JDM GURU ONLY! ECU problem.

[jon julian]

hey i have a jdm b16 swap in a EG hatch, running a GSR ECU.....everything worked perfect....V-tech was popping at 4500RPM and redlining at 8200RPM...,..........so why the hell is it v-teching at 2800RPM and redlining at 5800RPM all the sudden?????????????????????????my speedometer is acting strange also.......any idea's???????

 

[Svr_Civic]

u get long distance ? could be it if ur goin on long trips i would try to keep it short and sweet

 

[Shiznit]

are you throwing a code? if you are youre running in limp mode, and your vtec isnt crossing over at 2800. its not crossing over at all.

 

[jon julian]

hmm, itll just pop v-tech at around 2800RPM instead of a typical 4500RPM.....its a stock GSR ECU. i have no clue whats goin on.....it was fine like a week ago

 

[Shiznit]

are you throwing a code?

 

[jon julian]

i doubt it...its just stock ECU....what do u mean by "code"?

 

[Shiznit]

is your check engine light on. does your check engine light turn on when you first turn your key to accessories

 

[jon julian]

check engine light has been on ever since i did my swap.

 

[Shiznit]

fix it. that the reason your redline is at 5800 now. you probably started throwing a new code thats causing your engine to run in limp mode. your vtec shouldnt be engaging at all. find out what code your check engine is throwing

 

[jon julian]

how do i do that?

 

[jon julian]

would that be something unplugged or a bad censer?

 

[jon julian]

anyone?

I think if you go to search and type in engine codes and im sure you will find what you are looking for buddy.

 

[jon julian]

thanks man

 

[damocivicturbo]

Sorry dude i meant to say ecu codes

 

[Steven.]

vtech huh

 

[jon julian]

if you mean i need a p30 or chipped p28......its the recommened, but i like running a stock p72....it ran perfectly fine until recently.......idk whats the deal

 

[Shiznit]

find out what code youre throwing. and why would you choose a p72 over a p30 when the p30 was made for your engine

 

[wtfh4xx]

Dude... its not V-tech... its V-TEC.

Variable Valve Timing and lift Electronic Control

 

[hondadna]

its VTEC not v-tec or anything else
