LNF Guides

[cobaltssoverbooster]

Hoping this will become a sticky for LNF since we have so many great threads that have fallen to the dark and we keep seeing questions about them all the time.... im on the forum alot so as new developements arise i have no problem adding the information to this first post keeping this up to date.

***Information can be interpreted different ways between readers so as usual ask questions in the appropriate thread to clear any confusion and calibrate at your own risk!

Optimum Spark Tables / Torque Management (Read and Adjust at Own Risk!) GMTech
http://www.hptuners.com/forum/showthread.php?t=39660
**These tables are powerful and important to the lnf. If you get carried away on these tables, the side effects can be odd or flat out unsafe. Adjust these at your own risk. It is highly recommended by many community members to have an high level of understanding in regards to table effects within the ecu. It is most often the case that one table is not just making a single change, but it is also effecting 2 to 3 other tables as well. It will be easier to understand the Opti Spark/Torque tables after practicing and learning the table interlinking effects with the more basic tables.

Wow.... Just wow.

Some of the links above need to be fixed. If they contain ... they don't work. Good job though.

[cobaltssoverbooster]

haha ur definately old.....
i tell you what though i will color the links just for you 8D

ohnsetly its nice to have all the info in one accesible spot....also its not crowded with config files....although if we had a thread for lnf config files or custom histograms repository thread for lnf where everyone could see how we look at cams, ignition, fuel, and all that goodness. it would be a nice add to the list of threads.

[Iam Broke]

Try the 'Ethanol Fuel Blends Thread' link above before you call me old. Iz invented the interwebz before you waz borned, young'un. Back then we used BBS & 300 baud modems.

None of them link directly in Chrome, can't even paste that one in with the dots in it.

[cobaltssoverbooster]

wow i definatley did something wrong lol.
maybe im old...
alright urls are linked test them out

[CDNITE]

Links works for me in Chrome.

Thanks for putting this together, and also thanks for everyone's helpful replies!!

I've got some more threads starting soon on other tables, please share on those too.

[cobaltssoverbooster]

yep ill track them

[Iam Broke]

This one's still broken.

Like I said, the ... in the link kills it.

[cobaltssoverbooster]

[cobaltssoverbooster]

[Iam Broke]

Works now here.

[ericemir]

This is amazing!!! I want to thank all of you for the past week I was doing research and bookmarking all I could find on the LNF to do reading. Just purchased a Sky RL a month ago and got my HPTUNERS in.

You guys saved me so much time Big Thanks!!!

[cobaltssoverbooster]

updated
added ethanol belnd calculator
use the link and the lowest chart on the website tends to help the most.

[silverbullet08]

Ive got two major break throughs I discovered today. Il have you add them after I get some time for a write up.

[LNFnewb]

This is probably going to be my bible for the next few months. lol Great post!

[Tstonee]

Now something like this for the LSJ!

[cobaltssoverbooster]

Updated this today....
Im still watching the LNF VE thread grow to make sure its a proven calibration technique for the lnf.

also if anyone wishes to help with the videos for the LSJ Platform i have some time again and wouldnt mind giving all the credit to someone who can help me hunt down lsj threads and refresh my memory for tuning them to help this go faster and be more accurate. i openly admit its not my strongest platform so help on this will bring a better end result.
Thanks

[40rty]

Awesome, thanks for the info.

*update: add Aftermarket Turbo Section

Request: If anyone with a Aftermarket Turbo wishes to help the community we could use a thread to help with what to expect when tuning for different turbo swaps and if you ran into a rare problem what happened and if possible what was causing it.
Turbo Chargers Currently used: S20G-ET / BW EFR (ZFR) / S256-ET Bullseye Power/ Garrett GT/GTX series from 2876r-35r
if you happen to have a holset or turbonetics we'd love to hear about those too!
