Correct its the newest strategy for the them.

I wont be releasing an READ0 def til a premoum member needs it. Thats how all my defs come to be. I make them when someone needs them and then post them freely to use.

The strategy doesnt matter on any ecu just the hardware code. Thats what the search box is for on the downloads page on the homepage. Many eec-v's are the same class and can be swapped.

They list as 216k cuz thats actually what it is rom wise, 224k includes ram and 256k contains all the filler for actual flat addressing. Its actually russian software.

They have to copyright the cal file a year before production so you will always see stock tunes being the year prior. Updates will come later like the 97 crown vic with the dealer flash update got a 2006 cal file.

Yeah it will run as you can damn near run anything on anything pretty much but its not ideal.

Other than the cam type, the different size injectors and that the OHV deletes 2nd gear they are pretty similar tunes. The SOHC will be neutered from the low timing running the OHV cal and fuel will be off probably 20% or more at idle. Interestingly enough they actually fuel very very closely up top.

This is comparing a SRE1 (SOHC) and LLA1 (OHV).

you set your high speed fan and low speed fan temps to the same ??

you should never use a global spark adder unless your doing diagnostics, go ahead and set that back to 0.
FN2200 is the borderline knock table you can go add some timing in there if you wish.

FN2300A is the mbt spark table. You can use it as a reference to add some spark to fn2200.
You can see there's quite a bit that can be picked up down low but not much of anything up top.

But yeah you did an excellent job. Apparently you read as most people don't set the scaling percentage to 1 so all their values are jacked up when reading out a stock tune and going from there.

no need to throw it away just have it as an option to not label args at the top of the directive

Shouldn't matter but can't hurt.

reac4 is unchanged I hadn't done anything with it in years.

you cant swap cals and strats. You have to use the cal for the strat. Simply use an READ0 cal if you want to use an READ0 strategy or use the REAC4 strat if you want to use an REAC4 cal.

pprv is a regulator, functions 100% identical

nope, pump prime time is good stuff thats why i created it

if you have a regulator then you have a pprv either will do the same job no prob

added more notes and preferred cals

On the intake stroke the cylinders are under vacuum that's where your engine vacuum is created.

The stock intake valve is 1.46" diameter which gives you a surface area of (1.46/2*3.14==2.29 square inches)

18 lbs per sq in of boost == 18*2.29== 41 lbs of spring pressure lost due to boost. It may not be an issue if you have sufficient spring pressure already but if your on the edge then it could cause a valve to float.

Here's a couple articles if you want to check them out.

Nothing comes next, it calls out does the error calc and returns for the look up.

DSDRPM is unsigned as its the commanded idle rpm.
I figured out my problem, I was having a brain fart from having one of my lookups labelled wrong in my directive.

If N_RPM is a lower value than DSDRPM something was preventing r34 from rolling back.

ex: r34== 500 - 800
== -300

It helps when you use the correct lookup.

All good thanks.
