The problem with a basic tuning procedure is that everyone likes to have a different approach. What I like to do may not be the best way, but it works for me.

Go here:

Then look through this:

Then read some of this:

Have a trawl through that. The How To section on Romraider is pretty good as there are a lot of newbie questions on there.

UPDATE 4/8/2014:
Just a quick update on the information that have been given by forum members and how I have been implementing them. This is not meant to serve as a means to an end guild. If you choose to follow these direction to tune your car, you do so at your own risk.,,^_^

*If there is enough request for pictures with instruction then maybe i'll do some step by step picture tutorials.

1:I used romraider to advance ignition timing: Romraider along with the required FRS XML definition can be downloaded from http://www.openflashtablet.com/produ...ads/index.html.
By adujusting base timing B under ignition timing-Advance around .5degree at a time and log for knock. Caution:you should leave base A alone as it is the fail safe map. I've been able to add on around 11hp over the stock OTS maps, of course these whp that I've logged only on Virtual Dyno so I can not guarantee the accuracy of the VD compared to a real Dyno, But my logs are done on the same HWY (very dead Hwy) and I'm only comparing my original stock ots tune of 169whp to the 180whp VD readout that I got from logging.
tip: so far I've been able to advance up to 2.5 degree with minimal MAF scaling.

2:As far as the adjusting the AFR, it appears that the fueling-Primary Open Loop that I was doing didn't do much. so I just reverted back to stock setting. haven't tried to adjust the closed loop fueling yet, but I will probably mess with it in the future if needed,<-this should yield better result since the closed loop runs off the o2 sensor.

3.adjusting MAF scaling will be updated when I can come up with a way to do it in layman's term.

So far that's all I have been able to gather, as more information becomes available to me I'll try to update it, also if you see anything that is inaccurate, please let me know so that I can revise this post.


-------4/5/2014-----------------------------------------
I have no previous tuning background so
Just to clarify, what exactly am I suppose to log with OFT?
So far Ive just been slowly leaning the arf and advancing the ignition timing while keeping an eye on my logs for knock but I'm not sure if I'm looking in the right places. Seems like adv multiplier is always at 1 no matter how lean i get...does that mean that it hasn't detected knock and haven't pulled timing yet? So it should be safe to keep advancing? 2nd.ly KC correction is always at 0 degree. While KC learned only jumps around when there's load. .which i believe it's normal.

Just wanted more insight on what you guys are doing and what are your procedures... and if what I'm doing is correct .
I'm not looking to be a professional tuner, just looking for basic tuning diy procedures. Thanks in advance

And yes I'm aware that theres an official thread here http://www.ft86club.com/forums/showthread.php?t=46468
