Re: Can someone here help with a tune file to get my truck drivable?

Here’s some instances of the issues I’m having: Cold starts. Wants to die, sometimes repeatedly. Idles lower than it should (around 500rpm), almost completely unresponsive to throttle inputs, usually just causes it to die if you give it some throttle When warming up, ECT is reading ~160°, if I give ...

Can someone here help with a tune file to get my truck drivable?

Not sure if this is allowed, didn’t see anything say it’s not so figured I’d ask. I have a dyno tuner here in Vegas, really good guy. Been happy with his adjustments and work. He’s worked a lot on the truck tune and dynoing it some months ago, have had issues with TC lockup and unlock related to TPS...

Re: Upgrading wiring for fuel pump?

Yessir one in engine bay and one in the bed, I’m going to be moving the back one inside next to the subs to condense some wiring and clean some stuff up. Minimize amount of wires entering truck from back battery hopefully to only the two for power and ground. Going to set up a fused 10-12g 4 bay dis...

Re: Upgrading wiring for fuel pump?

Current carrying capacity is what I was curious about. With that voltage calculator thing you can set what % loss you want and what length would keep it within that percentage.

Re: Upgrading wiring for fuel pump?

Using a few different wiring gauge calculators, it seems a 14-16ga wire that’s extremely short can withstand quite a bit of amperage @12v. Seems like a 14-16ga wire would be unsuitable to a 30a max pull is if it’s 2ft or longer. Here’s the one I was using, curious if you guys find it accurate in you...

Re: Upgrading wiring for fuel pump?

That's nice that they actually give a molded plug as opposed to the spade connectors. As a general rule, I don't trust spade connectors...but mostly that's only due to my experience with the cheap ones. The quality that manufacturers would use are designed much better and don't fail the way the che...

Re: Upgrading wiring for fuel pump?

I get not wasting money or time, but you are talking about a 800hp build. This isn't a place to skimp. Do it right when it comes to getting the fuel from that pump to the engine which includes getting the "angry pixies" from the battery to the pump. The only part being “skimped” really is the 2” of...

Re: Upgrading wiring for fuel pump?

So that’s a definite on having the stock system trigger a dedicated relay from my back battery to provide a dedicated 12v to the fuel pump. Will have a fuse on trigger wire feeding new relay. I’ll grab some good 12ga so it’s not as much of a jump from new positive wire and stock that’s fed through t...

No I am not familiar with a ranger fuel system.
No worries; cgrey answered my question about if the ecu modulated the fuel pump or not and it appears it doesn’t. Makes the secondary relay option more feasible.

Re: Upgrading wiring for fuel pump?

Well I’m running a 98-01 ecu in my ranger so I assume it’d be the same unless there’s hardware between pump relay and rear harness connector which all I saw was the inertia switch; and yes exactly, the return was from the fuel filter and regulated to 350kPa internally right next to the pump. What wo...

Re: Upgrading wiring for fuel pump?

Plan is 750-800hp on boost. Want to have more than enough and be sufficient for that level on e85 as well, and since the regulator will be boost referenced, I’ll be running more than the 60psi setting when hard into boost. I’ve had the same issue with my walbro 255 pump in the previous build. Quarte...

Re: Upgrading wiring for fuel pump?

Are you familiar with the fuel pump style on the rangers? Does the ecu run the pump at different power levels depending on situation or since this was an internally regulated “returnless” system, did it just run at a constant level? Suitability of current system seems plausible, it’s fused for 20a, ...

Re: Upgrading wiring for fuel pump?

It’s starting to sound more like I should just add a relay at the rear battery that’s triggered off the stock fuel pump positive wire. I could be mistaken here because I haven’t had a chance to verify yet, but I believe that fuel pump + wire leaves engine fuse box, goes to cab to inertia switch, goe...

Re: Upgrading wiring for fuel pump?

Find out what current draw that pump will have at highest gauge pressure. Look at existing wires sizes, terminal ratings and relay ratings end to end. It'd be pretty violent offroading to trip the inertia switch! According to Walbro webpage the 450lph model draws 15amps at 60psi @ 12volts(engine of...

Upgrading wiring for fuel pump?

I’m about to be running a Walbro 450lph internal pump in my ‘00 ranger build, and want to run a 10gauge power wire to the pump from my back battery. Seems most logical way would be to intercept original power wire after the connector that’s before the pump lid, send it to ignition terminal of a new ...

Re: Flex fuel sensor questions

So, then, there shouldn’t be any adverse effects to unplugging this flex sensor correct? I wasn’t sure if it was tied in to anything body side that would maybe cut fuel pump voltage if the connector wasn’t satisfied.

Going to be upgrading the fuel system soon on my build, chassis is a 2000 ford ranger 3.0l flex. If I get rid of this flex fuel sensor (will be running -8an lines from pump to fuel rails) since the flex fuel wiring connector will be disconnected, will this cause any problems with running/tuning?

I hit 3/4 thr...

The single wire sensors are only for guages....they don't go back to the ECU so dont worry too much about them. I'm sure I've seen the resistance vs temp specs somewhere for fox mustangs. Might give you a general idea if you can find them. Even then the guages are rarely accurate. John When I first...

Set your meter to Hz and make sure it's switching. You could also try measuring AC voltage if you don't have a meter with a Hz option. If it's not switching....and you verified wiring ...you likely need to verify that the sensors physical position/gap is correct. I didn't read the entire thread so ...
