i just did a auto to manual.
and a obd1 gsr swap.
in a eg..
vtec is not working. its on a stock p72 ecu. and everything is pluged in.. dose it have a to grounded? do i have to wire vtec in?

 

Did you run wires from the solenoid to the ecu?

 

u have any codes ?
did u wire up corecly

 

check the engine oil level, vtec solenoid, or the crank sensor

 

thats y yur vtec isnt working its wired up, wire it up, what car

 

how do i wire it up?

run a p28 :D thats what im runing on my eg works fine

 

Dude, he has a stock GSR with probably a stock intake manifold. The p28 is for a SOHC vtec motor and doesn't have the circuitry to deal with his intake air bypass valve, nor does it have the circuitry to deal with a knock sensor. He already has a stock p72 ecu, he just needs to run a wire to the solenoid. How is buying a whole new ECU and then getting it chipped with GSR basemap going to help him if VTEC isn't wired up?

 

hey i have a 99 si ( legit em1) i put a gsr bottem end and 99 si head with ctr pistons in it. the car runs great but vtec doesnt work. theres no cel and theres plenty of oil. ive had the head apart and everything is in working condition, when i put a obdi jumper and ecu i get a code9

 

A few months prior I did the same exact thing to my car except with a p28 ecu. Plug up your vtec sel. If I am not mistaken there is one blue wire (which goes to the ecu) and one black wire (which is ground). Find the according pin on the ECU (what I ended up doing was cutting one that was being used for the gear selection indicator, put it into the plug on the ecu where the vtec pin was located, and ran it straight to the sel). It worked perfectly the first time for me.

 

exactly so stfu ej8 and american i did the samethig and have had never had a problem with the p28. the only thing diffrent on a gsr head is the butterflie witch have nothing to do with the air bypass valve
