I was at the junkyard to day and I cam across a 1997 vw jetta with what looked like electronic fuel in it. I was wondering if I could make it fit my 924 with only a little modification? or if this car wouldn't work are there any cars that might fit the 924 thanks

The 97 VW Jetta has a fully integrated OBDII engine control system. That is ignition, fuel delivery, and emissions.

I'm not saying that it can't be done, but doing it would take an experience mechanic, and a computer programmer.

And, if you have to ask, you don't have the knowledge or experience to do it.

yeah i figured that was the case or else why would people shell out the money for the mega squirts so i guess my new question is are there any cars the i could adapt systems from to make the 924 more reliable and updated a some what antiquated system thanks

Rather spend your money on a VEMS - it works out cheaper and better that MS, since you have the EGO integrated. Modifying another car's system will mean that either you know the system yourself inside-out already - ie you are an experienced tuner with that system, or be prepared to pay more than a VEMS just to get it tuned.

oh come on now, you can get one here -> http://fireandfuel.ca/content/view/17/84/ for only 1095 Canadian dollars, but you see, that comes with a wideband controller (still gotta buy a wideband sensor mind you) and some other stuff, so its well worth it................ nevermind that I converted my whole car to megasquirt for less than that....... *cough*

Understand they have capability for 2 (dual) O2 sensors but no idea of the associated hardware/ software.

Also has on board basic knock detector/ filter/ processor via a TPIC8101 IC that supports 2 sensors.

Raceboy can expand on the additional features and benefits of VEMS being familiar installing/ tuning them and a distributor.

However, as Min and Scorpio exclaimed, its very difficult to go past MS from a performance per $ and support perspective. A basic (MS1) at around 1/3 the cost, and especially if you have a knowledge of electronics (or some help) a comparable set up can be built at under half the price.
