so wanted to start a discussion to figure exactly what people are pulling for timing based on iat. also what is there max timing in boost and discuss when they are pulling most of there timing. i know motors are more prone to detonation during spool up, and efficiency of turbo, intercooler, and general build vary greatly. im looking to get a general rule of thumb how much timing people pull for different iat we know as air gets hotter pull more timing air is less dense, greater chance for detonation. I feel i run a pretty thin line im probaboly pretty close to detonation which is why id like to know what other setups are running here is my current setup only going for info that matters.

b18c1 MId Sleeve, wiseco82mm pistons 9.0:1
mishimoto zline intercooler
turbonetics t3/t4 ceramic bb turbo .48h/.60c
boost is ranging from 8 to 20 lbs
Elevation 1600

at 10psi my max timing from 6000-8000 is 24degrees
at 100 iat i pull .5 degree timing
at 125 iat i pull 1.00 degree timing
at 140 iat i pull 2.25 degree timing
at 165 iat i pull 4.25 degree timing not like it gets that hot unless started after hot and sits. what do you think for timing am i on the line or over or under for timing, motor runs great but i want to make power safely

I think its 13 percent for every 10 degrees

Theres info online.

Learn to read your plugs

thats not accurate at all 13% of 10 would be 1.3 degrees. and makes no sense, generally speaking its about .5 to .75 degree per psi. The only thing i would use plugs for is rich or lean if i didnt have a wideband

<p>There's this awesome thing called searching. &nbsp;Try it next time. &nbsp;No two motors are the same.</p><p>https://honda-tech.com/forced-induct...boost-1373039/</p><p>http://www.d-series.org/forums/engin...s-engines.html</p><p>&nbsp;</p>

already viewed those there opinions no numbers and nothing on iat. no 2 motors are the same but if someone has a similar setup they could say what they are pulling at certain iat being as if you have a good tune and similar motor it would give good guidence for how much to be pulled. and i did try searching isnt much discussion being made for iat and how much timing from temp corrections should be pulled without losing to much power. one thing is for sure water/meth kits. then again asking for numbers not opinions. preferably from someone who has tuned there car

<p>You won't find solid numbers, because there are no solid numbers. &nbsp;Not every setup is the same. &nbsp;Hell, not even every motor is the same. &nbsp;Even more, not every tuner will tune it the same way. &nbsp;You just need to sit down and do it, or let a professional handle it for you.</p>

I think its every 10 degrees its 1 degree timing so starting at 70-80 degrees iat and up add timing and less than 70-80 pull timing

I gotta check my map

Plugs do a hell of a lot more than tell your afr

Bitch you said for iat temps wtf are you bringing up psi for?

turbonetics3597

touche but you never said farenheit nor did you specify at what temp you started pulling timing, my bad thinking you were talking timing

turbonetics3597

I think thats backwards pull timing higher iats and add timing lower iats

No

Part of me thinks this would have a better shot in the Engine Management section...

turbonetics3597

agreed, but the other guy needs to go back to tuning 101 dont even think he knows what controls ignition dwell other than ecu. Dont worry he will google it to find out. hint its part of the ignition system

turbonetics3597

you must have a great tune, most likely one you payed for
Like i said id rather use a led light hooked to the knock sensor than plugs.
Better yet a 10 ft pvc pipe touching the motor during dynos.
Just to correct you wrong you need to pull timing at higher iats why? google it kid your probaboly the one who thinks the bang is what moves the piston though actually it is the nitrogen after the bang that forces it.

Dude, take this to engine management, and argue there. This "discussion" is starting to turn into a pissing match. Get your DIY tips and debating done there.

And yes, I PAID for my tuning to be done, so that I DON'T getting to the debate. Damn proud of it too.

Not really, the only thing really going on here is someone continously spouting off their ignorance. If you disagree or show proof they are wrong, they will just keep on spouting nonsense until they "win".

All you have to do is look at the 3 more popular Honda based EMS out there - Crome, Hondata, and Neptune. They are free to download the software in each instance. Each of these retard timing as IAT goes up. When IAT is more "normal" which could be referred to as ambient, no compensation is required. If they are wrong, then someone better get on the phone STAT!
