does TPMS light cause engine cut off at speed
i was at a track this weekend with my friend and his Evo X. he has after market wheels with R-comp and no TPMS sensors. the TPMS light was on. the engine was cutting off towards the end of the back straight. there's a long left hand sweeper leading into the back straight. at first we thought it was fuel starvation but it happened even at 3/4 tank of fuel. then we thought maybe the car was running too rich and it was miss fire but that didn't seem right also. the cut off happened at different rpm from 4000 to 6000 but it always happened towards the end of the back straight at around 100 mph. then i thought maybe because ECU thinks there's a flat tire because of the TPMS light being on, and it wouldn't let the car go past 100 mph.
does anyone else have similar issue?

Its something else unrelated to the TPMS. My car was out at the track at Autoclub speedway with aftermarket wheels and no TPMS. Car ran great with no hiccups whatsoever. In fact, my TPMS light went out after the track session...but came back on shortly afterwards.

Its just the ECU. It has nothing to do with TPMS. Evo X's have that problem of the limp mode from time to time when the car is pushed hard with the factory tune.
A flash will fix that.

The first couple of laps would be fine at 100-115 but after the TPMS warning came on it was like the ECU set a speed limit and wouldn't let me over 95-100 mph (6500rpm in 4th and 4400rpm in fifth). On the way homw when I had the stock wheels back on the car I did a few high speed pulls with no issues.
