I would say the blanket makes no measurable difference

I'd agree with the old fart.

Now a 2 step is another matter.

Light the first bulb.  Ease it up and light the second one and then just put it on the floor.

So I pulled the powerlogger off the board and cleaned the connections and all was right as rain.

It's a good alternative to the HR parts and stuff bar.

And if I goes to 255 at w0t?
You can give it some taps with a screw driver handle and see if it stumbles but the scanmaster is much more accurate.
Probably time for a translator and new style maf(much more reliable).

I don't care for the "tap test"  It can kill MAF's too especially the stock style ones.  Just look at the data.

Well I think I have the mechanical and the PL reading almost identical. At least within .1 of each other which is great. 


Anyone know what this "smoothing" is for? I see in the analog input drop down you can select light, med and heavy. Is this to stabilize the graph readings? Man this stuff is a guessing game for an ol computer illiterate fart like me.

It just averages out the readings.

I guess you could log  the 5v rail to check it.

Not a half bad idea.  I guess if I get the right one. 

I don't think it's a real bump because it wouldn't go with the MAF, IAT and MAL randomly jumping around too

It's ok............ ......found it

Goes in the PL.ini file

Do you know the max pressure of the sensor.  You'll need that

The following is for Julio (alkycontrol's) sensors 0-150 PSI

[CustomAnalog4]
CustomAnalog4N ame=AlkyPressure
CustomAnalog4L ongName=Alcohol Pressure
CustomAnalog4T ag=AP
CustomAnalog4G augeMin=0
CustomAnalog4G augeMax=150
CustomAnalog4G raphMin=0
CustomAnalog4G raphMax=150
CustomAnalog4M inValue=0
CustomAnalog4M axValue=150
CustomAnalog4M inVolt=0.5
CustomAnalog4M axVolt=4.5
[CustomAnalog5]
CustomAnalog5N ame=FuelPressure
CustomAnalog5L ongName=Fuel Pressure
CustomAnalog5T ag=FP
CustomAnalog5G augeMin=0
CustomAnalog5G augeMax=100
CustomAnalog5G raphMin=0
CustomAnalog5G raphMax=100
CustomAnalog5M inValue=0
CustomAnalog5M axValue=150
CustomAnalog5M inVolt=0.5
CustomAnalog5M axVolt=4.5

General Buick Tech / Strange Scanmaster Readings

« on: May 04 2017, 07:02:20 PM »

I pulled the TR out of hibernation last week for a couple of cruise in's this past week.  curiously I was seeing some light KR at cruise with no load.  Intermittent 0.1 degrees.

Last night it got worse.  0-23degrees now I'm sure it's not real because 23degrees would be rattling like a can of marbles 

But also random readings on the AT, IAC,

And an intermittent MAL 25.  (That may be consistent with the AT bouncing around)

Hoping that reseating the powerlogger would help.  We shall see.

Seems like after that the next step is one of the 5V sources from the ECM. I think ATS and MAF are on the same feed.

Guy in high school had one with a 100HP dry shot of nitrous.  Hit it one day and drove over the crank.  Sealed the hole in the intake and took it back to the dealer for a warranty repair. 

And they did it.

it's a strain gage sensor so it can flake out electronically too.  You'll see it like in the output.  Most fail by leaking.  Apply 20PSI or so and I'll bet you can hear it leaking past the body.
