Hey guys i have a 95 civic hatch i swapped a b16 a while ago and just recenty decided i wanted to rev it to 8k and i found it won't rev past 6900... thought it was the ecu, but swapped out multiple ecu's and chips that i am positive they are good and still 6900. searched last night thought maybe it was the dizzy so i tried my friends tonight and still the same thing. i'm out of ideas and can't find anything. the car was never revved that far before cuz is had a sohc in it so anyone with any ideas please help me out thanks.

 

What programn u running

 

chipped p28... tried the ecu in my buddies car and revved to 8k like its chipped for, threw it back into mine and 6900... phearable chip.

 

Could be chipped but when it gets tunned they can disable things as well addIng features like 2 step and etc ur buddies ecu might have complete diff set up... Not100%

 

my friend has a bone stock b16 just like mine i tried his chipped ecu, my chipped ecu and a p30 in his car they all rev around 8k but when i put those same ecus in my car they hit rev limit at 6900

 

has anyone else had this problem?

 

ANYONE???

 

naw man u think ur tach is miss reading

 

i thought so too so i wired an auto meter tach in and its reading the same as my tach in the cluster, i checked every sensor and they all have the correct voltage going to them

 

Your car is trying to save you from going too fast

Check -Fuel/Spark/Air

Filter/dizzy/fuel pump/injectors

Somewhere something is holding you back

 

tried new dizzy, fuel filter is 2 weeks old and i have the proper fuel pressure just checked today

 

are you getting any CELs?

 

nope there is no cels thats why im so confused

 

is vtec engaging? it almost sounds like fuel cut from the injectors like it will do to a boosted car with a bad fuel pump.... but your not boosted.

 

vtec is engaging, the car is n/a but whats weird is it has the correct fuel presure

 

huh.... only other thing i can thing of is the VSS is acting up and making your tach and ecu read different things causing a rev limit.

 

it has the correct voltage running to it ill swap mine with my buddys and give it a shot thanks man ill let u know if it works

 

are you sure the fuel pressure was there when you were reving to 6900. It may be your pump not supplying enough when you get it up that high and its cutting out

 

it was the tps sensor i put a new one on and everything is all good thanks for the ideas guys
