Yeah in the airflow tab>Dynamic airflow,
Set enable to like 500RPM & disable to like 600 RPM

This will force the car in to a trust MAF only, to force it into Open Loop I have to look at the program I cant remeber it off the top of my head, been awhile since I have done MAF tuning on my car.

 

he asked the same question on hpt. should answer him there too, that will make sure he sees it!

btw...fred and i (mostly fred) worked on the tune some more on Thursday. It's pretty well dialed in, but we still get the lean spike just before going into PE. I'm going to max out the enrichment rate at 2.0 just to see what it does...currently its at 1.0 and we still get the spike for a split second. The hesitation is driving me nuts. It's the first e67 he's seen so it's possible we are missing something. Any ideas?

 

thank you so much!!

 

You can run in open loop by disconnecting your stock O2 sensor.

 

Will the no lift shift mess with rev matching down shifting?

 

Only if you are trying to match a rev over the 4000 RPM rev limiter.

 

HPTuners and a laptop

 

Damnit, I cant post any more pics for the how-To

 

i can host. email me at patrick@negmsc.com

 

It's not a prombelm hosting the pics. Its I can not add any more to the first post.

 

oh gotcha. pic post limit. maybe a mod can force them in.

 

What if any ammount of knock is safe? Ive heard of some being ok for 4 cylinder engines.

 

Knock is knock it's not good. But I start adjusting the HO table if I am getting over 2-3*'s

 

this is awesome

 

I take it you have never seen this thread before

 

no sir.. im debating on buying hp tuners.. wanna email me a file or something or make a trip up to pa lol

 

Buy me a plane tiket up on a Tuesday I can tune it on Wed and fly back on Thursday and yeah. Heck Id cut you one hell ofa deal if you did that. I would be able to visit my sister in Allentown

 

im game man i searched tickets its like 200 for a plane ticket

 

so 2-3 is acceptable?

 

Me personaly I dont sweet it too much. Others may, but from my research and my logs 2-3*'s is ok. But Your also boosted any thing over 3 I would want to fix.

 

Any is not good. Not that it'll hurt the engine, but the KR, even at low levels of detected knock, will pull timing for a bit to protect the engine. That can be up to 8*.

The problem with consistant KR is that the ECM's algorithms will compute a Knock Learn Factor, which essentially "averages down" towards the Low Octane Table, pulling timing throughout. That's not desirable.

Also determine if any detected knock is real or false (that can happen!). Try higher octane and if the KR is still there, likely false knock. Also, if timing is pulled and it's still there, false also. If that's detemined to be true, then consider de-sensitizing the knock sensor values some.

Best to get rid of it overall.

 

So, lets say to be on the safe side i allow 1* knock. That would be cool right so that i dont have to give up more hp.

 

yo man.. your in pitt.. can you do tunning for my ss 2.4? ill make the trip or maybe meet up at a meet or something.. id love to check out ur car too

 

great thread


helped me out alot in tuning my first 2.4
got him tuned - no knock - and running 91 - told him to go up to 94 octane see if
I can notch up the timing a bit ... for 2-3 $ a tank not a big price to pay

********* if the car shuts down while doing a flash don't panic ******************
********* some 2.4's will only respond to a write entire *********************

 

yeah my 2.4 has to write entire for every change
