New Problems
Ok i just recently went ahead and got another ecu just to see if it will clear the ks codes off the ecu, which was code 52&55 because the mechanic told me they fix both knock sensor signal problems and put new ones in, but the ecu still kept showing the codes on my 94 sc400. Then today i went ahead and put in the new ecu, and i didnt see the knock sensor codes pop up(thank goodness), but now a new code came up which is cel code 71 that was not on the old ecu, maybe old ecu was fried and could not show that one, and also my overdrive light now blinks now, which is a code 38 that i cant find no information on if its related to transmission, thankyou for reading.

update
I may need to look up the cleaning up the egr system, or deleting the whole dam thing. Maybe my old ecu was just not showing this problem because it was screwed up. Doesnt stop the fact my overdrive keeps blinking a code 38
