Big surprise, didn't get it driving before Christmas. Have gotten it idling nicely now. Might have it all buttoned up by February. :lol: https://youtu.be/HHpHaoW3wjk You live on the edge! https://github.com/rusefi/hw_microRusEfi/issues/203 :) I need to update my 240Z thread. I can confirm that you c...

My second EFI project. I put the Tuned Port Injection intake from a '85 Corvette on a '74 Chevy C10 350. Doing pretty much the same thing I did on the 240Z. Using an HEI distributor and conditioning the tach signal coming out. Using an MRE and driving 2 injectors per injector driver. The goal is dri...

Victory. The Z made it through Hot Rod Power Tour 2021. The MRE ran perfectly for what was at least a 2000 mile road trip; and not once did the engine act up, while idling in the heat, like it did with the carbs. I ended up running with the bare minimum for the entire trip. Used the wideband to tune...

Took the Z around the block for the first time. It's running too rich, but a successful first run nonetheless. Going to add the cylinder head temp sensor before the trip to improve cold starting. A bit cleaner than the last post. Now with more PVC and zip ties, but less fuel leaks! https://youtu.be/...

It lives! It's a twisted together electrical taped temporary mess, but it works. Fuel rail leaks on the end fittings, so I've gotta fix that. And I must've screwed up configuring the 02 sensor pin 'cause I was reading 0v in TS while reading 5v on the multi-meter. Otherwise, it was really easy. Confi...

Last weekend I ended up helping with my friend's project. A '74 Dodge D100. We went and got a 5 speed for it. Going to do a manual conversion. But that's for another weekend. This weekend end I've "finished" plumbing the chassis. The pump. PXL_20210725_002130986.jpg The pump side of the su...

Yup, got 'em. And they're VNLD5090's which are apparently good for 13 amps. Sweet.
Not sure if it's a good idea, but I could fire all 6 injectors at once with a single one of these.

Edit: Typo

I'll have to check to see if I have the 8 amp low side outputs, that's definitely an option if that's the case. My original idea was to pair up the 2.2 amp outputs and use each pair to drive 3 12.5 ohm injectors. A pair should handle 4.4 amps and three injectors should require around 3.6 amps at, wh...

Man, done this like, 3 times now. Pulling a motor is still a ton of work. The O2 sensor bung is in. PXL_20210711_013138981.jpg Think the angle is good. Should live comfortably between the trans and the tunnel. PXL_20210711_055304998.jpg The front ends of the fuel lines have been terminated. The supp...

I have a scheme cooked up for running COP and sequential injection eventually. These engines (the old non-fuel-injected ones) have their fuel pump ran off an eccentric that mounts on the front of the cam. I figure it would be pretty easy to mount a trigger wheel in place of the eccentric and poke a ...

The blue was a nice surprise. I'd only seen pictures of the MRE in red or green.

Got the second VR pickup in the dizzy. Twisted some wires together and got the MRE showing the correct RPM. Progress. Now I gotta get the engine/transmission out to modify the fuel lines and exhaust. And fix the oil pan leak while I'm at it. Nothing to it but to do it. The dizzy PXL_20210701_0343441...

Yeah, the Chevy HEI module doesn't like to share. Wiring the MRE in parallel with the HEI on the VR pickup wires resulted in the HEI getting really hot and the engine not cranking (still carbureted). It ran after I removed the MRE, so at least I didn't fry the HEI. I guess it got at least one good f...

Oh, yeah, I didn't explain the ignition much at all. It's an electronic distributor from the same car as the EFI intake ('75 280Z). It has a single VR coil that I have wired to a 4 wire Chevy HEI igniter. The igniter is driving an MSD Blaster II. I ordered the MRE configured for a VR sensor. My plan...

Hi, I have a Datsun 240Z. It's my fun little money pit. The carbs are fantastic, except when they vapor lock. What a shame. If only the head was crossflow. I've wanted EFI for a while, but it either required coming up with a custom intake for the early (pre-EFI) head or modifying the head to accept ...
