Dynojet Widband Commander Installed.

ACRucrazy · 07-11-2004

Well, installed my Dynojet widband this weekend, Everything went great!
Have the gauge next to the stock boost gauge. The Commander is placed in the very bottom pocket of the dash.
Did a dozen or so pulls, 3rd and 4th gear, all with AFR between 11.5-11.9.
Wierd, didnt change anything on the car. FPR, injectors, all the same.
Have yet to install the map clamp.

The 02 is installed in the racepipe, between the upstream and downstream 02. I routed the wires through the shifter cable grommet, and have the loom under the heatshield and between the body of the car.
Heres some of the logs exported to a text file.

that is pretty sweet, what is suggested for your engines for the afr .. i know some cars like it leaner than others..

ACRucrazy · 07-12-2004

From what I can gather 11.5 is what everyone shoots for. So im right on.

I wanted to do a 4th gear roll from real deep to see what it would read, and yup... it was a bit lean for a second, not like im gonna be racin from 2200 in 4th gear though! LOL.

Sweet, they make a golf-cart model:

Seriously, though, how does this compare to an AEM UEGO setup? Better? Worse?

ACRucrazy · 07-12-2004

I wouldnt even put this in the same catagory as AEM.
AEM doesnt datalog, its just a gauge.
Dynojet gauge (made BY autometer) goes from 10.0:1-18.0:1.. aem goes from 11-17?
This can be had CHEAPER then the AEM...

Im diggin it, already talkin with dynojet, they are upgrading the software so you can fwd, rwd, and edit the playback for the next upgrade.
The gauge has a programable warning light, or you can add another LED light and program the warning, also can hook up an controllable out put... say if AFR is below 12.0 and RPM is above 3000 and TPS is above 80% activate this output,,, IE Nitrous, hi boost, whatever...
Datalogs not only AFR, but RPM and TP, Aem doesnt tell you RPM or TP.
