Re: [GUFX] Strategy Files
Updated a9l2 and gufx posted. FN111 revamped, all dashpot is now rpm error based and corrected some lookup malfunctions on fn338, fn320 and the like.

Re: 400hp 351w startup tune
pull 15 degrees out right there and it should make significantly more power

Re: 400hp 351w startup tune
that looks horrible
41 degrees at wot between 1250 and 1750 rpm is significantly over advanced
the mbt guidance on the homepage would get you much more in the ballpark

Re: Are newer Ford MAF's all 5v Reference
read the maf write up
its ground reference -5v not positive
the ecu is expecting a period freuquency input not voltage as the maf electronics does the conversion

Re: Clearing a Flooded Engine w/ the MAF Table?
You can actally put the maf in upside down and it will still work
seen someone do that once
not recommended but appeared to work fine

those look like the valve covers off the 351w trucks.

Re: Clearing a Flooded Engine w/ the MAF Table?
I have no idea what your trying to describe about the maf but the ecu uses the top point for lookup and works down. Its the same for eec 5 as it is eec 4.
1023 23
0 20 <--- zero ends the maf curve
below no longer exists and is no longer part of the maf curve regardless of what you put in there.
900 1600
850 1400
800 ....
the above is a valid and non corrupt maf transfer.
You cant have any lower x axis value higher than the above value or it will corrupt. But 0 ends the maf transfer.
ex:
1023 23
1 20
900 1600 << will corrupt the maf.
remember all x axis need to be maximum to minimum values in chronological order for all functions otherwise youll corrupt it.
No, the reason why your maf is inverted is because you didnt setup tunerpro correctly per the getting started write up.

Re: Clearing a Flooded Engine w/ the MAF Table?
no need
simply hold the pedal to the floor while cranking and it shuts off the injectors
and btw you dont have to change all the maf points just the second from the top
change 900 in your example to 0. then set the flows for that and the one above stupid low like you want.
example
1023 30
0 20
850 xxxxx unchanged and unused
btw you show your values inverted.
Also my crank pw code in gufx shuts the injectors off during excessive cranking regardless.

Re: CMP sensor type and offset/info
cam sensor is same as crank its just a simple a/c sine wave variable reluctance sensor for all fords 99+
if its an 01/02 ford engine in a mazda then usually its the same ecu as the ford and runs all the same cals. The mazda pickups come to mind as they run the same ranger ecu's.
