NX TPS switch(sensor)
The NX kit is installed
, but have a small concern. When you go WOT I have a NX TPS sensing switch that supplies power to the selonoids. It is under the dash and attached to the blue wire coming from the TPS. When you floor it there is a 1-1.5 second delay to when the nitrous comes in(verified by the light having a 1-1.5 second delay.)
We have turned the bottle off and verified that it is only a delay problem and nothing else in the system. Anyone else use this and have any issues such as this?
FYI it is at 4.3 volts at WOT and if you ease into it sometimes it is a LOT quicker(almost instantaneous)
Thanks

saftey check.... when it jumps from nothing to WOT theres a pause because it waits to see if it was a VSS error or truly WOT.
if you ease into it, it doesnt see such a large jump and just goes.
thats what ive been told about the ZEX kit anyway.... i did a little research on that back when i had a new car that didnt have a throttle cable (electronic throttlebody)

Thanks. I was not expecting such a quick answer. So no matter what I adjust it to I will not be able to get out the delay? It does show 4.3 to the TPS though. Thew safety feature is a feature of the factory computer??
Thanks

on the ZEX system i was messing with, its part of the ZEX controler.... not the cars ECM.
diffrent brand system, so that might not be the case, but i figured id share what i found about the ZEX one...
i still feel much more comfortable with a properly set mechanical WOT switch, if you can hook one up. (and you can on Fbodys)
