sct question

[oneturboforme]

To you guys with scts when you start your truck does it show any frp or is it only when the trucks running? Think i dusted my fuel pump...

 

[Mike@MPD]

When you are cranking it should be going up

Yeah you should be able to read it while cranking do u have air in the system? I know u have a custom fuel system. Can you check fuel supply

Apply to to hpfp is 15psi... Before there was a 0osi offset from the hpfp inlet and the return line... Now there is a 3psi difference... Here's whats happenened..loaded erics tune. Started my truck. Let it warm up for 10min went and drove it maybe 100yards fuel pressure looked good. Turned a corner and gave ut about 40% and it just shut off... maybe the hpfp has a block in it? It could be the sct itself tho.. my truck seems to hate them

I don't think it's a tuning issue. Sounds like something else, like air or a bad pump. Are there any codes?

 

[oneturboforme]

No fuel codes I have a cruise ctrl circuit stuck code and a turbo actuator error code..

 

[oneturboforme]

Codes p0578 and p179a

 

[Jeff@Spartan]

I thought you could select EGR delete and single turbo on the SCT so that those codes don't come up?

 

[oneturboforme]

There wasn't an option when I loaded the tune to my truck

It should have asked you dpf delete, egr delete, tire size air intake and maybe a few more.

 

[oneturboforme]

Ya it asked me those but not a single turbo... I think i found the problem.. pulled the return side of the hpfp with the air dog running it just trickles out...

 

[tbsimmons]

The single Turbo and stuff is under User Options I believe.
But all of them are set to normal as default, at least they were with mine.

Yes, TB is correct, you have to select "adjust user options" when loading a tune, It is after Air Intake (Y,N), EGR delete (Y,N), etc.
