Tuning for the seasons

[TYTILIDIE]

Ive been tuning a lot here lately. One thing I have noticed, is htat things change considerably when the temperature gets hotter around here. I knew this would happen to a point but sometimes seems a little drastic. So heres my main question, am I bvetter off tuning for a burned chip in the summer time? Its been cold here for the most part. 30*-50*. Got the truck running really good. I am by no means even close to burning a chip, still experimenting with TP and tuning itself. I also had another thought, is there a table that would compensate for the temperature change? So i.e., if I dial in my tune in 40* wheather, instead of starting all over when its 75* and my tune turns into crap, can I just go to some magical temp related table and program it to change everything according to temps? I mean ambient or intake temps ofcourse. Also, I put my 160* Tstat in the summer time, should I just make a whole other chip for that? TIA for anyone who helps out.

You actually tune for both... this is where the MAT fueling table comes in, also the cold start fueling tables.

In general, you're better off tuning for the cold day, since things will get progressively richer as things warm up.

A good cal, however is one that operates well at 50deg and 90deg. Takes a bit of work to get there, though.

Re: Tuning for the seasons

I noticed my once near perfect BLM's and INT's have changed alot with the cooler weather, but I have also been messing with timing and letting the closed loop wide band take care of the rest.

I have really altered my MAT vs Timing table to take advantage of cool air, and offer overboost protection at anything much over 200 KPA.

I see, which table is htat? Is it F31M? And what exactly would I want to do with it? On kine it says *C vs. CTS? I dont know what CTS means.

Which table is MAT vs Timing?

I am not at home, but on my version of tunerpro its down at the bottom under timing. It should read temp in C on the left (rows) and KPA accross the top (columns). Most stock cal's have -1.76 degrees entered for for the lowest KPA fields. Hope that helps you find it.

F3 is the table I am talking about.
