Tuning Conditions

[Newbie GT]

Guys a thought

My way of thinking is that you would benifit for to retune twice a year with same mods.. Why?

Winter conditions vs summer conditions

Maybe secure the battery better? If you're finding you have to retune your radio so often

That's the dumbest statement you've ever made Alexi

Think about it we get tuned in summer 28 deg plus

Then winter 15 deg near abouts...

Wouldn't there be a factor there with tuning configurations

Maybe you should get 35 seperate tunes and put a dyno in a temperature controlled room. Then get a tune for every 1 degree between 0-35.....

That's the beauty of ECUs as opposed to carbies. The ECU takes changes in intake temp into account and adjusts accordingly to maintain the correct AFR. You are correct in your thinking that intake temp effects the density of the air and the cooler it is the more potential power can be made. This is why your car feels a little stronger on a cool winter evening as opposed to the moddle of a 40+ day in summer. Where a summer and winter tune would be of use is when you have summer and winter mix fuel. Winter mix has additives to stop the fuel freezing but unless you live in the high country and drive a diesel it's not something that we need to worry about. It could be something diesel Outback/Foz drivers could be interested in but I havn't seen too many of them looking for tunes.

Maybe you should re read the question
When logically thought about it makes sense ie a winter tune with same mods and a summer tune with same mods

I'm talking road tunes more than dyno

Please explain how that is a dumb statement?

Temperature doesn't affect your radio tuning, it's the power connection to the radio. Maybe your battery is old?

Ignored . Don't flood thread

You are aware a decent tune will take into consideration intake temps.

I am now

As countless individuals have already said, the ECU can automatically correct for different intake temps, negating the need for two tunes.

Semantics but that would make it 36 tunes

I'm aware of that now

However.
AFR is one thing, but boost and cylinder pressure is another. And that is what is killing our EJs.
Tune in summer for 24 psi..come those 2 degree nights in winter and it will be spiking way past 24. AFR will stay at 11:1 (or whatever) timing might be pulled depending on your tune, but I think the cylinder pressure might be off the charts. I know what ECU's should do, but I like to assume the worst is going to happen.

I think Newbie asked a valid question here.
In your vf52 too case Newbie I think you will be okay. People with big boost high HP tunes may need to consider it. Only because ej257/55s are fragile pieces of shit. Mick and Sean will be okay with their 13mm thick stock bores.
