Default AM Electronic Fuel Pressure gauge and 2nd IAT sender

1. Is there a way I can connect my Autometer #3363 Electronic Fuel Pressure gauge to the MSPNP so I can log/display fuel pressure?


2. Is it possible to install a 2nd IAT sensor BEFORE the intercooler so I can see air temps before and after the IC?

You can attach any gauge you want to you car, it's just whether or not it works off of the ecu. I don't see anything stopping you from installing a pre-intercooler iat besides just not wanting to tap it and run wires.

The way the MSPNP is set up, there's only one free spare analog input channel. So you'd have to pick one or the other, and there is no built-in circuit for this so it would take a few mods. It looks like a couple hacks to the code for EGT logging could get this working, however. Let me know if you're interested and I will get to work on what it will take.

the dual IAT circuit would be the best to start working on....as I'd be shopping for a new GM sensor from you guys....

It's been done-- there was a thread on the MS forums a while back on how to do it. It was a .ini hack and I don't recall if there was a code hack needed, I don't think there would be to just bring in the IAT signal, but there likely would be to add a gauge based on these readings. At a minimum you could get both readings and do the math yourself... no gauge but plenty functional.

Only if the mod causes the damage... We're pretty good about taking care of people though man. Even if the mod causes the damage we'd work with you to correct it as affordably as possible.

I'll get to work on that today. It's going to take a while - as of now, this is all the documentation on fuel pressure logging that I have to work with, and maybe some forum posts somewhere. I'm pretty sure I can get a good write-up, but as you can see I'm going to have to do a lot of work on it.
