too lean ?
@AndyF, thank you but that does not describe why it “has” to be dbw. I see it working just as well with drive by cable, simply because it would just have to wait for certain driving scenarios and conditions before parameters are set. Kind of like current ob2 diagnostics. For all of the monitors to be “up” and ready certain conditions have to be met. My AEM infinity is the closest I’ve seen to real self tuning. It uses o2 feedback to trim the fuel table and suggest a “new ve”. Although you do have to target certain afrs in different areas of the map.
Thanks for all the replies, a lot of answers are over my head some what tho .
The fast 2.0 is a supposedly self tune set up , but its to get the engine started (fairly rich) and self tunes from there , but has to be leaned down more , from my exp.
I did go from ngk 7`s to ngk 6`s , ( Andy`s suggestion) , which made a big improvement in plug color , and have even thot about 5`s . Have leaned it further , a couple of clicks a couple of times , I have experimented w/ timing a little and have the initial at 21 right now , ran 20 for most of the time , it did seem last summer it was hard to restart w/ the timing at 21. All in is 34 at 2800 right now , have been running 35 all in at 3000 before for the most part , on 93 oct , non cat piss.
I haven't pulled all the plugs just the easy few, most of the time , and haven`t recently . No 7 is directly in line w/ my steering column , and have a hard time getting it back in straight , ''raised port heads.''
Rechecking the plugs is probly my next step , they have looked like their still rich so far . I have been busy w/ other stuff , and don't get to mess w/ it much in cold weather , "did I say , I hate cold weather ?!" . Turning cold again and supposed to snow , cant get up for it when cold -------------
These raised port heads would b kick *** in a B body, but kinda suck in a 68 fastback , would have been trickflows if they would have been out when I was in the market ---------thanks again guys .
