i have a ls-v a1 bottom, built b16 head....
well anyways i was driving then i down it 2 second at like 60 and then at like 7 grand it starts to tap out and im using a gsr ecu and it taps at 8 half!! so im wondering why is it tapping at 7 when it supposed to tap at 8 half!??? i was wondering if its the vtec oil pressure switch?!?

 

your car probably just hates you for dropping it into 2nd gear at 60 mph expecting madd powazzz

 

hahaha i think so boss.... but do you know whats wrong?!?

 

If any code appears, rev will be limited. If it's bad it will go into limp mode. (just enough to get it home)

 

either ^ or your tach is off all of a sudden.

 

Is ur car throwing a cel???

 

Patient . it hurts when I do this ...

Doctor: so don't do that.

 

i didnt check codes... when i bought the car awhile back when the sohc was was still in the car... the guy said that he cut some kind of wire that prevents the engine light to come on?? but idk what wire that is??!? anybody got an idea where this wire is at????

 

wow, you have a real problem. ideally you would have walked away once that info was given.

 

dude for one use a p28 chiped i think that will helo about due to the p72 is gona look for the butterfly sensor. either then that good luck

 

telling honda's not to rev high is like telling a woman not to have an orgasm

lol

 

its all in the way you "ask them not to rev high". they can/will rev from ~800-8k all day, but dont expect flawless performance when you downshift at ~4500 and bounce off 7k+

 

he probably cut MIL output wire from ECU to MIL lamp. check according to vehicle/ecu

 

if the gsr ecu it 8.5k why is my car tapping at 8100???! could it be the vtec pressure switch?

that code did come on...

 

More than likely. Vtec pressure switch monitor oil pressure, if not enough pressure when your are at the vtec crossover point, then the vtec system will not function, if pressure is too high before vtec crossover point then it will throw a code and again your vtec system will not function. Either way revv will be limited in some way.

 

hey thanks man...so most likely its the vtec oil pressure switch?? just the other day it wouldnt even pass 7k!!!
