can you actually tune with only a wide band display in numbers without datalogging and looking at the A/R chat?
i mean like e.g first tune up to 1k rpm then increase 500 rpm on every run.?
just saw some WB kit on the net goes for like 300 with sensor but has no datalogging function...

 

Sure it's possible. It's not easy because you've got about 3 sometimes 4 things to watch at the same time. Thats why dataloging is so handy, but it can be done without. Also, depending on what your using to tune with (Uberdata, turboedit etc.), Disablingclosed loop will help out with the partial throttle tuning.

 

i`d be using Uberdata...

 

get a friend to sit in the pass seat.

 

hey, are you the guy who activated his vtec by having a buddy put two wires together? man that was ghetto fab.

 

get somebody to record your guages and your tach with a video camera

 

Works very well actually. Especially if you have DV camera that can go frame by frame clearly

 

Who needs dattaloging? J/k, I'd use it if I had a laptop

 

BTW where are the difference on datloggin between the tech-edge kit and the one where you weld a little pvc board directly on the ECU?

..and yes. Sensor datalogging (as with TechEdge) is said to be "more accurate", however, accuracy is in the eye of the dicatator. I.E. what the ECU "sees" is more important than what the TechEdge dataloggers sees.

So, personally, I say that I would rather have the ECU spit out what it thinks it's seeing, vs what any outside source would say that _it_ sees.
