oh boy. this is why i shy away from electrical stuff. Confuses me every time as I have 0 knowledge in the field haha. Okay so The tci Recieve and Transmit wires should not equal 5 and 12v yet they should add up to around 5v?

OBD diagnostics
So i just prode pin 4 or 5 and test the tci wires for 5 and 12 volts?
-
OBD diagnostics
So I should do test tci wires against chassis ground pin instead of signal ground pin?

OBD diagnostics
I got the battery cables off the 2002 truck aswell so I guess I could swap that cable into my truck. I will start my venture of wiring tomorrow when I get time.

So a smarty uses the tci wires to flash the computer. The signal wires are connected to the PCM. Is there a ground for the pcm that i can clean?
-
OBD diagnostics
So Do i use the signal ground or chassis ground to test the sci pins? Im sorry for my very simple questions. I dint mess with electrical very much.
-
OBD diagnostics
OH okay sorry for the silly question. Which pin is the ground so i can ground out my volt meter to test voltage.

OBD diagnostics
what are the rx and tx circuits? So I was correct on the smarty does use the sci transmit and sci receive wires to flash the computer. So I can hook a normal scan tool to the truck and it will read data and clear codes. I cannot hook the smarty to it and read codes or flash the computer. So My sci wires will support low rate but not high rate programming. how do i go about diagnosing this?

Okay so does the smarty use the sci transmit and sci recieve to install the programming? What pins does the smarty use to flash the ecm

Does anyone have any info about the pins on a 1998.5 OBD port and where the wires go. I.E. Where the chassis and signal ground go. Im trying to diagnose a faulty smarty cable or faulty obd/truck wiring. I have a 2002 ecu and a rebuilt 1998.5 ECU. I purchased a flash file from smarty to flash the 2002 to my 1998.5. IThe smarty would connect to the ECU while it was connected to the 2002 donor truck. IT wont on my truck. It wont connect to the 1998.5 or 2002 ecu while on my truck. I can hook my scan tool up to my truck and it will connect to both and read codes on both? SOOOOO I think something might be wrong with my obd port.

1998.5 Truck Build Questions
The second one you can kinda tell but you gotta pay close attention. ill probably just stick with the 2.5 lift then and pick up a set of 18x10 or 18x12 with 33s

That last part is somewhat true. The location where the spare exited the vehicle is unknown and has been since November of 1999.

1998.5 Truck Build Questions
i can get a 2 and 3/4 leveling kit instead of 2 and 1/2 for a couple bucks more to get it completely even. Im gunna go to walmart or somewhere similar to make sure my measurements were swayed cause of 35 year old concrete. i want a level look while unloaded. If squatting while towing is a bother to me I will purchase leveling air bags and a compressor to throw under where the spare tire vanished from while on the interstate to little rock.

1998.5 Truck Build Questions
I just measured it out of curiosity. And from my very rough measurements on my concrete pad which isn't level after years of use the back is 2 and 3/4 inch higher than the front.

1998.5 Truck Build Questions
i have 285/75/16 hankook dynapro at/m right now. they dont rub at all. so 18 or smaller with 9 or skinnier tires and smallee than a 35 is what i should get I was planning on doing a 2.5 leveling kit. So will the .5 inch of lift be too much for stock axle location and therefore cause me to have to get the longer control arms to relocate my axle forward a .5 inch or however far they push it forward to center it?
-
1998.5 Truck Build Questions
So I can get a leveling kit but will need the longer control arms to relocate the axle forward. Or just take out the over load springs to reverse level it and then get the control arms to push the axle forward to clear 33s on stock ride height

1998.5 Truck Build Questions
So basically i need to scrap my enitre plan to kinda spoof up the truck a little bit or have to buy new gear for the differentials. Ill have to put an entire new braking setup. Ill have t put a long arm suspension setup as the short arm setups ride like crap. Ill have to make even more hp which will in turn make me ave to get an even bigger clutch. OOOO boy haha this sounds like thousands more than my initial estimate.

strange noise and oil leak
I would love pointers on how to fix oil pan gasket leaking. My front cover, tappet cover, and oil pan leak. Brand new rear main seal 1000 miles on it or so. If I get the oil pan gasket to stop leaking I might get an itch and want to fix the other 2 leaks aswell. ALSO, What can I do with the front case vent to stop it from dripping on front axle?

1998.5 Truck Build Questions
I would fkash it myself but I just tried flashing my smarty and it fried the smarty. I don't want the same thing to happen to the quadzilla, aswell as the tech said they will honor my warranty if they do the upgrade

1998.5 Truck Build Questions
Goals for the truck are to be able to turn it up and show a few mustangs it isn't just another diesel while still being able to drive it around everyday and get decent mileage for what ive got done to the truck. Needs, well I pull a menagerie of trailers. Anything from 10ft bumper pull to 32ft gooseneck with hay or a 28ft stock trailer loaded down with cattle. I have the quadzilla and the tech at quadzilla said to ship it to him and he would update it to v2 tuning fro free for me. Im currently putting a new ecm on the truck from a 2002 so the smarty will be used to flash it to work with my truck. Technical difficulties happened and now i have to ship the unit to mads to have it fixed. I want a truck that I can drive everyday and be proud of and maybe catch a few people taking a second look from time to time haha. Chris at DFI recommended the 7x.011 sac after I told him what I wanted. Concerning the clutch. I am honestly dissapointed in the clutch as its a 500hp 1000ft-lb club and with the quadzilla by itself set on level 8 in 3rd 4th and 5th with the turbo set to 40psi and the programmer on 70% backdown it will spin the clutch for a solid second if not a few seconds.
