CorollaGT Posted July 14, 2016 Share Posted July 14, 2016 My car has defi gauges and a Link G4 Storm - been thinking about the possibility of incorporating the oil temp and pressure to work together so that I can do logging and maybe lower rev limit temp dependent. Ideally the plan would be to piggyback off the Defi sensor wiring and tie it into the ECU inputs. Has anyone done this before? / have any pointers? I don't really have the ability to easily add more sensors to the motor unfortunately Quote Link to comment Share on other sites More sharing options...
Roman Posted July 14, 2016 Share Posted July 14, 2016 Surely your ECU would already have engine temp hooked up, otherwise it would run like crap when it's cold.So RPM based rev limit will be really easy to setup. Do you have a cable to the ECU and PClink installed? Download a copy of your tune and post it up, I'm sure you'd have a spare input on a G4 if you're running ITB NA motor. It only needs 1 analog input for wideband. Quote Link to comment Share on other sites More sharing options...
CorollaGT Posted July 14, 2016 Share Posted July 14, 2016 Whoops - left out oil temp / pressure! Pretty sure the pressure sensor on Defi stuff is 5v (3pin - positive, earth and return) so I should be able to tap into that one ok. Its more the wiring of the oil temp that I'm unsure of Quote Link to comment Share on other sites More sharing options...
Roman Posted July 14, 2016 Share Posted July 14, 2016 Dunno how CAN works on the G4, whether it uses the cable that your laptop plugs into or two of the wires on ECU. But that could be an idea to get all of those things logged. Use something like this (just randomly googled analog to can converter, there are probably better things out there) http://www.techmor.com/analog-to-can-module-ac-1-4/ So you can get 4 or 6 or whatever sensors for only 2 wires. I think the megasquirt people make a pretty decent CAN converter thingy with lots of inputs. Quote Link to comment Share on other sites More sharing options...
CorollaGT Posted July 14, 2016 Share Posted July 14, 2016 For anyone elses reference - I tested the Defi sensors and they're 5v so piggybacking them will be the way to go. Also found someone had spent the time to collect data on the Defi sensors so should make calibration in the Link easy http://bbs.22b.com/forums/showthread.php?8223-Defi-Sensor-Calibration-Curves 2 Quote Link to comment Share on other sites More sharing options...
kws Posted August 4, 2016 Share Posted August 4, 2016 If anyone is interested, i have started a project with a Speeduino DIY ECU. I have finished assembling it, have fitted Bluetooth and all loaded and connecting to Tunerstudio. Im really impressed with the capabilities of it so far, and its being almost constantly developed. http://www.tasteslikepetrol.net/category/speeduino/ I havent got a car to put it in yet, but if i play my cards right the car i want will fit in well here. 5 Quote Link to comment Share on other sites More sharing options...
kws Posted August 26, 2016 Share Posted August 26, 2016 Anyone want to buy a Speeduino 0.3.3 board or two? I ordered spares, and have a couple left. Will let them go for what they cost me, $25 including postage. Does not include components or Mega, just the board. Pm me. http://speeduino.com/wiki/index.php/V0.3.2 1 Quote Link to comment Share on other sites More sharing options...
fuel Posted August 26, 2016 Share Posted August 26, 2016 how much has it cost you all up including Arduino and components? Quote Link to comment Share on other sites More sharing options...
kws Posted August 26, 2016 Share Posted August 26, 2016 about $150 or so at a guess, with all the components from digikey. i did buy in bulk. Can probably get the components cheaper elsewhere, but digikey is easy. I also went a bit overkill, adding bluetooth, and a VR conditioner (wanted to cover all my bases). Also keep in mind that for best result you will need to buy registered versions of tuner studio and mega log viewer. Itll work on the free ones, but missing some key features (like auto tune).

kws Posted August 26, 2016 Share Posted August 26, 2016 Speaking of Speeduino, i did some more work.... http://www.tasteslikepetrol.net/2016/08/27/speeduino-v0-4-1-assembly/ 1 Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted August 27, 2016 Author Share Posted August 27, 2016 Im keen on a board. I'll pm ya.... Quote Link to comment Share on other sites More sharing options...
kws Posted August 27, 2016 Share Posted August 27, 2016 And all my spares are now gone. Look forward to seeing others progressing with Speeduino too. Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted August 27, 2016 Author Share Posted August 27, 2016 Who did you get your board from? The fella in Oz? 1 Quote Link to comment Share on other sites More sharing options...
RevDWC Posted August 27, 2016 Share Posted August 27, 2016 I've ordered the arduino and a Bluetooth module to go with the one I'm getting. Will order components set from Oz when my hobby account recovers from Gumboot Rally bender. 1 Quote Link to comment Share on other sites More sharing options...
bigfoot Posted November 11, 2016 Share Posted November 11, 2016 Ok, I have given up on my stinger and am now looking at a link atom. Where is the best place to buy from or are they all the same/go for the cheapest? Quote Link to comment Share on other sites More sharing options...
CamB Posted November 11, 2016 Share Posted November 11, 2016 I dunno who does good pricing on them but let me know if you find someone amenable to a discount because I want to buy a 5m A Loom and a B connector kit and maybe some other stuff.

Also link atom 950ish on tardme no loom Quote Link to comment Share on other sites More sharing options...
bigfoot Posted November 11, 2016 Share Posted November 11, 2016 Ok I am scared now - what made you give up on the stinger ?

Transom Posted November 11, 2016 Share Posted November 11, 2016 Ah ok I scored a 30$ old laptop with serial port and windows xp version that will actually read the help files that have more details than the basic instructions So hard to get any info on these Quote Link to comment Share on other sites More sharing options...
kws Posted November 15, 2016 Share Posted November 15, 2016 The wire for my Speeduino/SD1 loom arrived today, so i can start the proper planning now. Anyone got any tips that i should know for designing and making the loom? Itll be wrapped in self amalgamating tape, new weatherproof connectors, and new connectors for sensors/injectors. Will not reuse anything if i can help it. Going to design it similar to how the standard loom runs, with the sensor wires running down each bank with the injectors, depending on which side of the engine they are on.
