  1. My business partner, electronics design/consultant, decided to get a RX7 , silver colour back in 1980s. Though I only drove it for about a week, and a few short pickup materials/components trips later, it was quite interesting to drive. Very smooth and responsive. As a car it handled ok, but only having it a short time never got 100% adjusted to it. My own vehicle was a short wheelbase Nissan Patrol 3.3L Diesel, so entirely different feel. My normal weekly job was with Bosch doing fuel injection system design and responsible for injection system calibration, drivability, fuel economy and emission conformance, sadly on sedan 6 Cyl Holden and Ford cars. But as part of training in Germany I had driven many different cars, including Porsche, Saab turbo, Alpha, Fiat, VW, Opel, BMW including sedans and sports cars galore. Even a trip in a Lamborgini, sadly only a warm-up drive at slower speeds. So did have wide experience of different cars. But realistically, to really judge a car you need a few weeks on varied conditions to truely evaluate a vehicle fully. Else it is only test drive first impressions. To really put a car through extreme performance needs time under severe conditions and becoming one with the car. Not possible in daily city traffic and city roads, even freeway is barely letting you fully go, unless you care to lose your license or at least a few tickets. The RX7 did well and surpassed the Fiat and Alpha sports cars, but fell short compared to Saab Turbo and Porsche cars. Well ahead of most standard sedans. One of my daily work colleagues was most impressed and envious, another was a die-hard Alpha car nut, with half rally propped car, who liked the responsive rotary, though down on power of his road legal, semi rally setup Alpha. By the way my business partner drove it for near 15 years, and other than failing radiator and some AC issues, no engine problems. Finally the roof liner was falling off, rear windows started some water leakage and some stone, sand, gravel marks of paint work he upgraded to a car. Worst that happened his wife reversed back out if the garage with door partly open folding it forwards fully, as the crunch caused her to hit fully accelerator, instead of brake. Got repaired, but she also got a few parking dingo and marks on the bumpers.

  2. Talking car tuning, as I started my engineering degree course I had a free afternoon from lectures so popped into my dad's petrol station and car workshop. Fortunate as dad was very busy that day and the mechanic reported sick, but also a young guy with a little bit hotted up car had booked for a Electronic tune up that already the week before had to be cancelled as the workshop was filled by a broken down, part stripped down car. So dad was worried, and asked if I could have a go at tuning the car. The electronic equipment I was not concerned about having previously read the manuals, even clarifying so matters to both dad and the mechanic. We only had the equipment for a bit over a couple of months and dad had trained for three days, to be allowed to advertise the tuning service. However I had NO tuning experience, but had a go, went through all the ignition checks, timing, fuel/carburettor setting for mixture vs tail pipe CO, HC and NOx. Fitted new spark plugs sadly (fortunately?) The ones I found in stock fitting that car were double gap which might account for some of the result. I finished the best I could do, but was concerned that idle was a bit high, and unsteady. But it seemed to drive OK. On pickup, we told the young customer that sadly the mechanic was absent so if anything was unsatisfactory to come back and the mechanic would do it again, or a full refund was available. WELL SURPRISE! The young guy was back the following day, beaming ear to ear, praising the terrific performance change to his car it ran to perfection as far as he was concerned. He said it never ran so well before. In the following months a number of his mates got electronic tune ups done, most however were not as impressed, though all quite satisfied, except one who had the mechanic redo it, I pocked around it too and the customer was pleased to get some improvements. None ever got a rough idle or major performance boost. Some reported fuel economy gain, and smother driving. I suspect I had mis timed to higher advance and may have left mixture a bit richer at high throttle. I certainly had spark gaps longer than intended, as I made a mistake on the feeler gauge setting the gap as well that they were double gap type, listed by manufacturer optional/suited to that car engine, so not wrong in that aspect.
