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.

Re: Flex fuel sensor questions

Did any of the explorer 5.0’s come with flex option? I’ve never looked in to that. It’s been running with this ecu for some time now, but I never tried disconnecting that sensor and seeing if it did anything.

Flex fuel sensor questions

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? Ecu...

Re: Explorer eecv TC lockup problems

I have no clue what setting has gotten messed up to cause this. But this level of info is what somebody in the know would like to have. But even more importantly, can you post the tune and indicate what strategy the tune follows? So, took it back to the dyno, drove around for a bit and found out th...

Re: Explorer eecv TC lockup problems

Found out that a KAM reset is enough to get the TC locking up again properly how it should. I've noticed that my brake switch isn't unlocking the converter while driving like it should when the brakes are tapped. Also the TC isnt coming unlocked when going up a hill/ load is increased. I hit 3/4 thr...

Explorer eecv TC lockup problems

Having some trans issues now. Backstory is: '00 explorer 5.0 swapped ranger, built 347 stroker, SCT Livewire TS+ tuned by Gil at HP Specialities here in Vegas, built 4r70w; old torque converter started slipping/not locking up anymore. Lots of metal debris when builder dropped the pan, flushed it all...

Re: 2000 5.0 ranger swap questions about EECV

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...

Re: 2000 5.0 ranger swap questions about EECV

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 ...

Sorry for the multiple posts but keep trying other things and want to post the updates.

Re: 2000 5.0 ranger swap questions about EECV

Tested voltage from PCM for camshaft position sensor and ECT sensor, was reading .4v on the dark blue / orange, and wasn't getting a reading anything from the light green / red for the ECT sensor. Is that common? Maybe less than .1v?

Re: 2000 5.0 ranger swap questions about EECV

Issue was there before I changed the sensor and synchro. Seems like it only happens with closed loop enabled. Waiting for another open loop tune from my current tuner to see if open loop resolves it or not. Any reasons closed loop could cause it to throw the code?

Re: 2000 5.0 ranger swap questions about EECV

How did you line up the CMP syncro? Did you use the correct tool? Do you have the correct sensor? Some use a hall effect and some a VR. Turned engine over until old synchro had flag facing forward between the "valleys" (dropped it in at TDC #1 with facing straight forward once fully seated) dropped...

Re: 2000 5.0 ranger swap questions about EECV

If you have a passenger O2, then you should be able to keep the EEC running Closed Loop, and it'll simply fail to running both banks off the working O2. You'll still get a CEL indicating the failure of the Driver O2. Unless your strategy does something different, most strategies behave this way. I ...

Re: 2000 5.0 ranger swap questions about EECV

You've got bad power wiring somewhere. Could be lose or corroded connections. If it doesn't it again, leave the key on and start wiggling connections and wires until it stops. Points to check first? I tried shaking engine to body harness, no affect in idle while running. Also when it was doing that...
