1:12 I did this step without holding down the accelerator to shut off fuel supply and it instantly flooded out my engine and fouled out the spark plugs. Now I’m screwed and it doesn’t wanna start anymore. Car was running fine before, I should’ve left it alone🤦🏽♂️. Any advice on how to reverse this?
You rewrote the calibration file. If anything the file is not correct for your engine. It could be that you selected the from reluctor file (24 or 58). It could also be the wrong injector side in the calibration. You need to go back through the initial setup in this case.
@@FiTechEFImedia yea I selected the same file in the video (24). I have a 5.7l 4l60e. I still can’t figure it out. We tried to do like a master reset and start from zero but still nothing worked😟 could I get you guys on the phone perhaps?
Thank you for this Fitech and Bryce, I'm almost complete with my project! It's always great to have support. *not crying over spilled milked but I noticed some misspellings in your instruction manual.* Hope I can be help from one quality person to another. Thank you Fitech!
Yes. You just need to turn on the trans control under the Initial Setup of the handheld. You may also need the harness if you didn't purchase it initially. Trans Control Sub Harness # 70050-5
I recently installed the 70050 on a gen lll 5.3 with a light cam/th350 trans. Im followed the initial set up on this video as much as possible. Questions : how to adjust IAC on cable throttle body? Mine jumps between 0-1 at idle. Also once at operating temp the engine stalls as I accelerate. Any ideas ? Appreciate the help if possible.
I put a LS1 fuel injected engine out of a 1998 Caramo Z28 in my old 1980 CJ5 Jeep. I tried for months to get LS1 PCM harness working and could only get a crank no start result. I purchased your 70050-1 Ultimate LS system and have it installed. I try to start the setup but get ECU no response when I try to enter anything. Any tips on what to check?
Your best option is to give our tech line a call or email. The most common reasons for no ECU response is missed or improper wiring of the system. There are two rounds on the harness that need to be grounded to the engine. Then engine also needs to be grounded back to the battery. We often see a ground being missed.
Pull the plugs on the cold cylinders and see if the plugs are wet. If they are dry the injectors may be clogged or stuck shut. If they are wet the check for spark on those cylinders. That could be possible dead coils or wiring connection issue to them.
@@FiTechEFImedia thanks man I've done just about everything,, but the engine only has 3 hours run time so I'm thinking I cleaned the cylinders. I'm gonna put oil in them and try again
here is where its confusing,,, I just caught that when you hit enter and it says sending to the CPU - its not saving it or is it, or do you have to turn the key off and on every time,,,
The Ultimate LS system provides a tach and speedo output to go to the dash. You will have to refer to the dash instructions on which wire those are on the dash.
Are you running stock injectors? I jus put a brand new fitech ultimate ls 70050 on gen 3 5.3 and 4L60 all stock In but after I tune my battery died if I don’t start every few days??? What to do?
We use FiTech injectors with our LS kits. The only thing that draws power from the EFI system with the key off is the handheld. If you unplug the handheld there will be no draw from the EFI.

What type of nitrous system do you recommend with the ultimate LS system. Wet , dry , plate etc
If you make changes to your vehicle like I’m running a 700r4 and want to switch to a 4l80 is it possible to change that

Where did you wire the key on to
@@MichaelBrown-kz9qk I have a switch panel and it all goes to it
I need some help, I've got 3 cold cylinders, what more can I do
Pull the plugs on the cold cylinders and see if the plugs are wet. If they are dry the injectors may be clogged or stuck shut. If they are wet the check for spark on those cylinders. That could be possible dead coils or wiring connection issue to them.

hitting enter "send to ECU" applies the change to the ECU. The key off cycle then saves the calibration including all changed made.
Can I see the miles in the fitech monitor?
Unfortunately no.
Well, I have an original 5.3 single turbo engine with an ultimate Ls injection system. How do I calibrate the IAC
Setting the IAC is no different with or without the turbo.
How do i wire my digital cluster do i need a adapter?
The Ultimate LS system provides a tach and speedo output to go to the dash. You will have to refer to the dash instructions on which wire those are on the dash.
@@FiTechEFImedia oh okay just making sure
Would this work for a humvee with 6.5 diesel

@@FiTechEFImedia thank you will check it out
If the lock up function is not engaged., it wont lug down to the lower transmission gear ratio for lockup at wot throttle correct???
Can you do one with the ultimate ls system with single turbo
Yes you can!
How do I wire up my trans brake?
You don't
325ce 5.3 not 425
325 not425 in
How do you set this up with a 4l80e…?
In Initial Setup there is an option to select the trans. In the video it shows the switching of 4L6XE or 4L8XE.
@@FiTechEFImedia I seen that, and also thought how would the ISS sensor work with this
