Adjustable map

Who offers an adjustable map sensor these days?

What are you trying to accomplish?

 

[clean4drxj]

I'm trying to add more fuel for the air coming in and going out.

You'll have to build your own but it's easy enough to do with a few $ worth of Radio Shack parts, some automotive wire, and a soldering iron:

Radio Shack? There ain't been no Radio Shacks around for centuries. You been freeze dried or doin hard time?

Radio shack still exists in my small city. They are also on the web. Maybe a frys electronics store near you?

 

[bigdaddyjlove]

We do have Frys. And there is always the internets

Does moving the air temp sensor help any?, I have a good spare that I was going to in a cooler spot.

Doing hard time boiling myself away in one of the hottest places on Earth.
Here are the parts you need:

Total cost a mere $22.

What year?

Moving the IAT sensor helps.

 

[clean4drxj]

Late 95(obd2).. Good I guess I will try that and see what happens.

What makes think you need to add more fuel?

 

[clean4drxj]

I have all the the mods for more air in and out on the engine and it tends to run on the warmer side tho never over heated. The only real way to tell is to pull the plugs n check them out

 

[Talyn]

None of those will tell you anything about the air fuel ratio. Reading plugs is difficult on a fuel injected engine and then it only works for the last spot you had the engine running after shut down.

AFR gauge is the most accurate and trouble free way to determine what it is doing.

 

[clean4drxj]

A/F ratio gauge is on the list but I have so many other things to finish, like plumbing my brakes on 35 spline 9" and hp44 combo, make sure they worth with the stock mastercylinder ect.

 

[kastein]

The computer is adjusting the amount of fuel it is putting in to what it should be anyways. This is like turning the steering wheel a quarter turn right on the steering column so you can turn right better. The steering stops (injector flow rate and fuel pressure) are still where they were and the steering box return to center (O2 sensor in closed loop) will still bring you back to the same place. And you are doing it blind because you want to do this before an AFR gauge.

Again, what are you trying to accomplish here?

 

[Talyn]

With just simple air flow mods (CAI, TB, header, exhaust, etc) the PCM will have no problem maintaining the desired afr.

Even with a mild cam the ECU will adjust the fuel trims enough to run properly.

I've seen several mild strokers that would disagree with this statement.
