And so far Ive gotten a good bit of it done. My only problem is when i first start it, it hunts for idle and dips down to 500 rpms or so. I know there are a few threads on this, but I cant find them If the ve table is tune properly and the maf is just -2 to 2% off, shouldnt my acceleration be about the same? there are points that the car bogs a bit when i give it more/rapid throttle. A little help please fellas

Did you get VE dialed in near 100%?
If so adjust your maf table based on AFR % error from commanded AFR.
Ie if it runs 10% lean over the whole table, scale your maf table up 10%

You might need to take a look at tuning idle by logging running airflow and desired airflow . Do a search for tuning RAF on hpt or efi depending on what you have.

 

VE was almost spot on. not too far off at all. im using a histogram for maf afr error%. I did the RAF tuning in OLSD. Do I also need to do it again with the maf plugged in?
