Ultimate LS Injectors
I own a 95 GMC C1500 I have swapped a 5.3L LS1 into it i used the Fitech LS Ultimate induction kit #70002 I also have a 4l60E (HAD). The transmission tuning on the Ultimate kit is garbage and has already blown out three transmission with multiple calls to Fitech. So I went out and bought a Holley Terminator X Max system. To make a long story short it uses high impedance injectors and requires that I tune the system with them. Well I have called Fitech multiple times to get their parameters to be able to tune this system and they either come up with an excuse like ah machine is broken or just flat out refuse to give me the off-time data that I need. So question I am having is that either does anyone have that data or if you have swapped out the injectors what kind did you use because I have no problem swapping the injectors I just don't know which ones would fit.
Thanks,
Steven
The factory injectors work with the Fitech system. Not sure the issue.
Please keep the negative comments to Facebook or other Social Media. I know there are challenges and that is why this website was started. Here to help. There are many here that have been successful with transmission controls and would be happy to help.
I had a few issues with the provided injecters and call fi tech and and they took care of it with no problems you can use the factory injectors for 5.3-6.0 but will need adapters for plugs and as far as trans coltroll once you learn how to use it may take few calls or questions it is great this system is awesome and tech support is great help !!!!
