After Boost/Vac and EGT (or A/F), what guage would be best to add for a car running 6-7 lbs. and around 220whp?

 

oil pressure or fuel pressure

 

Id say Fuel Pressure.

 

oil - no/low oil pressure is a killer.

 

if he's running a FMU, loss of fuel pressure is a killer also. I'd go for them both, but if I had to choose, oil pressure.

 

go with the fuel pressure. The oil pressure is good to have but if you can only get one get the fuel

 

well I'd take egt AND a/f, but between oil and fuel I think oil. The way I see it is if your fmu dies, you're fucked anyway. If you got an oil leak, you can detect and have time to prevent damage. Makes sense in my head.

Edit: If you det, take it as a hint/opportunity to set up a proper standalone

DIY Wideband O2

 

well when you are low on oil your vtec will not kick in so your car will run like ****. so you will know before hand. i say fuel pressure especally if you have an fmu. also i say an a/f ratio gauge over the egt because the egt can only change so fast. you know what is going on as soon as you see your a/f go into the red.

 

Integra LS = NO VTEC

Get the oil and fuel. I had OIL, A/F and Boost.

The way I look at it, why not spend a couple bucks now instead of spending over 4 grand when your motor blows. I think I spent around 4 - 5 to get everything redone.

 

I 2nd that!
