Jaycar selling some OK kits for cars

[666DAN]

Was just flicking through the new Jaycar Electronics mag and saw that they've knocked up a sort of PFC hand controller thingo for some new kits they've released!!!

Kits include:

Hand controller kit for digital adjusters (PFC hand controller-esque thingo)

Boost Controller Kit (Uses factory solenoid)*

Digital Speedo Correction Kit (for changes of diff/gear ratios)

Automatic turbo timer

Fuel Adjuster Kit (uses the AFM signal to do this)*

Digital Pulse Adjuster Kit (For adding injectors)*

Nitrous Fuel Mixture Kit (Controls nitrous injection, based on engine speed)

The ones marked with the * require the controller to program them...but for a DIY kit it's got quite good resolution...brilliant for those that are more interested in a product that works instead of visible rice appeal.

Go to www.jaycar.com.au for a squizz

has anybody tryed the boost controler kit yet?

Keen to find out more about these.

[DezertEagle]

If they were so good, everyone would be using them already.

The supposedly 'home made' Norgen Boost Controller is used a fair bit, it's proven and great boost controller.

Unless you wanna be a test dummy

[Warpspeed]

How could everyone already be using them, they have only been available for about a couple of weeks ???

No they have been around for a while.

The Turbo Timer is only $35, so cheap - wouldn't every man and his dog have a HKS/Greddy one now if they were that price?

The Boost Controller is $80 or so dollars + Hand Controller + Solenoid + No Product Good Will.

I'm just a little skeptical, that is my opinion and I feel I'm free to say so on a forum like this.

Isn't one more than enough???

[Squizz]

On a freakier note, I'm also Jay and I drive a Car...

[666DAN]

haha I was going to say that when I posted it...but I knew you'd pick it up sooner or later Should have put they were brand *spanking* new kits!

[Squizz]

You're a worry...

[Oosh]

I'm certainly interested in the speedo adjuster since i have a 4.3:1 diff.

Now for $80 the boost controller looks good, but it's another $60 for the hand-contoller, so if that's ALL you use for it's now $140 for a boost controller.

If you don't have a boost solenoid you'll need one of those too.

THEN you have to set it up, which if you don't have some sort of RPM/Speed and Boost data-logging is going to be a hit and miss affair, relying more on gut feel than real data, for on road tuning. Therefore most people will require dyno time for the setup which equals more money.

Suddenly a secondhand HKS EVC, or similar, with self-learning (which just needs a backstreet to give it a good thrash) doesn't look so expensive. Not to mention they're a proven unit.

Now i think it's great there's some aussie outfits getting in to this for a good price, and you could save a bit by sharing hand-controllers etc, but you need to look at the TOTAL costs associated with these things. Also i can GUARANTEE you which one will hold its resale value the better.

[funkymonkey]

or you could buy a silicon chip mag for about $7.50 (or free at a public library) and all the parts for about 50 bucks and build it yourself.

Also I have a wholesale acct with jaycar's distributor, which means I can get the handcontrololer for $40 and the boost controller for $55 if any of you guys want any of em.

Not everyone has the skill or will to build them.

[GTRman1992]

You have to balance the cost with risk. You build the boost controller wrong or it doesn't work boom. Same goes with the other kits. The also look like they are made the most cheapest way possible. Single sided boards, no ground planes...etc.etc.etc....

[666DAN]

Some people would probably get a lot more satisfaction from DIY...lets face it not everyone is a soldering iron champ....but those that are capable may well find this suits them.

I may take you up on that offer Shan, I'm interested in the turbo timer and boost controller

Hi guys, having built quite a few electronics kits over the years I have found the Silicone Chip ones can be relied upon to do exactly what they are designed to do. I am not a Julian Edger fan, but he did a lot of research and real world testing on these items. So I have a fair bit of faith that they will do as specified on the Stagea.

Over the Xmas break I am building;

the boost controller $80

the hand controller $60

the fuel adjuster $80

For a total cost of $220 (around half what an SAFC costs) I get to program, control and monitor, too good a deal to dismiss lightly. I will publish the results (inc dyno sheets) when all is finished.

Merry Xmas to all:cheers:

[666DAN]

Great to see SK, I'm a Silicon Chip/Electronics Australia nerd from way back (well as far as a 25 year old can be) and have found the kits to be excellent!

Can't wait to see the results!

[funkymonkey]

If anyone's that worried about using single sided boards etc, I can etch you a PCB if you wanna supply me with the materials. But yeah let me know part numbers and I'll get you the wholesale prices.

You can always be relied upon SK, good (future) work , despite my previous comments I'll be VERY interested in your results.

A turbo timer is only WORTH 35 bucks. If you open up a commercial unit, you'd be surpised how small the component count is and how simple the circuit is.

The also look like they are made the most cheapest way possible. Single sided boards, no ground planes...etc.etc.etc....

Why use a double-sided or a multiple layered board when a single-sided one will suffice? The kits mentioned do not use sensitive high-frequency circuits and as such there is no need for ground planes. Remember the art of designing is to do it in the simplest possible way, for the simplest things in life are the best, and easier to troubleshoot too, should the need arise.

So why DIY when you can buy a ready-made product? Because the process of DIY is enormously rewarding, addictive and you can learn so much from it. The journey is just as important as the destination.

Sydneykid, good luck and have fun building the kits. We certainly look forward to hearing the results from you.

The Jaycar boost controller is very simple. Unlike commercially available Electronic boost controllers, the Jaycar unit is not closed loop. It is basically an electonic bleed valve which can bleed different amounts at different RPM points.

It will never check the real time boost pressure and compare it to some target value as the commercial units do.

Also, a decent solenoid, like those included in Turst, HKS, Blitz etc boost controller would add to the cost of the boost controller significantly.,
