Re: datamaster
I just finished doing the hotwire to the intercooler, depinned the yellow wire and used a thicker gauge wire stabbed Into the connection and hooked on to a fire wall ground. Funny thing is I used a thin wire and it did not power up. The pump is now pumping full time.
I will work on bleeding the CAC system for a air pocket and listen for air to come out.
I can see what your saying about the voltage going low. 12.2-12.5v it goes down to. I looked at the main power grounds they all appear to be good. I do not know what the ecm power mod is so I will search that out as well.
Maybe later on I can get a new log with the new plugs, IC hotwire/purged, oil change and power system reviewed.

Re: datamaster
One trick here is to wire a good fuseholder in line with that wire going to ground. If you're ever doing maintenance and need the key on, but don't want the pump running all the time (I also have a fan on my CAC), you just pull the fuse

Re: datamaster
OK that's easy enough. Something to keep in mind.. I figured if need be just unhook from where I have it held down.
I looked up the ecm mod? Is it a wire that gets cut and ran off the back of the alternator?? Or just a simple upgrade fuse in the fuse holder on back of the alternator? I am seeing a 15a fuse already. Also I was powering my laptop inside my truck via the console power point. I have a 12v-120 inverter, runs a 30a fuse nothing serious. Bought it just so I can run the computer in the truck. Wanted to add that ( just in case it may play a role on low power factor).

Re: datamaster
Keith Watson pointed this out to me a few years ago and it was surprisingly obvious.
Why run an inverter to a plug to the transformer for the laptop? Get a 12v car charger for your laptop. Less power wasted through the inefficiencies of the transformers. :2cents:

Re: datamaster
Mark, Maybe I will look into that.
I thought I was going to be able to do some late night runs,with cooler temps but I ended up having the truck keep dieing out on me and idling erratically. It would some times stall out, or if in park it and put in D it would just cut out. I read up in the blue supplement but the page went on and on and on for things it could be. I think It ended up being the fuel blend. Kind of strange but yeah...
What I ended up doing was 2 data runs. First log is the first run pulling from a light making a right turn road is desolate. http://www.mediafire.com/download/ngbgay230mat4c4/gmc_typhoon_4.uni
Run #2 was similar but on a main road. I was getting into it. http://www.mediafire.com/download/lbf7llydzxfik5x/ty_run.uni
Looks like the Intake temps dropped signifiganly since doing the IC hotwire. I stood out at the intercooler and timed the pump. Seems like it takes about 45 seconds to circulate? I heard what sounded like the pump hanging up, it just seemed like the pump was taking a while to circulate or I still had a air pocket. I timed it and it seemed to be every 45 seconds a new cycle of water enters the Intercooler.
From what the logs read looks like the spark retard is almost inactive. I feel like the truck all the sudden is " running way better " This time I believe the truck hit close to 23 psi.

Re: datamaster
I am running a blend.
I know Jimmy shook his head when I told him occasionally I put some race fuel in. I put a 50/50 blend of sunoco 260 gt and 93.
I'm only saying what I'm seeing, unless the log is lieing. Just like my battery voltage being low? Could these readings now be inaccurate?
I'm still learning but check the log for your self. There was a very small amount of knock.
I figured the new logs would tell all.

Re: datamaster
I missed you ran a blend, that would help. It still seems a little high but if the logs are clean then i guess you are ok but the high boost (23 psi) with 2 bar still is odd though?

Re: datamaster
23 psi with a 2 bar MAP is asking to grenade the motor. Either your setting in DM/TP is wrong and giving you false readings or you have a 3 bar in there somehow. You need to verify this urgently and stay out of boost until you know.
The whole point is that the 2 bar MAP sensor cannot read beyond 2 bar. If it can, it's a 3 Bar sensor or more. If it can't read the pressure, it can't regulate the fuel and :kboom:
The plugs are CR42TS or equivalent. Not sure what 43s are.

Re: datamaster
In DM, under 'Display Preferences', set 'Map Calibration' to "OEM".... You're actually running exactly 15psi max through the one log I looked at.

Re: datamaster
I actually didn't think it made a difference I did click around. After seeing 2-3bar I figured that was correct.
Some one like me needs to see :
-OEM
-2 bar
-3 bar
And not a combined 2-3 bar. I figured that was the. Prrect value.
Aside from that, how would you say the logs look? :kboom: ?

Re: datamaster
I just looked at those logs....
Like I mentioned in the previous post, you're running a max of 15psi in one log and 14.6 in the other... exactly what I'd expect to see in a stock truck. It also displays the shitty boost control we see in these stock set ups - you're only seeing 10.8psi when you get into third.
I would imagine it feels pretty doggy. Low boost in top gear with low timing (13 degrees) will make it sleepy.
Your intake temps look better Your voltage is still sagging a bit, but is much better. I'd still suggest the ECM power mod, or the injector harness mod that I do.
Very little KR, as I'd expect...looks like you're safe. The KR I see is probably something rattling (fuel lines, downpipe, motor mount issue, etc.).
Do one full throttle run and post that... it will tell us a bit more.

Re: datamaster
Yes, DM is used with a lot of naturally-aspirated cars, so some of the settings are a bit confusing. I discovered that OEM setting a long time ago right after I purchased my Sy and got the Autometer boost gauge installed - I knew something was screwy!

Re: datamaster
With the boost issue, do you think a forge gate would solve the boost issue being low through third gear?
A couple members/buddy's have gone that route and I have thought about it. Just deleting or unplugging stock sensor and setting up like a forge wastegate with a set boost range? Just something I was thinking about.

Re: datamaster
Everyone who has used one seems very happy with them. I've seen a data log from someone using one and the boost curve was almost ruler flat. I may go that route but have a few other things to try first, and would want to integrate it into the ECM.
