Hey guys, I'm working on the 92 in my sig and don't have a tweecer for this one, yet. I just got the car back together and I'm running a 3" Pro-M blow thru for the ATI setup that was calibrated for 42's. I am tring to run it N/A for now while the blower is getting upgraded. I tried to start it this weekend but it stinks. In the beginning while in OL, the car will just surge up and down until it dies. If I help it wil the throttle long enough to get into closed loop it will idle somewhat. TPS is a .98, vaccum is reading 14in when it settles down. I had to lower the FP down to 29-30 with NO vaccum (24 with) just to get the thing to stop popping and stop blowing smoke, can you say RICH!
I hooked up my tweecer with a stock A9L been just to see what the LAMBSE were ect... Even at this low FP (which I know is bad) the LAMBSE is pegged at 18.3 meaning the EEC is trying to lean it out as much as possible but can't lean it enough, still too rich. I took it around the block like this and once it gets more air (above 2000 rpm's) the LAMBSE comes down to about 15.9, so still rich.
My question is how should I attack this. I was thinking about by-passing the T-rex that is inline to see if it helps, but I don't think thats going to be it. I've got to bring my base FP back up to 39, but it runs WAY too rich at that FP. What else can I do?
