I'm getting my to do list for this summer for my mistress. Amongst these jobs are finishing sound proofing the floor, painting the rest of the trim, fixing the power steering pump leak, etc. But I have two I have questions on, before I proceed, from a more experienced crowd. First issue that I'm seeking advice on is tuning. I have a 94 base, with a 91 Jdm motor, harness, and ecu in it. Just finished getting it in and running smoothly before the bad weather last fall, and at the time, it was running smoothly, and thanks to ccrunner, we got it tuned properly as well. But now as the weather is warming up, I'm still getting white "smoke" in my exhaust. It doesn't smell sweet, and I've been checking my oil and coolant levels all winter. Neither have changed. The only other thing I can think of is unburnt fuel? That would coincide with my fuel economy dropping, which I have begun to notice more and more. Recommendations? Should I just get an aftermarket fpr? I do have a wideband a/f gauge in the rear bank precat, and a single O2 sensor in the downpipe, which is where the ecu is getting its signal. Should I try a reset first? The Af gauge is registering ~14 at idle.
Next is the radiator fans. I wired them to always be on, and swapped out the larger passenger side fan for another of the smaller driver side ones. The hot-wire worked great on the driver side, but I still can't get the passenger side fan tied into the ignition circuit via the hi or lo relay. I'd like to keep the residing in the junction box to a minimum, so I was curious if someone has already done this, and could pass along how they did it? Also, related to the coolant temp, my prosport coolant temp gauge is registering ~20 degrees higher than my datalogger. Which should I believe? To the best of my knowledge, the ecu temp sensor has never been replaced, but I know that prosport gauges can have this tendency based on luck of the draw. Anyone got recommendations on that as well? Thanks for all you help in advance!
