ECM upgrade (1227730) for stock 2.8 (Page 92/107) Darth Fiero AUG 28, 01:17 AM quote Originally posted by mtownfiero: I got my a/c sensor today and as i was checking out how it went on and i can visualize the two o ring idea now i was wondering would using teflon tape on the threads help seal it up even better? I dont know if it will work right or not but im assuming it would. Teflon tape won't do anything. These are not pipe threads. The o-ring does the sealing. carnut122 SEP 09, 06:19 PM quote Originally posted by americasfuture2k: this guy deserves an open bar. great man. and some hooters ladies I think he'd be alright with the open bar and Hooters ladies, but I'm hoping he doesn't want the great man! Brint SEP 28, 09:01 PM GOT to be one of THE BEST engine performance upgrades I've done to my "mostly stock" 87GT 2.8! Five months now, and NO problems (except one of my own wiring mistakes which was very easily fixed) Ryan, just wanted to say Thank You, again. americasfuture2k SEP 29, 11:15 AM quote Originally posted by carnut122: I think he'd be alright with the open bar and Hooters ladies, but I'm hoping he doesn't want the great man! lmao OH10fiero OCT 21, 02:14 PM Do you know off hand if this ECM will work on a 2002 N*? I know they made changes on the DIS but not sure what the exact changes were. If there is specific info you require to answer the question I would be more than happy to research it. Blacktree OCT 22, 10:21 PM I don't remember if this was covered or not, but can the 7730 ECM be programmed to control a heated O2 sensor? Due to the long-tube headers and a slightly rich AFR, my ECM is spending a lot of time in open-loop mode.

Due to the long-tube headers and a slightly rich AFR, my ECM is spending a lot of time in open-loop mode. The 7730 will not actually control a heated O2 sensor. But it will work with one. If you install a heated O2 sensor, you will need to wire up the O2 sensor's heater circuit to switched power and ground. -ryan Blacktree OCT 24, 12:47 PM OK, thanks. I've read a couple DIY projects where they spliced the heating element into the fuel pump circuit. So I'll probably just do that.

So I'll probably just do that. I wouldn't. Just wire it up to an existing 12v + switched IGN power source such as the backup lights power feed or the EGR solenoid power feed. This way you can turn the key on and let the O2 sensor pre-heat before you start the engine which can aid in cold startup fuel tuning. -ryan Rhino506 NOV 06, 10:06 PM I just had Ryan do this same conversion for me (the 4t440 and 7730) and it was well worth it. The engine just seems to run much better now, and the transmission swap is great. I had a 3.33 rebuilt, and am very pleased. The acceleration doesn't seem to be hampered at all, and I am turning about 2200 rpm at 75mph! Much better than the 3300 before! I'll have some fuel economy numbers after a trip to the Colts game this weekend! I would highly recommend this to anyone thinking about it. The two combined really make the car feel more modern and enhance driveability!
