I'm going to try to tackle tuning myself and was wondering how many of you guys have experience with the different wideband readers available. Considering my budget, my choice will be limited to one of the four "affordable" choices: zeitronix zt-2, innovate lm-1, plx m-500, and aem gauge type uego, in that order. All except the aem are capable of datalogging 5+ inputs. I like the zeitronics best because the display shows lambda, afr, boost, and egt all at the same time. egt probe can be bought for $65 as opposed to a $175 gauge (and has a peak/hold function for all readings), and boost solenoid is $139 while a comparable [peak/hold] gauge is ~$200. the diplay isn't too big, kinda stealth'ish. unlike jack-me-blinging gauges. the innovate for a similar price offers the same sensors contained in the datalogging unit, plus an g-sensor/accelerometer (sp?) but it diplays information in a big box that is to be read while tuning not driving...can't be dash mounted. The big advantage of the plx is that it is wireless (wireless datalogging ). aem just looks nice because the whole unit is self contained in a gauge that easily fits in a 2 1/16 pod, but offers much less.
heres a pic and the websites of each of the units
http://www.zeitronix.com/Products/Products.htm $279 w/ out diplay, $399 with display ($25 off coupon available online)
http://www.innovatemotorsports.com/products.php$349 without LM-3 sensor box, $589 with, or $429 with LM-2 rpm converter
http://www.plxdevices.com/prod...s.htm$499, no extra sensors
http://www.aempower.com/product_ems.aspabout $400, no datalogging
finally, here is a copy of a test performed by import tuner comparing different widebands. don't pay too much attention to the first comparison, it was done closer to the turbo. the second was further down on the dp.
