I have a 93 Del Sol with a b18c1 swap. I was driving on the highway my v-tech doesn't kick in anymore, speedometer went dead along with the cruise, plus it starts to die if I don't push on the throttle. My check engine light isn't on. Please help!!

 

it's vtec, not v-tech, and it doesn't sound like the ecu to me

 

Do i have to post this again



Doesnt sound like ECU to me either.

 

hmm swap it with someone elses?

 

What ECU are you using??


If you just did a swap,...

First of all....
here is the check list after a swap....if you want to hear vtec changeover
1. make sure all sensor are connected, and are in working condition (check ECU for codes)
2. run PREMIUM fuel (drain the crapy gas out if you did not!!)
3. egine must reach normal driving /operating temperature for vtec to activate.
4. Make sure oilpan has no dent on it.
5. check for ignition timming and bad axle, both can cause motor to produce less HP to the ground...therefore equal = no vtec power
6. stock del sol intake/exhaust can do alot of restriction to your newly swap b18c, it sometime cause vtec to not activate.
....this is just a few, I know there is more to this list you guys feel free to add on to it....

 

Check your ground connections for looseness and tighten them up and don't forget the one on the thermostat housing.

 

i had a similiar problem. there is a fuse for the VSS. if that goes out your spedo wont work and neither will your vtec. plus its tied inot your altenator so your batery will be drained and all your interior **** wont work. check that fuse. and all conections. bet its something really simple

 

yep sounds like VSS car needs to be going over certain speed for vtec to kick in.

 

v-tec thanks guy

 

yeah, same thing happend to my friends B16, his VSS cable was broken, so you might wanna check it

 

I got the full swap its for a b18 so the ecu is for it but it makes a humming noise when i floor it Ive never heard that before
