Hello to all Fuel Injected Gearheads,
Thank you all for taking your time, to get acquainted with my project, explaining things to me, advising and helping me!!!
A special thanks to:
Lextech, thank you for providing the wiring file for the swap of black box to 0411 PCM, that made the swap very easy! (I saw all your vids at youtube, all your swaps and upgrades of your truck, very nice, i realy enjoyed watching, and reading your posts!)
Scott & Hog, thank you guys for sharing your knowledge, information about tunercat, PCM, how it all works, and where it will all lead me to, deppending on what i choose, it made my choice very easy, and helped me to understand alot, gave me alot of useful information!
NISANDA, thank you very much for sharing the "2001 Truck 5.7 L31 4l60e 4x2.cal" file, I have used it as a firmware for my swap, and after performing the swap, my truck started imidiately with it, with no problem, so it worked for me for all 100%, thank you!
Now let me update on my project:
Just a few days ago, i have made the swap of my blackBox PCM to 0411, with Excel file from Lextech, i understood that i shouldn't have been getting ready to make this swap for saw long, i sould have just whent for it straight away, becouse it was super easy, i have achieved the swap just in about three hours.
With my Dell D620, where i have installed the TunerCat RT and uploaded to the RoadRunner the "2001 Truck 5.7 L31 4l60e 4x2.cal" that NISANDA have shared. The Truck started immediately.
At first it couldn't idle, it would start, rise rpm, then lower the rpm and shut. The second time, start rise rpm, then lower it, and i tapped the pedal, not to let it shut, and it would rise the rpm again and stay ideling at high rpm, I would say that at about 1500-2000rpm. Now every time i start the truck, i have it ideling at high rpm from the start (it doesen`t lower it any more, and doesnt shut), it just starts, gets to high rpm and stays ideling at the high rpm speed, after it warms up, it doesn`t lower the rpm, but keeps on ideling at high rpm. This is the situation now, that i have to sort out, and as well, have to learn how and what in the firmware file to program with TunerCat RT via RoadRuner guts, it order to tune it all correctly.
As well, straight after the swap, i wanted to re isolate the wiring harness, and found out that some wires in the harness were chopped, the list of chopped wires on the picture attached from excel file print screen. Those are wires that are chopped from PCM pin out side, there are a few wires on another picture, that are chopped and coming out from harness, but I doubt they linked to PCM, becouse i checked the pinout chart while making the swap, and had all the wires present at the sockets.
But the list in excel file, of wires coming from the pcm and being chopped, are the once i worry about, some of them can affect the PCM and engine functionality, like the Vehicle Speed Output to Brake control module, and the two wires of VSS for example.
My main brainstorming now, is about scaning, loging tool that i should get, the question is, should i get the Tech2, MDI, or HPtuner for these perpose? I would go with HPtuner and an ODBII cable, but will it have all the functionality as the Tech2 & MDI, will HPtuner be able to make a crank relearn? and falt reading/deleting, scanning and so on..?
As well, is their any howto to using TunerCat, well, not exactly using the TunerCat, i mean a howto to making changes to the firmware, I`m afraid to mess with the tables for now, but other changes thet i tryed to make in TunerCat RT to the firmware, like the IAC counts that i dropped from 310 -> 160, and noticed no result, at least it did nothing to the high rpm the engine idles at. And without actualy fully understanding what i`m playing with, i fill unconfident and uncomfertable making changes, due to worrying that i can brake something.
Anyway, thank you all for help once again, i will keep on stragling with my project, and if you guys have advice for me, i would realy appresiate it, since the information shared by you guys, and your advices, helped me alot before!
Thanks to all, take care!!!
