Can someone download this and take a look at it and let me know where I can improve on it?

The car is running just fine now except I'm getting some exhaust popping on decel like it's running way rich, but I don't know.

Let me clarify a little. This tune was set up by they guy who works on my car, not me. I do not have a datalogit, but he does. He did some tuning on it with my current mods. I just want to know if there is room for improvement.

Renamed the .dat file and added the .doc extension to get it uploaded.

 

It's pretty much the base map that comes with the PowerFC with a few minor settings changes. Nothing really going on there.

Thanks Dale!
There is supposed to be a little more timing in the motor, but still safe enough that it won't pop at 100C during the hot summer here in Phoenix.

 

Actually, I think the trailing map was tweaked a little, that was it - definitely not much change to be significant.

how much boost are you running? He basically reduced the split significantly, 9 or 10 degrees in many cells. Also, when you remove emissions stuff you're likely going to get those popping sounds.

 

The IGT (split) is very very dangerous!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!

 

Holy ****, take FCedit away from who ever did that! As Chuck said, that map is "Very Dangerous" X2

 

if you can't get the guy to fix it, re initialize your power FC.

 

Thanks guys! This is why I love this forum!

I'm running stock boost with the stock twins. I've just added the mods in the sig.

Can someone explain to me a little more about what the IGT (split) is and why it's dangerous. Also, if I'm running the car like this, what shouldn't I be doing with it while this map is on there?

I'm having some more work done on the car soon, just adding drilled rotors, lowering springs, and painting the calipers. I'll ask him about it and see if he can change it up.

Thanks for your guys help! I really appreciate it!

 

Personally I would not drive the car at all with this map.

Without getting into to much detail IGL and IGT control when the spark plugs fire. The Split is the duration between when the leading and trailing plugs fire. You should never have a negative split, it means the trailing plug is firing before the leading. This is very bad as it sends the flame front the wrong direction. The trailing plug is there more for emissions clean up than combustion.

Although there are several schools of thought on the subject most agree a maximum of 10 for the split with a minimum of 0 while in the power band.

 

Oh, that's nice to know...

I think I'll reset the ECU when I get home. When I reset it, do I have to do the idle learn again? I think so...

 

Yes you do need to reset it.

Re-initialize in the commander turb IGN off and then disconnect the negative, 10s than reconnect and restart, redo the learning process.

 

Do I have to disconnect the batt? I thought it was just turn on ignition, re-init the commander/PFC, turn ignition off, and done.

Start with the relearn on next start up?

 

I don't think you need to disconnect the battery before reseting the PFC.

 

Cool. I didn't think so...

 

Actually 15 split is stock but too retarded.
0 - 3 split is for NA engines, or idle and low boost for turbo engines.
12-8 split is for boost with 8 being HOT.

Use 3 split from P1 - through P11. Than start increasing spit so by P15 split is 10.
Then use what is safe and good, 10 - 12.

I have used 8 split for revs above 6000rpm on a stock motor.

 

Ok, so the next question is...

Is there any reason at all why he would tune the car like this? Is what he did all around bad or does anyone know there is some good in what this looks like?

Not saying I don't trust you guys, but there has to be some reason he did what he did. The car runs great right now, I don't get an hesitations at any speeds or anything wierd going on, so I'm just asking the question.

Thanks again for all the help!

 

Someone please chime in here and let me know some opinions! please?

 

Twokrx7 and I were the first to really push for controlling split and smooth split on this forum.

Even some of the famous tuners on this site were still ignoring split when they changed IGL. If you change IGL you also have to change IGT to maintane split.
But they finally "got the message".

Even the original and current maps on the PFC have screwed up split.


IGNORANCE!

 

Thanks cewrx7r1!!!

The map that you supplied is ok to run on my car safely then?

 

That map is not IGT but split and it is very good for the stock map sensor.

 

Did you get my email Chuck?

 

Not that I know of. If it went to the spam folder, I might have missed it during my quick check through all the adds for: viagra, meeting ******, meeting gays, free sex, free PCs, free TVs, etc.

 

Resent, next time I won't put : FR33 Vi4Gr4, meet hot women in your sity SeX SeX Sex in the subject line.

 

Come on Chuck, you don't like reading miles and miles of text about these VERY important subjects?
