Has anyone tried the Autotap?

[98Wicked6]

On Thunder Racing's web page they have an OBDII scanner software package that supposedly moniters your sensors in real-time. Has anyone tried this before and had good results? Since my job is electronics related I'm planning on integrating a 486 PC into my car with a video out going to an Alpine indash monitor that is connected to my PCM. Then the OBDII Autotap will hopefully display the info on the indash monitor. Before I spend 800 bucks on the setup I was just wondering if anyone has tried anything close to this before. How well does the software work? Any help would be much appreciated.

On a side note, when I had the car dynoed we ran into the speed limiter every time. How do you get around it?

easy scan is much better than auto tap

it also is certified by obd2 compliance unlike autotap

I have always liked what I've seen of AutoTap....Kind of complex to use everything on it though. Once you learn it, it can be a good tool.

Autotap is a good tool to have, epsecially if you get serious about mods & want to monitor changes in your cars performance. Too bad the cable is so damn much :mad:

Autotap is a simple tool. This obd2 one above is probably overkill for most of you. Plus the price of almost $700 is a killer. Autotap is $250.

Mine just showed up on the doorstep today. The new laptop came a couple of days ago.

I will be able to tell you something about it in a few days after I play around with it for a while.

I A-Tap ALL the time.

My a-tap used to be Dom's, but then I borrowed it and my car fell in love with it.

Thanks for the info. Sounds like a good investment.

What simular options are available for the obd-I 3.4l? Just the auto-x-ray products?

I ran my new Autotap for about 1/2 hour this morning. Recorded two full throttle take-offs to 80mph. Interesting stuff.

Timing retard of -2 to -4 degrees at various points, usually in first gear around 4k rpms.

Timing advance drops to zero right before a gear change.

A/F ratio went from 14.7 to 11.8 - 12.4 under full throttle.

Also found from playing with the various gauges on it last night, that about two out of three times when I floor the pedal, it is not going all the way down. The tps is reporting 96-98% open. If I shift my foot just a little, I get 100% open. That could make a difference at the track...

Proved that my current thermostat is a 195 by monitoring the water temp.

Found out that my temp gauge in the car dash is not sensitive enough to see the difference between 180 and 210. I had been "manually" turning on my fans by kicking on the a/c for a few seconds at the track, then turning it off. But only doing this when I noticed the needle climb to a certain point. By this time it is really hotter than I realized, since 210 sits about the same place as 180 on the stock gauge.

Lots of cool stuff. Like the PCM estimates the torque output of the engine under the various operating conditions, and the autotap will track and report that.

I plan to monitor the fuel injector flow next, to see if I ever approach the max capacity of the injectors.

Sweet! That's the stuff I want to know! I ordered the indash monitor Thursday and everything should be in by Tuesday, can't wait!
