My vtec went out in my b16 eg...its a usdm b16, the wiring is similar to a 95 del sol si...code is 21 and there is no signal from the ecu to the vtec solenoid so I need a new ecu..my question is what ecu to get...which are compatible with a manual b16a motor...I am going to open it tomorrow to get the factory number but any help would be appreciated *edit* the ecu is a p30 sir ll b16a2 ecu**

what ecu are you using? Usdm or jdm?

 

usdm i believe

 

help?

 

does it say p30-900 or p30-000? does it have an "a" like p30-a00?
Have you check you oil level of you engine? Make sure it filled.

 

Check to see if maybe the vtec solenoid wire came loose before you go and purchase a new ecu..

But as far as an ecu to replace it,,A chipped p28 always works..Its kind of hard to find the obd1 del b16a3 ecus and jdm obd1 sir2 b16 ecus,,so look for a chipped p28 ..

 

Its not that hard cause I have a JDM P30 for sale!

 

its not a wiring problem I took it to a shop and they did a diagnostic on the car....so p28 and p30 will work? even if its jdm ecu on a usdm motor?

 

just curious... how exactly did you check if the solenoid is getting a signal?

which shop did the diagnostic on the car?

jdm or usdm ecu will work, obd1 or obd2 would work, but then you may need a conversion harness.

i wouldn't look at the ecu just yet.

 

chipped p28 bro...you cant go wrong..

 

ok its a p30 sir ll b16a2 ecu so will a p28 chipped ecu work aswell? or do I need a p30 exactly p30-000

any p30 as long as its an 5 spd or chipped automatic p30 (jdm). You can use a usdm p30 but hard to find and $$$(shameless plus...Hey I selling a usdm p30 lol). When you can use a chipped p28 with a p30 program.

 

 

p28 + hondata = sechs

 

Check your oil level just in case. Vtec wont activate with low oil pressure.

 

one of the first things i checked...its fine...know its the ecu so i need to be sure which will work

 

hit up phearable.net he can set you up with a chipped P28 that will work fine or a P30 will work as well
