Does anyone know how to bypass the ecu to let the engine go into vtec without it being warmed up? its a 91 crx with a jdm b16 w/ pr3 ecu thanks in advance

 

u dont want it to go into vtec with a cold motor. itl cold sieze and ull cry. but if you want get ur ecu chipped and have them disable vtec coolant check. then it wont look for a certai coolant temp to go into vtec. wouldnt do it if i were u IMO, just warm the motor up and have at it.

 

i understand that. i want it for that track so that i can cool down the engine inbetween runs and not have to worry about it not going into vtec when i launch it and vtec dosent kick in

 

the motor should b warm enough in the burn out box. hell just crank it up n let it idle for a few minutes b4 u run it.

 

but is there anyway to bypass it? or do u even know what im talking about?

 

yes. you have to disabel vtec coolant check on a chipped ecu. then it will go into vtec at whatever engine temp you want.

 

+1 it should be warm enough after just sitting in/driving from the staging lanes

 

i would sit in line for 35 min with my crx off and have no problems with vtec not popping. afterward i got a feilds vtec controller and that would let me hit vtec just reving it no matter what temp

 

i have never had a problem with vtec at the track with my b16 it doesnt take long for it to get warm enough. i think it would be a waste of time. but thats my opinion

 

well the problem is that i do have a problem with it i have the huge stock si rad. in it and i cools off quick and im running a direct port kit on it and i dont want to launch it with the nitrous and have it not go into vtec and hit the rev limiter. i have had it happen and dont want to happen again
