Drag and Drive Baja

Top is AFR in real time. Main is vacuum/boost.

Wish I could get a full pull in video.

Oh! I better go watch it again!

The second pull video I swapped it to boost only. That innovate gauge is pretty awesome. It records max boost and also can act as a boost cut device.

Mine is way worse than that at idle I think.

You should be able to kill the oscillation by setting ask these timing and fuel settings your idle cells to the same values. So toy might have a block of 6 to 9 cells with a VE of 45 and 6 to 9 cells with a timing of 10 (as examples). That should cure the hunting.

Mine used to hunt super bad. I ended up doing like Mario said and I set I think 6 cells around idle in the fuel table to the same amount and then I added more fuel. Seemed like for me, the more fuel I added, the more stable it got.
I already had the timing table pretty much blocked out maybe 5 or 6 values on the entire table. I did end up doing a smooth on it so it wasn't having to hop from one value to the next. My idle still isn't great though.
I'm on E85 though.

So adding fuel flattened out my idle. Need to fine tune though as now my hot start is a bit off. Closer though.

Also think my clutch is starting to slip while loaded in third.

Nice. That seemed to help me too. Afr's are richer but I don't really care about that. My hot starts suck too. But again, on E85 starts are never great from what ive heard.

So took a friend for a ride and determined that the clutch is slipping! With a passenger it slipped so bad I couldn’t clear 8 psi loaded in 4th.

It holds at 6psi so I’m gonna try and finish up this year with the clutch and figure it out maybe at the beginning of the year.

Oh man I couldn't do it after tasting 20 psi!

[Schweg]

It’s not that hard though I say that and I’m not thrilled typing it.

I get it though. It's hard to want to tear it down. I put in a stage 2 Kennedy and metal woven disk and it seems to be holding well so far.

[Schweg]

I’m thinking stage 2 with a copperhead disk.

That should do it.

[Chip Birks]

That should do it.

Keep it below 250 at the wheels and it should be okay, any more that that and the clutch will not hold for long.
