Innovate Stuff The Innovate Motorsports people are soon to release a new toy for wideband O2 sensing, the LC-1. I just looks like a fat plug you plug a stock Bosch sensor into, and will dump out a simple analog voltage (programmable, even), so you can use everything from a DMM to your Megasquirt to some other datalogging tool, and leave the thing hooked up all the time, rather than having the big and expensive LM-1 meter sliding around in the car. Now I just have to finish assembling my MS... |

So, yes. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) You can set it up so for a given MAP and a given engine speed, you want an AFR of X. Thus, you can easily set it to run leaner in the usual "cruising" range (mid revs, low MAP) and richer in the usual "more power, scotty!" range (high MAP, all revs). Of course, this is also exactly what the VE table does, too, so this is somewhat redundant. You could set all of this up statically with no O2 sensor at all. As Dave hints, the problem with relying on the O2 sensor for real-time is that it lags a bit when you're changing things rapidly (stomping on the gas). Using the O2 code to *create* an initial map for you by setting it up and driving around carefully, however, can be a great time saver. MS has done this for quite some time, but only until the WB stuff became available has it been possible to do this reliably off 14.7:1. Nice to hear the LSU can survive an aging Type IV, too. Happy to be wrong about that one. |
