<\/a><\/div>\nIt is still an absolute mystery why the one I bought didn’t work, but my instincts indicate that it has something to do with the mix-n-match nature of the engine and transaxle combination.<\/p>\n
In any case, it’s streetable, though the shifter is a pain to deal with. I plan to install one of these, or one like it<\/p>\n
<\/a><\/div>\nI have dedicated a number of hours tuning on the EFI system. At first, I was fighting a bad O2 sensor and now I’m fighting what I can only conclude is erroneous injector specifications. All indications are that they are 245 cc\/min injectors. Using that number, every iteration through the basic fuel equation returns a ReqFuel number of 22 or so, which it then divides amongst two injectors. Trouble is, the engine will hardly even idle if the number is below 30 and it doesn’t run with a decent AFR until about 44. The astute observer will note that the number that works is exactly double the number given. This leads me to wonder if I should keep thinking that I should be able to trick it into by telling it my injectors are half the flow they are, hoping for it to come back with a 44. It apparently doesn’t work that way, for telling it 125 cc\/min comes back with, like 28.<\/p>\n
So, ignoring the set up and using 44 as the ReqFuel number gets the thing running.<\/p>\n
I’ve been using TunerStudio instead of MegaTune. I like it better overall. The dashboard configuration is very easy to customize.<\/p>\n
<\/a><\/div>\nWith MegaTune, I would have to swap out one gauge or another when I was working on various pieces of the tune, but with TunerStudio’s dashboard, I have all the gauges showing at once. I need to play with their layout a bit, but they are all there!<\/p>\n
TunerStudio’s VE Analyze Live!<\/i> feature is a pretty cool autotune facility, however in my case, it seems to want to lean out mixtures that are already lean, where I would expect it to richen them. Perhaps I have some settings wrong. In any case, it’s still cool to watch it change the numbers and to see the engine respond to the changes.<\/p>\n
With continued vigilance, I hope to have this thing reliably on the street in the next few weeks.<\/p>\n","protected":false},"excerpt":{"rendered":"
The clutch issue was resolved by continuing to swap out pressure plates until I found one that worked. The one that finally worked is one that was on the free parts shelf at the BTW clubhouse. It was coated with a fine layer of rust, but it cleaned up perfectly and more importantly, it works. … Continue reading Another Long Overdue Update on the Dragon Trike<\/span>
