I've been a lurker for a little bit, posting here and there but thought i should introduce myself and explain my plan (and log my progress).
I have owned 40-something cars now, in varying degrees of awesome, and varying degrees of modification too. One thing i haven't really played with in the past is tuning ECUs. I have had a couple of cars with Link ECU and Power FC ECUs in them, but they came all setup and and ready to go by the previous owners (and not always with a good tune, even though it was done by a pro "tuner"). I also run a small website which has a full catalog of all my cars and everything i do to them. http://www.tasteslikepetrol.net
A while back i read a post on another forum i'm on about this thing called a Speeduino that they were building. A cheap version of Megasquirt. Upon further investigation i was hooked. An opensource, low cost full ECU? Im in!
I was already interested in the Megasquirt but put off by the cost, it ends up being not much cheaper than a full spec Link/Vipec ECU.
A few days later i purchased a few 0.3 boards, and all the components i need to build a couple of them. I have also purchased a couple of cheap ebay Arduino Megas and a 14point7 Spartan2. Everything is slowly starting to trickle in, and i'm getting ready to start building the Speeduino boards up now.
The catch at the moment, is that i actually dont have a car to put it in! I'm in the market though, so will be picking something up soon. The criteria really was something fun to drive, and somewhat compatible with Speeduino. So far it looks like ill be working with a Rover SD1 Vanden Plas EFI (swoon - Owned on in the past and love them).
So far the Speeduino boards and components have arrived, and my Arduinos arrived yesterday. To my dismay they have the rubbish CH340 chipset (I specifically tried to get ones without that chipset, but the picture on the ebay listing wasnt the board i was sent) so im working around that. Have ordered a couple of the Bluetooth modules to hopefully get around it (at the moment Tunerstudio sees the firmware on the Arduino but keeps reconnecting over and over). This is good as ill be able to use wireless tuning and dashboard too, call it a silver lining of sorts.
The plan is to buy a Range Rover ECU with the same casing and connector as the Rover, gut it, and install the Speeduino into the casing, and use the RR connector to connect the Speeduino to the existing loom. Some other wires will need to be added for various things (IAT for one) but shouldnt be too hard. Between the Speeduino and RR connector ill be using a 24-pin ATX connector, so that the Speeduino is still generic and isnt hardwired to the RR connector (in case i want to use the Speeduino for something else in the future, or upgrade Speeduino boards; itll be plug and play).
So thats where im at. Ill be using this thread to update my progress and ask for help when needed. Hope its of some interest
