As you can see in the Motec thread on the M170 (latest ECU fitted to a superbike) wheel speeds are totally wrong compared to even a ghetto GPS velocity trace (as per the Motec garmin ghetto facility logged on the ECU at the same time).

But at absolute MINIMUM I would like to see some kind of velocity trace, YES. If its based off wheel speeds then you are always going off a wrong trace then overlaid on top of that is the honesty of the calibration to make the speed reading right + the wheel slip factor added on top.

To measure velocity CORRECTLY to determine honest speed you really need a GPS signal, top shelf stuff is around 100Hz Ghetto like Motec is around 5Hz lol, either way its 1 million times better than a wheel speed trace

Consider your self edumecated LOL

p.s. To validate ANY claims of speed to distance I also want to see the hieght and slope of where you run, again any decent GPS instrument will allow this, most ECU hack boxes will not , run down hill = much much faster , most people cheat themselves LOL

In all seriousness, PSI welcome, let us know who you are and what your set up is.

It sounds like its NZ or Australian to me, as no one I know would run a Microwreck product lol especially combined with a Link ECU haha.

If its a drag car link us some specs, times weight etc

p.s. I tuned a car with Microwreck ignitor with ICE boosters in 2004 with Water Injection and low AFR, it just always fouled plugs (racing ones). Given the Links ability to blow up engines when running CDI's if you use any of the limiting functions then this combo is probably not a bad thing anyway
