Hmm I can’t seem to make the search tool find anything AFT related…
Anyway can anyone tell me if there is a WOT switch on a 2010 Exige S that I can connect a Stack AFR gauge to?
cheers

Anyone know anyone that might know?
I’m a bit confused by your question, but I think I might know…
Do you mean AFR?
There is no WOT switch it is all run by the ECU from the throttle position sensor, you can get the throttle opening % from the OBDII port
whoops many apologies i did mean AFR ! and thanks for your reply.
Do you think it would be easier to add a WOT micro switch, rather than adding all sorts of extra gizmos to read the OBDII port? or would this be a little in accurate. here is a snip from the afr manual:
“Wide Open Throttle Peak/Recall Mode:
WOT Peak/Recall mode provides you with a quick and easy way to find out exactly how �Lean� your engine / vehicle got during the last pull,
run, or race. This value is recorded when the Brown Wire in the instrument harness is connected to a good engine ground via a normally
open, momentary closed wide open throttle switch (not included, see wiring diagram). This allows peak readings to be sampled only during
wide open throttle conditions. If the Air / Fuel Monitor gauge will not be used with a Wide Open Throttle switch, connect the brown wire permanently
to a good engine ground to continuously monitor for peak conditions.”
cheers G.
The peak lean recording will be totally useless on our cars as there is a momentary very lean spike when the cam change occurs…
Fit it without , you’ll find the gauge easy enough to read while on a pull …
Hmm okay - I guess it depends on how long you keep your foot in there - gauge is already installed along with Oil T&P in a nice little stack infront the gearstick. - Very amusing until up to temperature, it’s like an 80’s disco with all the colours the gauges display until everything is settled!
SO you recon the Gauge (if set with WOT) will display an incorrect lean value due to the cam change - sounds logical I think it has a certain amount of buffering…
