madspikes 41 1 Cars Posted March 13, 2008 The supercharged pug is ready for mapping! Does anyone have any tips for mapping using a MS on the road. The car is fitting with a wideband lambda. Is it just a matter of driving up and down at steady rpms and loads and tweeking the mixture. Or is best just to drive around, stop look at the data logs, do some tweaking, then drive some more? Suggestions please. Anyone know of a private road, I could use...? Mad. Share this post Link to post Share on other sites
Sandy 191 Posted March 13, 2008 Find somewhere really quiet, straight, good visibility etc! Try and focus on the low load normal driving areas first, then work outwards from that zone with care, starting slightly rich and leaning as required. Share this post Link to post Share on other sites

brianthemagical 1 Posted March 13, 2008 make sure you get the idle done ok first, may give some indication of errors, like req fuel. megatune has a built in data log tuner somewhere as well, so go for a run, then set it to do it's thing, and keep doing that for a bit, thn final tweaks after that. theres no substitute for an RR to fianlise.

cybernck 402 1 Cars Posted March 14, 2008 well the best bit of advice is - DON'T DO IT YOURSELF! get someone else to drive while you monitor and adjust things on the laptop. Share this post Link to post Share on other sites
base-1 17 Posted March 14, 2008 Do what has been said, and get a knock sensor, or at least make one with some washer tube and ear defenders Share this post Link to post Share on other sites
madspikes 41 1 Cars Posted March 14, 2008 The plan was to have someone ride shot gun and operate the laptop whilst I drive! I have a knock sensor but have no idea where I can mount it on the 8v. I have driven the car on part throttle, just taking it easy and it seems ok, so I think the basics are working ok. A rolling road session would be needed to finally set the fuelling and the ignition timing, any good RR who do MS stuff down in dorset? Mad. Share this post Link to post Share on other sites
niklas 1 Posted March 15, 2008 I have a knock sensor but have no idea where I can mount it on the 8v. In the same place as on the 16v? You may need to change the bolt to the 16v one but then it should be straightforward!? Share this post Link to post Share on other sites
madspikes 41 1 Cars Posted March 16, 2008 It all went very well. Adjusted the fueling on incressing load until we heard knock / pinking. Then with a rough fuel map adjusted the timing... Then back to the fuel... Car now drives great... More mapping needed though. I thought the knock sensor bolted down near the centre oil filler hole. The 8v doesent have a bolt hole here...

pug_ham 244 3 Cars Posted March 17, 2008 I thought the knock sensor bolted down near the centre oil filler hole. The 8v doesent have a bolt hole here... Don't they fit to the centre main bearing cap side bolt by using a longer bolt than normal? Graham. Share this post Link to post Share on other sites
madspikes 41 1 Cars Posted March 17, 2008 I like the sound of that... If so I could just get the longer bolt from pug and bolt it on! Jobs a good'em! Need to look into that. Share this post Link to post Share on other sites
