I'll be installing gauges this weekend on my 6 psi ctsc anyone here know what the usual fuel pressure should be in boost? I hope it is not over 100psi cause that's as high as my guage goes.
Thanks.
Thanks.
When I'm at my computer tomorrow I can probably find a log of fuel pressure to show you.
Edit: here is is. This is after I replaced my dying OEM fuel pump with a Deatschwerks DW200. It has (to my understanding) a 100 psi relief valve, so one wouldn't expect the pressure to go much above that. In the second log set (fuel pressure is labeled "User 2"), you can see the pressure fall off a bit after peaking, perhaps as a result of that valve.

Check out that IAT!
It was 65F outside...

AFR, Boost, Fuel Pressure, RPM, IAT, TPS, BTW
Not sure if serious or jokingIf I went with a afr gauge, I'd have no idea what is optimal and what is not
I agree about looking down although some real-time display is helpful. Logging is key, IMHO, so long as you look at the logs from time to time.
Safe AFR seems to depend on a few factors but I think the idea is that if you see 13:1 under boost, you have a serious issue. 12.5:1 is pretty much the same if you're under significant boost, where target is under 12.[/QUOT
Here is my afr from the tuning of installation. Looks like it moves around quite a bit with the rrfpr.View attachment 122887Also, I have no idea what I am looking at.
