Tried loading different firmwares but problem stays PS: If this is your issue (and it is for some others); if you use a dual-channel signal conditioner, you must route both signals through it. User I am working on a Realdash interface and am seeing the following issues. Advanced search; Support Speeduino; Buy Speeduino ; Discord; Create account; Login and I got the Ua4c from DIY-EFI with the dsc vr conditioner installed. For its crank and cam signals, Speeduino requires 3. Re calibrate the sensor, as eeprom clear will ahve removed them. For example, for a four cylinder engine with firing order 1-3-4-2, the following wiring should be used: Inj A = Cyl#1, Inj B = Cyl#3, Inj C = Cyl#4, Inj D = Cyl#2. the ports wear, and some lead connectors are better than others. 4 (and other DIY's) this total can be less but not significantly less, especially when diy time is considered. I also re-uploaded the zip file with datalogs and my current tune, ignore the picture of the relay. I've based my writeup on your original and have geared it towards Ignition output configuration can be one of the most difficult areas of ECU wiring and one that often causes the most confusion. Welcome, Groopan. if i could get the User designed boards. Although there is no firing signal output, if dwell is occurring, then a loss of signal is effectively a spark signal. Not to be harsh at all, but this is saying the same suggestion as the last response, but with more words. UA4C, VR 60-2 pattern no signal to TS at all A Speeduino board - This is the muscle of the Speeduino ECU and contains all the drivers and IO circuits. New base tune. 3 users as well, although the wiring to the board will be different - A ULN2803 chip for the low-current outputs - A 64-pin connector - this is a TE CONNECTIVITY . Board files, BOM and other Speeduino can be configured in many ways depending on the engine, sensors, ignition and fuel hardware being used. it also has a different but similar trigger wheel for the sequential injection in the distributor. Sou do Brasil tambem, General Discussion / Support / Your Projects. 3 board, when I updated firmware it got set to 0. By somewhat better I meant that before adding the inductors the tach would jump randomly, with the inductors (a pair of 20mH ones wired in series) it is matching the TS tach but I can't be 100% sure it is working fine since the signal becomes way too noisy (haven't logged it with the "apparatus" plugged in but the values LPG2CV wrote:You need to be cautious of older fw with newer tunes. hamjayahk wrote: ↑Mon Sep 13, 2021 4:35 am Do you need to swap the injector wiring since the stock injectors paired 1-3 and 2-4 instead of commonly 1-4 and 2-3? Wouldn't matter. NickZ. Just received my UA4C vC5 board and while testing it (Nothing wired yet just 12V from a PSU and USB to laptop) I noticed my MAP and BARO sensors are not working correctly. and the car runs terrible. Unanswered topics; Active topics ; FAQ; Search . As the D-Stage manual suggests I've connected Speeduino's IDLE-OUT (pin 37) to the IAC pad on D-Stage. Coil is a Ford wasted spark type for a 4 cyl engine (see pic below) I did a fair bit reading before configuring From what I can tell from the wiring diagram we need Crank and Cam signals, but the VG only has a Crank position sensor. 4, however all of these functions can be reassigned to other ¶ UA4C for Speeduino Seawolf/Sea Fox. It shows values in Tuner Studio, but I feel like it interferes with other sensors and I don't know why. Vauxhall C20ne engine getting started I've used the UA4C board map as that is my preferred target but I noticed some of the UA4C pin assignments seem to cause conflicts when used with the Teensy. BMW M20B23 L-Jetronic to UA4C Sea Fox Here are the pics as promised. I've got a 0. i found a solid state relay deal im gonna try out but the 2nd vvt would be very useful. The engine swap was made as I was struggling with traction and wanted a bigger car but had spent too much time and money rebuilding the engine > hence sx4 4x4 Specs: Wiring description and diagrams for fuel injectors ¶ Injector wiring ¶ Overview. 0L turbo work truck is already covered, but I don't know which will be the first test mule for us. Just use a hose union adapter to the smaller hose. 4 is intended to be integrated more closely into existing wiring, with the aim being that interface boards can be used to easily connect through the IDC40 connector. this can result in data being loaded into the wrong variables. 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. UA4C VC5 White Fang definition/reference file UA4C - Seafox documentation. Speeduino has an onboard socket and jumper system to allow for simple use of a plug in conditioner board. Such signals can be inputted directly from hall or optical sensors, however the common Variable Reluctance (VR) sensor requires conditioning in order to convert its AC signal. it forces the ecu to disconnect from my laptop. Speeduino always fires 1-2-3-4 on the outputs, and; Missing Tooth tells Speedy where TDC #1 is per-revolution (non-sequential like paired or wasted-spark), while; adding a cam sensor signal to Missing Tooth tells it the next cycle after the cam pulse is #1 only. First question is with the hardware aspect of things, the only RPM input is from the ignition module in the distributor. Go to Speeduino r/Speeduino. For discussion of Speeduino compatible boards designed / built by other members of the forum and for guidance around making such a board Search General Discussion / Support / Your Projects. In the meantime, add a tach signal to your input so it sees rpm. 1 year 2002 and my goal is to mount a Speeduino and run the car in a first time.
