I recently purchased my first DSM with the issue thats present in the subject line. All my mods as accurate as I can name them are in my profile. Using an AFC NEO to tune fuel/air I have an issue building boost. Any boost. I have several questions regarding the subject. I most definitely have spent 3 days searching this issue out and if there is already a post on this, I apologize I missed it. Let me begin by stating that I thank and appreciate every and all bits of information given to me by the members of this site. Onto the issue:
I just purchased EvoScan so I can now start logging, but don't know what it is that I should be looking for. So if someone wants me to provide a log or something, I could probably do that if you tell me which options to select. Thanks again!
- Using NEO to tune, is seems + numbers need to be in large amounts in order to even begin richening out the fuel:air. The wideband I'm using takes 2-3 seconds at a constant throttle position/speed in order to accurately display the AFRs. And it ALWAYS shows super lean (---) or (17.0-18.0) initially, regardless of NEO setting, is this normal?
- Idling with no neo correction makes the car stall out so I know the neo is working somewhat, but the numbers required to idle or operate the car correctly are outrageous in my opinion. Ex. +30 at Ne1 (1000rpm) and more at each Ne point, is this normal?
- The car runs normally at low throttle and while slowly increasing RPM, WOT makes the car spit and sputter, like it can't adjust fast enough. And even low throttle but attempting to build boost (any at all) makes the car spit and sputter like crazy! In it's simplest form, it is impossible for my car to build boost.
- 1. Car was originally an automatic, and I've been told the ECU is still the automatic one.
- 2. MBC has been set both ways (all the way open, all the way closed) no change.
- 3. I've read many neo usage posts and articles so I'm pretty sure I'm utilizing it correctly. + Numbers = more fuel = richening out. - Numbers = less fuel = leaning out. Unless I'm confusing the two. But I've tried it both ways and have gotten no change anyway so that doesnt matter.
I just purchased EvoScan so I can now start logging, but don't know what it is that I should be looking for. So if someone wants me to provide a log or something, I could probably do that if you tell me which options to select. Thanks again!
