TEC II questions


rags

Recommended Posts

Just picked up a TEC II for my turbo 240 and hava a few questions for the experts. The first is where to mount the sucker in a 71 when the battery is in the stock location? Who has any maps that work with a stock L28t without an IAC? Will the Nissan knock sensor, water temp sensor, throttle position sensor, and O2 sensor work? Any help is appreciated. Joe

I've seen them mounted either on the firewall, or on the front left of the engine bay, on the wheelwell (engine bay side, of course) in front of the strut tower.

 

I would not recommend trying to use somebody else's maps, as they are pretty sensitive as to cam profiles, injector sizes, etc. You'll probably spend more time trying to 'straighten out' somebody else's map than you would in starting from scratch.

 

As far as sensors,

The water temp sensor should work.

 

Not sure about the TPS - is it a variable resistance type, or just WOT and closed throttle switches?

 

Not sure about the knock sensor - do you know it's characteristics?

 

The O2 sensor will work, however if it's not a 3- or 4-wire type, I'd replace it with one.

 

Sorry I can't tell you more, but I didn't start with the L28t electronics, so when I installed my TEC, I went with the recommended GM sensors.

 

If you have specific tuning questions, I'd be more than happy to help...
