The only time I weighed it was about 2690, but I've fattened it up a bit.

I was not going balls to the wall, but 12.35 is pretty quick for a stock longblock G.

Car did trap a 114 the first run of the day, with a 14.9 ET

Ugh. Don't get me thinking about E85 again! My pursuit for E85 is the reason i'm replacing my motor now

And you're in the same state as me? Ugh!

It's on pump now, for DD purposes. I would average 20-22mpg on the corn, but now I hit 27.27mpg on 92e10. that 5mpg adds up! That and I don't flog it at all anymore, so it's a waste of fuel and money to keep using it.

1st. I thought E85 makes up for worse MPG by a lower price?

2nd. You seemed to be getting so much extra power from the fuel conversion, I didn't expect you to revert. Remember your post that 12psi on corn beats 18psi on gas? With even better spool.

I'm very interested in your reasons for switching back to ordinary gas.

The cost difference is half a USD per gallon. It is also only E70 until late June.
My only other gripes were cranking fueling, and cruising afrs. Because I changed mafs, used injector scaling instead of just modifying fuel cells, it seemed like cruising stuff had an issue with finding the proper load values.

I also only drive the car 2 days each week, and that happens to be at each weekend. So the fuel sits and collects moisture for 5 days at a crack. It was getting to the point with our weather that you could notice the fuel becoming diluted with water.

I'm also becoming a little more responsible with the car, I don't feel that making the power to trap 114mph in the quarter mile (~320whp by the standards discussed in the PPB section) is a smart idea on this 20 year old engine with stock components and composite gaskets.

I should have noted that this is only a very temporary "switch", by the way. I will ultimately be going back to the fuel when the time (K heads, reverse G manifold, 207 shortblock, small efficient intercooler, evo3 compressor wheel) permits.

As you can see, it was getting out of hand

Unbelievable!
That is insane timing. I can only imagine what the car feels like. I see you've still got the low load timing for the pops and bangs. How are those working out? In my case, it simply means that exhaust gaskets have a 2 month service life.

It's nuts, because with the fueling mixed with the low timing and the throttle kicked ever so slightly, the boost gauge goes from -25hgmm to like 3psi every BANG. On gasoline, it is just a noise maker.

I wish we could set timing to a negative value, and then add oh, 30% more fuel at those values

Let me in on your rotating idle code!

The timing is actually negative. I wrote a function that modifies what I have understood to be 'time till next spark event'. You can adjust that parameter to make the timing more negative, I didn't have the courage.

Rotational idle is still in development. Hopefully in 2 weeks it will be done, laziness permitting.

It tastes like burning

Am I the only one who doesn't want to blow their motor anymore?

Hey Paul I have an idea for negative ignition timing that might be easier (and SAFER) than modifying the current crank position or next event timer. I will send via email.

Let's get some real antilag going!

I'll be test bitch

I've tested 5,10,20 for the timing values. From my prev experience with DSM als, the loudest and best results occur at ~30, a kicked plate, and ~20% fuel

Romraider only edits the rom. You need to purchase chips and a chip burner and use other software to burn the rom to the chip. You also need to download and install the EJ20G definitions to romraider.

I've decided to stick it out with the ej20g ecu, unless I could make esl use rotating idle. I don't think they ever will do a als/ri. I think lc and ffs is on the way.

I did switch off it while my car was my dd though, for mpg purposes.
