Throttle adjustments should be independent of VE and fueling changes expect for maybe transients eg tip in. The LTFT's remain above 10% in that...

If those are the logs from the FIC660cc injectors based on the ON3's tune, then it is wayyy off and you really need to get it retuned properly. Do...

What did Dodgeboy say about the issue?

Relative pedal and relative throttle voltages are the key ones to log as they show the actual pedal and throttle body voltages that line up with the...

thats because you need to make and write a base startup tune, and dial it in from there.

Page 2 has your wiring instructions. I have used the serial connection with good success so far. Just buy a cheap serial to USB adapter on amazon and...

Probably has a pressure sensor input to use the analog output from the gauge. Connect analog gauge output to the sensor low reference and the analog...

Ok reg on the rail and vacuum line attached? Factory truck rails, basically. Injector P/N?

MAF is deleted minus the two wires for the IAT. No rear O2s, or AC. The rest is untouched as of now

Any unused 5v sensors on the vehicle?

Sent you a PM

Sorry, no not two regulators. The regulator that used to be in the jeep fuel pump has been pulled and bypassed. So just the one regulator on the rail...

I was wondering if I needed the Prolink for that. Thought I would see if I can hardwire it into the truck somewhere before I ordered it

I used the HP Tuners Prolink

Ok sorry for the delay with my response wife and kid stuff got me held up. But as far as the gen 4 crank I did swap reluctor wheels around. Also...

Is this a one-time-only thing where it would be perfectly fine to borrow service info from somebody else, or do you plan to DIY your own EFI...

Still the stock rear mount sensor. I will lookup the diagnostic procedure, I followed one I found on a forum earlier that ended with checking the...

Not able to follow this. Do you have two regulators?

Have you used the gear and tire wizard? Have you looked at the BlueCat tool software?

You need to post the wiring diagram you are working from for more feedback on what you should be measuring.

I think you should follow the diagnostics for P0342/P0343. Either one will find the problem, they're almost certainly both being set by the same...

Here it is

This is awesome. Can't believe you guys found the issue. Please post up some pics of how you installed the dsx flex fuel kit!!

Stock 1998 Jeep Wranger Fuel pump with pump regulator bypass to boost pressure to rail. Stock LS fuel rail and integral regulator + fuel return line....

46psi is still low of pressure, those truck from the factory would have run between 52 and 58psi. Like I said before, if you want to log it, you...

I can get the stock tune from the car but I can't get to idle long enough to get good data.
