Nice!

[93gtpeater]

It will be my first time at the track so anything can happen.

[Murlo26]

It will be my first time as well. I will be more than happy with mid 11's first time out by the end of the day.

Guess we will see.

Partial log from my 30 min cruise into work today, checking cruising trims...

The Cruise trim looks good, or what I assume is the cruise, looks like trying to add fuels at idle though, or what I am guessing is idle. I never know for sure as I log LTFT_Used for Jon.

Next up more idle logging, partial boost and maybe some WOT!



At least trims aren't maxed out, so they aren't too terrible...needs work to get back right though.

Glad you didn't spring a shifting problem suddenly! Looks good now tune it up and go have some fun!

I am already having fun

Did more logs today! Car is running great.

Did a partial WOT run, mostly watching AFR's...looked good!



Time to turn the wick up, see what one wally 400 can do.

Oh, biggest thing! I went up to 15psi or so at near empty (maybe an 1/8th of a tank), I had fuel! yay...new fuel system so far so good.

[Murlo26]

Few full logs...



Upping boost now.

[scheides]

Sweet! Hope it will do 600+!

hot diggity

[Murlo26]

Da fuck?

Apparently my car felt like starting to spool sooner...3800rpms?



Jon, what are you doing to me?

[Murlo26]

So Jon said there was an alt map with more boost...tried it out! Surged badly when i went WOT at 2.5k, so rolled into and this happened.

[93gtpeater]

Dam you rev that bitch out. Looks like you need to do some fine tuning. so 10s this saturday?

[Murlo26]

I'll be happy with 11s! It's my first time.

[scheides]

Starting to look like my ef4 vdrs maybe its the cooler ambient temps helping with spool-up?

[93gtpeater]

Hope you make it saturday.

[Murlo26]

So today starting logging the new MAP, which slowed spool down because it was surging. So backed MIVEC down.

Here is what happened with boost when it surged.



Keep in mind, warmer now then when I took the last logs by about 30degrees.



Then, second run, found some issues it looks like.



I did these runs about 2 mins apart, so we are thinking I simply emptied the basket where the fuel pump sits. So looking like I might need a surge tank anyway

At around 7500 or so I stop watching fueling and start watching rpms for letting off for shifting etc and watch knock. The car didn't knock at all above like 6k, just small stuff lower down which I think is motor noise.

The new fuel setup has plenty of fuel pump I think its just at lower tank levels the basket drys up now. I was at 1/4 of a tank.

So I guess over the winter its time to research surge tanks.

Stop fucking around and fuel cell the bitch.

x2.

Or just don't rip it when out of gas. That would be the least expensive solution. Is there any way you can have the tune flagged for this condition and let it not let it destroy itself? I mean yeah a surge tank ...fuel cell ... thing a mabob.. etc.. Would take care of this but eventually a car runs out of gas. It does happen.

This.
