I installed the catch can the other day. I took me a long time to get it on, mostly from putting my own hose clamps on the tee under the throttle body. In the end I had to take my clamps off to get the tee where it belongs. Its easier to thread it from the passenger side where you can actually see a little under there and be sure to have plenty of light or you'll know how frustrated Helen Keller must have been most of the time. The Dashdaq is still being studied. I don't have it figured out yet. Sometimes it works and sometimes the gauges don't read the signals. I did some data logging as an experiment and all I have is flat lines. When it working its pretty interesting. Do I have to scan for the signals every time I start the car? I'll figure it out when I have more time to play with it. How about a few Sunday pictures?

I am going to install mine this afternoon after work...its getting ready to rain, so this will make for a good project...I will try your way...thanks...

 

if you move the dashdaq from one car to another you will need to do the "find signals" step for each car. flat lines? i assume your trying to view on the dashdaq itself? gimme a few hours as ill be making some pretty graphs for tom before we install the new parts today and ill post up the steps to display them.

btw, car is looking good!

 

Right you are, I was trying to view on the dashdaq. I don't have a memory card reader and was taking a quick tour trying to learn how to data log and view it. By the way, the new extreme air filter is even louder than the original filter. You can hear the supercharger even at idle, which I like.

I need to get to the track to see if it reflects in my times or mph before making more changes.

Les, you really should pick up a card reader. You can get them on ebay for less than $10 shipped. It saves sooo much hassle pulling the dashdaq out of the car and plugging it into the PC. Just turn the dashdaq off, pop the card out, pop the card into your USB card reader into your PC and blamo - you copy the logs over and open them up in Microsoft Excel.

PM me if you have trouble. I can give you some directions.

Also, if buying a card reader from ebay, don't but the REALLY cheap ones that look like this the attached photo. They are total crap and don't work half the time.

 

i picked a 2g sd card from office depot for $12, it will take up to a 4gig card but they didnt have them in stock that day.

im still working on making these into pretty graphs for ya. ill post up the steps once we get it figured out, as of right now we have the data, just not displayed into the pretty graphs yet.

 

I've contacted Zeitronix for a converter that will change them from excel files to zto files. The converter online wasn't working, so they were going to email me one that does. Does any one have a working converter? Mine saves them in zto files, but was helping someone with a dashdaq.

 

I did a quick log to see how it works. The first column is MAF. The second is MAP and the third is RPM. This is after installing the Code3 aluminium pulley yesterday. So, those that know, how's it looking to you?

 

if you have the dashdaq save as a dif isntead of a csv you can open the files in logworks 3. i havent been able to get the graphs nearly as pretty as the zt-2 software yet but am working on it.

 

dont bother with MAF, its just a calculated value from other peramters, we dotn care about that.

i want to see rpm, tps, afr, boost (map), iat, coolant temp, timing

 

Taking notes Rob. So is the boost I'm seeing what you would expect? Oh, I got a 4gb SD for $10.00 but the card reader was $25.00. I almost never work in Excel but I'm learning how to import the data into a graph for easier interpretation. The fun never stops!

Les

 

we need to do the conversion on the map for ya, im going to go thru the conversion again and send it to you

 

31.2 PSI - 14.7 PSI = 16.5 PSI at redline, I think thats how it works. No matter, the car is running great. Now I can give my Porsche buddy a ride. Oh Rob, about that teaser pic, how about some details? $$, color options, etc. I need to spend all I can before I'm unemployed, afterwards I won't dare.

I did some data logging today. The weather is damp and drizzly but I managed to find a few dry patches. My first full throttle pass I was seeing 18º BTDC in 1rst. which dropped to 13º BTDC right before the shift to 2nd. It shifted early because the tires started spinning. After the shift to 2nd. it was 19º BTC for 1,000 rpms and then dropped to 14 to 15º BTDC until the shift to 3rd. I may have been loosing traction again. (I really need to get sticky tires for the track)

The boost jumped from 6lbs. easing on the gas to 15.6lbs. instantly when floored at 3357 RPM which climbed to 16.5 lbs at 5112 rpm to 5976 rpms where boost dropped right before the shift. I drove a mile after the run to put gas in the car, popped the hood open and the belt was too hot to hold in my hand. However, no obvious visual signs of slipping. But I think it may be slipping. Could someone without a pulley take a spin and then grab the belt so I have a reference point as to what is normal?

I know some of you data log all the time and am curious if what I'm seeing is more or less normal.

Today I did an experiment. I took the car out and got in a sprint to 70 mph with the coolant temp at 180. No good. I appears we have a threshold to pass before the car will perform. I logged 5º less timing across the rpm range and the car short shifted at 5500 RPM. I'm convinced the car will make more power at a cooler temp but perhaps 190º is a better place to start. I want to try warming the car up and then letting it cool down to see if that makes a difference. I drove a mile before I could make the test so the car wasn't "cold" but it hadn't gotten hot either. Anyone know what the threshold temp is? Is it transmission temp? Some other temperature threshold? Is there a stepped threshold? In data logging I've only seen 6048 rpm once. I had put that down to the slow sample rate of my version of the dashdaq (I need the latest software, it logs every 3ms instead of every 5) but perhaps there's another parameter involved. Any knowledgeable enlightened blessed individuals know for sure?

I wish someone would send me one of these so I could make something custom out of fiberglass for it
