Idle dips

[mikeyv]

Just wondering what the cause of the rpms dipping when i'm only going a couple of miles and hour and I turn the steering wheel. Is it raf related? follower? cracker? Can anyone help me out please, thanks, Mike

I've been having this same problem since I do know when
Upped the Idle Rpms a little... didnt fix it

Power steering sag? You didn't say how much it was dipping and no other info so

[slow6]

mine dies alot
it can reach 400 rpms (or less) and stay running LOL
Its like its searching (surging) for good AFR
I've turned DFCO off
Once I get in the very low rpm range, I have to watch rpms
If it goes too low I need to let off the brake to let the momentum of the car keep it going....so it would seem

Sounds like the RAF is too low in your case slow6.
Need cal & log when it's happening & mod list to dial it in.

I having problems with rpm dipping, Ive read about RAF too low, and since I have C&H + ported maf&TB I acordingly I LOWERED the base Air flow because a hotter cam will suck LESS air (less efficient) @ iddle... stills dip, Ive raising the RAF now is close to stock numbers but I I KNOW this is not right, right!?

I have to accept that I have a lightened flywheel but not as much as a fidanza, myne passed thru a lathe!

If you have cable throttle, you may want to move the Desired IAC Steps table 3-4 clicks to the left. Copy from the first value above 0 to the end of the table then move over 3-4 spots and paste the values back in. It may or may not fix your problem but it is worth a try.

Move the Desired IAC Steps to the left? I thought if anything it would be to the right, but I may be wrong.

[EC_Tune]

Yep, it's to the left. Adds more air at the lower end.
