Adding power

[maxxflip]

So i want to add a little power to a tune i already have...
Whats the best and safest way to do it??

Ultimately a good dyno session might reveal a few details.

There is usually a performance gain of ~ 2-4 % increase in HP/TQ by just finding the ideal AFR at WOT..I.E. 12.2-12.7.

Eliminating knock retard, finding the right WOT spark also helps. There are numerous fueling and spark parameters available through EFILive to maximize your tune.

That 2-4% increase worked out to be about +15 HP/TQ throughout the entire power curve on my vehicle. It responded the most to leaning out the AFR at WOT (12.7 AFR).

Hope that gets you going..

Ummm its a diesel :)
thanks for the thought tho :cheers:

I don't get it??

What does that matter?


Ultimately a good dyno session might reveal a few details. I agree but am not at the poimt i need to dyno IMO

Not tring to be a smart ass, those are great sugestions for a gasser

AFR is a factor in HP tuning but it's no where near 12.7 for us.

where were those posts from?

It was my mistake on the post. I missed the forum identifier, so when I saw the OP had no responses to his thread, my intention was just to get some basic information out and help his post.

I apologize for any confusion. I deleted my portion of the thread as it simply did not apply to the forum topic. It was not accurate or applicable.

Rather than start a battle, I will just simply say..I apologize. I made a mistake, and posted in the wrong forum. It was better to delete than post up wrong information.
I'll stick to GEN III from now on.. Thanks for understanding (I hope)..:cheers:

Hey, no problem man. I think ive got it figured out anyways. Just a few thing in my tune left to figure out.
Thanks for trying to help :cheers:

do you have any specific questions? sometime hard to explain the entire process of adding power...

a really handy tool is to download some tunes out of the tune library @ dieselplace.com and use the compare tune function in the tune tool to see what other people have done.

Be careful though only download tunes that have recieved good reviews. Sometimes newbs make a dirty or dangerous tune and post it up without knowing what they r doing.

Whats the main tables i should be looking at for adding some power?

Im guessing PW and timing are my main concern for now, but im not to sure...
If i bump PW width up and use josh's timing calculator for timing adjustments
is there anything else that needs to be adjusted with those tables ?

I know about the limiting tables but those dont seem to be affecting me at this point...

Im not confident enough to be able to look at those tunes and know if there safe to use or compare to

PW, timing, pressure, boost.

increase PW gradually
increase pressure
timing; Josh H's timing V3 calculator is awesome because you can enter cell by cell the % of timing you want.
increase boost a couple of pounds. dont boost above 30-32 PSIG @ sea level.

bb, as you increase those gradually, what do you look at to know when to stop increasing? :)

Where can I get Josh H's timing V3 calculator

There ya go:)

Thank u DmaxHawk

well you know that 30-32 PSI on a stock turbo is pretty much the safe and efficient limit. and stop adding PW when your actual rail pressure can match what the tune is calling for. and timing... use josh's timing calc. more timing will decrease EGTs and retarded timing will increase EGTs. icreased timing will also clean up black smoke too but too much will cause ignition too early and that is BAD NEWS for your engine.

thanks!
