I programmed my ECU today. I modified it because I wanted pops&bangs.
The car did not start after uploading. The entire program has been loaded.
Luckily, I was able to upload the ori file. Does anyone know what the problem is.
I use mps. Audi tt 1.8t 98.

if it can help...
ME7Sum (v1.1.2) [Management tool for Bosch ME7.x firmwares]
Inspiration from Andy Whittaker's tools and information.
Written by 360trev and nyet [BSD License Open Source].

Attempting to open firmware file 'POPS8N0906018AB.bin'

Step #1: Reading ROM info ..
 Searching for EPK signature...OK
 Searching for ECUID table...OK
 EPK         : '36/1/ME7.5/5/4019.00//F19u3/Dst02o///'
 Part Number : '8N0906018AB '
 Engine ID   : '1.8L R4/5VT         '
 SW Version  : '0002'
 HW Number   : '0261207027'
 SW Number   : '1037354503'

Step #2: Reading ROMSYS ..
 Startup section: word[0x008000]+word[0x00FFFE]
 @08038 Add=0x0000E5B3 CalcAdd=0x0000E5B3  ADD OK
 All param page: word[0x010000]+word[0x01FFFE]
 @01a896 Add=0x00971D CalcAdd=0x00971D  ADD OK

Step #3: Finding CRC table(s) ..
 Searching for CRC table(s)...OK
 CRC table(s) OK

Step #4: Reading RSA signatures ..
 Searching for RSA offset #0...missing
 Searching for RSA offset #1...missing

Step #5: Reading Main Data CRC/Checksums ..
 Searching for main data CRC pre block...missing
 Searching for main data CRC/csum blocks...missing
 Falling back to default 512k CRC blocks...OK
 Searching for main data CRC offsets...OK
 Searching for main data checksum offsets...missing
 Main CRCs:
 1) 0x010000-0x013FFF @6693c CRC: 03AA9D3E CalcCRC: 03AA9D3E    CRC
 2) 0x014300-0x017F67 @66942 CRC: 9FBCA63F CalcCRC: 9FBCA63F    CRC
 3) 0x018191-0x01FBFF @66948 CRC: 42380CD2 CalcCRC: 42380CD2    CRC

Step #6: ROMSYS Program Pages
 Program pages: 8k page first+last in 0x0000-0xFFFF and 0x20000-0x7
 @00803c Add=0x41CD80 CalcAdd=0x41CD80  ADD OK

Step #7: Reading Main Program Checksums ..
 Searching for main program checksum..OK
 ROM Checksum Block Offset Table @1bfcc [16 bytes]:
 1) 0x000000-0x00FBFF CalcChk: 499CCE49
    0x00FC00-0x01FFFF CalcChk: 3D3CD6F6 CalcCRC: DCEE4698 SKIPPED
 2) 0x020000-0x07FFFF CalcChk: F9DF09E3
 @7ffe0 Chk: F9DF09E3 CalcChk: F9DF09E3 OK (i)

Step #8: Reading Multipoint Checksum Blocks ..
 Searching for multipoint block descriptor #1...OK
 1) <14224>  0x024000-0x026567 Chk: 0AE61FD2 CalcChk: 0AE61FD2 OK
 2) <14234>  0x014000-0x014243 Chk: 005FB53E CalcChk: 005FB53E OK (
 3) <14244>  0xFFFFFFFF-0xFFFFFFFF  END
 Multipoint #1: [2 blocks x <16> = 32 bytes]
 Searching for multipoint block descriptor #2...OK
 1) <1fc00>  0x000000-0x003FFF Chk: 0FA0F5CF Boot: (whitelisted) OK
 2) <1fc10>  0x004000-0x007FFF Chk: 0F4716B3 Boot: (whitelisted) OK
 3) <1fc20>  0x000000-0x003FFF Chk: 0FA0F5CF CalcChk: 0FA0F5CF OK
 ..........
 Multipoint #2: [34 blocks x <16> = 544 bytes]

Step #9: Looking for rechecks ..

*** Found 41 checksums in POPS8N0906018AB.bin

*** DONE! 0 error(s) in POPS8N0906018AB.bin! ***

Thanks for the help.
The error was in mpps.
Pops work but too hard for me.
