Safety - Protection tab

I want to add lots of Safety and protection.

My car is turbo charged with a water to air cooler which is pump driven which is a failure point.

My engine was a 3.0 V6 with a 3.4 stroker kit, slightly lower compression.

I currently have, which was set up by the tuner i assume unless they are standard.

Coolant Temp

Oil Temp

Oil Pressure

Lean Protect.

 

Based on the pump driven water to air cooler would it be a good idea to add Intake temp to the protection tab?

I also have a aftermarket Fuel pressure sensor - would it be a good idea to add this also?

 

How do i add additional protection tables?

 

I'm not convinced Coolant temp is setup properly as it only has a lower limit for if it's too cold, not for if it's too hot. Is this correct?

Also i don't think oil temp is set up or active at all because the entire rpm range within the table is higher than my car can even rev to.

Oil pressure, what would be considered as a safety point? currently set to 7psi 1000, 17psi 2000, 30psi 3000, 40 psi, 4000 - Does this sound about right? is 17 psi ok or a little low?

 

I would never fiddle with the tune as i'm not tuner, but seeing as i spent all this money to upgrade to the Infinity mainly for safety and protection i want to make sure i am getting the most from it.

 

I also noticed in the Wizard there is no fuel cut set only spark cut for safety, i'm guessing this is right?

 

Thanks Guys.

Here is my current safety  

Here is my current safety tab.

Does it all look good as per my first message? Lean safety i guess work off uego? Surely it should have 12.5 as a safety? the table in the image is using different units by the look of it.

I think you will be best

I think you will be best suited working with whomever setup the Infinity to discuss your questions. There is no right or wrong (well, maybe some wrongs) limits on anything aside from what is required fo a specific application. From the questions you are asking, you probably should not be changing values just yet until you become more familiar with the workings of engines in general and how your specific application needs to be set up.

This isn't meant to be critical of you for trying, just looking out for your engine. There are some basics regarding general fuel injection covered in the AEM manuals, and a great deal of info available through online resources such as EFI University and others. I would recommend getting more familiar with general FI terminology and usage/setup before diving into making changes.

Thanks, I know I shouldn't be

Thanks, I know I shouldn't be meddling with anything in terms of the actual tune but i have this expenisve Series 7 ecu with all this safety on a brand new engine because my last motor failed due to low oil pressure.

I can't really do any damage in the protection section, i work in i.t. so have a logical way of thinking.

I can see from the above clearly that the oil temp protect isn't active because the trigger is above my rpm range, surely it should be 1000-2000rpm like oil pressure.

I can see coolant is setup in terms of being too cold but there is not too hot protection.

The lean protect i don't get as it's not based on AFR or if it is then it looks setup wrong.

I have a AEM fuel pressure sensor that i would like to add and Air intake temp because i believe this would help detection of a failed water to air cooler pump.

The lean rotect is based on

The lean protect is based on lambda, not afr. Lambda is basically the percentage of the stoichiometric ratio of the fuel. A value of 1 is stoichiometric. Higher than 1 is leaner, lower than is richer.
