ficm tune issue

[borsky4]

So I finally got my 155 injectors gogo and batmo installed, loaded up a new tune from vivian, and wow did that bring it back to life. Only issue is low fuel pressure at higher rpm's. So I fihure ill pull the ficm tuning untill i get the fass installed and that migh help. Well turns out with the innovative ficm tuner you cant go back to stock. So I ended up reflashing to the performance flash, anyways afterwords start the truck and its missing, so I check the codes and get P0262 injector circuit high cylinder #1 and U0306 software incompatible with ficm,

Do I just need to reflash the ficm back to stock? Or could this have actually caused a problem with the circuitry on cylinder #1?

This might be a dumb question, but did you pull the FICM relay before flashing the FICM? The reason I ask is because my PHP Gryphon FICM tuner came with instructions that stated like 100 times to make sure to pull the FICM relay before the flash or you WILL cause damage to your injectors. It specifically list the #1 injector.

It shouldnt have caused a circuitry problem as long as you pulled the relay when you flashed it.

If its true you cant flash the FICM back to stock with Innovatives tuner that sucks

You screwed that injector, youre supposed to pull the ficm relay when flashing the ficm. A local kid did this not long ago.

Hmmm i never had to pull my relay when i tuned my FICM from ID a while back. There was never any instructions that said to do so. Truck runs fine. If you bought the tuner...then the stock FICM file should have been stored on it and you should be able to redownload the stock FICM file back onto it. It's the same concept and using a SCT.

ya i screwed it, there is nothing on the tuner that says to unplug it. Innovative says in the instructions it says to unplug it but I cant find them anymore. And I cant find a way on the tuner to go back to stock like the sct. Maybe ill try get it tonite, and change the injector coil too...

Three people I know of had issues with Erics device, and one with PHP's who didnt want to follow directions that were included. Ford calls to pull the relay when flashing the ficm. Wont ever catch me not doing it.

I've flashed probably 40 trucks at PHP events and Bill has always drilled me to pull the relay. I've heard him say again and again that it'll screw the injectors if you don't. I always pull mine.

pizza pig is correct we have to pull ficm relay when ever we flash and the reason is simple. when you flash guess whats on full duty cycle!!! yep the injectors when the relay is in and man do they get hot!!!!!

i had inovatives and also own a php and both say over and over pull relay when flashing!!!!

well lesson learned... I changed out the solenoid on cylinder #1 and shes back in action.... good thing I still had the cores. Casserly was awesome too said he'd ix it for me if i sent it to him free of charge! long haul to ship them back to tennesee from canada though. He just told me to change the solenoid cause they rarely fail under normal conditions. So thats what I did 3hrs and 15 mins and some bloody knuckles later and shes good to go
