Did you bother reading the sticky?

http://nefariousmotorsports.com/forum/index.php?topic=3346.0title=

Also, winols should correct it for you properly. If it does not, you need an updated version of WinOLS.

If you are using a pirated version... read the sticky Tongue

if I read several issues, everything works apparently corrects me the checksum, the problem that apparently leaves the original again, meaning any changes you make to work the launch control disappear.

The car turns and gives me a checksum error, the problem that maps the original leaves.

Yes, but the archive .bin generate for me7sum not change values.

Step #1: Reading ROM info ..
 Searching for EPK signature...OK
 Searching for ECUID table...OK
 EPK         : '42/1/ME7.5/120/4518.KF//24C/DstS5o/300403/'
 Part Number : '06A906032QA '
 Engine ID   : '1.8l 5VT NB MT  '
 SW Version  : '5268'
 HW Number   : '0261208216'
 SW Number   : '1037368320'

Step #2: Reading ROMSYS ..
 Startup section: word[0x008000]+word[0x00FFFE]
 @008038 Add=0x006433 CalcAdd=0x006433  ADD OK
 Program pages: 8k page first+last in 0x0000-0xFFFF and 0x20000-0xFFFFF
 @00803c Add=0x98A702 CalcAdd=0x98A702  ADD OK
 All param page: word[0x010000]+word[0x01FFFE]
 @01beca Add=0x00971D CalcAdd=0x00971D  ADD OK

Step #3: Reading RSA signatures ..
 Searching for RSA offset #0...OK
 Searching for RSA offset #1...OK
         Signature: @9b5e6-9b666
           Modulus: @16ad8-16b58
          Exponent: @16b58 = 3
 Searching for MD5 ranges...OK
 MD5 Block Offset Table @16ab4 [32 bytes]:
 1) 0x00010002-0x00013FFE
 2) 0x00014252-0x00017F4E
 3) 0x00018192-0x0001FBDC
 4) 0x00026A00-0x0002FFFC
 EncrMD5: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
 CalcMD5: 2c 39 20 78 25 04 e9 2f 14 f0 40 86 1c 38 8d 5b
 ** FIXED **

Step #4: Finding CRC table(s) ..
 Searching for CRC table(s)...OK
 CRC table(s) OK

Step #5: Reading Main Data Checksums ..
 Searching for main data CRC pre block...missing
 Searching for main data CRC/csum blocks...OK
 Searching for main data CRC offsets...missing
 Searching for main data checksum offsets...OK
 Main Checksums:
 1) 0x010002-0x013FFE CalcCSM: 0013320A
 2) 0x014252-0x017F4E CalcCSM: 002D2991
 3) 0x018192-0x01FBDC CalcCSM: 004A4BE1
 4) 0x026A00-0x02FFFC CalcCSM: 00BCDB4E
 @9be2c CSM: 00BCD88D CalcCSM: 00BCDB4E ** FIXED **

Step #6: Reading Main Program Checksums ..
 Searching for main program checksum..OK
 ROM Checksum Block Offset Table @27c50 [16 bytes]:
 1) 0x000000-0x00FBFF CalcChk: 48CFC240
    0x00FC00-0x01FFFF CalcChk: 23E18BF9 CalcCRC: 1FC3E5BC SKIPPED
 2) 0x020000-0x0FFFFF
    <fffe0>  Chk: 0ECF69D7 CalcChk: 0ED340E4 ** FIXED **

Step #7: Reading Multipoint Checksum Blocks ..
 Searching for multipoint block descriptor #1...missing
 Searching for multipoint block descriptor #2...OK
 1) <1fbde>  0x000000-0x003FFF Chk: 0FA0F5CF Boot: (whitelisted) OK
 2) <1fbee>  0x004000-0x007FFF Chk: 0F4716B3 Boot: (whitelisted) OK
 3) <1fbfe>  0x000000-0x003FFF Chk: 0FA0F5CF CalcChk: 0FA0F5CF OK
 4) <1fc0e>  0x004000-0x007FFF Chk: 0F4716B3 CalcChk: 0F4716B3 OK
 Multipoint #2: [66 blocks x <16> = 1056 bytes]

*** Found 70 checksums in launch1.bin

Attempting to output corrected firmware file 'Correctchks.bin'
Ý Opening 'Correctchks.bin' file for writing
Ý Writing to file
Ý Validating size correct 1048576=1048576

Have you looked at all the files with a hex editor?

Did the launchcontrol changes put changes in an area where there is a checksum?
