Hi,
can anyone share any reliable tuning website where i can learn the basic til advance ecu tuning?

Thanks

 

a user on here (r3compile) made a series of like 10 videos that are very informative. I beleive they are in the ecuflash thread somewhere

 

Google - Merlins tuning guide

 

Is this a serious question?

https://www.evolutionm.net/forums/ecuflash-179/

 

I learned everything that I know through this forum and the ecuflash section. Very good info in there, it just does take a while to read it all and understand it. Took me many many hours of reading and re-reading to understand most of it. And ya check out Merlin's guide it's pretty useful as well.

 

Thank you so much guys...Truly appreciate it.

 

Hi but which [art should i start?

 

Have a look HERE also.

 

1st http://www.enginebasics.com/

2nd https://www.evolutionm.net/forums/ec...-tune-evo.html

3rd http://evoscan.com/technical-vehicle...le-efi-systems

Everything in between. https://www.evolutionm.net/forums/ec...ead-links.html

*edit* and of course r3compile videos like silvermr said.

 

Thank you Guys...

 

The reason i open this thread is bcos my tune is slightly off after i changed to a bigger 340L fuel pump & aem fpr.

The low end response is bad as whenever i wot on 1st & 2nd gear my car just like dipping down and ive to slightly let the throttle off and re-throttle again only than it launch...My aem wb02 shown immediate 10afr when i wot.

My ride use to be responsive even on a g3076r with S2 cams...I can go over a bump with downshifting on my 3rd gear.
My high end power seems to improved with lesser knocks count from my pfc ecu.

Ive sent it for retune but no much improvement. i had tried advancing some timing but still the same.

Even my exhaust & engine sounded quieter now.

(The figures above is from my save map)

What should i do? Can anyone shed some light here?

 

you seem to be running very rich since you changed your pump and fpr. dial down your fpr to around 43psi. that should make your current tune work better.

also if it is tuning help you need i would suggest moving this thread to the tuning section.

 

Ive tried moving down my Aem fpr but the lowest it goes is still 3.7bar.

Btw can you interpret the figures i post?

 

Sounds like something is wrong with your (junk) AEM regulator and/or you need a bigger return fuel line. Fix this issue before you go farther.

Wrenching before tuning.....a forgotten art.

 

Thanks Travis but i believed the Aem fpr is ok but will do the bigger fuel return line...
