Thread: Lynch's 6spd / VE-T thread

Ohi know how its suppoae to be done but finding a place to do it an not get in trouble is not so easy.

Try to keep cruising afrs in the 14-15 range,any leaner you start burning oil and heating it up for hardly any gains in mpg.

Ya I've been working on the cruise portion of the tune today.. this mani with fresh plugs with smaller gap has made it require more fuel everywhere

how old is your O2 sensor?

check the plugs after you drive it for a while.

My wideband is a few years old.. I didnt use it very much the first few years tho.. and I dont run a narrow band.

I've had my friend. In the car with me and I tell him what to change and I've got the 50 to 60 mph range sorted out pretty good but the lower mph still meeds work.. kinda weird how in 3rd in the same cells the afr will be a lot different then 4th or 5th..

I plan on checkin tbe plugs again now that I have the cruise in the high 14 low 15s.. I havent rewlly givin it much boost if any today so we'll see what they look like.

you may want to find a dyno to verify how accurate your sensor is, mine only lasted about 2 years before I had to stop using it (although that was b/c of the short time I was running extremely rich) When i got it on the dyno, i found out it wasnt reading correctly some of the time.

also to get an accurate idea of the tune based on the look of the plugs; you are supposed to start with fresh plugs and shut off the car during a run and immediately check them.

Agreed, on my Roller Rocker I actually lost MPG even running 15.5. It seems to like ~14.7-15. Also roller rocker hates timing!

Ya I can tell mine likes 14.7 to 15 also.. juat the way it feels... im also tryin to get it to be not so rich when I dip into the throttle..
