Project stalled for the forseeable future, I broke a rod or something While cranking? While revving? While not rusEFIing? While cranking, I don't even know when exactly it happened and the last time it ran it was on the stock ECU. I plugged the rusEFI back in tonight to test some things, tried to s...

Project stalled for the forseeable future, I broke a rod or something

As far as I can tell the ECU works save for possibly having to tune the VR input. I uploaded a new tune and datalog to rusEFI online, trigger error was incrementing but the trigger events in the log looked okay. I won't have time to troubleshoot until tonight. Never mind I'm a dumbass and was inter...

Do you know part numbers for those while and black ECU headers for me to add on https://github.com/rusefi/rusefi/wiki/OEM-connectors? I don't. All I know is they're made by sumitomo and don't appear in any of the 90s/2000s era catalogs I was able to find, nor have I or anyone else been able to find...

I have a pogo pin adapter but stupidly left my STlink at work and can't flash anything until next week

The first batch of ECUs came! I'm still waiting for some parts to arrive and need to flash firmware onto these so no videos yet

I doubt that TLE8888 driver has manual fully supported and I doubt that we should keep investing in TLE8888. Please consider uaEFI which gives you both MAX9924 and discrete VR with bias control. Thankfully my PnP design is based on uaefi. My solution for now is going to be a VR sensor conditioner f...

I tried cranking it with the mode set to semi auto with no difference. CRANK pad TLE semiauto.png The good news is I'm able to replicate the issue with the MRE off the bike and hooked up to a function generator and power supply! Signal applied to VR+ pin: Fake cam sensor signal 2.png CRANK pad signa...

TLE8888's datasheet Technically we have 'mode' which I believe no one has used ever? image.png Section 10 of the datasheet explains more about this and I think the highlighted part may be the culprit https://www.infineon.com/dgdl/Infineon-Infineon-TLE8888QK-DS-v01_02-EN.pdf?fileId=5546d4624f205c9a0...

TL;DR : One of the pulses from the camshaft sensor is half of the amplitude of the other two, feeding the MRE a fake cam sensor signal with all the pulses close to the same amplitude does not produce the problem I'm seeing. Maybe the amplitude difference is tripping up the TLE8888 somehow? Context:...

Ignore that, I was very confused. My problem is I'm having trouble setting trigger offset. I can fiddle with offset so my timing light has the marks lining up correctly when cranking, but small changes in offset of 5-10 degrees seem to correspond to large changes in actual ignition timing and vice v...

The cam sensor looks right. The crank reluctor is missing two teeth. The right side of this wiring diagram has drawings of the crank and cam wheels and I've attached a service manual page showing what the crank and cam sensors look like https://vfrenjoyer.neocities.org/VFR%20Wiring%20Layers%20hires...

I've spent the past few days working out kinks unrelated to the tune and trying to get my bike started with no luck. I'm very stupid and somehow forgot the VFR has a funky firing order which is usually one of the first things every VFR owner mentions when evangelizing how great the VFR is. vfrfiring...

Updated the firmware and now I see spark while cranking!

since I don't have the crank sensor connected.

please elaborate. Do you plan to have crank sensor connected eventually?

Not with the microrusEFI as it only has a single VR sensor input. I'm very sorry, I thought I mentioned this only had the cam sensor connected but I forgot to!

https://rusefi.com/forum/viewtopic.php?t=1030 The "CBR600" trigger appears to be based on a modified CBR600f4i crank trigger with two teeth removed, which I assume is totally unrelated to this since I don't have the crank sensor connected. According to a wiring diagram I found the stock tr...

I'm trying to set up trigger offset but don't get any spark when cranking. I've confirmed triggering the spark plugs via the bench test menu works so I assume I have the trigger set up wrong

Funny you say that, I have a dead SVX sitting in a storage unit and just made a proteus to 96-97 OBD2 era SVX wiring table for a fellow SVX owner today. The igniter off a SVX (22438AA050) can be added to the list of working ignition parts, and I have to imagine similar nissan versions for VG30s call...

Hello! My personal website logging this build can be found here: https://vfrenjoyer.neocities.org My goals with this build are to A: Make my bike faster and B: Come up with a reliable turbo setup other people can easily copy while minimizing the time spent with an unridable bike or chasing electrica...

Analog volt inputs have a 500k pulldown, so they're effectively not there at all. Like Andrey mentioned, the analog temp inputs have a 2.7k pullup to 5v. You could always wire your coolant sensor to a voltage input instead, which would probably work. Knock and VR sensor are a different story.... le...

WARNING: THIS THREAD WAS BORN OF STUPID IDEAS Is the input impedance on the analog in pins on a proteus high enough that it and a car's stock ECU could be connected to a sensor output without the use of a buffer amp? My plan is to share Crank, coolant and air temp, MAP, TPS, and maybe Knock sensor ...
