Yes, that'll work. The only reason I used an air compressor is because my car doesn't have an adjustable fuel pressure regulator on it.

Well thanks to Z, I have taken the plunge and bought me a data loger setup. I now have Innovate's Aux Box on order. Should be here in a few days. I'll be posting here for additional tips and tricks.

Pretty amazing that this thread is almost 2 years old! Tony, you are a trail blazer!

Tony

naw...Z is THE man.

But he can be scary at times... scary smart!

Thanks for the dialogue Tony / Z. This thread should help with my initial set up process. I just have to connect the wiring for the LC-1 / LM-3 / TC-4 / XD-1 / and calibrate the O2 sensor and I think I'm ready for the first fire-up of my SuperModel install.

My SharkTuner is on the way as we speake (if you'll pardon the pun). Hopefully, I'll have the Innovate instruments functioning when it arrives, so that it'll just be a matter of installing the ST and plugging it into the Innovate system to get the re-mapping done.

I'll start posting some data-logs as soon as I get things happening. It'll be interesting to see the initial data and the initial A/F map, and to compare the initial data with the post-tuning numbers!

Hello Brian,
Aren't you going to use the SharkTuner data logging when you receive it?

You can store the files for future reference, plot graphs etc.

Plus you can data log many variables not on the Innovate.....

BrianG

Of course I am going to use the logging capabilities of the Shark Tuner, John. Thing is, I 'll have to get the Innovate system working to the desired parameters first, since the ST uses the Innovate system as its WBO2 sensor. From reading the Innovate web-stie forum and the Tony / Z dialogue, getting the LM system set up might not be quite so straight forward as it could be. Also, the Innovate system can log some external parameters not monitored by the ST, like fuel pressure, boost, and temperatures.

This data, together with the ECU data straight from the LM unit will make for some very interesting observations about how the engine controller system works, under non-bost and boost conditions, both. I am very interested to see how the ECU deals with boost parameters in terms of injector duty cycle as a function of RPM and load and to see how the fuel pump keeps up with the demand, in terms of fuel rail pressure. It will be interesting to see if 6-10 lb of boost is testing the capacity of the OEM fuel pump, or not. It will also be interesting to see the temp responses through the intertcooler system, to determine whether the design capacity is actually sufficient.

Oh ya........ I'm a data ****, no doubt !!!

John Speake

OK Brian, good points. I think inlet temp would be very good to monitor, and also pressure drops through the system.

What are the problems alluded to with the LM ?

I'm installingthe LC-1 (x2) and the DL-32 in my 1996 RUF 993tt and I have a question, the manual show how you can use the existing o2 sensor bung and use the analog output to feed the factory ecu the values it needs.

Have any of you guy done that... use the stuck bungs and use the LC1's analog out put to signal the ECU?

I will be logging:
Boost
Maf
tps
lateral G's
and RPM

any advise woud be great,,, the car is all torn apart right now! I gotta have her back together by tomorrow night,

Cameron used the LC-1 simulated narrow band output and found it would be OK for a while and then act up.

He then had to go through the calibration process, and it would work for a while lomger, and then go crazy again.

I used the Tech Ege 2CO wide band "Narrow band sim" output to feed the NB O2 sensor input on my '87 S4. That worked fine for several months and a few thousand miles. I reverted back to the standard NB sensor only because I was done tuning and needed the WB for something else.

The Innovate should work to do the same. I have heard of some unusual problems, but that could have been due to something unrelated to the Innovate unit itself.

2V4V

I've run the Innovate unit in my 928 for almost 4 years now. (I also sometimes run another 4 channel datalogger that is laptop based to supplement the Innovate data.) I run it in lieu of the stock NBO2 sensor and have no output probs with the NB emulator function.

I have had one "open cell" issue, which a quick off-throttle reboot corrected. But I have heard stories where that can be more frequent.

YMMV,

Greg

John Speake

Hi Greg,
The issue appears to be with the LC-1, not the LM-1. Which type are you using ?

The TechEdge units appear to be relaible.

John

aggravation

Crap! I just ordered the LC-1 as part of the XD-16 stand alone kit, I was hoping to use it and the WB sensor that comes with it and replace my stock NB O2 sensor since I suspect it may be malfunctioning.

So should I install a second bung and only use the LC-1 wide band set up for the AF gauge and replace the suspect sensor with another NB sensor to feed the computer?
There isn't a whole lot of room in the H pipe to put another bung in but I could probably do it, the hard part would be putting it in next to the existing one to keep the body of the sensor upstream of the heat flowing off the pipe...I'm guessing that might make a difference.

By the way, excellent thread, I'm learning lots from you guys!

AO

That's how I have mine set up. But my O2 bungs are welded on the down pipes (one on eeach side) from the header to the X-pipe (H-pipe in your case). BTW, I still have my Aux box sitting in it's box. I just can't seem to find time to get out into the garage and fiddle with it.
