ECMlink Ideal Timing Numbers??

[skatershawn]

Hello all,

I'll start by answering the question above.

1)I have no boost leaks that I can find; she holds pressure well.
2)Done.
3)Done.
4)Stock coil, AEM Wideband roughly 4 years old, NGK 7e's gapped at 0.28.
5)Last checked she was roughly 164 across the board on warm engine cranking 4 turns.
6)All good.
7)0.020 over but stock ratio.
8)One that I noticed; the Coolant temp sensor wires.
9)One recently; injector circuit malfunction.
10)good and good.
11)~43, +/- 1psi, 550cc's. (plans to put 850s).
12)AEM, Id have to check when i get home.
13) 93oct, up to 10%. (thinking about running e85 with the 850s)
14) Indeed I have.

Ok now I'll ask. I posted this on ECMLink but have yet to get any replies so I figured I'd ask the crowd I know I can trust!

I was curious as to where my timing numbers should be. I'm seeing them at around 35* at cruising and they range from 20-14* at part to full throttle, then I see them spike to 40+* the moment I let of the gas, then they settle back down to 30ish.

I am having a little knock at WOT which I believe was due to me running 550's on a 14b set at 18psi but spikes to 22+psi due to a faulty MBC.

I just purchased some 850's that I plan to swap in with my big 16g and tune for e85 on 22psi.

Any one have any insight on what good timing ranges should be?

Thank you,


Shawn

Every setup is different so will be the timing. There's lots of things that will affect the timing , cr ,fuel being used, intake temperature & so on. I would say start with 2g or evo . As for the timing fluctuate this is normal.

The timing numbers you posted don't look abnormal. I think you probably fine. Which timing map are you running, stock 1g, 2g, evo 8 or modified?

Timing map should be stock 1g. I haven't messed around with my timing. Just some of the fuel while I tuning for the 550s when I swapped them in.
But last night I finished up my clutch job and master clutch cylinder, while putting everything back together I noticed my throttle cable had a bit of slack in it. So I adjusted it and tightened it up all nice. This morning when I went for a cruise the car wasn't acting up when I let off the gas.
Before, when I let off the gas the idle would drop and the car would act as if it was about to stall. I looked at a few logs and noticed the timing would drop and I thought it might have been the reason that is why I came on here to see what the values should look like.
She isn't doing it anymore so I assume it had to be something with the throttle or maybe even the bad pressure plate.
Not sure but it isn't doing it anymore.

But it's still nice to know you all say those are proper looking numbers.
Car is still pulling some timing at part and WOT. But I know that's from spiking to 22+ on 550s and SMIC.
I'll soon be dropping in the 850s so i'm sure ill be back to ask some question about tuning those; or possible tuning for both e85 and 93oct.


Thank you all,
