ZT2 wbo2 tps readings

[suprra_girl]

So is it common for this to be inaccurate? If not......

Mine is reading 45% when i'm at about 3/4 throttle, i assume that this would also mess with my wot maps even though my fueling appears fine and changes to open at expected time.

I was thinking of adjusting the tps via the zt2 but....... the car actually runs fine, no problems, surging, codes etc

What do you guys think?

NO DO NOT ADJUST THE TPS BASED ON ZT2!

The reason its showing that is because it won't automatically adjust to your specific TPS voltage output like an SAFCII would. Personally i think they need to change this in the software but its not a big deal.

The TPS output helps more as a reference then anything, just make sure you have an idea of what the ZT2 output means in relation to your actual throttle input

Ya, mine was out too. Pretty sure the ZT units are set to use a 0-5v scale, and my TPS only goes to about 3.5v max.

It shouldn't affect your maps, though, because the ZT unit just reports AFR, no RPM / EGT / TPS readings to whatever you are using to control actual fuel delivery, in my case, a MAFT Pro.
