it has occured to me that the vast majority of folks here utilize GUF ecus thus i felt compelled to do my part and aid in helping thy fellow enthusiast out by contributing my base A9L calibration i use on vehicles i tune, I have labelled it A9L2 to distinguish between it and a stock A9L

this 'base' tune is ideal for basically anything from stock to turbo nitrous engines
the write up can be found here

This reply was moved from a different thread:

I have a few questions for you regarding your a9l2 tune:

1. Why is ccdsw enabled
2. Why is edfhp enabled
3. Why is fn331b multipliers set to all 1.0
4. why is fn879 zeroed out
5. why is fn826a zeroed out

I am just wondering for my own educational purposes.

Much appreciated kemosabe. Should be fun to see how far off I am lol.

Just a suggestion, but one thing that might help newbs learn better is a list of the changes made with an annotation of why it was done.

I am looking forward to checking this out when I get home tonight.

most of the changes should be obvious, if you question something or want to know why post what it is

i just looked over it and i see 2 mistakes , hego bias table supposed to be all 0s and prldsw is supposed to be load=loadx, i have no idea why those are what they are but ill fix it later tonight, still at work

1. Why is ccdsw enabled
if you have a ccd tfi and ccd is disabled your dwell will be static at barely nothing, using with a non ccd tfi has no ill effects, kind of a better safe than sry
2. Why is edfhp enabled
so when you decide you want the ecu to control the fan all u gotta do is plug it in
3. Why is fn331b multipliers set to all 1.0
by nulling the accel enrichment multiplier your ae is exactly whats in the table, makes it easier to dial in
4. why is fn879 zeroed out
dashpot decay isnt 0 its .0081 with a linear decay dashpot can be finely tuned in using only pre position
5. why is fn826a zeroed out
the startup adder is done by bzztmr, that way u can clear it out sooner if need be

Got a few questions..

Is the spark narrowed down to just the sea level spark table? To start dialing in fuel,is the only I need to do is disable the fn1360?

Ps will your long tube header template still work with this bin having the load scaling?

Thanks
Jay

yeah jay sealevel only

fn1360 is already enabled but that won't dial in fuel, you dial in fuel by either injector slopes or maf transfer

you dont need the header template with this calibration, nor any of the other templates other than maf and injectors, thats the beauty of it

Thanks Mike.

I was under the assumption that turning on the fan hardware isnt enough. There is some wiring involved as well to make it functional.

I was afraid or concerned with the dashpot decay rate that she would idle hang for too long before coming down.

you do have to wire it up for the output to function

dashpot can be fine tuned in pre position i usually do something like
xxmaxxx .8
5000 .6
100 .15
0 .15
0 .15
0 .15
etc...

then you only have the .6 and .15 to adjust to get it perfect

Thanks decipha

So no changes needed between long & short tube headers and fn1360 is not patched to this bin correct?

no changes, fn1360 stabilized fuel table is patched in the bin with practical values, and fully operational

np, i do what i can to help out

dont hesitate to post back with any concerns

why is Z_DFSW disabled but you still make changes to dfso values? are they just the changes you would make if you were to run it when enabled?

yeah that way its as simple as enabling the scalar if you want to enable it, she'll function correctly

_________________

This one topic of interest I always brought up to Chris. It is my belief that dfsw was always disabled by default in the a9l calibration. I believe Chris is the one that is kind enough to keep all the gufx strategies and calibrations up to date and refined and I "think" as time evolved from 2009 or so that the pid became enabled by default. I believe dfsw was disabled by default in the original Ford calibration in the a9l and a3m series but was enabled by default in the x3z calibration. So in my oppinion Mike is correct in leaving it disabled by default in the a9l calibration. The only thing I would have Mike add is fn374 multiplier values should all be set to zero if enabling z_dfso or dfso as we know it per the comments on fn374.

I think the "enable/disable" scalar always had it enabled in the A9L BIN. I certainly didn't change that scalar and then upload my altered versions of that BIN. Although just because DFSO is enabled doesn't mean it actually worked. Other scalar settings were actually preventing it from working even though the feature was technically "enabled". So explicitly disabling it doesn't mean much since it never was really active to start with.

As for whether to use DFSO or not is a completely different discussion...one that's been discussed before and it's 100% personal preference. There's not strong argument to or not to use it. I use it, but others prefer to keep the fuel pumping to avoid excessive engine-braking.

Subscribing.

I have started with decipha's base tune A9L2, plugged in my MAF table today and was able to get a good data log and some decent idle/run time. Running @ 8.9 AFR and then runs 16 to 22 AFR on decel. Needs some personal tweaking, but it is a decent start.

damn jon, your maf must be wayyy off

the only time i really use decel fuel shut off is on turbo engines with screwed up bov's or maf placement, or if someone wants it

the biggest problem with dfso is with automatics, if you bust through the traps and as soon as you come off the throttle the back wheels lock up (had it happen) its pretty hard to prevent it from getting loose, i don't use dfso on any automatics with decent power just not safe, at least not with the minimal control the guf ecu's give you over dfso

Sorry to fixate on the fan, but are all EEC-IV CPUs wired to control fans (i.e. to they have a relay/MOSFET populated on the cct board)? I thought I'd read that it was not this way, so I wired an external thermostat switch to control my fan and was PO'd as it is a natural thing for the computer to control.

Is adding a pin to the computer connector all that's required to get an actionable computer output for fan control? If so - bugger. I'll be adding to the wiring looms then....
Thanks - I'm going to port my current tune to the decipha A9L2 and see how it behaves.

cheers-
timm

You may already know,but you will need to wire it with a relay. Hooking the ground to pin 41 can damage the computer. The computer will not support enough current to run a fan with out a relay.

Correct. I am glad you posted this as just enabling the fan hardware in the tune is not enough. Its alot more involved with the fox ecm's.

a lot more involved? such as what?

how exactly does one expect to power a fan without wiring?

_________________
http://www.efidynotuning.com/ford/

Well you elude to the fact that the a9l can control a e-fan as is. Thats not the case. The ecm needs to be pinned properly, the correct relays need to be used, a secondary temp probe for the fans need to be installed in the water neck or lower intake manifold for on off temps and a stock 80 amp alternator will not cut it with any old electric fan. A 130 amp 3g alternator is required if you dont want to melt your wires and tax your electical charging system and such. You will also need to instal and wire an a/c relay which would power the fans when the a/c is on turned on regardless of temp. That all sounds pretty involved to me if you want it done and operating correctly. Most will say the hell with the ecm controllint the fan and just power it to a key on source and a toggle switch if for anything out of shear laziness....lol...
