1202 ALARM

I was in Maplin's looking for miniature spade terminals and saw they had a sale on solar panels, must have been the recent sunny weather I guess. Anyway they had a big 2.4 watt one at £25 and smaller 1.5 watt ones for a tenner. Now, thinks I, two 1.5 watt panels makes 3 watts for £20, which is better value for money and I already know that solar panels can be quite merrily connected in parallel. So I bought 2 of the smaller ones to use to trickle charge the car and back-up batteries.

Well, I'm going to try and link up some of my interests by going for broke on an automotive project. The plan (!) is to make a more advanced version of Rob Files' famous 'Grunt Box' for the MK1 MR2 Supercharger, which overcomes a known issue with a lean spot at low RPM and high throttle. Rob's clever workaround was to use the cold start injector to squirt a little extra fuel into the engine in this condition and give it some grunt. The Grunt Box is expensive and seems to be an analogue circuit (nothing wrong with that), but I fancy a bit of PIC shenanigans. My system will give some fuel boosting and go a bit further by providing a dashboard display of 8 of the most useful engine parameters as detailed below. I would like to use a PIC16F690 running at 20MHz to do this and connect the display via RS232, but I might go mad and use an entire computer at the dash end (P1 75MHz laptop motherboard) with a 6.5" video display as basically a terminal Sensors 1 - Thro

It hasn't been MOT'd in three years... It's only travelled 300 miles in the last six years... It's got twin cams, 16 valves, fuel injection and a supercharger... It's mid-engined and rear-wheel drive... It's only got 2 seats... It's got lowered suspension and adjustable shocks... It has tricked-out engine management... It can do 0-60 in 5.5 seconds... They thought it was dead... They were wrong.
