I have followed Gameover's guide to setting your idle but I'm still getting pulsating idle when it is in open loop(I assume that is what it is caled when the engine is warming up). I don't know what to adjust to help with the pulsating. The engine sounds like vroom,one,vroom,two. I have a 224,228 cam and was looking to smooth this out. Once it gets warm and the closed loop kicks in, it stops pulsating. Any sugestions would be helpful? Thanks.

If I lowered my Min ECT temp for Adaptive Idle Rpm to engage the closed loop could this help?

How do I get to Gameover's guide?

Sounds like an airflow issue. Maybe you need to bump your airflow up a bit between those temps?

What programmer are you using...HP Tuners has a bug in one of the released that sets a min. speed parameter incorrectly and caused the same situation upon startup...

If you are using HP Tuners, let me know and I will look up what the actual parameter was and let you know...

I chased this for 2 weeks before finding it on their website...

multiply first column of VE table by .96 then 2nd column by .97 then 3rd by .98...

try that

I am using Hptuners 1.6 and I am going to try the VE cut back first then if that doesn'e work I will try the OLFA method to see if that is what it is.

I tried the cut back method and it made the engine sound like it was starving it and made the pulsing worse. Now when I say pusling I mean 4 pulses a second. It is not a rev thing. So I tried increasing the three colums by the inverse proportion(first by 1.04,second by 1.03,and third by 1.02) and it seamed to help a little bit but still does it ocationally. So I am thinking of increasing it a little more but what is the risk if I go too high?
