Which map for idle fuel? - EvoXForums.com

Dreamer666 · 09-09-2012, 02:28 PM

Hi.
My idle has become restless. Fluctuate between 750-1000 when stationary.
And my ltft is -9 or around that.
Can I tweak this in some way?
Anyone seen similar?
Or knows something about it?
Using Cobb AP....

you need to rescale your injectors

HappyMint · 09-09-2012, 05:06 PM

Or the MAF should be rescaled.

What intake and injectors do you have? What AP map are you running (if any)?

First off if you haven't actually changed parts look for a vacuum or boost leak. If your FPR line has popped off or a vacuum line on the manifold etc then your car will have issues.

More info...
Car runs fine exept idle... Both at wot and cruise
No changed parts except TBE with HFC and Hks hybrid panel.

Runs a custom map that uses the same fuel map as stage2 95 v200.
Just tweaked boost and timing

Before popping in the HKS my LTFT at idle were about -3 to -5 but now it's down to -9.x
Shouldn't Hks let more air in? Elevating my LTFT closer to zero again? Or am I lost?

Will check vacuum line when I get home...
Tnx for help guys!
Any other ideas?

Cobb should have an off the shelf map for the HKS drop in. Download that and copy the MAF scaling values into your current map and flash it. There may even be threads with the scaling for it somewhere on the forums.

As long as that is the problem it should fix the issue.

Ok.
Haven't seen a OTS for drop in filter, will look more closely!
Wich map should I copy?
Shouldn't a less restrictive filter cause the car to have to ADD fuel?
Cruise LTFT is 0.8
Only idle that is screwed up -9.x. The minus part must mean that the car is removing fuel.....?

That's a pretty funny list for "no changed parts"

There is a map for the HKS filter on the cobb stage 2. I ran it for awhile with no issues.
