Narrative:
On takeoff on runway 8 above 80 KTS; but below V1; we got an overtemp on engine #1 by about 3-4 degrees. I called for the abort and taxied off the runway. I informed ATC/company/flight attendant and passenger of the situation. I called our maintenance control and our dispatch to tell them what had occurred. Maintenance had me reset our takeoff setting and then do a full power run-up. No overtemp on engines was observed. They then had me reset the fadec breakers and also de-pwred and re-pwred the aircraft to clear the message on the EICAS. Then they told us we were good to go and attempted the takeoff again. On the second attempt; the engine #1 overtemp'ed again. We aborted and returned to gate. We took another aircraft back to base later that night while maintenance worked on the aircraft. I was contacted the next day by my supervisor; informing me that I might have violated an far by doing the second takeoff attempt. We had run all checklists for this problem and contacted maintenance control as per the checklist; and after following their instructions; doing a successful run-up and being told we were 'good to go' I felt we had done everything right. Also felt we were not doing anything unsafe. If in fact this was wrong; then not sure why maintenance told us it was ok.
