Jaguar On A Budget, How To Do It On The Cheap!
Posted: Sun Aug 04, 2013 3:04 pm
Jaguar is a pretty well built setup that should be capable of surviving some serious abuse. That robustness comes with some cost, however. It IS possible to build a lower cost Jaguar, but it then becomes a much less robust platform.
This is my rough guide on how to be tight with your Jaguar build at the expense of future reliability.
But it WILL be cheap, which is necessary for some people.

This is my rough guide on how to be tight with your Jaguar build at the expense of future reliability.
- Leave out all rail clamp diodes for analogue inputs
- Leave out all LEDs, blocking diodes, and current limit resistors for them
- Use only one regulator and bridge the two power supply sections
- Leave out and bridge over the isolator chip
- Leave out the 5V clamp setup as without the rail clamp diodes, it's not needed
- Leave out the 5V rail thermal fuses, and bridge their locations
- Use an external map sensor for free from junk car, and don't install SMD sensors
- Leave off the MOV and bridge the reverse bias diode locations
- Don't install the MAT or MAF ADC sections at all
- Only install the drivers you need, for example, leave out 4 of the DPAK FETs, 2 of the SOT223 FETs, and one of the FET driver ICs, and all associated resistors, for a 4 cyl seq + wasted setup
But it WILL be cheap, which is necessary for some people.
