Alright guys, here my problem Ill spell it all out for you.
I have a 94 Ls and we just dropped a b16a sir -ii engine (jdm) into it.GSR tranny. Everything runs fine, no throwing codes of any kind. BUT theres no VTEC. I tried the usual symptom checks such as connecting power to the vtec signal wire and the vtec clicks so i know it at least works. I checked the screen and its clean and not clogged..Double and triple checked the wiring its good. i cant figure it out and its driving me nuts. the only thing wrong with the whole car is that my cluster is messed up. It says im 10mph over what im driving. But i do not beleive that to be the VSS because it still reads a mph and isnt jsut at zero. Any suggestions on what to check would be totally awesome

I can fax you the OE Vtec trouble shooting guide if you want. I have access to Alldata and Mitchell On-Demand.

PM me and I will try to get it too you tomorrow. I have a fax at my apartment and the campus is less than 1/2 mile from where I live. It will be absolutely no problem to get you any flow chart for troubleshooting that you need.

which ecu are you running? are you sure the wires are on the correct pinout? Also, vtec does have a speed check (i think its 18 mph), so it won't engage until that point. if your speedo won't break 10 mph, that could be your prob.

coolant not warm enough? or not even getting a signal could cause it to not switch into vtec.
