Tuning for warmer air

[larrym]

Apparently my extender G chip does not use the air inlet temp sensor to adjust for changes in conditions.




my question is if the inlet temp sensor is not used what precautions should I take if race conditions are 100 plus degrees compared to my cool coastal environment say 85 to 90.
If I tune it to the edge at home how much should I back it down for the conditions in the valley, where should I make the changes timing or boost.

Hotter air should make you richer as there's less oxygen density per cubic foot of air.  The O2 will be providing feedback depending on what chip setup you have too.

I have Gen2 translator and extender g chip, I have the wide band correction enabled so my fueling should be ok.


So set it on kill and run the bag off it?

Hotter air is less dense, but hotter air tends to be more detonation prone.

I would not set my own car to kill unless I had enough prior experience to tell me how it should be tuned for the current ambient conditions.

Now, if it was your car, I might not be as prudent

Thanks Steve!
My new favorite quote "Now, if it was your car, I might not be as prudent"


So pull a little timing or a little boost?

[Steve Wood]

don't know how much timing you are running-so I would say drop the boost about 2 psi which will make the car richer...and start from there.  If you are running alky, then that tends to keep things cool and you may find that you can run what you were running or even go up.  Just watch the first run and let off if you see any timing retard.  People that are not cautious fix more "brokes" over their lives.

Keep notes of the conditions and how the car ran.  then you will build a history that will simplify your future efforts
