I've had a bit of an idea that I haven't presented because it might take folks off topic. Well I guess I'll do it anyhow. I'm sure you've heard of DLP for projectors. I don't see why one couldn't use a DLP chip with a laser pointer as your light source. Reflect the laser off the DLP and onto a whit...

There is no electronic boost control, but if you mean how solid is the gate control, perfectly. It rises up and sits at 18psi from 5k to redline. I have it plumbed wrongly there though, but that won't change how the gate holds pressure. With a small inner valve spring holding the gate open instead ...

Whats the boost control like on this??? I had horrible horrible problems with overboosting and my manifold had a MUCH better angle for the wastegate than yours does. After lots of messing around I had to go off the turbine housing to get boost to stay low and controllable.

Password protecting the flash/protecting the flash is something thats required for various reasons. Yep I'd be pissed too if someone didn't want to share a tune - I've shared mine to every other e-series owner who wanted to have a look. I'm more concerned about the safety of the car - ie I want to b...

Warnings appear if I try to do something that could damage my engine Such as? Advance the timing in a certain cell 1* ? Or change the trigger angle at all? or what? Most stuff can harm the engine and I think the softened world we live in already has enough "wear a helmet on a bike" type w...

This is going to be very difficult - but I'll start with some basics :) Tuning is done by entering data into tables Tuning tables have definable resolution and headings Tuning tables are on the same pages as live engine feedback which relates to the table After entering a number into a tuning table ...

If possible I would look at the addresses for serial and CAN or what ever else you end up using (within reason) like a bridged system - And all addresses are across all communications subsystems. If a message arrives for the EMS it doesn't matter if it arrives via CAN or Serial - if the address is t...

I prefer unsigned ints/shorts too this is why I use -1 (I'll explain) if you do this unsigned short blah = -1; then you actually get the largest value it can hold (255 for 8bit). In general for most networking protocols the broadcast address is always the last address and in software everyone instan...

Alrighty after reading through the old serial thread and this one fully I only have a few small suggestions. If this protocol is to be extensible it must have the ability to address multiple devices on one bus (for CAN) yet be small enough to not take up huge amounts of bandwidth. All I would add to...

Communications protocols are my thing :) Without knowing exactly what you want or how big anything is - this is my first approximation of what it should look like at a MAC level - ie firmware headers. Assuming some form of stop start is in the hardware. 1st Byte 4bits Destination address - 0000 is a...
