well, here it is! entry number two hundred in the weblog,
i’ve been writing (sporadically at times i must admit) this weblog for just over a year now, so i guess thats and entry every two days or so…
it’s been fun, though there have been times when it seemed like a chore, gaps in the blog when there were things that i wanted to write about but wasn’t sure whether to or not…
ah well, one day i’m going to go back over the last few hundred entries and update, fill in and correct (yes i may even spell chck theem too!)…
but,
until that day 😀
it’s getting ready for VWoodstock show time, hubbs has trucked off to devon to deliver emma to a craft show where she is trading some of her new jewellery designs (see them here at emmacaton.com ) and i’ve got bus stuff to do…
an oil and filter change, change some of the oil cooler hose and check the timing..
i had a positive day yesterday with a laptop plugged into the bus twiddling, trying to track down the overfuelling problem.. after checking and cleaning the plugs i think i found one of the things, i reset the throttle stops last week and that seemed to have helped, in the ECU map there is a table for ‘throttle pump effect’ that dumps more fuel through the injectors when you floor the throttle. The map has 4 setting for differeent rev ranges and each range lets you set the total movement of the peedal needed to activate the map, how much extra fuel to dump in and how long (in turns of the crank) to keep dumping the fuel in…
well, th pedal sensor range is between 0 and 200, with reasonable figure for the activation being 25-75. the 0-1500rpm map was set to kick in at 2 ! and then dump 50% more fuel in ! (basically this means that it was almost permanently on dumping 50% extra fuel in) and the slightest touch of the pedal would trigger the enrichment again!…
i reset the figures to 35 on the pedal trigger and reduced the enrichment to 35% so i’ll see how it goes… i’m bringing the steampowered PC laptop i use for the ECU mapping with me so i can twiddle over the weekend if neccessary…
got to go and interfere with the bus some more! see you all at VWoodstock show, don’t forget, i’ll be djing on the temporary radio station between 3 and 4am on saturday night. except for the regular readers we have in the southern hemisphere who might find that it’s a bit of a long drive for the weekend…
