DLP A/D converter
Posted: Mon Aug 25, 2008 2:29 pm
I'm running a DLP a/d converter and an innovate LC-1 wideband.
I figure I should be able to plug a programmed 0-5v LC-1 output into the 1st channel of the DLP unit, and then select the 'DLP A/D converter" as my "1st" wideband sensor.
I figure I should then be able to modify the lookup table for AFR1 and enter the correct values.....
and then I should get a afr reading in the AFR reading field in Nistune, along with my 6 aux inputs (chan's 2-6 on the DLP unit) ?
Unfortunately it seems that when I do this, my wideband reading is not correct - but when I use the LC-1 directly, it seems to work fine?
Is it possible to use both at once? (and what happens with the lookup tables etc?) - the software seemed to crash every time I tried to get them both going at the same time.
I'm also getting weird voltages on all the other channels of the DLP unit...
is it possible it's not wired right?
my connections to the DLP unit are like so:
+5v = MAP sensor 5v pin
Earth = Map sensor Earth pin and car chassis (the LC-1 is also earthed to the same location)
chan 1 = Lc1 analog output 0-5v programmed accordingly (with AFR1 lookup configured accordingly too)
chan 4 = MAP sensor signal
Am I having an earth issue or something along those lines? or something software related?
