You'd have to rebuild everything post-timer-change in the list which could be a handful of items, so there's a bit of overhead added, I was thinking this would also be an easy way to send a 5V signal to the injector drivers by just using one one 3. Toggle Navigation Welcome, Bing [Bot] Profile; Notifications ; Account (obviously ensuring the drive circuit can handle the loads). As of the January 2016 code release, Speeduino systems have an approximate 85% duty cycle limitation. This pulse frequency of the 5th injector would be a function of rpm. Good TPS, No RPM. - 4 injector outputs with dedicated injector MOSFETs, - 4 high current outputs - stepper motor driver optional module, - optional module (in place of stepper driver) for ETC You have no notifications. When using more than one coil driver per-channel, jump the board IGN output resistors and instead place one 15-ohm resistor in the line to each driver. A single smaller injector cannot supply the required fuel at higher speeds, simply due to limited available time. jpeg The primary value has to be going up yes, however the secondary does not. 3 board was the first widely available Speeduino shield and is suitable for many typical 1-4 cylinder injection and ignition Output pin injector 2: pinInjector3: 10: Output pin injector 3: pinInjector4: 11: Output pin injector 4: Direction pin for DRV8825 driver: pinStepperStep: 17: Step pin for DRV8825 driver: pinStepperEnable Speeduino Documentation. 4 for the stepper driver.

User mini profile. View Enter that latency (0. NOTES: Speeduino does not require resistors with injectors of 8 ohms or more. Speeduino feature injector drivers which integrate on/off control. Getting started. 0 ms you are treading in an area that is not very controllable, nor is it in that area for the fuel injector curve that is more linear. A large part of this complexity comes from the huge number of different ignition types that are available, with there being significant changes in the hardware used in the late 80s and throughout the 90s compared to newer designs. There will just be an unused squirt event on injector channel 3 but all calculations and stuff should be correct. To the best of my knowledge there still aren't any reasonably priced GDI drivers for any aftermarket ECU. jpg (581. All other inputs/outputs are working. If I run the above setup or the previous one posted (3 cylinder, 2 stroke), the results are the same. Sequential itself should be fine (once 5 and 6 outputs channels are actually supported), but it's possible that things like the 3D maps for individual trim may be a stretch on the Arduino for that many channels. the firmware is the latest version downloaded from github. I will use it because it never breaks, not my two in 40 years So I need two outputs to the amp. Settings Welcome, Bing [Bot] Speeduino does not natively support our trigger wheel although with alterations to the decoders. That should work, except you can't select paired with 12 injectors.

If using coil-per-cylinder, then best is one driver per-coil, so 6-channels. Also enter that value as 100% at 14 volts in your Injector User support forum for the Speeduino project. flat4power. I have noticed that if baro correction is disabled, it still reads some value and it jumps around 95 to 105 kpa, and if there in table is set something diffrent than 100 for fuel, then it might upset the tune alot, so I have zeroed (100) the table to avoid this "feature" Only when I noticed that it reads something other than 100kpa I did this and it fixed most of the problems Now when I input RPM signals, the speed response is correct from 0-8000, but the fuel injector does not respond. Cam position sensor When I put tunerstudio in test mode, the leds blink with the spark driver test. Settings Welcome, Bing [Bot] Its got a twin turbo 454 with LS1 coil packs and 16 42lb injectors.

The problem is that I can use the hardware test page to turn on any of the 4 injector channels, but which ever output the injector is connected to doesn't light up or click the injector. The High Z injectors are also referred to as ‘high-impedance or “saturated since they integrate a full battery voltage to regulate the open cycle of the injector. 4 The challenge I see using it with Speeduino is that while it generates a cam and crank signal, as it has a single igniter, I think the way it needs to work is the 4 IGN outputs from Speeduino would need to be combined onto a single line to drive the one igniter igniter. Once you have the firmware compiled and uploaded to your Arduino, you're ready to I just wanted verification on this so I can plan the number of injector drivers I can add to the board.
