Lean at wot

[TireFryer]

I really am about to just put it away and leave it alone for a few months because I don't want to blow up my engine.

 

[Mr.Spool]

I will go get a new o2 sensor tomorrow when the parts store opens.

if the chip is cut for alky then you need to run the alky especially if your running higher timing and boost.

 

[TireFryer]

ill leave the system on at all times from this point going forward

 

[Mr.Spool]

He's only opend the throttle to 1.5 volts,but has reached 6 psi boost The wideband richens from 16 to14 when it should be 11.5 -12.0. The narrow band mimics the wideband. It just doesn't move as much.

ok,is the alky spraying at that point?

if the wideband is showing movement and fp rises 1to1,and you have replaced the maf sensor and that did move things in the right direction,,i would replace the narrowband to see if that helps as suggested above.if the sensors are working i would richen the car up in that area or send the chip back to eric and send him the file and see if he can richen it up for you.

 

[Mr.Spool]

I'm 16 and i just put this engine together so i'm learning as i go.

take your time with it,its not always just one thing could be a few.the guys in the thread have suggested some good stuff just be carefull and dont go putting your foot to the floor

It turns out he lives about 40 minutes west of me hear in Michigan so I'm going to see if we can hook up tomorrow.

Even better

 

[TireFryer]

Got it figured out! I had two bad MAF’s!!!!!

 

[TireFryer]

Thanks to ttype6 for coming out with a spare! I got into about 8 psi and it went right to 10.8!!!!!

good job!

 

[Ttype6]

good job!

I'm an excellent driver.

 

[TireFryer]

Here is a log directly after changing the maf. I pulled a lot of timing (6 degrees) out of 3rd and 4th because I wasn't running the alky yet. Looks like the blm's are high at wot so I will add wot fueling to get it as close to 128 as I can.

Hello all! Went for a nice evening drive and took some logs. Here was me just rolling into it in third gear.

Did you richen up WOT fuel? I see the blm is still 140. Is your air/fuel target still 10.8? I like the wideband numbers.

 

[TireFryer]

i made the base wot 140... seems it didn't work? air/fuel is stilll 10.8 but i never really romped on it
