Does your car starting?

- Does vcds connect?

- Do you have any fault codes?

- What flash file did you write?

Hi turboat!

- Does your car starting?
= NO.
- Does vcds connect?
= YES, but I can not see the engine section.
- Do you have any fault codes?
= Please see the VCDS's log below.
- What flash file did you write?
= My new tuned file. This is made from original bin file by Tunerpro. The ME7 Checksum plug-in told me "compatible".

I could not connect to ECU with mormal mode of NEFMOTO :'(, and should I choose boot mode to flash the original file back?

Boot mode option in nefmoto software does not work it was never finished. You can write your original back over obd2 as long as you can still connect to the ecu (as long as its not bricked) What definition file are you using?

Thanks, Marty.

I could not connect to ECU as boot mode, too. Now.. I can connect only by VCDS, but not to engine ECU..

I wrote my 032JR xdf file that I made and analyzed tempolary from 032HN and 032RD. This tuned bin file  is "compatible"..

Unfortunately if you can't connect to the ecu your bricked your ecu is inside your dash time to pull it out, open it up and reflashed it I made a how to vid
http://youtu.be/iY7w-2owzck. Did you make your own definition? Or did you use another one ? Did you switch software versions?

!!!!  switch software versions!!!  What !?  I had to change the "software version" of ECU?

I did make my OWN xdf file. I changed all table and data at first, but I found I need to work axis data as next step.
For my first tuning, I worked only with the axis of BOOST and TIMING tables for XDF file because I had no time to complete this xdf file. I did not finish the other axis, but I made my first bin file, because ECU do not refer xdf file itself, i think.

I didn't want to pull out ECU from car. Can I recover this ECU also with "Galletto 1260 flashing cable"?

But strongly I want to know why this ECU would be a "brick" ;D Oh, my god.. I think I didn't make a mistake to make xdf, I hope.
 

I can see "boot mode" in nefmoto software, but the Galletto 1260 Flashing Cable uses a more lower level's boot mode?
Can I understand there are many levels of boot mode?

Thank you!!

did you correct the checksums after you edited your file? If not that would be the reason for the brick. Unfortunately you will still need to remove the ecu to recover it. You'll have to ground pin 24 for 5 seconds on power up to start boot mode, and yes galletto 1260 will work for this

1 boot mode only
Bootmode in nefmoto does NOT work, it was never finished

Hi, Marty.

I've ordered MPPS and now i decided to make boot mode as your video, Thanks!
Do I have to connect +12V to all three pins(3,21,62) and the ground to 2 pins (1,2) as follows ??
http://wiki.obdtuning.com/images/a/ac/VAG_ME7.x.jpg

After I edited my file, the tunerpro said my bin file was "compatible" on saving my bin file.
And I want to ask about software again. But I have something to say a likely reason of "bricked".
When I have flashed my bin file with Nefmoto, I opened and closed the door of vehicle.
I've just read someone said that the door shall be opened/closed on flashing ECU with MPPS. ???

I could finally connect to my ECU with MPPS(chinese copy?) in boot mode!! Thank you, all.

I can read ECU, but can not save this file and writing also is not possible.
I tried it with 2 different windows xp sp3.(japanese lang).

My Questions are :
 How do I resolve this software problem?
 Can I use this "MPPS V13.02 Cable" with MPPS V12 software??

I am thinking to buy Galletto 1260.

Thank you very much!

Thank you, I finally wrote my original bin file in boot mode. I can run my car again!
I have done it with MPPS somehow, but I did not understand this things exactly. (I bought also Galletto but it won't work.)

I try to write new bin with NEFMOTO, but I got the message "Precondition not met: Immobilizer Not Authenticated" in NEFMOTO.
I understood this because my ECU have experienced BOOT MODE.
This means I can not flash again with NEFMOTO? Or Must I put BOOT MODE again with MPPS, if I want to write bin to my ECU?

Now I can not connect to MPPS. Does it mean my ECU is not in BOOT MODE?

Sorry for my cheap understanding. But I am happy for such following new pages :)
http://nefariousmotorsports.com/forum/index.php?topic=6537.0title=

I write that I got from NEFMOTO, as follows:
Slow init succeeded.
Switching to KWP2000 session.
Connected
Disabling Windows sleep mode.
Writing ECU flash memory.
ECU reports programming session preconditions have not been met.
Reasons preconditions failed:
-Immobilizer not authenticated
Continuing despite programming session preconditions not being met.
Negotiating communication timings.
Successfully changed to new communication timings.
Requesting security access.
ECU reports that security access request was rejected.
Starting diagnostic session.
Unable to properly start diagnostic session, attempting to continue with current undefined session.
This can occur if the security lockout is running, or the engine is running. Please turn off the ignition and retry if this continues to fail.
Negotiating communication timings.
Too many consecutive unsolicited messages from ECU, disconnecting.
Disconnecting...
Disconnecting because no response was received for the Stop Communication message.
Disconnected
Writing ECU flash memory failed.
100% complete.
Restoring Windows sleep mode.

So, you've edited your original file?  The 032JR?

What did you change, and why?  Always, always, always do fueling first.  Have you read the wiki?

Once you've edited your file, you saved it, corrected the checksums and then flashed it, correct?

It sounds like you've bricked your ECU, so it's going to need to come OUT of the car, so you can get it on the bench and bootmode it.  You cannot bootmode in the car over the OBD port (yes, I understand you can, but for easy and noobyness clearly shown here), take it on a bench.

Once in bootmode, flash the ORIGINAL file back on - uneditted, whatever you wanna call it, and get the car to start.

Post the file you flashed so we can check it.

Then, read the wiki, and start with one step at a time.

Thank you very much, adam-!

I did flash BEFORE checksum.. Then I made boot mode and rewrote my original bin file with mpps.
For me, my mistake seems to gone, but now I know that Nefmoto can not work with my ECU, again.

I did finish checksum, and I want to retry flashing with it, but Nefmoto won't work.
Then I ask ,,, should I put my ECU into boot mode AGAIN? Maybe immi-things is difficult for me...

I have just fear to boot mode, because I tried to recover my ECU many time with MPPS&Galetto...

I could re-flashed with MPPS. It was just MPPS won't recognize and start SOMEHOW...
My clone MPPS and Galetto 1260 can not work always... it was very bad PC things... I must try to connect many times.

After my first tune, I can not connect to ECU with VCDS. Maybe because of experience of boot mode..?

If the ecu was programmed correctly with a valid bin, vcds would work. How you program it has no effect on if vcds will work.

You need to checksum before you flash, not after.

Once it's flashed with a good bin, and the car starts, you should be able to write and connect with VCDS.

I don't want to sound patronising - but you know you need to ground out a pin to get into bootmode?

I see. This is grateful advice, thank you very much!
My file would be OK because MPPS clone corrected my file.

Now I must check the CAN connection to vcds again.
I get now message "K1: Short to Ground , K2: Short to Ground" in connection test with many drivers.
But it would be just USB drivers that I had many difficulties :-*

I did not know that :'(  My english is not well but I did.
For boot mode, I did 24pin to ground with 15V.

Now my car can run with power. It is OK but my understanding is very limited..
I know I must learn more..
