  1. Thanks for the write up Peter. Sorry it's taken me so many months to log into the forums. This year hasn't been the smoothest. Looks like the HID is better for real world driving visibility, out at distance. A bit hard to compare the wet vs dry tarmac. Dry kicks back so much more light than wet. Cheers
  2. It's worth noticing that the Pioneer units are resistive touch (i.e. single finger presses into the surface slightly, and scrolling/dragging is hard) whereas the Alpine CarPlay units are multi-touch capacitative like a smartphone/tablet screen. Worth trying one of each before committing that much cash. I'm beginning to consider a solution like the Alpine iLX-F903D, with its 9", non folding but posable screen.
  3. Does look like Scarlet. That Sakhir Orange looks much better on it than most BMWs

    Exige picture & video thread

    ... apart from the Nürburgring Combined Circuit. Looks great though. That's going to be taxing to learn. Nice that it's so compact for incident handling.

    Exige Sport 350 in Mugello and Imola 2018

    Both tracks look great fun and the Exige is making a decent account of itself. BTW, do you know that you're holding lock all the way to corner exit rather than blending into the throttle? I know it's something I've worked on and so I kept noticing it in both vids. It doesn't seem to be losing you a huge amount, but might be something to bear in mind.

    LOL! Weigh yourself with and without the panel and subtract the two. Just sayin' Love those aero catches
  7. Hi Phil I'll give this a go. Let me say you are asking fairly reasonable, technical questions but are skirting the edge of overthinking it The response curves of the speakers are theoretical and will vary substantially once housed in the car. The graphs/numbers are probably based on an idealized scenario. IRL they will tend to have odd resonant behaviour that means you will end up tuning by ear to some extent. I got myself a plug in reference mic for the iPad which is helpful in smoothing out the crossover from sub to fronts, particularly, adapting the sub parameters to the front speakers and avoiding big resonances in the foot well. I use SpectrumView, but any spectrum analyser app will generally do, and you can probably use the built in mic at least for finding odd booms and spikes. Your approach is sound, cut over at 80Hz, i.e. as low as you can match, and I'd pick a reasonably soft roll off, so that you don't get obvious transitions on sweeps. So if you intend to use the crossover features of the H/U, I'd use 6dB/octave. HTH Martyn

    @Sport220 Good grief! Full tilt round Monza. Helmet strap hanging loose. What could go wrong?

    Reminds me of this, around 0:50... Dictionary says: dicey ˈdʌɪsi/ adjective informal Cold ZZRs in the wet.
  10. I'm assuming you mean the Econoseal connectors. I bought a full set from Pole Vault for the Caterham which also uses them for lighting and other loom. you do need a small non-nsulated terminal crimp tool though... tool e.g.
  11. Huh!? That rear toe is, err, adventurous... Spec is 0.2 (400) or 0.3 (410 & 430), which translate to 0° 12' or 0° 18', I guess hence their range on the sheet. But they've chosen to set the car up with pretty much zero rear toe. Could get a bit dicey. Similar story with the front. They've definitely set it up more lively than Lotus spec the GT430. I'm guessing the stability you are feeling is the increase in caster (assuming that SAI is same as KPI). At 10° increasing to 11° that's pretty huge. I wonder if I'm missing something about that measurement. It'll be interesting to see how you feel about it on twisty roads.
  12. Speaking only for myself, from the passenger footwell there is a large cable bundle that goes through a rubber gland seal up into the front access panel area, and the jump lead connections there. I then took a supply from there, with an inline blade fuse holder. Obviously, you have to run an earth wire as well as power. I didn't want to splice into the audio loom for earth, so I took both lines from the jump terminals. Switched power comes from the head unit loom though.
  13. That looks hellish good in black!! Nice

    Telemetry - Performance meters - Video Loggers

    IIRC the Hero 4 was the last one with old school centre spot metering. The 5 and 6 now have touch selection of metering area. It can be auto or fixed exposure, but it doesn't survive power cycling, so you have to remember to set it each session. More flexible, but also more annoying.
  15. cheers guys, useful info
