I bought a Vtec head off of ebay but it doesnt say Vtec on it but it has the soleniod and stuff on the side. Could someone have sold me a Vtec-E and sold it to me as a Vtec, like do the Vtec-E's have the word Vtec on the head??? Also I got a P28 ECU and I'm thinking that maybe its and for an auto and not a manual. Is there anyway to check this out? I need some answers ASAP so any help would be much apprecaited, I can't keep getting rides to work. Thanks In Advance for any help.

 

the ECU sticky in this forum will help you tell the diffrence between a manual or auto, if not... http://www.pgmfi.org

the valve cover doesnt necessarily say "vtec" on it....pull the cover off and take a pic of the rocker assembly

edit: look for the code stamped on the head, P08, P07 etc etc

 

rule of thumb with ecu's is that if the last 2 digits are 49 or lower, it is a manual ecu. 50 or higher is an automatic. yours should read something like 37820-P28-A**, where the ** is under 50.

as for the head, what motor did it supposedly come off of? z6 or y8?

 

Y8 heads=HONDA written on it.
Z6 Heads=Some valve covers only have honda logo on them, some have vtec written straight across. If the code of the head has P08, its a z6 head.
DX/CX Head=No VTEC solenoid, saids 16 valve/8-valve on the valvecover.
VX Head=Not sure about VX heads with VTEC-E, never seen them before, but if its not the ones above, its a VX head.

 

if it has the vtec solenoid your worrying for no reason

not all sohc vtec valve covers say vtec on em

 

It will run fine with an automatic ECU, it will just give you a CEL. You can open it and make two small changes inside and that will convert it to manual.
