Did Some UTEC Logging - Mind Taking a Look?

[HomieG35]

This was a 2nd gear pull on my 2004.5 ProCharged G35 @ 7psi with the UTEC, 255 Walbro, 720cc injectors, SGP Racing return fuel system, and SGP valve body. I stayed on her through the 3rd gear shift (chirped 'em, yeah!!) and then let off right after.

A/F was a steady 10.3 -10.5 (yeah this high 80*F - 100*F weather is kicking my ass)...

Thanks for looking. Now, I know what each column means... but I don't know what is good and what is not... as far as timing, etc... This was my first time actually doing my own (tuner normally just looks over it). So some experienced opinions from outside sources would be awesome! It's been about 6 months since any kind of tuning...

[QuadCam]

use Logger 1, it gives you more info when logging. Also, you may want to consider some other software so that you can log you A:F info along with the UTEC info. try the UTI software from www.jeffsoftware.com. (I am assumign you don't have the TXS Tuner wideband.)

also, with youe A:F so rich (10.3-10.5) in the hot heat, you may want to consider using the temperature compensation in the UTEC to pull some fuel out during the hot days.

also, looking at your log, it seems like you Tuner has some of your paramter set rather oddly. In your log, it looks like you never get past the 20% load column. You can certainly give yourself better resolution and accuracy by adjusting values. Read the UTEC manual about 3-5 times and see if that helps you understand how it works........then you'll see you could set your utec up to better work with your current configuration.

finally, your post says you have a 7 psi setup, but your log is showing you only are maxing out at 5 psi.

[tranceformer95]

Just wondering how exactly do you datalog with the utec?

[frankie945]

buy a wide band for the utec so you can see your AFR... it is alot easier to read and understand For tuning

[gothchick]

need a wide band for that log to mean anything.

[HomieG35]

I have an AEM wideband

[QuadCam]

buy the UTI software from www.jeffsoftware.com

with it, you can log your AEM wideband and the UTEC info together. you have to connect them both separately to your lapto and the software merges the info together so that you can have useful info!

[athenG]

I agree with Quadcam.. also please data log on higher gears like 4th or 5th. If space is not enough space then at least do a 3rd gear pull, 2nd gear just go so fast. Im pretty sure your temp compensation isn't set right at that temp so you may want to fix that. If you are only running 7psi then at least set your Map max value to 8ps or 10psi so you can have a better resolution for better tuning. Timing is also set very conservatively especially at the higher rpm.

[QuadCam]

holy jesus...that timing is really low.....9 degrees at 6000+ rpms. I didn't even see that. I am not used to looking at that particular logger

lol... that is the first thing that caught me and combine that with 10.3:1 A/F

[HomieG35]

I'm not the tuner, SGP is. Is the timing just overly conservative (because that's how I wanted it) - along with a rich A/F (although in the winter months it's 11.3-11.5, so I know it's too rich right now).

This was my first time logging, so there is some good info here, but I'm gonna need a little of your help, and time because I've never, ever worked my way around the UTEC. If you're just now looking at the timing at redline, then all other posts before that are pretty much pointless... because who knows how long you actually spent looking at it... You didn't even manage to message me back, yet can still post in here. Thanks!

The car only makes about 320whp, which doesn't matter because it hardly gets driven and it's a ****in ProCharger... not really a 500/600whp monster there... and never can be with this setup...

Thanks for all the info though... I'll try to figure it out I guess...

Who are you directring this at? I PM'd back to you, and I didn't see the timing because that is not a logger that I normally use. I use logger "1" which gives you all info except AIT and coolant temps.

the timing seems exceptionally low, especially for 5 psi. remember that "conservative" timing is a BS term. back your timing too far back and you will increase your EGTs....
who knows, maybe you have super high AITs, and the low timing and fat fuel curve were a necessity. without truly knowing what was going on when your car was tuned, it is hard to say why the tune was done the way it was done.

Finally, I can only assume that since you are posting your log results, you must be questioning the tune that SGP did for you. By asking everyone here to examine and respond to the info you have given them, you are opening yourself up to all sorts of ideas, hypotheses, and opinions. take them all in, and sort it out for yourself.

[HomieG35]

My appologies.. I never got PM back - I've been looking out for one try resending I'm sorry.

I don't question the tuning, I just want you guys to know that I didn't do anything to do the car and just learned to datalog. It's been 3 seasons since the last time SGP touched it, so I wanted to know how the tune was holding up - or if it needed some kind of retune.

It's just frusterating (and I knew this would happen), I used to be 1 mile from SGP so dropping the car off for whatever wasn't an issue... now I'm 250 miles away and you gotta break down what your saying in dumbass terms so I can understand. You keep talking about temp tables and resolution and I have NO idea what you're talking about, lmao. I'm too scared to mess with anything thinking I'll be stuck in BFE East Texas and won't be able to get it to a tuner!

I'll download the programs, and get some more gauges (wideband, boost, and fuel pres. is all I have right now) in order to get some more help and understand more about how to do basic changes to my car without messing up the tune since SGP isn't just a short drive down the road.

Thanks again

[Hoooper]

the best thing you can do is read. read everything you can find about the utec and tuning it so that you understand it completely. manuals and other peoples instructions from other threads will help immensely

[QuadCam]

the best thing you can do is to read the UTEC manual over and over and over...until you understand exactly how everything operates int he UTEC. I know it sound ridiculous, but it works. I took my manual with me when I went on vacaction. when I came home, I had read it over and over so much, that I knew exactly how I wanted to set each "parameter." The manual won't help you with tuning, but it will help you understand the importance of each parameter.

for example, you will understand why you will want to change the "MAP Maximun value." Guessing, I would say that yours is set to 20 psi. On a motor that is only going to see 7-8 psi, you are severely limiting your ability to fine tune your setup. On your setup, you should probably set it to 10 psi.....just to give yourself some room if you decide to up the boost int he future. by lowering the upper limit from 20 psi to 10 psi, you have basically doubled the amount of "load sites" that you have available to you for tuning.......thereby doubling your "resolution."

Have fun with it!

OP,
set your Map Max value to only 10 so that you'll get a better resolution also you mentioned that your A/F in the winter is around 11.3-11.5 which is pretty normal and conservative enough in my book. This lead me to believe that SGP did not set your Temp Compensation since now you are getting low 10's in the hot summer days. I don't blame SGP since it is hard to replicate that range of a temp in the dyno shop so you have to go back or set it up yourself. Like Quadcam said timing is really low especially in the higher rpm, can you check your Temp Compensation in Utec if it is adjusting the timing also? You don't want Utec adjusting timing when it is compensating for the IAT. I think you should go back to a tuner since there is a lot to be tweaked and I think you have a lot more power to squeeze out of that setup.
