Default Need Help with Utec on Wrx 02

Hi, i just bought it used from a member of this forum and it had some custom maps and parameters, hooked it up as it was sent to me and start the engine it started fine, but after a minute there was gas smell so i figured it could be from those unknown maps so i shut it off, downloaded stg 3 map and parameters from TXS and uploaded to the utec, it all went well so i started the engine again, rev it a little and it was hesitating at about 2.5k-3k, let the engine warm and still hesitate. at this point i thought maybe other maps from previous user in there where messing this thing up so i deleted everything and reloaded stg3 on slot 1 left the others blank and tried again. this time hesitation went away but then theres this strange noise like rapid knocks when i press the gas slightly from 1k and then it revs normal, no cel flash while this occur. took it for a short gentle drive with laptop hooked logging, it runs fine, no hesitation or knock present, came back home and idle became erratically low for a minute cel was steady on and then back to normal, cell shut off but noise still present. Did this even with the selector on 0. Unhooked the utec and left oem ecu, cranked the engine and all symptoms are gone.

Sorry for the long post but is it possible any setting remains from previous tuner that could be messing this thing up? should i flash it with a fresh firmware and start again? please help.

i guess i was mistaken, the only way to reset the settings is to upload a map or just 'know' what the default settings are or maybe reinstall the firmware.

i noticed in your mod list you have an EBC... so your stock solenoid is disconnected, right?

have you checked the utec's grounding cable?

Stock Solenoid is disconnected yes, EBC was working fine after UTEC. Ground Cable was attached to a bolt which has another ground cable from car near the kick panel, i dont know if thats a good spot. Ill upgrade the firmware from 5.0 to 5.8 this weekend, ive read much about people with weird problems like me and cleared them with a new firmware.

I resolved the issue by reflashing Utec's firmware and uploading maps and parameters again... thanks for the replys
