Swamps 58V FICM Question
So I just bought a new 58V Swamps FICM (courtesy of tuckman) and installed it in my 2004. I visited with Swamps before I bought just to make sure on compatibility. Tuckman told me it had the PHP mild flash and inductive heating option. Whatever on that... I'm in Oklahoma, when it's cold, I plug it in anyways. Since I've installed it, my truck runs GREAT. Huge difference in response and throttle. Very smooth and silky power now. Highly recommend this upgrade to 6.0L owners who haven't already invested. Now, here's my deal with it: we've had a cold front come through and it's been getting down to 40's-50's at night. The past three mornings when I go out and start my truck to let it warm up (not plugged in), it starts right up after I cycle the glow plugs. Nice clean and crisp fire off with 48V reading on my CTS all the time now. But once I start the truck, it sounds worse than it did with my original FICM for about 45 seconds. It rattles and lopes a little bit, but it's not missing or struggling. Just sounds worse than it did before. After 30-45 seconds, it's like someone hits a switch and it clears right up and runs smooth as can be. I've not had any injector stiction prior to this. I run T6 and Motorcraft filters. Never had a cold idle issue beforehand, and I'm just wondering what I'm seeing. I may try and snap a video of it and post tomorrow morning when I start it up and show you guys. Other than that initial 45 seconds, I love this FICM.
I called Swamps today and asked them about it. They told me to give it a week and if nothing changes to try and reinstall my old FICM and see if it changes. He thought maybe my flash was not jiving with the PHP flash, but couldn't see why it would run great other than initial cold startup. I'll check back with them next week after I watch it some more.
Anyone have any insight they'd like to share with me?
