Temperature Compensation Not doing its job?

hardcorersxs · Post by **hardcorersxs** » Fri Dec 14, 2007 4:14 pm

I tuned a car and input different values for colder temperatures. Colder temperatures came, car started doing lean cuts. I had to do a seperate calibration due to several attempts of adjust temperature compensation tables.

1) Cold temperatures came in 1 week after tune was done
2) More fuel in the tables didn't make a difference.

Here's the settings copied directly from the medium to full throttle load air temp table.

IAT -22/40/86/175/208
Corr. 25.0/18.9/-0.9/-7.1/-9.0

If this following question has been asked before, please accept my apologies.

If IAT temperature is between 40 and 86 for example, does k-pro interpolate between the correction values?

I've tested the IAT compensation and it works ok. Yes, there is interpolation with IAT compensation.

That's weird, it isn't working on my customers car for some odd reason. I guess he has to use a cold weather calibration

sorry to resurrect this thread...BUT!

I think I am having the same issue, it seems to be ignoring the AIT

tested this by setting a VERY aggressive compensation table then dumping the AIT into warm water, ie. from 20C to 40C and yet the injection times remained the same...

is here some delay in the ECU reacting to the AIT?

Help!

OK,

looking at the temp compensation table, it say's it's in degree's F

is that correct if the setting in sensors is set to show AIT as degree's C ?

is there an easy way of telling what compensation adjustment is being made real-time (or from dataloggs?)

really need some help here please?

THe sensor list is sparate form the parameters. You must go to Options, Settings and Units to change the paramter units.

this I know, you go try it, it does not change...

if I open a cal file from the previous version, the table values are a mess...

edit...

OK, just updates to 1.2.3.1 and it works?

looks like something odd going on with 1.2.2.9 ?
