i have a 1997 hx coupe with b16a2 swap running a p2t odb2b ecu and i keep getting codes p0451 (fuel tank pressure sensor range/performance) and p0453 (fuel tank pressure sensor high input).
I know i can do the trick sending fake signal to ecu. but i was wondering if i can use a odb2 LS ecu to pass the test or am i going to get some kind of cel?help me please

 

So lets think about your question, using a 1.8 non-vtec on a 1.6 vtec, the p75 already runs kinda rich, so I've been told a couple times, with the stock map.

 

From what I've heard you could use a 96-97 P28 from a Del Sol or 96-97 P30 from a Del Sol and it shouldn't throw those codes.
