>hey dude....a 727 is the same ecu used in 90-91 vettes.....its called a weatherpak....is suposed to be pretty much heat and rain resistent....if you change the memcal to a v-8 one for a 80-91 vette or 91-92 tpi camero it should work....this is for a speed density set up and does not use the maf type setup....it runs off the map sensor...it also must have a 4000 ppm vss....chris in north jer z                                                               From: Joe Boucher <boucherj at prodigy.net>
