Re: Hey, look, i built something! Neds MicroEMS
Hi Ned, Congratulations on your new design! Please keep us informed as you progress through testing and such. I took a look at the schematic, and if you ever decide to do a "Rev 2", I think that I could offer a few suggestions for improvement. Do you have a BOM you would be willing to shar...

Re: Jaguar 0.7-alpha release candidate discussion
Hi Andy, 1) What was the reason for this change - •Changed output LED protection diodes from 1N4148 package to 1N4004 (or other 1N400x) package. My only minor concern is that the 1N4148 is a fairly fast recovery diode while the 1N400x series are "slower" and typically used for general 50-6...

Re: My 87 toyota supra hardware build
Hi Via, Do you have a schematic of the Zeal Engineering Dual VR board? I took a quick look at the LM1815 and it appears to have a few configuration options and outputs and it might help to know the Zeal board implementation. Have you taken a scope to the outputs of the Zeal board to look for anythin...

Re: My 87 toyota supra hardware build
Hi Via, I am trying to follow this thread but am confused / ignorant regarding your CPS. In your first post you mentioned NE, G1, and G2. When I Googled this, this seemed to imply a completely distributor based setup which contained three, single ended VR sensors. But in your last post you mentioned...

Re: Bandwidth of Analog Inputs
For what it's worth -
The Freescale guide KT33812ECUUG lists the following low-pass values -
On / Off or temperature inputs = 100Hz
O2 = 500Hz
TPS = 1.0kHz
MAP = 5.0kHz
Thanks,
TonyS

Re: Jaguar 0.6-alpha Assembly Guide
About the Pxx, if it's not written on the board, ....The board should mostly document itself, especially at a user/connection/configuration level. "Pxx" means nothing to anyone?? I'm following the Jaguar schematic. Pxx denotes conn-1, a single pin connector. I can't seem to find any direc...

Bandwidth of Analog Inputs
As I know very little about what it takes software-wise to run an engine, I am curious as to what impact the bandwidth of the analog inputs has on performance. I assume that the bandwidth of a particular signal should be limited to as low as possible, without impacting performance, in order to filte...

Re: Jaguar 0.6-alpha Assembly Guide
Step 2. should probably mention placing a resistor between the voltage source and the pcb (like in the picture)

Re: LSU4.9 Sensor Simulator
Fred, I need to provide some details / guidance to the production test group as to how to test the basic functionality of a wideband controller that is part of a product that I am working on the development of. Unfortunately, I am not free to provide any other details. Alan, The request for a suitab...

Re: LSU4.9 Sensor Simulator
Hi Fred,
I seem to have caused confusion by mentioning the narrow-band sensor (I unintentionally do that sometimes : )
I want to fool a wideband controller into thinking that it is successfully controlling a wideband sensor.
Thanks,
Tony
