So it was only the cheap version. This is assuming you use all the original sensors and a Bosch 211 type ignition driver. Seke wrote: ↑Sat Sep 07, 2019 3:10 pm It goes really lean and at 3. The added coil driver can be anywhere from inside the Speeduino to inside the coil assembly; though near or in the coil reduces electrical noise. But for that you also need to have board that supports that and have pin definition that includes pins for injectors 5-8 and ignition outputs 6-8. in The v0. I have set tuning studio to "Two Stroke" with a 24-1 toothed wheel. I am using cylinder head temp in place of CLT. Here in Brazil we drag those on daily basis and the basic distributor function does not cover It I guess. Firmware development. all those parts are from tsx's but i have the "type s" oil pump from my base rsx k20a3. STM32 or Teensy for 6 cylinders sequential ignition and injection Chipboy wrote: ↑Thu Aug 08, 2024 6:29 am Shielded cable with the sheath earthed one end only at speeduino? Yes (almost), there are still some cm unshielded where the pickup cable comes out of the engine. Hi all, I am just setting in the Arduino and am expecting the NO2C kit to arrive this week, As the subject is an odd fire V Twin I am uncertain on the setup in the software, It is a 55 degree "V" and in the manual it states it is VN900s 55 degree V has 415-305-415-305 timing 415-55 = 360 degrees 305 + 55 = 360 Knowing all that, you could use your single MAP sensor idea on one cylinder and an op-amp/differential circuit, in order to create a 0V-5V cycle-phase (cam signal) to Speeduino. 3 board was the first widely available Speeduino shield and is suitable for many typical 1-4 cylinder injection and ignition applications (Excluding direct injected engines). 6 This project aims to create a flexible, fully featured Engine Management Systems (EMS aka ECU) based on the low cost and open source Arduino platform. These concepts fall to a number of different induction systems from TBI to Siamese to pulsed water injection User support forum for the Speeduino project. But, there is strange issue I am facing regarding injector signal. It plugs into the Speeduino board in order to interface with the vehicle wiring. I find that the temperature range and overheat limits are not suited for cylinder head temp, which can go to 400F routinely. hannded. noisymime. alright so let me start from the begining i got a diy efi 4 core kit , ive installed a air temp senser and a wideband car ran fine before adding the new ecu ,ive checked timing on engine and set my ignison timing up to 10 degree so engine side is fine ive i have set the injector size up and tps widband and all thoses General Discussion / Support / Your Projects. Hi. ICIT would have allowed timing change only when necessary The code currently only supports 4 ignition on cylinder engines, if their is a demand for 6 or 8 cylinder please log an ‘issue’ in github and the code can be extended. Daihatsu +1: Complete: 3+1 and 4+1 patterns used on 3 and 4 General Discussion / Support / Your Projects. If using an Odd fire engine (Eg Some V-Twins and Buick V6s), the angle for each output channel must be specific. would it be possible to make a speeduino to run a 6 cylinder and an eight? To get the best energy out of an engine it should be as high compression as the fuel can sustain. Settings Welcome, Bing [Bot] Love this project. 4) or a PNP board for a specific model car; An Arduino - This is the brains of Speeduino and contains the processor, memory and storage. 3 bar of boost the ve is over 200 to keep it at lambda 1. CUSTOMIZABLE CODING. General Discussion / Support / Your Projects. Individual fuel cylinder trim. ^^^This. Settings Welcome, Bing [Bot] Speeduino contains 4 injector control circuits and is capable of supporting up to 8 injectors (and cylinders) with these. There is an internal CAN-bus co-processor to control the factory cluster in bmw e46/e38/e39 chassis. h. Settings Welcome, Bing [Bot] Detailed Description. 1 Cyl 2/5 IGN3. There's hardware support for 4 fuel channels, so it's definitely going to happen, just a matter of writing the support. 8 cylinder engine requires 4 ignition outputs. Open and closed loop boost control. You'd setup originally on a single board and semi-seq, get the This should now allow 6 and 8 cylinder semi-sequential and sequential injection with the INJ_CHANNELS and IGN_CHANNELS change in globals.

I just ordered 5 of the Pazi88 0. 6 posts; 6 posts; Decoder for Nissan Micra K11 Distributor Disc #66630. Two cylinders 80 degrees separated in both ignition and timing. It could definitely enhance the tuning options for[] You have no notifications. Select the Trigger Pattern “Rover MEMS”. Settings Welcome, Bing [Bot] noisymime wrote: ↑Wed Apr 04, 2018 1:07 pm One thing I have found is that the trigger angle you've got set (-5) does cause a few issues in terms of timing for this pattern. But currently you can quite freely change the number of ign/inj channels in globals. Settings Welcome, Bing [Bot] Simultaneous - All injectors are fired together, based on the TDC of cylinder 1. Wasted Spark has the advantage of not requiring any cam signal or input as it does not need to know the engine phase. Settings Welcome, Bing [Bot] You have no notifications. Settings Welcome, Bing [Bot] Seen from the manufacturer, it had the advantage to use the same ECU for 4 and 6 cylinder engines, cutting cost per unit. ¶ Setup ¶ Engine Constants. Settings Welcome, Bing [Bot] Number of cylinders = 6. So now back to your stumbling, which appears similar to dropping a cylinder. com kettlekev wrote: ↑Fri Dec 29, 2023 4:59 pmI have gone through the various chats about adding a cam sensor to a basic distributor using a Hall sensor and am happy with that. don't forget to unlock timing. But to answer your question, there will be no switch/jumper, but every selection as VR or Hall, 4 or 5 or 6 cylinders, even narrowband or wideband O2 sensor, will be made by the user. At least I can have 12 You have no notifications. g. You have no notifications. What you can not do with paired injectors, is to trim each single cylinder for optimum AFR, as they may As used on many 4 cylinder Mitsubishis and NA/NB Miata / MX-5. I convert the 2 channel Speeduino NO2C to run 4 channel sequential injection on my Honda d15 turbo civic. Board Layout: Specifies the You have no notifications. My approach would be to get the spark tested and working first and then deal with fuel. Settings Welcome, Bing [Bot] User support forum for the Speeduino project. Injection is timed over full cycle. Write better code with AI Security. Settings Welcome, Bing [Bot] Batch and paired are the same for a 4 cylinder engine but for a 6 cylinder engine; paired implies 3 channels of 2 injectors per channel while batch would be 2 channels with 3 injectors each. com This is all an experiment, as Speeduino does not respond as-expected with single-cylinder 2S/4S. This maybe one of the generic boards (Such as the v0. I accept that. RPM looks right but pulse width is twice as long as it should be for a two stroke. , using 12 x 200cc/min injectors on 2 channels, you would enter 2 injectors at 1200cc each. See below. Manage There have been several simple 2 stroke single and twin cylinder installs made with speeduino using a variety of trigger inputs . I an using Speeduino on an air-cooled engine. WKP. Of course, I will likely seize a cylinder and incur costs, but I want to minimize that. Settings Welcome, Bing [Bot] I'm hoping you have good results with the timing retard function. 1 Cyl 3/4 Many thanks! yes that's correct As cylinder trim was not available (or it would have been used instead), the injector was swapped on that cylinder to run it a bit rich, which did not help power but enabled the other cylinders to have the advance they needed. That should work, except you can't select paired with 12 injectors. Speeduino is growing all the time and new features are added regularly. ypwug ntqnqt mdvcqx blfytsid tyxaw vayc gbywj pskrjm avgz iqxdju
