SD Jitter fix.

[grntsiturbo]

There are now 3 beta jitter fixes for the SD patches. I have the xmls for 2 of them. the second two of them.

Has been tested but not by me. 9653

<table name="Scaling Factor for Transition Load" category="Speed Density Programming" address="1230" type="1D" level="1" scaling="uint16"/>

<table name="BT -> NOP for Static DeltaMasterLoadPos/Neg Threshold" category="Speed Density Programming" address="27a0a" type="1D" level="1" scaling="Hex16"/>


for the first listed change 112 to 0.
for the second change 8909 to 9. You must enter it as 0x0009 since its a hex.

Im posting this since MR Fred hasnt seemed to make the transition yet.

I posted it here so HE gets the credit he deserves. Im about to go try the later fix a shot now.

Hopes this helps

ALSO do just one fix not both as recommended by MR Fred

just tried this with my buddy derek(diiirk) on 8859 on my car and its a vast improvement! just a slight jitter around 2k but barely noticeable.

Hey guys,,,

I'm testing a v7 8859 rom now and can't seem to get my hands on the sd literature for the rom... Mrfred's host site is down currently and I don't have it downloaded already.

Can anyone post or pm me the zip file or xml that needs to be copy/pasted to the 8859 rom??

Thanks a ton!!

I take it this is a fix for the IPW jitter when transitioning from closed loop to open loop correct?

yep thats what it is. I have not been able to drive my car for over 3 weeks since its been bad weather. Ive tried the third fix with success others say the 2nd is better. Ive had no reason to try the 2nd since the problem was eliminated for me with the 3rd fix.
