Ok boost looks much more controlled here.

Jump up to the next map- do 2-3 WOT Adaptation pulls & log the next 2 pulls after

If I’m already map 2, should I go back to map 6, or adjust 6 down to around 22psi? Or go map 7

Let’s see 7 first & if all checks out we can bump to 6 @ 22

[Wrecker 426]

Here are some logs, had issues with traction in 3rd, was a bit wet the first few times on the 10th, today it was dry

[Dave @ BMS/Fuel-It!]

Your LPFP is tanking- what are you using on that end? Your signature says stage 2 LPFP Walbro 525 2nd- ate you dual pumps or just 1?

Second pump is on a HOBS switch set to 12psi it the fuel it kit that adds a pump but retains stock basket. if it tanked it may not have turned on. I’ll have to check this

Yes- please double check, because that value is very very low

I’m going to go give it a pull or two see if it drops again, only yesterday it didn’t turn on. Then pull it in the garage and check wires, it’s wet again today so probably 4th gear pulls

Looked at a few logs, LPFP still tanking, doesn’t look like that 2nd pump is turning on.

Could my fuel lines be to small?

Is there a different way to trigger the pump other then a Hobbs switch? I bypassed the Hobbs switch and hear it turn on

Right now that switch it for meth and 2nd fuel pump

[Dave @ BMS/Fuel-It!]

Doubt the lines are too small

So your using your Hobbs for both meth AND your secondary LPFP?

Nope just LPFP, thought I had it on there but still using JB4 and FSB for meth, could I use the yellow wire for fuel pump? And what setting to tell it to turn on

External trigger menu- believe it’s under methanol settings

I personally prefer the Hobbs switch myself

[Wrecker 426]

Here is one that I disconnect the pump, another hard wired always on

[Wrecker 426]

Built this contraption and tested the Hobbs switch, also turned it down to 10psi in hope it will lead the boost a bit better, logs coming soon

[Wrecker 426]

Here are some logs, fuel really falls off above 6800rpm, only cause I’m a dumb a$$ and hold my foot in to long, still seems to be falling off, but no worse then at 28psi with the 7th injector going, should I bring the Hobbs down to 5-6 psi?

[Wrecker 426]

Here are some at 5psi on the Hobbs switch, same result, Could it be a fuel pressure regulator?

[Dave @ BMS/Fuel-It!]

Possibly... is yours OEM?

Pressure shouldn’t be plummeting, you have plenty of fuel

[Wrecker 426]

Yeah it only has 138k miles on it.

Was going to change out the voltage regulator. And see if that helps

[Wrecker 426]

Replaces the voltage regulator, seemed alright, found that my power cable for the second fuel pump was loose, looking at this it only dropped when I shifted, what’s a good number to keep the fuel above

[Dave @ BMS/Fuel-It!]

Still looks like it’s diving...

With dual pumps- I don’t see a reason why your LPFP psi should go much lower than the mid 60s

[Wrecker 426]

Having electrical issues, just put a battery in 6 months ago, thought I killed it, and hasn't been charging, got replacement battery under warranty. 70 out today and car barley starts, first start on the battery. so I’m going to put it on a lift check the grounding strap that supposedly on the drivers side, and if that good then a starter, shouldn’t bog with a new battery. Thought IBS also, but it was disconnected this time. This on top of having to travel for work means another month before I get testing in, thankfully I don’t need my car for that travel. Also found a document that says not to connect anything directly to the terminal due to IBS and that we’re the 2nd fuel pump turns on.
