80LS1T Posted March 13, 2003 Share Posted March 13, 2003 Ok I have a 93 LT1 and I know that it originally came with a 2 connector harness on the coil(right?) Here's the deal... I bought my harness from the notorious Darius when he upgraded to a stand alone system and I bought the computer too. Now I know he bought the harness from Street and Performance. What I don't know is what kinda of coil connector I have??? Can someone show me a pic of a 2 connector harness and a 1 connector harness? Also why does the harness have 2 O2 sensor wires? The original didnt? Should I put a second O2 sesnsor in? Also what goes into the programming of the chip? I know the chip thats's in the computer now has all the VATS and emmisions deleted but would it also be programmed for a supercharged LT1 since thats what his car was?

Guest Anonymous Posted March 13, 2003 Share Posted March 13, 2003 The 93 has 2 o2 sensors. One for each cylinder bank. Yes you need them both. You also need a wiring schematic of the 93 computer. Someone will chime in with a link to it I'm sure. The schematic will also answer your questions about the wiring harness. If it's a street and performance harness, just give those guys a call. They are very knowledgable and can also reprogram your chip to get rid of the emissions and VATS. Good luck, Mark Quote Link to comment Share on other sites More sharing options...
80LS1T Posted March 13, 2003 Author Share Posted March 13, 2003 Yeah I might just have to do that. I was just wondering if anybody had a pic of each of the different connections? What about the chip? Is there fuel maps and stuff like that programmed onto the chip? Cause if I dont need a chip then that will save me $200. I just know that the VATS & EMMISIONS is not on the chip that is in the computer now. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 14, 2003 Share Posted March 14, 2003 If the Vats and emissions are already taken off the chip, then run the car on that chip and see how it does. Did you get the chip from Darius also? Was is set up to run the car with boost? If so this might be a problem. I think S&P charges baout 100 to burn a new chip.

80LS1T Posted March 14, 2003 Author Share Posted March 14, 2003 Yeah it should be set up for boost. I think S&S charges like $200 to burn a chip! And I am pretty sure that I have a 2 connector coil set up. Do all the LT1's have 2 knock sensors? Cause this harness has 2 connectors! Also you said that the 93 had 2 o2 sensors, right? Well where did the second one plug into the exhaust? There is a spot for one of them in one of the manifolds but not in the other??? Should I just put one in just below were the manifold connects to the rest of the exhaust system? So it wouldnt be in the manifold but it would be as close as possible. Thanks, Guy Oh yeah and I am starting the reassembley of my engine next week!!!!!! And I am getting my heads and intake back from porting and polishing/port matching intake/head rebuild!!!! To say the least this is a good week comming up! Quote Link to comment Share on other sites More sharing options...
