Modifyed Fuel Pressure Regulator

Just take the guts out of it end cap spring barrel and put your lift pump on a switch

Might idle funny though.

Hmmm.. Mark is always pretty easy to get ahold of for me.. Emailed him about a tube update Friday and got one back a couple hours later after they closed!

Lucky. I emailed on a Friday morning to just the generic email (don't have Mark's) and didn't hear back till late Monday with a one liner. Guess I need to spend more than just a couple grand there.

Sent you a pm if you didn't see it

Got it thanks.

Don't get me wrong he's a fantastic guy and hopefully I can get my truck to him once I get my trans built to do some tuning. Just annoyed with his frontline people.

Hmm, my modded reg. has never given me any issues tuning it.

It's the guys that mod them them selves and take it "too far". Doesn't take much for them to make tuning a pain...

I can assure you that has nothing to do with being able to talk to Mark lol.

I emailed him. See what he says.

Heard back from Mark. He thinks it might be tuning related to cold starting. I'm guessing maybe there is a coolant temp multiplier or something wanking me about?

 

[LBZ]

What should I be looking at for tuning adjustments? Pull fuel pressure ECT from the idle range?Base fuel? Adjust Desired flow vs coolant? I've never touched this area before. It's commanding 30-35mpa but is giving me over double that

Yes I agree. I made sure to only open the base of the triangle (wot only)

 

[LBZ]

Well fixed my fuel rail pressure finally with some tuning. The fix was adjusting Desired Flow vs Current table by adding 20% to the mA. Now I got more serious problems though.........
