What the purpose of powerlogger with scanmaster?
Well if you are using a wideband, as I think any turbo Buick should have, one good thing is you can use the 02 mV side of the Scanmaster to display your wideband readings. This allows you to have one less gauge in the car. Plus you can glance at the Scanmaster on the fly and see what the wideband readings are in conjunction with if any knock is being pulled or not.
Okay a little confused so let me just ask it...Would it be worth it to buy a scanmaster and power logger for my stock motor or should I just get the scanmaster for now. I wanna slowly build up the car but Its gotta be a daily driver. Let me know what you guys think, you know better than me.
If you want to be able to see how well your engine is running by having the ability to plug a laptop into the ECM to "record" the info the ECM is seeing, to allow you to go back thru the log after you return home from making a pass, and see if there are any hiccups along the way, then yes.
Before I installed my powerlogger, I would occasionally have some KR pop up on the Scanmaster, but other than that my car ran really well/pulled like a bat out of hell. I eventually installed a wideband and would "try" to glance at both the Scanmaster and wideband (had them sitting together) while making a WOT pass down the track or road, to ensure I didn't see any KR pop up on the screen (that my audible alarm didn't pick up on) or maybe the 02 millivolts/wideband numbers didn't drop below 780 mV/11.00 while running on a WOT pass with the alky going.
Of course if you've ever tried to keep an eye on the ever changing numbers of a Scanmaster or wideband and memorize them in your head while on a WOT pass while trying to concentrate on the road, you would know this is in itself a very difficult thing to do.
Anyways once I installed my powerlogger, and I was able to start "recording" what the ECM was seeing, then I could make a WOT pass (while listening for my audible knock detector and occasionally glancing to see if any knock was popping up), and then once the pass was done, stop and go back and review the run on the laptop to see if any knock was detected, or if the AFR's from the wideband went low for some reason....plus I could detect when the knock happened, at what rpm, at what MPH, at what AFR, whether I was in 3rd gear or not, at what engine temp, if the engine radiator fan was on or not...you get the idea.
To say the least, I learned a few things that were going on that I did not know were happening at all. Things that could use an improvement on. Plus with the powerlogger if I'm not sure about what I'm seeing on the files, I can post the files here and someone can/will review them and point out something they see right or wrong.
Also the Scanamster by itself displays it's info really slowly, updating itself every second and a half if I recall correctly. With the powerlogger you also receive an upgrade chip for the Scanmaster which allows the Scanmaster to display it's info pretty much instantaneously.
I know I got long winded here but hopefully this supports your decision to whether this is for you or not. Perhaps they'll make a sticky out of this. :smile:
