Mine starts at 385 and goes fairly linearlly down to 100 at 235*f

Godless Commie 05-22-2012 09:30 PM

Wouldn't that mean a whole lot more fuel?

I have 650s, btw.

Braineack 05-22-2012 10:07 PM

So? Its in % of.

Unfortunately, that's not entirely true. Good luck starting with 650cc EV14s and 100 at the highest temp

Braineack 05-23-2012 07:55 AM

well he aint having any luck now :)

Cranking twice to start it from completely cold means that may have to add/remove 10-15% fuel, not 300-400%.

Braineack 05-23-2012 08:56 AM

This is america, go big or go home!

Even at $4 per gallon?

Braineack 05-23-2012 09:07 AM

especially then! You gotta spend money frivilously like Greece in order to make yourself a super power.

Reverant 05-23-2012 09:09 AM

By being forced to buy US, German and French planes, submarines and boats by using money we are given as stimulus, right?

Hello.. It's over TEN BUCKS a gallon over here..

Also, Dimitris, there is a "cranking episode" in the log I sent you, as well.
(At the very beginning.)

Reverant 05-23-2012 10:08 AM

In that log, the engine starts (RPM > 900) in 0.8 seconds.

Godless Commie 05-24-2012 07:12 PM

OK, I bumped the cranking PW by about %15-20 across the board, and it made a visible difference.

I will add another %10 and try it one more time. (Now that the engine is cold again)

Oh, I never see the MIL coming on. Isn't it supposed to?

Godless Commie 05-24-2012 07:56 PM

Very cool progress!

Increasing fuel by another %10 made it better.

And, increasing cranking advance from 6 to 12 degrees made it perfect!

Here is the final version of my cranking table:
(with 12 degrees of cranking advance)

Reverant 05-25-2012 01:05 AM

You don't want that much advance during cranking as you may kick back the starter.

Godless Commie 05-25-2012 06:34 AM

Hmm. The car seems to love it, tho.
I'll try it a couple more times before I bump it down.

Reverant 05-25-2012 06:38 AM

If you don't have a problem with starting, then leave it as is. However, my experience with 10* of cranking advance is that it randomly kicks the starter back. It depends on your actual cranking speed etc. For example it happens a lot more if your battery is not 100% up to the job.

Godless Commie 05-25-2012 07:24 AM

I understand completely.
I have quite a bit of hands on experience on engines, especially ignition and engine management systems, and bumping the advance has always proved a better starting scheme for me.
What I don't understand is the negative prop I have received for reporting that increased pw indeed helped starting the engine, a couple posts ago...

What negative prop?

Btw, do you actually have a check engine light on your gauge cluster?
