as i slowly save up for my 2056 rebuild, i'm still thinking about fuel delivery. i've spent some money on d-jet replacement parts and i don't really want to get rid of them if
i switch to msefi. so i was thinking, my d-jet should be able to handle a 2056 with a mild cam, but i will have to tune with the mps. i was planning on buying a wide band o2 sensor and mounting in the car. sooooo, why not just mount the mps in the car also? after reading anders d-jet site, adjustment to the mps is straight forward if you can monitor the changes you make. that's what the wideband o2 sensor is for. so why not just mount the mps somewhere within arms reach and make adjustments while i drive and keep an eye on the o2 readout? i'm just not sure how far away i can mount the mps and still have accurate fuel control. any thoughts?

that strikes me as a pretty bad idea on many levels... you're going to dial it in and leave it alone, yes? go book an hour of chassis dyno time, make your adjustments, button it up and leave it alone... |

The adjustments are hard enough to do so try not to complicate it with having it in the cockpit. Leave it in the engine compartment, adjust it on a dyno, make SURE to set the WOT properly or you will crack the diaphram.

about an hour is what it took the last time I did it. You must first have the MPS set up for it before hand. Disassemble the thing so you can remove the machined plug (WOT Stop) and then reassemble it with a piece of tape hold the plug in position.
At the dyno shop, do your run and then adjust the MPS using their A/F meter setup and then do another run to see exactly what the fuel ratios are. Should be 13.7 to 1 for part load Should be 12.5 to 1 for WOT (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif) |
