1. Did you ever figure out a way to log 2 egt's at once then?

2. You used a pwm output correct? So this won't allow you to fine tune like FJO's 3d map will it? I am considering ditching my PFC for my 13b-re build up and going with the haltech. Being able to control the injector from the haltech sounds great but I want to be able to fine tune different points on the map like a fuel injector (like FJO) and just need to know if that is how it works.

1. havent really put any thought into it yet. I think i should be able to log a generic voltage input. i dont remeber exactly how many inputs i have left. To be honest, its to cold in the garage to do much.

2. i use a pwm out. This allows you to fine tune exactly like FJOs setup. Imagine having an additional load v. rpm map aka a fuel map for your alchy. It works well enough for me so far. I have barely gotten to drive the car after the tune. Hopefully i will get things together soon and the weather gets nice.

Do you use any other outputs to control the injector? I'll be using 2 meth/H2O injectors so I need to know what kind of outputs I need.

What kind of output did you use to control the fuel pump?

I would not be surprised if you can run 2 of the water injection solenoid drivers off of one generic pwm out. Also, it appears that you can set aux 1 and aux 2 to be the generic pwm out so you probably could run 2 solenoid drivers that way as well. I would check with haltech to make sure.

i used a relay to turn the pump on. it is always on in the current configuration. i will probably add a boost activated switch that kicsk on at 1 or 2 psi or something like that.
