Filtering Data

[Black02SS]

I altered my Base Spark Table in Gear to reflect 39* at those cells and I will be trying it as soon as the wife goes to work... (She doesn't know this yet... shhh)... I see totally where you are coming from now on this. I have two more pics for you guys to see the differences.

Bink - If the timing in the bast spark table in gear doesn't help the issue, how would/do you suggest to tune the low MAP values? I would think just to use the values for 30kPa and below and leave the 35kPa above without FTC 21. Make sense?

I try to hit as many lower MAP cells, as possible, using long sweeping hills and steep hills. Steep hill and minimal TPS (lower gear) seems to work well for low MAP/kPa. I would then use decel data for those I can't hit otherwise - and blend it. My .02.

Cheers,

Thanks joel, its flat here. :lol:

Oh, sorry.
Head towards the hills......I'm in Cincinnati. We have a bunch of them.
Long and steep. Going down -low kPas. Going up - high kPas.

My car idles at 1125-1175 rpm and 70-75 kPa - I can't really hit the very low kPa and low rpm cells.

same here, but the ship channel overpasses are great!

I'm almost afraid to ask - but, how much overlap do you have at 0.05?

Would it not be easier to apply a filter to exclude less than ideal timing?

That sounds like an adrenaline rush.

239, 251 on a 106 lsa. 0.570" lift. Installed straight up (not that it effects overlap). 33* overlap at .050".

They call it the "Grand Am cam".... I think of it as "The Old Man cam".


Funny thing is when I put this cam in the "gurus" told me it couldn't be tuned AND it would not make decent HP (they new better than the Great Grand Poobah aka GM). 2-3 years ago conventional internet wisdom, in the States, was - "LS1s don't like a lot of duration..like the SBC does".

Thanks to NoGo, GMPX gojo/jfPilla, and all the guys on these boards, it does pretty well.

I think I just wet my pants. - - Yeah, I did...

How's low speed driving <30 mph, school zones, parking lots, etc?

I bet that thing pulls like a mad arse up top.

It's not a big cam nowdays. Many are running 240-250s at .050" with 0.600s lift - BIG stuff.

It does very well at lower rpm thanks to my Nick Williams 90mm TB (Sounds like a commercial :lol: ). Low rpm throttle response vastly improved with the TB. I have 4.10s and an M12 (2.97 1st?) which really helps keep it in the 3000, and above, RPM range. I can cruise in 4th, 5th and 6th down to 1500 RPM - it's amazing what can be done with compuerized EFI.

Above 4000 rpm the cam wakes up - you can feel it kick in. Good fun.

For your original problem you can filter "including all data" where FTC not equal to 21. THis will include 20 and 22 if i am understanding your questinon correctly after a few beers

Thanks man.
But , I don't want 20 either. Just 22. I double filtered as Paul suggested. Been way too hot around here to do much in the way of scanning/tuning - 99*F this afternoon.
