View Full Version : Can any Nistune experts chime in on my map tracing problems?

So I have a chipped ECU with a PLMS Developments daughterboard which is the non-realtime version of their Nistune.

Blah blah here's the problem. This is a map trace of 20 minutes of driving in various conditions and varied throttle positions. As you can see.. it's just tracing a linear path through the maps no matter what. I'm no expert but I feel pretty sure cells across the map should get highlighted.

Right now it's going max TP with my foot barely on the gas in neutral at 5000 rpm OR at full load, throttle mashed at 5000rpm . Seems odd to me.

Any idea wtf is wrong with this thing? It works great on boost by my gas mileage is utter shit even when I stay out of boost (12mpg)

I know they worked for Nissan Data Scan and yes I took a guess at the ecu!;)

It worked ! The value data scan had for the tp value was wrong
