Thread: VE Tuning... wtf?

Firstly, I'm using HPT... Took me 3 or 4 days to make the sweet config file I'm using

Maf disconnected, PE disabled - All data is logging correctly and accurately, Problem is : After adjusting my VE table,
which is lean by 15%-20% at low rpm, I flash the new adjusted file then re-record...

It stays the same... Or worse, it runs even more lean! wtf is going on here?

At 2,800rpm/30kpa, I have 1.23. I multiply that cell by 1.23 and on the next dyno pull, it went to 1.27 lol



anyone?

on certain years/cars, the VE table is ignored, on others it plays a large role....I have seen this a bunch of times.

The accurate way ( and some will argue) is to set the Injector table to what ever you have and then scale the MAF to get the correct fueling out of the car. Others will tell you to set the Stock MAF, and then change the IFR to the the correct fueling. Really dosent matter....but to get the car dialed in this is what you need to do

^^^^ IFR before maf...totally agreed. It will save a lot of headache later.

BTW op if I'm over 20% I just paste special add then I paste special multiply half percent when I'm getting closer

I assume your talking about the maf curve and not the VE table?

Hmm, I thought my car used blended operation of the 2... Thanks for chiming in here, saved me a lot of time.

If that's the case in all pcm was the point of the dynamic airflow setting? I was always under the impression pcm would use blended operation until a certain user set rpm and switches to maf only
