autotap

anybody here use autotap 3.1 for vista? I have it but i cant get it to work properly. having a loss of communication error after it downloads dtcs and parameters.
Tech support wasn't that much of a help any thoughts ?

There is a tech at AutoTap named John. He's pretty helpful. Call on Monday and ask for him (hope he's still there). I'm running version 2 on XP, works fine for me.

Are you able to detect the vehicle at all? Or is it just the DTCs you're haveing trouble with?

in my explorer it works fine start to finish, on the riv just dtcs then parameters ( gathers vin # also)then loses conection i was talking with a joe seemed nice but not to helpful

Oh.. maybe his name was Joe. It's been awhile. I think that's the right guy.

Try manually entering the VIN# and/or software serial# for the Riv.

thats the one thing i haven't tried yet good idea. K.I.S.S right ( Keep it simple stupid)

I had a lot of issues with mine, too. But once it works, it works well. I think you'll like it.

Did you get the GM extended parameters?

ya i believe so , its the kit on there website for 399.00, it picks up around 150 diff. parameters

You got it! Let us know if you get it working or not.

hey just went out hooked everthing up deleted almost all params except for about 10 and now its working! what param shoul i load 1st. also have you ever check the odom reading through autotap? its reading about 350 miles less then the car odom.

For general scans:

1) IAT
2) Throttle %
3) RPM
4) Timing ADV
5) A/F Ratio
6) LTFT
7) 02(sensor 1)
8) MAFF
9) MAP
10) KR

Also, if you can log: MPH, BAR Pressure, Coolant Temp, Gear... it's nice to have, but not required.

For tuning, you might want to only use a few so the data gets logged more densely. If you try to log 12 items at once, it logs each one more slowly. If you log only a couple, you get a finer resolution for those two.

as far as the kr goes its kr not sensor counter or active channel right, does anyone know normal trans temp

Normally trans temp runs around or a little higher than your coolant temp.

right, it's just KR.

thanks guys im going to get some good reads on the way to easter dinner later on.

Ok im not sure how to transfer the data to here so ill just post one section


Rpm -4312
ig im adv - -10
iat- 46 F
MAP- 45.5
MAF Rate- 22.387 lb/min
02 bank 1- 870 mV
throt pos ang- 73.3
speed -99
air fuel Ratio 11.2:1
ltf1- 7.8
baro pres-29.5

any thoughts probably cant tell with such little info, i didnt see any kr till deceleration jumped to 2 then nothing once

We need to see these parameters vs. time. A table or graph is needed to show this. I usually export into excel, but there are other ways.

Tip: don't use hyphens to separate parameters from values. Looks like neg!

Not sure what that means, but normally KR should be zero.

I had troubles with v3.1 so im using 2.0 now, anyways, could someone explain how to export to excell or some other options .
thanks
