It looks like they sell on aliexpress.com too, which is handy for small quantities:

Re: 1970 Datsun pickup L16 TBI conversion
Russian, I think have discovered what is happening regarding tpsmin/max. I'm not sure how, but it appears that the memory offset for tpsmin/max in firmware is no longer the same as in tunerstudio rusefi.ini. The min/max values aren't reversed in tuner studio, rather memory offset in the firmware is ...

Re: 1970 Datsun pickup L16 TBI conversion
Thanks for the suggestions. The TPS ADC values were completely sane (smoothly varied between 74 and 716 while opening the throttle). This makes me fairly certain the issue is in the calibration code. Russian, I tried reversing the calibration values in tuner studio, but it almost seemed like it wasn...

Re: 1970 Datsun pickup L16 TBI conversion
I have added sensors for air temp, coolant temp, MAP and TPS to my bench test setup. Everything is sane except for TPS. The calibration using tuner studio doesn't seem to work right. My closed ADC value is 74, and my open is 716, however if I use these values in tuner studio, it causes the TPS posit...

Re: 1970 Datsun pickup L16 TBI conversion
I'll try to get the data points you want. My drill only goes up to about 2100rpm and at that rate the sensor was only producing maybe 10-15V peak to peak with R111 un-populated. The next step will probably be adding spark on the bench. I think I will also test the injectors on the bench because it w...

Re: 1970 Datsun pickup L16 TBI conversion
Update: I populated R111 with a 22kohm resistor and the false triggers are gone. The circuit still works properly down around 100rpm, so I'm satisfied.

Re: 1970 Datsun pickup L16 TBI conversion
Good to know regarding the MAX9926 input limits/clamping. I actually first noticed the false triggers in rusEFI console engine sniffer with no scope attached. The scope testing was a result of chasing the source of the double trigger. It behaves the same either way. I'll let you know the result, but...

Re: 1970 Datsun pickup L16 TBI conversion
good points, About the max 9926 chip, I see what you are saying. In the below on page 3 it notes the "Watchdog Timeout for Adaptive" is typically 85mS but could be as much as 125mS or as little as 45mS. In the picture you posted, I'm assuming that's your single tooth wheel, running at 480R...

Re: 1970 Datsun pickup L16 TBI conversion
Any how, could you connect the distributor to a hand drill or something to spin it at about the speeds you need? If so, you could connect some spark plugs and make the entire spark system work with out any changes to the engine. You could vary the RPM and validate you are reading the proper RPM, an...

Re: 1970 Datsun pickup L16 TBI conversion
I'm just getting started, nothing is installed in the truck yet. I'll probably start with spark and add fuel later. I have a 40+ psi in tank fuel pump from a honda to retrofit before I can do fuel. The TBI runs at a lower pressure, however it includes a fuel regulator so based on my research it shou...

Re: 1970 Datsun pickup L16 TBI conversion
Thanks for the prompt replies. A1: would it be an option to flip the sensor wires which go into MAX9926? If flipping the wires is not an option I would change the firmware and flip the callbacks in trigger_input.cpp The price of conditional jumps is pretty depressing, I would love not to add another...

1970 Datsun pickup L16 TBI conversion
Hi! Here is the candidate, my 1970 datsun 521, with stock L16 and 4spd manual. Currently it is stock carb and points based ignition. I'm starting with a TBI conversion for simplicity. https://lh3.googleusercontent.com/lFXKvOwx-1Snc7cDR2gTuRdWLu0yh625JUuYmGdPgY56ufi0xok=w1704-h958-no I modified a dis...

Hello
Hi! I've been interested in DIY EFI for a long time, but just recently decided to jump in. I have spent a lot of time back in the day reading about megasquirt, and more recently about FreeEMS, LibreEMS, SpeeDuino , and rusEFI. I actually bought and built a FreeEMS jaguar board, however after buildin...
