Want to load up someones else's tune.. Ive had it with mine.

[waterbug1999]

Ive had it with my tune... The few peeps that I have talked with say its screwed up because the original shop tuned with with the IFR thus leading to all other kinds of band-aid fixes...

So, does someone have a tune that might work with my combo?

36lb injectors.
G5X3 cam
Dart 205 heads
90mm TB
90mm FAST intake and all the other bolt ons.

Is this even possible? Let me know, thanks.

Basically, follow these steps:
1. recalculate your IFR: http://www.marcintology.com/tuning/injectors.xls
2. do the AutoVE procedure using wideband,
3. do the idle tuning procedure: showthread.php?t=4661 (http://forum.efilive.com/showthread.php?t=4661)
4. stay in OLSD.

Also see this "What to tune first": showthread.php?t=7867 (http://forum.efilive.com/showthread.php?t=7867)

The thing your tuner can't do is spend lots of time dialing in your combination...

On the other hand, you have much more time, and you can dial in to your liking.

You injector tables need to be right, even the offsets.
If tuning on the street I suggest doing it in CLSD for {B0101},
This will give you a smoother VE table.
Keep PE on and filter out
SAE.TP.% changing more than 5% 100ms OR
GM.AFR.:1 is less than 14.62 or what {B3601} is
and with this calc.pid (LTFTBEN):


#Units Low High Fmt Expression
#------------ ------ ------ ---- ----------------------------------------
*CLC-00-010
factor 0.0 1.4 0.2 "({SAE.LONGFT1}+{SAE.LONGFT2})/2/100+1"

#Code PRN SLOT Units System Description
#---------------- ---- ------------ --------- ---------- -------------
CALC.LTFTBEN F010 CLC-00-010 factor O2-Wide "LTFT BEN"

Paste LTFTBEN to {B0101}

Then with the same log filter out
SAE.TP.% changing more than 5% 100ms OR
GM.AFR.:1 is greater than 14.62 or just under {B3601} OR
CALC.LTFTBEN is not equal to 1.00
Paste BEN to {B0101}


The enable the MAF in open loop (OLMAF), use the standard BEN filter
and paste BEN to {B5001}
Once BEN's are straight enable closed loop (CLMAF).

Use the LTFTBEN filter and standard BEN filter the same as above for CLMAF.
Remember to reset LTFTs when tuning in CL.

ill try and see what happens.. Just was seeing if someone had a decent tune with close to my mods so I have a good known starting point.

Be careful.

thanks.. but, i guess i am going to force myself to learn how to tune!

I got my new IFR table.. Now, Im trying to make sense of the "auto VE map" in the tutorial. Im stumped on #6 and dont see what its asking for.

and here are the IFR numbers I got..

I run FAST 36'ers and 60psi on the rail. I dont know what to put in for injected rated fuel pressure so I left it as 43.5

Do you enter in the MAP data too?

auto ve map you were asked to copy with labels looks like you didnt select the lables. basically its creating a map for your scan

[waterbug1999]

well, i loaded up just the new IFR table and it runs alot better. I drove over to a buds house, and he asked if i did anything with the tune, i said yea and he said he noticed it runs better.

Check out Marcin's (RedHardSupras) blog site. He has an excellent write up on recalculating from an IFR hacked tune. Lots of other great info too.

ok. thanks.
