Let me see if I have this right, please look

A little background, Ive tuned a few LS-1 cars with success using HP Tuners. You log with the program and re-flash the ECU. I ran a PLX wideband for WOT.
This is a screen shot of my Vette. I had the WOT AFR spot on.

Regarding the Buick, Do I log with say Powerlogger and adjust the MAF with the translator? Where do you retard/advance timing etc? Ive been reading, please don't assume I'm lazy and haven't been researching. Im just trying to figure out if I need a scanmaster, Maf translator and Powerlogger to accomplish my tuning goals. Want the ability to adjust fuel for cruise and WOT, timing, get rid of KR if needed.

My car is a 1987 GN, just hit 19,000 miles. Yesterday I changed the factory wires, plugs, oil and filter. My goals, I know your gonna ask. The car just needs to be a little quicker. Don't want to swap turbos, but would be willing to swap injectors, hot wire fuel pump, cold air kit, maybe loose the converter if it didn't make the car too loud, LS1 MAF, WB and other minor mods.

About me, I'm very handy with a wrench. I have supercharged Porsche's, LS-1's, can do head, cam swaps etc. Turbo's are a new animal for me.

One more question, I've downloaded the powerlogger program to check it out. I was trying to look at some members logs but can't figure out how to open them. Does the program need to be connected to my car?

Any help would be greatly appreciated.

Regarding Powerlogger....

You can download and save the file to your desk top and then load it into PL without it being hooked up to a car. You can then "play" through the live file.

You need to have an adjustable chip such as TurboTweak, this will allow you to tune using a datalogger. Also getting a Maf Translator is a good idea as the factory Mafs are a getting harder to get. The newer GM ones are a dime a dozen.

You can also fatten up or lean with the chip and translator in conjunction with an adjustable fuel pressure regulator.

First off, once you have powerlogger loaded, all you need to do to look at other people's files is..... Just click on the file in their post. You will then see a pop up asking if you want to run it or save it. I click run which opens another window showing the file in "my compter" type vew. Now just drag that .dat file into the plc folder.
Then open powerlogger, hit F3, load, and select the file you just moved to plc. Assuming you have the F3 options set up the same as the originator, you'll have good info (I.E. which wideband, which map, etc.)

Your options on setup are many. If you would like to stick with the MAF setup, you can go with the new Translator GenII, and in combination with that, order the Extender chip that best suites your setup (either extender, or extender extreme for 60# injectors or larger). The GenII will allow for normal maf operations, and will also use wideband tracking for WOT conditions. The Extender line of chips are best suited to operate with the Translators and allow greatest flexability.

For max amount of tuning capability and options, there is the Translator Pro, and Extender Pro chip. The translator pro will allow you to run speed density (no maf), also allows for part throttle wideband tracking (idle/cruise) in addition to WOT wideband tracking, along with the capability to control wot timing, closed loop boost control with many other features. For more information check the link in my sig.

And the Tuner Pro RT software that runs with Translator Pro isn't half bad either!!

Also you can tune the ve table by watching the bubble upon playback of your log, which is logging about 10 frames per sec. Review the corrections the pro is making and make changes and upload the new bin to the translator pro. Or you could run SD mode and leave the maf hooked up and read the error between them and dial in your ve table.:biggrin:

If you select use ve table #1 it will get you started for most GN;s as a base.

Great info thanks, leads me to a couple of questions. I understand I need a WB for WOT.

The Pro has its own logging software, so I wont need powerlogger?
The Pro can burn the extender pro chips?
The Pro can interface with my laptop or act as a stand alone tuner?
Do you have to pull chip out every time you log a run and want to make a change?


Dave, I checked out your sig. and read about the Pro, Thanks.

The Pro has its own logging software, so I wont need powerlogger?
Yes, and no if you want to do adjustments to the chip with an extender chip or similar adjustable chip you will need to see the blm's for your adjustments. The power logger will allow you to see more data and the ve and correction. I highly recommend it.
The Pro can burn the extender pro chips?
The pro does not burn chips, the pro is a device that will convert a map signal to a simulated mAF signal the ecu can use, and allow you to use bigger MAF sensors for more airflow.
The Pro can interface with my laptop or act as a stand alone tuner?
The pro can interface with your computer and data log as long as the laptop is running the software and you can edit the "file inside the translator pro unit" with the laptop connected.
Do you have to pull chip out every time you log a run and want to make a change?
The chip stays in the computer and you adjust the chip by using the accelerator and turning the ignition on and off, shifter in park, drive etc. The changes in the chip will remain unless your battery dies, or you unplug the ecu.

In order for the pro to work to its potential you will need a wide band connected to it. You are correct.

TurboDave is the most advanced user for this device so he can explain better than me............
