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.

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 Cry, 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" Grin 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

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. Huh

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!
