Fast355 - I see you have tuned Nissan/Infiniti OBD2, have you ever messed with a 2002 Q45 4.5L V8? Mine won't idle under 1300RPM any more. I don't want to step on this thread, maybe I should start a new one?Not trying to brag at all but I have tuned many platforms and I try to learn more all the time.

Hello PlayingWithTBI, " I don't want to step on this thread, maybe I should start a new one?" - As you wish, but personaly i don`t mind you using this my thread, as long as it give you help & result!Originally Posted by PlayingWithTBI
I won`t be any help thaw..
When you say it won't idle under 1,300 rpm, do you mean it idles high when warm or it stalls if the rpm drops under 1,300?
The closest I have played with to that setup was my 2011 M56S.

Thanks Aksl
Fast355, sorry for the confusion, it idles at 1300 and won't go below. I've changed the TB with a used one, a new PCV valve, sprayed contact cleaner all over, nothing. My son checked the codes and, aside from the both banks cats codes which I've had for some time, it says TB position (or something like that).
If you can get the actual code I can probably pull the vehicle specific Nissan diagnostic procedure for that code from Infiniti Assist software at work.
Thanks, it'll be a couple days...
Aksl, im NISANDA the one that send you the file, and its from a Silverado 2001 with the 5.7 vortec not a Express Van, in mexico there made 5.7s with the gen3 411 PCMs.
The file i send you its all parameters Stock (air,fuel,timming etc) except for Vats delete, Rear 02, EGR, EVAP,Cats and air pump delete. (the basic for start up swap).
This file i attach its basically the same but with idle adjustment to get you closer to you cam, some timming added and some more parameters adjusted to get you closer, try it and do a compare with the stock base file to see what i tweak in it.
Hope it helps.
Hello NISANDA, it is nice to hear from you again, thank you for the .cal file you have provided me earlier, and great thank you for the update, really appreciate!Aksl, im NISANDA the one that send you the file, and its from a Silverado 2001 with the 5.7 vortec not a Express Van, in mexico there made 5.7s with the gen3 411 PCMs.

I will compare the files today, to see and learn the difference, i will as well be going to my truck today, and going to test it, will try uploading the updated .cal files, will see yours, and as well will compare the .cal that i have udated with Fast355's help...
Thank you very much for your help!
Sincerely!

What cables are you guys using for data logging, is there any special feature, or chip, or is it just with support for "J1850 VPW" standard and thats all?
I will be going to my truck today, will try to upload the newly made .cal files i have, and will report up on the result tonight. It`s -20șC today, but with pedal applied by ± 20% the truck starts no problem at even lower tempreture.
