Default Check out this Air/Fuel hack!!!

http://www.autospeed.com/cms/A_8/article.html


What they're describing towards the bottom of the page is a circuit that SHOULD make it possible to run 450's plus boost pretty well. You guys should check this out!

Nice link!
Auto speed always seems to have good articles.

I wouldn't use a voltage divider for a dynamic voltage/current application. The signal the ECU gets would be off.

voltage dividers give equal current and current dividers visa versa!!!!!!!!

I don't know that much about electronics... Are you saying this wouldn't work well for forced induction applications?

I think on Autospeed, they describe this as a solution to using *slightly* larger injectors.

Coltage diveiders do not give equal current. They simply divide the voltage. The current draawn is dependant on the laod that is in parralle with the last resistor Rn.

That bears a slight resemblence to English..

Voltage dividers suck. If the load changes, so does the voltage division. Works great in a voltage divider bias circuit as it plays off a transistor, but in and of itself it's a joke of an idea.

Used to tweak the output of the MAP sensor, it would do OK as filetofit/Chris has proven on HT... the ECU itself is fixed load, so you can dial in th correct division. If you think it's an idea you can apply widely you need to pick up a book on basic electronics and learn basic ohms/kirchoff's law.
