OK guys here it is:

car is EDM EVO9, stock rom ID si 88840016,has been get rid of maf instead of installing OMI 4 bar map sensor and GM IAT sensor.
first been I flashed tephta V7 88591715 in(map scaling and IAT scaling has been set up),car start fine, but now ater I changing some tephra mod like valet mod and ''periphery'' table,car wont start!!! even I fash the initial 88591715 rom in, still no go. I have search around thinging may be it is because of the Valet-mod locked the ECU, then I change the valet mod on(valet mod=1), ignition on,push the pedal make TPS=100%, valet mod start,the dtc light flash quikly,then I push the pedal again to trigger it off, the DTC light flashed slowly,I think I have been get rid of valet mod .then I change the valet mod in tephra mod table(valet mod=0 ),refalshed the rom to the ecu,car could been start but if I switch the key to off then restart the car, there's just cranking but not fire. at this time ,I have to flashed the stock rom yes 88840016 to the ecu then reflashed 88591715,the car could been started,also sometimes I use 88592715 instead of the stock rom. If I dont flashed an other rom but just reflashed the rom Ive been used now,still no fire.
In these process Ive realized when I began to flash a rom to ecu ,just after the "OK" have been clicked in ECUFLASH ,there is a sound like a ralay been triggered or switched uder the dashboard ,when rom updata is finished ,there is a close and sequential sound like ta.ta.ta...if this sound occured,this flashing is sucessful,the car could start,if not although ecuflash shows sucessfully but the car dont fire at all. Also there is another phenomenon I found if ecu runs stock rom,the M/Ttemp light will light up when ignition is ON,if tephra mod been run, the light never light up,but ''some times'' it will light up just with the noise Ive mentioned just now after like the some relay...but soon its gone with the ralay-trigger-noise ended.
now I can use stock rom, 88590715,88580014 with no start problems even pull out the key then restart, but as u no its neither a SD rom...

I ve been out of my mind, could find nothing...

I really wish some geekers here could help me ,tell me what happened to the ECU or my car and what shall I do ...

There's a sd2.0 aka 3dsd rom available for 8858. Also I think tere is a 8857 sd rom available too. You'll have to search and ask around but they're out there.

No I mean for 8858. I've been through the process of switching between 8858-8859 never had any issues.

at the beginning , I have not any issue either. just after messed up some mod , car or another saying ecu became crazy.
so I wonder no what happened, even I flashed the initial 8859 rom seems still no joy!
