I just bought the Innovative LM-1 with Auxbox and the Auxbox has it's own built in MAP sensor for registering boost. It will also use a normal pressure type line ie. the stock boost gauge line but Innovative says that it registers boost more correctly via it's built in MAP sensor. What's the best vacuum/boost source for the MAP sensor? Innovative suggests something after the throttle body.

 

Buy the Buschur MAP sensor adaptor. It goes in place of the stock one on the intake mani. But that will only work with the AEM EMS. I dont think you can just replace the stock one with another. I am not sure what the stock ECU would do. I may be wrong on that though. I run the AEM EMS and BR's machined adaptor worked beautifully.

Other option is to drill and tap.

 

I dont know what the LM-1 sensor looks like but im am sure it just has a nipple off of it for a vaccum line/hose to go over it. Just put a plastic/Metal t-fitting off the intake manifold "anywhere but for the brake booster hose" and run it to the LM-1 sensor. Off the intake manifold will give you more accurate readings to what is the actual psi the engine is getting.

Hope this helps.

Also make sure you use zip-ties and or some sort of clamp.
