Roman Posted October 22, 2015 Share Posted October 22, 2015 Went out to make some doort noises tonight, had the hose for map sensor #2 mounted about 10cm in front of centre of the radiator Shows as being 3kpa above the barometer, (oh yeah, so I guess that's a 3rd map sensor...) could be higher with a bottom panel that seals that area in. Good place for an intake but I'll mount the hose closer to where my air intake will be coming from and see what happens.I guess that much was already obvious seeing how just about every factory car in existance gets air from there. But good to see it backed up with some numbers. Saw an AE86 on the motorway too which was cool 3 Quote Link to comment Share on other sites More sharing options...

yoeddynz Posted October 25, 2015 Author Share Posted October 25, 2015 Oh wow!!!! Yep. Im all for that. Very keen and been wondering when a cheaper alternative to ECUs would come out. awesome. Might have to get one for Viva wagon. Or that northstar engine Quote Link to comment Share on other sites More sharing options...
RevDWC Posted October 27, 2015 Share Posted October 27, 2015 Just signed up on the Speeduino forums, looks too good to not investigate for when Fiat twincam goes into Lada wagon. Quote Link to comment Share on other sites More sharing options...
anglia4 Posted October 27, 2015 Share Posted October 27, 2015 That looks ideal for my little low budget mustang project. I'm not really familiar with this stuff though. Say you get the v0.3 complete kit, do you still need an arduino thing to drive it, or is that part of the v0.3 board? Quote Link to comment Share on other sites More sharing options...
RevDWC Posted October 27, 2015 Share Posted October 27, 2015 You still need the Arduino board. They can be had from Trademe, AliExpress, eBay and so on. It looks like PCBs are a bit scarce right now, so it's a bit of a waiting game. 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted October 27, 2015 Share Posted October 27, 2015 I got E-throttle cruise control working.... hooooly moly it's awesome. Apart from just novelty factor, it's going to be awesome for tuning cruising ignition timing and having really really really really repeatable results. As in, set cruise control to XYZ speed, do a run on a flat piece of road and datalog it. Do the same thing again with ignition timing advanced further, (or cam timing) datalog it. Rinse repeat until you find the lowest average KPA values (Or lowest average effective duty cycle of injectors) Based on what is possibly some dubious maths it looks like last night I was getting 10.25l per 100km, when running ~30 degrees advance at cruising. Ideal ignition timing in this area is going to be closer to 35-40-45 degrees advance so there's going to be some economy improvements there for sure. Previously the car's acheieved 7-8l per 100km and the factory ECU used to smash timing in right to the point of knock (And beyond it, when I had knock sensor problems) I'm looking forward to finding a good spot to test with and having a play around this week. Something else that will be handy with E-throttle: 1. Push button on the dash 2. This switches to a 2nd E-throttle map which gives a max of (for example) 70% throttle opening, and turns on datalogging 3. Mash foot to the floor, engine holds at 70% throttle every single time for repeatability of tuning that region of your map. 4. Push button on dash again when finished and throttle goes back to normal and datalogging turns off. Should be fun. 1 Quote Link to comment Share on other sites More sharing options...
Lith Posted October 27, 2015 Share Posted October 27, 2015 Hadn't really thought about those advantages of e-throttle, that's really cool- at least for when tuning a naturally aspirated motor Quote Link to comment Share on other sites More sharing options...
Ned Posted October 27, 2015 Share Posted October 27, 2015 Some of you may be interested in this. For $120 it is pretty cool. http://speeduino.com/wiki/index.php/Speeduino this is pretty rubbish though and is nice as an academic thing if you just wanna learn about what happens and play around with a shitty engine on a stand, but shit if you actually want to run your car on it. Just buy a microsquirt for ~twice the money Quote Link to comment Share on other sites More sharing options...
downtrail Posted October 27, 2015 Share Posted October 27, 2015 ^^ this altho a great idea to play around with its not dedicated ecu hardware. Itll only be as good as the coding. one small slip in the maths and its game over. Quote Link to comment Share on other sites More sharing options...

Just buy a microsquirt for ~twice the money Why is it rubbish/shit? Don't bag someones hard work without justifying yourself. 1300loops/second and under 100uS timing accuracy at 10k rpm should be fine for most setups. It is still in development but I fully expect it to cut into the MS market in the future when it is a bit more user friendly. 2 Quote Link to comment Share on other sites More sharing options...
eke_zetec_RWD Posted October 28, 2015 Share Posted October 28, 2015 hey guys, Has anyone set up traction control on the new G4+ ecus? Iv got my Fury all wired up and ready to test out. Any trick tips? Also since i have supercharger i have installed a mac valve between manifold and BOV's. I have this running as a boost control vs wheel slip vs rpms. min pressure = 5psi max pressure = 16psi boost control on supercharger say what!

Testament Posted October 28, 2015 Share Posted October 28, 2015 would it be better to do timing retard instead? has a quicker effect on torque output and would be simpler/less wiring and hoses etc. sure either can be made to work just fine though but yeah no idea on settings /lingpost. good luck please report back with findings/graphs Quote Link to comment Share on other sites More sharing options...
eke_zetec_RWD Posted October 28, 2015 Share Posted October 28, 2015 Boost control mainly for overall power reduction. I do plan to use fuel/ign cut but I need a good testing ground for that. Its very fiddly to tune it seems! ps i did a dyno run with a couple of low boost patchs in the pull. Takes 100rpm to drop 100wkw so about 0.1sec Quote Link to comment Share on other sites More sharing options...
