Jaycar's performance car kits	Fri, 11 February 2005 23:17

Hi all, I thought I might just post my current experiences with those relatively new car performance kits. The other day I bought 3 kits, the Digital Hand Controller, the Independent Electronic Boost Controller and the Digital Fuel adjuster. Over the past two nights (in my spare time basically) I have built the hand controller and DFA. I chose these two to build first as they would be the only two I could use right away Apon completing the two projects (which were fairly easy, but took a bit of time) I hooked them up to the only 12v power supply I had nearby... my computer... and the LCD screen on the hand controller came to life! It lit up, but there was a solid bar on the top line. I soon figured out that I had to calibrate the DFA in order to get the right results, a fairly easy task. Since the computer only had 12v at a fairly consistant value, I had to "trick" the DFA into thinking the "car" was now running. I did this by disconnecting the power source and reconnecting it almost straight away. As soon as I did this the LCD came to life and I saw exactly what I wanted to see - the DFA configuration screen. I had a quick play with the settings but it was getting late last night so I didn't get too much into it. The interface is very user friendly and tuning should be extremely easy. The value up/down buttons had two modes, one was very fine which stepped the values up in 1 unit increments, for fine tuning, and the other stepped them up in 4 unit increments. In 'View' mode I could tune every "step" manually, however in run mode it would seem I could tune "on the fly"... I can't see this being too useful unless I was on a dyno with the revs holding very stable. On the back of the DFA unit there is also a lock switch. This switch (which i stupidly installed upsidown... i was going so well too!) will prevent any changes from being made, so that annoying mate in the passenger seat cant lean out your engine Calibration (from the little amount I could do at the time) was very easy. All that was needed was a small flathead screwdriver to tune the variable resistors to the correct values. Tonight, I will be installing the unit into my car and I might even snap a few pics!
