Need some help again! Got a question regarding overall timing please see log inside

Ah10@WMS · 10-10-2006, 09:14 AM

Did another log this morning but i have a few questions on overall timing.

Ambient temp:66F
Fuel: 100oct(1/2 a tank)
File: X file
Humidity:67%
Altitude: 430ft
Boost: just a hair under 22psi spike, taper to 20psi by redline

Here we go:

Here is my specific question, why is the overall timing bounce? it was on its way climbing up and what a sudden it drops and climb back up? cf were too good(in a way i dont like it that much, would like to see some CF) and knock wasnt bad and it didnt have too many sudden spike?

Sorry, forgot to hit the start button on the WB but i didnt touch fueling for a long time afr should stay the same as last log, low to mid 11's in midrange and 11.5:1 right before i let off.

Anyone knows (Mr. M&M, Nyet, Midget, Flyboy, Dap, SmokingS4, Dvs2.7T and ............)why is overall timing bounces? when i run pump gas i didnt see such activities only when i am on Race gas.
I remember Midget and SLPRS4 have the same Experience before!

Thanks

when it sees high mid range timing due to race gas adaptation.

Mine is much more pronounced than yours because I pulled the ECU and added timing to get the midrange timing higher:

I would like to see just a little bit like 0~3d of cf(learn that from the Moss man).

would like to add timing as soon as i can figure out why overall timing bounces.

does it make sense to joo?

Patrick had similar CFs to me, but choppy timing like the post I made above....best of both worlds :P

My only explanation could be that X just flat out freaks when it sees real solid mid/low range timing because it's not used to it.

When I didn't add timing via Lemmi and ran the same X settings with race gas, these were the results:

Lower mid/low range timing, but no crazy pullback which I guess resulted in good performance due to more timing under the curve?

which further proves IAT has a direct relation to overalltiming angle. you are starting at 100F and staying around there. I see nothing in the raw data to explain why other then high IATS to start off with.

As for X, seems that it freaks out a bit... when it sees high mid range timing due to race gas adaptation. Mine is much more pronounced than yours because I pulled the ECU and added timing to get the midrange timing higher:

PSmalls::AnalRetentiveNumbNut Member Garage is empty, add now Join Date: Aug 2006 Posts: 2,688	I talked to Moss about the overall timing bounce, suggested I go to tweaker file with X and XR. My only explanation could be that X just flat out freaks when it sees real solid mid/low range timing because it's not used to it. When I didn't add timing via Lemmi and ran the same X settings with race gas, these were the results: Lower mid/low range timing, but no crazy pullback which I guess resulted in good performance due to more timing under the curve?
