Thanks for the advice. No, I don't do my own chips, I just don't have the time for the learning curve and the testing and retuning and such. Wish I did. I have had Azzato and Pcmforless do chips for me. For both setups the Azzato chips have been much better. Have had to make some tweaks and am glad I have an AFR gauge but Azzato has done the best so far. I'm trying to decide if I should have him try more AE to clear up the problem or to just run without IAC. I do still have the high idle at warm-up even without IAC, which I didn't think I'd have. The only time I see the IAC helping at this point is to smooth out the idle a little more, and when I turn the A/C on, which isn't often since it is a vert. When I give it a little more gas and it clears up, it is not entering PE mode. Don't have to give it that much more gas for the clear up to happen. That makes me unsure of it needing more AE. You could be right tho. I really thought it was a specific block learn cell too lean but the block learn that it is in when the problem occurs is also used other times, which makes it whacky. It obviously gives it as much fuel as possible during the lean condition, which still isn't enough, then the next time that block learn cell is used it is way too rich and needs to correct back the other way. Again, can all be seen on the AFR gauge and with Tunerpro datalogs. One other thing I think I'm gonna try is to have the target AFR set at 15.5 instead of 14.7 at all part throttle driving. Seems that there is no cam surge when the AFR is in the 15.5 range. Anyone else doing this? Should I also try 15.5 target at idle since I am very near idle conditions when I'm at very light throttle highway cruising? |
